Q

Which of the following regarding automatic external defibrillators is false?
a) AEDs with paediatric systems should be used for children

A

d) IV and cardioresp monitor are not on the list because basic life paramedics don’t have training in them
the main change to what pre-hospital providers should have is the addition of AED
children with sudden witnessed collapse - at risk of pulseless ventricular tachycardia or ventricular fibrillation ->need AED
other equipment:
- see the list, includes airway equipment, defibrillation, immobilization, infection control, ob/neonatal supplies, other miscellaneous
- statements are for basic life support trained paramedics, so no IV or Cardioresp monitor is included on the list, since they are not trained in this, don’t have intubation equipment on the list either but do have oral airway, O2 and bag mask, nasopharyngeal airway, suction (special paramedics are but this statement doesn’t cover them) this is to basic minimum equipment needed to transport neonates and children , C spine as well
should have appropriate training and checking of equipment

Q

Which of the following is the most common side effect of ondansetron when used for gastroenteritis?

a) diarrhea
b) drowsiness
c) hallucinations
d) extra-pyrimidal side effects

A

a) diarrhea is the most common side effect when used for gastro, usually mild and self limiting
no drowsiness with ondansetron (hence the appeal)

selective serotonin receptor antagonist , peak within 1-2 hours rapidly absorbed
safe and effective in cancer patients as well as post-op
low risk of SEs in this population

c) incidence of acute gastroenteritis in children

A

c)false - 1-2 episodes per year in the industrialized world

20% of all outpatient hospital visits by younger children, 200000 hospitalizations per year

meds that are commonly prescribed, promethazine, metoclopramide, dimenhydrinate and domperidone rare (but scary) side effects include drowsiness, extra-pyrimidal symptoms, hallucinations, convulsions, neuroleptic malignant syndrome

Q

Which of the following is not one of the things that ondansetron has been shown to do in RCTs?

a) reduce need for IV fluids in children age 6 months-12 years with gastroenteritis causing mild-moderate dehydration or who have failed ORT
b) reduce frequency of vomiting children age 6 months-12 years with gastroenteritis causing mild-moderate dehydration or who have failed ORT
c) reduce symptoms in patients age 6 months-12 years with gastroenteritis presenting with severe diarrhea
d) may be helpful to reduce hospital admissions of children with gastroenteritis

A

c) is the answer - the only side effect was diarrhea, generally resolved within 48 hours
therefore, shouldn’t use for patients with gastro where moderate-severe diarrhea is the main presenting symptom

single dose
in hospital setting - need more studies to assess its role out of hospital

studies
#1: Freedman - reduced IV fluids, reduced vomiting, no difference in hospital admission
#2: Roslund - less likely to receive iv fluids or get admitted to hospital
#3: Ramsuck - vomited less, less IV fluids, less likely admitted to hospital
meta-analysis by Decamp of these studies and 3 others: decreased risk for further emesis in the ED, IV fluid administration and hospital admission

Q

Which of the following is the most common identified trigger for anaphylaxis?

a) food
b) hymenoptera stings
c) medications
d) infection

A

a) food is the most common identified trigger, then hymenoptera stings (wasps/bees) and medications
a trigger is only identified in 1/3 of cases
cause of anaphylaxis - release of mediators from mast cells and basophils often in response to an allergen
incidence 1-4/1000
when food identified, trigger, peanuts, tree nuts, fish, milk, eggs and shellfish (eg, shrimp, lobster, crab, scallops and oysters) most commonly implicated in fatal and near fatal reactions

Q

Which of the following patients does not meet the criteria for anaphylaxis?

a) child with urticaria and hypotension presenting acutely
b) child with hives and persistent vomiting after exposure to a likely allergen for that child (known allergy)
c) child with stridor and nausea/vomiting that occurs acutely after exposure to a likely allergen for that child (known allergy)
d) reduced BP by 20% after exposure to a known allergen

A

d) needs to be reduction in 30% of the BP or low BP based on age norms
the 3 criteria for anaphylaxis:
FOR NEW PATIENT
1. acute onset of illness (minutes to several hours) with involvement of skin/mucosal tissue and at least one of either resp compromise or hypotension
FOR KNOWN PATIENT
2. 2 or more of the following occurring rapidly after exposure to likely allergen:
- urticaria
- resp sx
- GI sx
- reduced BP or end organ dysfunction
3. reduced BP after exposure to KNOWN allergen for that patient

Q

Which is the recommended body weight for the epipen Jr?

