Q

Explain asthma

A

Asthma is a common condition caused by narrowing of the small air passages in the lungs. The narrowing happens when air passages become swollen and inflamed, causing more mucus to be produced. In addition, the muscle bands around the air passages become tighter. These changes make it harder for air to get in and out of the lungs, and cause wheeze, cough and problems with breathing.
Asthma is a chronic inflammatory disease of the airways characterized by reversible airways obstruction and bronchospasm.
Exacerbations in children are often precipitated by a viral infection.
Asthma increases the risk of fatal anaphylaxis

Q

examination of severity of asthma

A

Wheeze is not a good marker of severity.
The most important parameters in the assessment of the severity of acute childhood asthma are:

general appearance/mental state and;
work of breathing (accessory muscle use, recession)
Initial SpO2 in air, heart rate and ability to talk are helpful but less reliable additional features.
Tachycardia can be a sign of severity but is also a side effect of beta agonists such as salbutamol.
Wheeze intensity, pulsus paradoxus, and peak expiratory flow rate are NOT reliable. A silent chest with no wheeze may herald imminent respiratory collapse.
Asymmetry on auscultation is often found due to mucous plugging, but warrants consideration of foreign body.

Children with respiratory distress should have minimal handling.

Q

types of respiratory failure

A

Type 1 respiratory failure occurs when the respiratory system cannot adequately provide oxygen to the body, leading to hypoxemia. Examples include pneumonia, pe. Treatment, giving supplemental oxygen, positioning

Type 2 respiratory failure occurs when the respiratory system cannot sufficiently remove carbon dioxide from the body, leading to hypercapnia. Examples: neurological disorder (MS), Copd, head and neck injury, APO, drug induced. Treatment CPAP because it opens the alveoli which increases the exchange of cases

Q

APO

A

APO – fluid overload of the lungs, could be caused too much iv fluids or CCF, left ventricular failure causes APO because its connected to the lungs. Symptoms: SOB, pink frothy sputum, hypertension, tachycardic
Treatments: CPAP helps with apo and it forces the fluid out, could also use diuretics, or dialysis . gtn
APO but hypotensive don’t give diuretics because they could arrest so you give inotropes (aramine to get blood pressure up first without giving to much fluid)
Diagnosis: To confirm APO chest xray, but you do a respiratory assessment first and will hear loads of crackles.

Q

differences of children anatomy in relation to breathing to adults

A

Anatomy of children’s ribs is they are more horizontal than adults and adults ribs go round the lungs so children can’t get as good of an expansion in their breath.
Children also have smaller airways
Children are mouth breaths and have bigger tounges, more soft tissue, smaller pharynx

Q

sepsis vs infection

A

Sepsis vs infection: Sepsis occurs when your body’s immune system starts to send infection-fighting chemicals throughout your body rather than just to the infection itself. These chemicals cause inflammation and start to attack the healthy tissues. Your body is no longer fighting the infection, it’s fighting itself.
Sepsis you’re at risk of organ dysfunction
Lactate can indicate tissue hypoxia so its an indicator of sepsis
Anyone that have had surgery are at risk of sepsis same with babies and elderly

48
Q

explain taking blood cultures for treatment of sepsis

A

Blood cultures from 2 sites as the results are more systemic and give a better more accurate reading , blood cultures are done before antibiotics to make sure you don’t mask the problem and give the specifically needed antibiotic

A

protein that are released when there is death/insult or injury in or to the heart
Serial troponins: 6 hourly

54
Q

explain 2, 3 and AVF inferior AMI etc

A

need to answer

fact: we don’t normally give GTN to inferior because we have less pre load so we couldn’t have the volume due to the vasodilated. So there would be not enough load to contract

55
Q

explain angina and unstable angina

A

chest pain to due a partial or complete blockage such a plaque build up or thrombus causing an insufficient amount of blood getting to the heart
Stable: when you exercise it causes vasoconstriction then the partial blockage has less room for the blood to go through causing the chest pain on exertion. So it is resolvable as when the vessels dilate again it feels better
Unstable: complete blockage in the vessels causing chest pain even at rest and vasodilating doesn’t resolve the issue as the vessel is completely blocked.

57
Q

Angio treatment

A

PCI – they like people to have it within 90 minutes. Insertion into the heart to get rid of the blockage

If no PCI facilities they go for fibrinolytic therapy (blood thinner) streptokinase, amylase, alteplase

58
Q

alteplase

A

Alteplase is a fibrinolytic agent; it also is referred to as tissue plasminogen activator (tPA). Alteplase converts plasminogen to the proteolytic enzyme plasmin, which lyses fibrin as well as fibrinogen.

Q

pancreatitis

A

The pathophysiology of acute pancreatitis is based on the premature activation of the enzymes zymogen and trypsinogen, resulting in local pancreatic destruction and activation of the inflammatory cascade, which causes the systemic inflammatory response syndrome (SIRS) often associated with acute pancreatitis.

The 2 most common causes of pancreatitis are gallstones and heavy alcohol consumption

Bloods for suspected pancretitis: FBC, LFT, U and E’s, CRP, Serum lipase, Serum amylase

65
Q

role of the pancreas

A

The pancreas has dual roles - it is an organ of the digestive system and of the endocrine system. The exocrine pancreas produces enzymes that help to digest food, particularly protein. The endocrine pancreas makes the hormone insulin, which helps to control blood sugar levels

66
Q

Q

Hepatic encephalopathy:

A

This is a condition that happens when your liver is too diseased or damaged to properly process ammonia, leading to a buildup of ammonia in your blood that travels to your brain. It can cause confusion, disorientation and coma. It can sometimes be fatal.
Lactulose binds to ammonia and removes it from the system
KNOW what lactulose it is and how it works^^^^

69
Q

lactulose

A

Lactulose is used to treat constipation

70
Q

frusemide

A

Furosemide is a potent loop diuretic that works to increase the excretion of Na+ and water by the kidneys by inhibiting their reabsorption from the proximal and distal tubules, as well as the loop of Henle. It works directly acts on the cells of the nephron and indirectly modifies the content of the renal filtrate.