A

c) epipen Jr 10-25 kg
doses of epipen Jr: 0.15 mg and epipen 0.3 mg
does for 10-25kg and >25 kg person
risk of epipen vs drawing up dose for smaller person, is risk of delay and wrong dose; need to balance these
physicians should air on the side of caution, inject epinephrine early
for greater than 25 kg, use epipen 0.3 mg dose

Q

Which of the following should be the first step in the acute management of anaphylaxis in the hospital?

a) IV access
b) IM epinephrine
c) cardioresp monitor
d) NS 20 cc/kg bolus
e) intubation

A

b) IM epi is first and most important
dose is 1:1000 epi dose of 001 mg/kg into the lateral thigh
and initiate ABCs at the same time, O2, monitor, IV access (don’t delay epi to get IV)
if severe airway signs, then prepare for intubation **early preparation for airway management is crucial cause it may be a difficult airway
if cardiovascular compromise then give 20 cc/kg NS bolus to replenish volume; up to 35% of blood volume can be lost in first 10 minutes because of increased vascular permeability

Q

Which of the following is false?

a) only anaphylactic patients presenting with hypotension need an IV
b) an IO should be placed if you can’t get an IV and the patient is hypotensive and poorly perfused
c) ideally patients with anaphylaxis should be placed supine or in the Trendelenburg position
d) cetirizine is one of the second line medications for the treatment of anaphylaxis

A

a) false - because you can lose your up to 35% of blood volume can be lost in first 10 minutes because of increased vascular permeability, ALL patients with anaphylaxis should get 2 large bore IVs

the rest are true

b) if no IV and poor perfusion/hypotension, then IO
c) helps to increased blood return to the heart/prevents pooling of blood in the extremities
d) true - second line includes H1 and H2 blockers, salbutamol, corticosteroids

Q

Please match up the effect of epi and the mechanism of action

a) alpha adrenergic
b) beta-1-adrenergic effects
c) beta 2 adrenergic effects
d) concentration used for anaphylaxis

  1. bronchodilation and reduction of inflammatory mediator release
  2. 1:1000
  3. increased vascular resistance
  4. chronotropic and inotropic cardiac effects
  5. 1:10000
A

a) 3: alpha adrenergic - increases vascular resistance and decreases vasodilation, while decreasing angioedema and urticaria (i.e. alpha tightens it all up) - alpha is arteries
b) 4 beta -1 adrenergic : chronotropic and inotropic cardiac effects (beta one is number 1 and speeds it all up) - you have one heart
c) 1 beta 2 adrenergic: bronchodilation and reduction of inflammatiory mediator release from mast cells and basophils (i.e. like for asthma) - you have 2 lungs
d) 2 1:000 epi dose is 0.01mg/kg (max total dose is 0.5 mg) can repeat every 5-15 minutes

Q

Which of the following is correct

a) cetirazine is a non drowsy H2 blocker
b) H2 blockers such as ranitidine are given primarily when there are GI manifestations of anaphylaxis
c) IM epi works better when given in the deltoid in the arm
d) steroids have shown a proven benefit in the treatment of anaphylaxis in RCTs
e) inhaled salbutamol should only be used for patients with known asthma presenting with anaphylaxis

A

e)true - (not the greatest question I have made here), salbutamol for known asthma and wheezing , can considered inhaled epi for stridor but certainly not proven

c) false, better to give it in the anterolateral thigh - results in higher peak plasma concentrations and peak concentrations achieved sooner than when given in the arm
can repeat ever 5-15 minutes depending on condition

a) false - it is a H1 blocker, it is non drowsy, therefore if the patient isn’t vomiting, it should be your first line choice of H1 blockers
b) false - not according to statement, giving both H1 and H2 blockers together reduces the cutaneous manifestations of anaphylaxis compared to using H1 blockers alone
no RCTs for H1/H2 blockers or steroids
d) false - no RCTs have shown proven benefit, most experts will recommend it steroids onset of action is slow (4 h to 6 h), and that there will likely be little benefit in the acute phase of management (thought to prevent rebound from what I know). oral steroids, if severe, then IV
e) use for patients with bronchospasm/wheezing, known asthma, upper airway obstruction (i.e. stridor)(even though no proof for this indication)

Q

A patient has refractory hypotension after repeated doses of IM epi and fluid boluses, what should you do?

a) give IV glucagon
b) continue giving multiple fluid boluses
c) continue giving IM epi as hypotension will likely improve
d) start IV epi infusion

A

d) start IV epi infusion
- no evidence that repeated IM epi helps with hypotension
- IV infusions of epi have more sustained effect, whereas boluses have more immediate effect
IV boluses of epinephrine may have an immediate effect that is often short lived, accompanied by coexisting concerns for induced cardiac arrhythmias when administered too rapidly
- also co-existing concerns that epi can cause arrythmias with lots of doses
- IV glucagon - for patients who are on a beta blocker, since these patients can have anaphylaxis with persistent hypotension, glucagon activates adenylate cyclase independent of the beta receptor, bolus dose then infusion

Q

How long is the minimum you should you observe patients after anaphylaxis?

a) until symptoms resolve
b) 2 hours
c) 4-6 hours
d) 12 hours

A

c) reasonable amount of time to observe is 4-6 hours, most biphasic reactions will occur within this time
can happen up until 72 hours so may be reasonable in more rural situations to observe longer (12 hours) or to admit to hospital overnight
patients who are more likely to have biphasic reaction : have delayed epi admin, more severe initial reaction, or who needed more than one dose of epi
5-20% of patients can have biphasic reaction, 3% of children have a severe reaction
more severe reaction esp with hypotension or resp symptoms or biphasic reaction should be admitted to hospital, patients with high risk features - asthma, peanut allergy, use of beta blockers, should consider for overnight observation or admission
IV epi/glucagon or major airway symptoms should go to the ICU

Q

Which of the following is not part of the discharge instructions for anaphylaxis?

a) leave the ER with epi auto injector if possible
b) only administer epi after being sure that it is anaphylaxis
c) child should always carry epi with them
d) consider 3 day course of oral H1 and H2 blockers and oral steroids at discharge
e) referral to allergist/immunologist

A

b)false should err on the side of caution and administer whenever symptoms occur after exposure to individuals known trigger

the rest are true
a) should give them a prescription for epi pen, if possible give them an auto injector since they could have a reaction on the way to the pharmacy (biphasic)
c) home and school, ideally two doses at each place (i guess in case the first dose is given wrong)
d) most experts suggest this even though limited data since unlikely to cause harm and may help with faster resolution of symptoms
trict instructions to avoid the allergen
also give them online resources as well as discuss the importance of medic alert bracelet
allergist can provide additional testing
counsel detailed about symptoms of anaphylaxis

b) MDI is more likely to to provoke hypoxemia and tachycardia than a nebulizer
c) MDI with spacer is the best way to delivery B agonist
d) when there is hypoxia, should give O2 by nebulizer

A

b) opposite, when there is no initial O2 need, then MDI is less likely to provoke hypoxemia and tachycardia than a nebulizer

MDI always better to deliver bronchodilator, except when impending respiratory failure
even with hypoxia can give MDI with spacer and nasal prongs at the same time
in children without O2 need, then MDI and spacer less likely to provoke tachycardia and hypoxemia

b) steroids should be used for moderate -severe exacerbation and reduces the risk of hospitalization and risk of relapse
c) IV MgSO4 may improve lung function and decrease hospitalization in children with severe asthma
d) IV salbutamol in severe attacks has been shown to improve pulmonary function and gas exchange
e) mechanical ventilation in the context of severe asthma is associated with increased risk of death

A

a) false - no evidence that useful when used beyond first hour, the other 2 are benefits that have been shown when used with beta agonist in the first hour

severe exacerbation- should get IV steroids; methylpred or hydrocortisone

there rest are true, MgSO4 should monitor for hypotension and bradycardia, consultation with ICU or respirologist recommended
In general, inhaled drugs may have a limited effect in patients with nearly complete airway obstruction and have practical limitations in ventilated patients.
IV salbutamol- cardiac effects include tachycardia and arrhythmia, so should have continuous cardiac monitoring
intubation for asthma - increased risk of bad outcomes from pneumothorax and/or from increased intrathoracic pressure leading to cardiovascular collapse
26% of children intubated for asthma have these severe side effects, so should talk to ICU for these

other for severe ICU who don’t respond to anything: aminophylline, heliox

hyperchloremic metabolic acidosis - has been reported preoperatively, not as much when used for maintenance

headache, lethargy and seizures, and potentially even respiratory and cardiac arrest secondary to brain stem herniation ->because of higher brain/intracranial ratio children more likely to have this consequence

hospitalized children - release more ADH, impaired ability to excrete free water, and also get more free water in hypotonic fluids

Q

Which of the following is not required monitoring for IV fluids?

a) electrolytes prior to starting
b) bid electrolytes for kids with impaired renal excretion
c) monitor urine output
d) daily monitoring of weight

A

b) only daily electrolytes is fine in these kids

statement says do lytes before starting in hospitalized kids , should check lutes daily (more often if risk of renal problems/excretion)

need daily monitoring of urine output and input
should be aware of symptoms of hyponatremia
headache, nausea and vomiting, irritability, decrease in level of consciousness, seizures and apnea.

A

d) should treat hypovolemia, however intracranial blood loss unlikely to lead to hemodynamicaly significant blood loss (exception is scalp or IC bleeding in a young infant
unlikely to results
history should include mechanism, LOC/seizures, presenting symptoms (include LOC, worsening headache or vomiting), medical history of head injury, medications, bleeding, neurological disorders
always consider abusive head trauma

Q

A 3 year old presents with fall from coffee table landing on head. He had a brief loss of consciousness, but is now conscious. They are opening eyes spontaneously , irritable and crying, and moving limbs spontaneously. Mom says that he is complaining of a headache. What is your management?

a) discharge home with instructions for mom
b) immediate CT head
c) close clinical observation in ER for 4-6 hours with consideration of CT scan if symptoms persist/worsen
d) none of the above

A

d) for mild injury, with persistent symptoms of headache and/or vomiting, observe for 4-6 hours, if symptoms worsen then should do a CT. If there is LOC then need to observe also. if symptoms improve and GCS 15, can d/c home with instructions to return if worse (LOC, vomiting, headache). If don’t improve, admit, vitals and LOC q2-4 hour, CT if symptoms after 18-24 hours if not already done.

skull X ray also indicated when abuse is suspected

52
Q

Based on the CATCH rules, which of the following is not an absolute indication for CT head?

a) focal neurological findings
b) clinically suspected open or depressed skull fracture
c) widened or diastatic skull fracture on X ray
d) known coagulation disorder

A

d) known coagulation disorder is on the list of relative indication for CT head
the other 3 are the absolute indications for CT head

CATCH rules -
low probably of finding something on CT, high radiation and need for sedation in some cases - reasons why work has been done to determine who needs a CT head.
CATCH rules - focus more on things that the Absence of which will stop need for CT - may actually lead to more CT scans being performed
98% sensitive

a) leptomeningeal cyst associated, should arrange follow up

need to observe regularly/closely and for longer in babies

55
Q

What is the cause of increased ICP in epidural hematoma?

a) mass effect from bleeding
b) vasogenic edema
c) infection
d) none of the above

A

a) mass effect from bleeding in epidural and subdural hematoma

in diffuse axonal injury, vasogenic edema is the cause of increased ICP

56

a) normal ICP and cerebral perfusion pressure
b) maintain cool (35-36 C) core body temperature
c) maintain normal oxygenation and ventilation with mechanical ventilation
d) maintain normovolemia and avoid hypotension

A

b) FALSE - should maintain a NORMAL core body temperature

the other measures are true
other things to do include: continuous monitoring of vitals and end-tidal CO2
provide sedation and analgesia
should refer to trauma centre
need continuous monitoring on the transport

57
Q

A 4 year old patient falls from the monkey bars and hits his head. He is noted to have a seizure immediately after his fall. He is now back to baseline with a normal neurological exam and has a normal CT head. What is your management?

a) transfer to a tertiary care centre
b) admit for 24 hours
c) discharge home with instructions for family
d) MRI head

A

c)patients with impact seizures or an isolated post-traumatic seizure shortly after the event, but whose neurological examination and imaging are normal, are at low risk of further complications and may be discharged.IMPACT seizure - seizure that occurs immediately after impact,

58
Q

Which of the following is not a risk factor for post-traumatic seizures?

a) open/depressed skull fractures
b) cerebral edema
c) severe head trauma
d) older age

A

d) younger age is a risk factor
the other 3 are risk factors for post traumatic seizures
most occur within 24 hours, and rarely beyond 7 days
incidence 5-6.5% but may be as high as 30-35% in severe head injuries
post traumatic seizures (other than impact seizures) can contribute to secondary head injury
administering phenytoin to prevent seizures post head injury doesn’t have a lot of evidence proving it, but is still commonly used post severe injury

63
Q

Which of the following metabolic abnormalities is not commonly associated with causing status epileptics?

a) hypercalcemia
b) hyperglycemia
c) hypoglycemia
d) hyponatremia

A

a)
hypercalcemia is not listed - hypocalcemia is more commonly associated with seizures

there others are listed

64
Q

Which of the following is the most common cause of prolonged convulsive status epileptics?

a) CNS infection
b) drug overdose
c) prolonged febrile convulsion
d) brain tumours

A

d) 23-30% - prolonged febrile convulsion
most common cause of convulsive status epileptics is prolonged febrile seizure
other common acute causes (17-52%) include infection, drug overdose/withdrawal/underdose, metabolic abnormalities, structural causes (more remote 16-29%)
idiopathic 5-19%

65
Q

Which of the following is not part of the acute management of a child with status epileptics who is desating?

a) place on side
b) pry open teeth
c) suction visible secretions
d) place on back and do jaw thrust or chin lift after suctioning
e) 100% O2 and cardioresp monitoring

A

b)do not pry open the teeth
the other steps are reasonable

risk factors for airway and ventilation being at risk include a clenched jaw, poorly coordinated respirations, and production of secretions and vomitus, hypoxia frequently present
consider assisted ventilation if respiratory depression or low sats despite 100% O2

66
Q

Which of the following is the not a particularly ominous sign in a child with convulsive status epileptics

a) hypotension
b) bradycardia
c) tachycardia
d) poor perfusion

A

c) tachycardia and hypertension and common with seizures
hypotenion, bradycardia and poor perfusion are ominous signs which signify severe hypoxia->need immediate airway management (bag/mask or intubation), IV access and glucose

67
Q

A 2 year old child has been having GTC seizure for 10 minutes, 2 doses of ativan have been given. Still seizing. What should you do next?

a) more ativan
b) try diazepam
c) give phenobarbital load
d) give phenytoin load
e) midazolam infusion

A

d)phenytoin load
phenobarb is used for neonates and for people who are already on phenytoin
need IV/IO to give second line
ask about seizure disorder, other symptoms (eg, fever), medication usage and allergies to medications.

common mistakes in treatment
giving more than two doses of benzo and delaying second line treatment, delay in intubation and midazolam infusion

68
Q

A patient arrives seizing for 10 minutes, bedside glucose is 2.5 mmol/L. ABCs are stable. has received 2 doses of SL benzo. What is the next step?

a) give more benzo SL
b) give 2-4 ml of D25W or 5 ml of D10W (0.5g/kg) IV and recheck glucose in 3-5 minutes
c) load with fosphenytoin immediately
d) intubate

A

b) need to correct the sugar before doing other things
if persistently hypoglycaemic may need another bolus
hypoglycemia is

69
Q

Which of the following is false of benzodiazepines?

a) work equally IV and sublingual
b) administering within 20 minutes can stop 70-85% of seizures
c) buccal and intranasal midazolam have been shown to be the most effective non IV benzo medications to stop seizures
d) intranasal midazolam has been shown to be as effective as IV lorazepam to treat prolonged febrile convulsions in one study

A

a) false works better IV, so should get IV access ASAP

the rest are true
b) true , very effective at stopping seizure if given early
studies: buccal midazolam better than rectal diazepam
intranasal midazolam as effective as IV lorazepam
some would say that if available, buccal midazolam or intranasal midazolam should be first line for children without IV access

70
Q

All but which of the following is an advantage of IV lorazepam ?

a) less respiratory depression than IV diazepam
b) repeat doses continue to be very effective
c) longer acting anti-convulsant than IV diazepam
d) more effective at stopping seizures than phenytoin and IV diazepam

A

b) repeat doses are less effective (17% vs 85% for first dose)

treatment with more than 3 doses of IV medication is associated with respiratory depression
if pre-hospital benzos given, reasonable to give one does of IV benzo in hospital.
if don’t have access, very important to give the two doses of benzo through whichever route is needed

71
Q

Which of the following is false of phenytoin and fosphenytoin?

a) less likely to cause respiratory depression than phenobarb
b) less likely to cause altered LOC than phenobarb
c) should be given in glucose containing fluid
d) phenytoin can cause “purple glove syndrome”
e) side effects of both include bradycardia, arrythmias and hypotension

A

c) opposite - don’t give in a glucose containing solution, it will precipitate

purple glove syndrome - severe SC irritation characterized by edema, discolouration and pain distal to the site of injection
doesn’t happen with fosphenytoin, which is the water soluble prodrug of phenytoin
fosphenytoin can be given more rapidly and also IM, but more expensive and not as easily available
need continuous BP and ECG monitoring during infusion or either drug

72
Q

Which of the following is false?

a) phenobarbital generally causes more respiratory depression than phenytoin and is less effective
b) dose is 20 mg/kg in NS, should be given over 20 minutes
c) rectal route is the recommended route for paraldehyde, although it is used very uncommonly
d) fosphenytoin is the best treatment choice for neonatal seizures

A

d)false - phenobarb is used for neonatal seizures and also for kids already on phenytoin maintenance

if patient already on phenytoin or phenobarb - can give 5/kg but then should wait for levels to give more

overall not great studies
more resp depression especially when given with benzo
sedation, respiratory depression and hypotension,

paraldehyde - bad side effects with IV (include cyanosis, pulmonary edema, cough, hypotension) therefore should only consider rectal route with dilution with oil; many people don’t recommend it, only say to use it if no IV

other potential options:
interest in valproic acid as a second line treatment
studies - some show similar efficacy to phenytoin to less side effects (esp no resp or CV compromise)

73
Q

Which of the following patients might one consider a trial of pyridoxine (B6)?

a) 10 month old
b) 20 month old
c) 24 month old
d) 36 month old

A

a) consider for children <18 months who may have an undiagnosed metabolic condition such as pyridoxine dependant epilepsy

74
Q

A 14 year old arrives in status epileptics, which has resolved after 2 doses of benzodiazepines. He has a temperature of 39 C and looks unwell. What is the most important step in management?

a) lumbar punture
b) broad spectrum antibiotics
c) CBC
d) blood culture
e) head CT

A

b)if suspect sepsis, most important to give antibiotics (should definitely do as much as possible to get cultures first, but don’t delay antibiotics for the LP)

investigations:
CBC, glucose, culture (if suspect sepsis), lytes
if on anticonvulsants, should measure levels
in certain cases, do calcium/magnesium/LFTs, lactate and ammonia
urine and blood tox can be assessed
always consider intoxication
LP after patient is stable and no signs of increased ICP and convulsion stopped, if suspect sepsis should give antibiotics asap
if have focal signs, history of trauma, increased ICP or suspect herniation, do CT after stabilizing ABCs

75
Q

When should one consider starting midazolam infusion?

a) after 2 hours of seizure
b) after 1.5 hours of seizure
c) after 1 hour of seizure
d) after 20-30 minutes of seizure

A

d)after refractor status (see definition below), unlikely to respond to other meds, so should consider midazolam infusion within 20-30 minutes

refractory status - if no improvement after 2 different anti-epileptics , some places have a time specification also (longer than 30 or 60 minutes)

1st line for refractory status - most common is midaz, low BP is most common side effect
thiopental another option
others should be used with expert

if a child doesn’t recover LOC as expected after seizure or if paralytics are being used, then should do EEG to rule out non-convulsive status, if no EEG available then do empiric treatment

76
Q

Which of the following should be the initial step when responding to a cardiac arrest?

a) re-position airway and suction
b) give O2
c) start an IV
d) start chest compressions

A
d) start chest compressions 
new guidelines (2010) emphasize that chest compressions should be the first step
in the hospital, can do this concurrently while another rescuer takes care of airway and ventilation
77
Q

Which of the following is the appropriate ratio of chest compressions to ventilation in a code with 2 responders in an unintubated 2 year old girl?

a) 3:1
b) 100 compressions per minute with 8-10 breathes / minute
c) 15:2
d) 30:2

A

c) 15:2 is the ratio for two rescuer CPR
30: 2 for one rescuer CPR
3: 1 for neonates

if patient is intubated, then do continuous compressions at 100 /minute with 8-10 breathe/minute, do not pause for CPR

78
Q

Which of the following statements is not true?

a) Chest compressions should have a depth of 4 cm in children and infants
b) Compressors should switch every 2minutes
c) should not pause more than 5 seconds for compression switches and limit pulse checks to 10 sec
d) most arrests in children are asphyxial in nature

A

a) 4 cm in infants, 5 cm in children, should be 1/3 of the AP diameter of the chest

the rest are true
because most arrests are asphyxial in nature, ventilation is very important, **with the new guidelines, the emphasis is on early chest compressions, which is better than no chest compressions at all.

79
Q

An asymptomatic six-year-old boy with a family history of sudden death is being evaluated in the cardiology clinic. While visiting the hospital cafeteria, he suddenly collapses, becomes unresponsive and has only gasping respirations. As a health care provider, what should be the next steps?

a) look, listen and feel
b) initiate CPR immediately
c) may pulse check for no more than 10 seconds then start CPR
d) none of the above

A

c) is the answer

no longer have look, listen and feel in the algorithm
for lay people, should check a) responsiveness b) breathing ; if not responsive and not breathing normally (including gasping) then should start CPR ASAP

HCP can check for a pulse for no more than 10 seconds - if no pulse or unsure about pulse, start CPR

80
Q

Which of the following is not the best place to check for a pulse when about to start a rescucitation?

a) brachial in an infant
b) radial in an infant
c) femoral in a child
d) carotid in a child

A

b) radial in an infant not the recommended place to check
the others are:
for infant, brachial, for child, femoral or carotid

81
Q

Which of the following is the recommended method of defibrillation in infants?

a) adult AED
b) AED with paediatric dose attenuator for children

A

d) manual defibrillation is preferred for infants
dose initial dose should be 2-4 J/kg, later doses should be between 4J/kg and not more than 10 J/kg

AEDs CAN be used for infants and children but not the best choice
if you need to use an AED, use a paediatric dose attenuator if

82
Q

Which of the following is sometimes recommended post cardiac arrest in children ?

a) hyperoxemia
b) maintaining O2 sats between 89-94% with O2 therapy
c) therapeutic hypothermia
d) none of the above

A

c) therapeutic hypothermia
if the patient is comatose after resuscitation, should consider therapeutic hypothermia, temperature of 32-34 C rectal, need expert consult for this (don’t get confused, it is okay for post cardiac arrest, remember enter boy, not post head injury)

hyperoxaemia can increase the oxidative injury during repercussion
O2 sat target should be 94-99% (as a saturation of 100% corresponds to a partial pressure of oxygen in arterial blood of between 80 mmHg and 500 mmHg…?)

83
Q

An obese 10 year old girl presents with a wide complex tachycardia with a rate of 180. The child is hemodynamically stable. Which of the following is false?

a) can try adenosine treatment
b) should calculate dose of medications based on ideal body weight
c) WPW is a contraindication to adenosine treatment
d) should only be used for regular, monomorphic rhythms

A

b) doses should be calculated based on actual body weight, up to adult maximums (if not known, use length based tapes because this is more accurate than age based or observer based methods)
because this is a wide complex tachycardia (defined as QRS>0.09) which can be ventricular or supra ventricular in origin, can try adenosine to distinguish the 2 as long as the patient is stable
use only if regular monomorphic rhythms, and avoid if patient with known WPW presents with wide complex tachycardia

84
Q

Which of the following is true?

a) crystalloid has been shown to be more effective than colloid solution during resuscitation for septic shock
b) etomidate should be used routinely for intubation in septic shock
c) etomidate has been associated with increased mortality in children
d) cricoid pressure is recommended during intubation to decrease aspiration

A

c)TRUE etomidate is a sedative, it has been associated with increased mortality
should not be used routinely for intubation in children
DOES have less hemodynamic impact
But has been associated with adrenal suppression in adults and children as well as increased mortality therefore should not use routinely
insufficient evidence to recommend cricoid pressure to decrease aspiration, might slow down intubation or make it harder

85
Q

Which of the following is the appropriate size of cuffed ET tube for a 4 year old child?

a) 4
b) 4.5
c) 5.0
d) 5.5

A

b) 4.5

can use cuffed and uncured tube to intubate children
for children >2 year old, formula of 3.5 + age/4 can be used
therefore 4.5 is the appropriate size
for uncuffed, add 0.5 (so would be 5.0 uncured)
foruncuffed tube, children<1 use 3.0 tube, for children between 1-2 use 3.5 tube

in certain settings, the use of cuffed endotracheal tubes may help to decrease the risk of aspiration and reduce the need for reintubation.

three-quarters of all in-hospital paediatric cardiac arrest victims still die.

Methods, such as team training with realistic patient simulators, debriefing with standardized scripts and video-based learning with a ‘practice while watching’ approach, may help to consolidate learning and, ultimately, lead to improved patient outcomes from cardiac arrest.

86

Q

How does steroids help with asthma?

a) earlier discharge
b) decreased hospitalization
c) decrease chance of relapse
d) all of the above

A

may reduce the risk of hospitalization and risk of relapse from treatment

Mg: improves resp function, decreases admission

89
Q

What are complications of intubation in asthma?

a) CV collapse
b) decreased venous returne
c) pneumothorax
d) increased death risk
e) all of the above

A

e) all of the above

90
Q

True or false - anaphylaxis can occur a few hours after exposure

A

true - usually within minutes but in rarer cases can happen a few hours after

91
Q

True or false - epinephrine can cause harm in healthy individual and should be given with great caution

A

false - in heathy individuals, should not cause harm if given unnecessarily

epi is the first line med to treat, don’t give antihistamines or asthma meds instead, if you give epi need to to go hospital (ideally bia ambulance) even if they are a lot better, need more epi for the transport

no one in anaphylaxis can fully resuscitate themselves - may need help, especially kids

92
Q

True or false - individuals who are feeling faint or dizzy because of impending shock should lie down

A

true - they should lie down unless they are vomiting or having severe resp symptoms
should raise the legs, help increase blood flow
if vomiting, put them on their side
if having trouble breathing, keep them sitting up.

93
Q

What are 3 recommendations you should give to a patients with anaphylaxis

A
  1. carry auto injector at all times when age appropriate
  2. wear medical identification - i.e. medic alert bracelet
    regular practice with an auto-injector for either the allergic person or others (i.e. school staff), if they are in the wilderness should pack a back-up injector
  3. staff training of school staff who are in regular contact with the student at risk

Q

Name some risk factors for severe anaphylactic reaction

A

can’t always predict who will have more severe reaction, however, those with asthma and who have had previous anaphylaxis are at increased risk
avoid allergen only way to prevent
can try to reduce exposure
Factors that may increase the risk of a severe anaphylactic reaction:
1. anaphylaxis and asthma - children with both, more likely to have severe breathing problems when experiencing an anaphylactic reaction, in cases where an anaphylactic reaction is suspected but there is uncertainty whether or not the person is experiencing an asthma attack, epi should be used first
epi can be used to treat life-threatening asthma attacks as well as anaphylactic retains
should carry puffers with their epi
2. under-utilization and delay in the use of epi.
3. underlying cardiac diseases : some meds can interfere with epi
Other factors: previous history , age

95
Q

You are discharging a patient with anaphylaxis from the ER. What are 3 important things to do

A
  1. give them auto-injector prescription and make sure that it is immediately filled
  2. teach them how to use the auto-infector
  3. make sure they have follow up with their physician including referral to allergist
  4. teach them signs of anaphylaxis
  5. tell them to wear a medic-alert bracelet
  6. have a written anaphylaxis emergency plan
96
Q

True or false - anaphylaxis can occur without hives

A

true , it can
never ignore any of the signs
most dangerous are airway or hypotension

97
Q

Most common triggers for anaphylaxis

A

foods
insect stings

another cause of life threatening - latex allergy, less common, is exercise

98
Q

What are the priority allergens as per Health Canada

A

Fish , shellfish, crustaceans, sulphites (a food additive)

99
Q

What are some common side effects of epi?

A

rapid heart rate, pallor, dizziness, weakness, tremors and headache
mild, better in a few hours
NO CONTRAINDICATIONS to using epi for life-threatening allergic reaction, in normal individuals, epi will no cause harm if given unnecessarily

100
Q

Name 2 medications that may interfere wight he action of epi and worsen the allergic reaction

A

cardiac disease/high BP meds

  1. beta-blockers
  2. ACE inhibitors
101
Q

How many children with anaphylaxis do not report a previous episode?

A

65% of children (and 25% of adults) don’t report a previous episode
although previous history of anaphylaxis is a strong predictor of future anaphylaxis

102
Q

What age group has the highest incidence of anaphylaxis?

A

0-19 year old highest
food most common in children, adolescents and adults
middle age and older - more likely from meds and insect venom

103
Q

Which patients might you want to observe for longer than 4-6 hours after anaphylaxis in the ER?

A

patients with asthma - most deaths happen in these individuals
4-6 hours in general, to watch for biphasic reaction
also think about people that live far away

in general, if people feel unwell, advise them not to go to the bathroom

104
Q

True or false - auto-injectors should be kept in locked cupboards or drawers

A

FALSE - should be kept in locations where they are easily accessible, but out of reach of young children
should not be exposed to extreme cold (fridge/freezer) or heat (glove box in a vehicle)
by age 6-7, kids should carry their own epinephrine (carry in a waist pack)

105
Q

A parent is worked that the odor of peanut butter can cause an anaphylactic reaction. what do you tell them

A

it is the protein in a food which causes an allergic reaction, inhalation of airborne peanut protein can cause reactions, though usually not anaphylaxis . the door has not been shown to cause an anaphylactic reaction as the smell does not contain the protein.

in contrast, vapor/steam from cooking fish can trigger asthma or even anaphylaxis

shouldn’t share utensils in for allergic kids, try not to involve foods in rewards systems, clearly label foods , no eating during travel on school buses

106
Q

True or false - hand sanitizer can remove peanut butter residue as well as soap and water

A

false - hand sanitizer isn’t as effective, children should wash their hands with soap and water before and after eating

kids with allergies also shouldn’t eat if they do not have an auto-injector with them, be cautious about foods prepared by others

107
Q

What are some interventions that individuals who are allergic to insect stings can do in the summer

A

stay away from areas where there are lots of insets, wear light colours, avoid loose flowing garments or hair that could entrap an insect, wear shoes instead of sandals, avoid scents, drink from cups rather than cans,

108
Q

Which type of allergies can we consider immunotherapy for

A

venom immunotherapy - a desensitization program which is highly effective for anaphylaxis to insect bites

109
Q

What are the important components of an anaphylaxis plan for a school?

A

needs to be written
1. should not imply a guarantee or that there is zero risk, school communities should strive to create an environment that is described as allergy-safe rather than allergen-free
should prepare and address role and responsibilities
communication strategy, so everyone including subs is trained and knows what to do

110
Q

A parent wants your advice on filling out a form that talks about the school’s responsibility in the event that their child has an anaphylactic event at school. Which of the following is false?

a) complete a write anaphylaxis emergency plan
b) talk to school staff in advance of field trips
c) should sign a waiver that absolves the school of responsibility if the epi is NOT injected
d) provide consent that the school can give the kid epi if they consider it necessary in an allergic emergency

A

c) FALSE - should not waive this responsibility

rather, should provide consent so that school staff use epi when they consider it necessary in an allergic emergency
should also complete an anaphylaxis er plan with child’s photograph and allergy, emergency contact numbers, emergency protocol, signature of a parent/guardian, and if needed signature of physician
provide non-perishable foods and safe snacks for food-allergic children
talk to school staff about field trips