71
Q

Refeeding syndrome

A

is a potentially fatal condition, caused by rapid initiation of refeeding after a period of undernutrition. It is characterised by hypophosphataemia, associated with fluid and electrolyte shifts and metabolic and clinical complications.

72
Q

first and second line of defence

A

First line of defence is the skin, mucous
Second line of defence is neutrophils

73
Q

Acute Myeloid Leukaemia

A

A type of cancer of the blood and bone marrow with excess immature white blood cells.
AML progresses rapidly, with myeloid cells interfering with the production of normal white blood cells, red blood cells and platelets.
Symptoms include fatigue, recurrent infections and bruising easily.
Treatments include chemotherapy, other drug therapy and stem-cell transplants.

74
Q

What is neutropenia

A

Neutropenia is not a disease. It is a condition in which you have a low number of neutrophils (white blood cells).

75
Q

S.I.R.S criteria: systemic inflammatory response syndrome

A

Body temperature over 38
Heart rate greater than 90 beats/minute.
Respiratory rate greater than 20/22 breaths/minute
White cell count below 4

76
Q

C. diff

A

also known as Clostridioides difficile or C. difficile) is a germ (bacterium) that causes diarrhea and colitis (an inflammation of the colon

77
Q

Nadir

A

is a term that basically means low point. When a person with cancer reaches their “nadir” following each chemotherapy cycle, it means that the person’s blood cell counts are the lowest they will be during that treatment cycle. Each chemotherapy treatment comes with a nadir period. Within 10-14 days.

78
Q

platelets

A

Their primary function is to prevent and stop bleeding. If a blood vessel is damaged, the body sends signals to platelets which cause them to travel to the injured area. Once the platelets arrive at the site, they clump together to form a clot that helps stop bleeding. A normal platelet count in adults ranges from 150,000 to 450,000 platelets per microliter of blood

When you have a low platelet count, you may have trouble stopping bleeding. Bleeding can happen inside your body, underneath your skin, or from the surface of your skin. You may not have serious bleeding until your platelet count is very low

79
Q

Heparin

A

Heparin injection is an anticoagulant. It is used to decrease the clotting ability of the blood and help prevent harmful clots from forming in blood vessels. This medicine is sometimes called a blood thinner, although it does not actually thin the blood.

80
Q

Brain is made up of: Monroe – Kellie theory

A
  1. Blood 10%
  2. CSF 10%
  3. Brain 80 %
    Monro-Kellie doctrine, or hypothesis, is that the sum of volumes of brain, CSF, and intracranial blood is constant. An increase in one should cause a decrease in one or both of the remaining two.
81
Q

Hydrocephalus

A

is the buildup of fluid in cavities called ventricles deep within the brain. The excess fluid increases the size of the ventricles and puts pressure on the brain. Cerebrospinal fluid usually flows through the ventricles and bathes the brain and spinal column.

82
Q

Cerebral perfusion pressure (CPP)

A

is the net pressure gradient that drives oxygen delivery to cerebral tissue. Calculated by (CPP = MAP − ICP). And its normal range is 60-80
Map of 80 – icp 20 = 60 so that’s good
If map is 60 you want it up as then it would equal 40 so you could give noradrenaline to get the MAP up by increasing blood pressure

86
Q

Metaraminol

A

Metaraminol is the vasoconstrictor of choice for the short-term management of acute hypotension along with fluids such as albumin and can be administered by peripheral intravenous catheter. If low blood pressure persists despite adequate fluid resuscitation, it is usual practice to switch to a noradrenaline infusion once central access is available.

Bowel issues, decreased urine output, UTIs, prostate issues in men, haemorrhoids
Risk of type 2 diabetes, lower temperature
Mobility decline, increased falls risk
Skin more fragile (increased risk of infections), wound healing decline

95
Q

Cardiogenic shock

A

(due to heart problems) – heart has ischemia causing insufficient contraction so not enough blood and therefore oxygen getting to the body causing inadequate supply and then the body goes into shock. Causes: heart attack, ischemia disease, pericarditis
Treatment:

96
Q

Hypovolemic shock

A

Hypovolaemic shock: life-threatening condition that occurs when the body is not getting enough blood flow. With bleeding we get: Decreased circulating volume – decreased pre load – decreased cardiac output – decreased blood pressure

MORE.

97
Q

Anaphylactic shock

A

(caused by allergic reaction)
Anaphylaxis causes the immune system to release a flood of chemicals that can cause you to go into shock — blood pressure drops suddenly and the airways narrow, blocking breathing.
Increases vascular permeability and vasodilation leading to hypo perfusion of tissues the body responds to these changed increasing heart rate and contractability. Prostaglandin D functions as a bronchoconstrictor, coronary vasoconstrictor and peripheral vasodilation
Low urine output
Causes: reactions to medications
Treated with adrenaline (vasoconstrictor) and antihistamines

98
Q

Septic shock

A

(due to infections)
Gram negative bacteria is the most common cause of sepsis

99
Q

Neurogenic shock

A

(caused by damage to the nervous system): Neurogenic shock is a critical condition that results from the dysregulation of the autonomic nervous system following spinal cord injury, especially in the cervical and upper thoracic vertebrae above the T6 level, as a result of traumatic events
Because of spinal cord injury the messages of fight, flight or freeze so tachycardia doesn’t show as a symptom, bradycardia, cyanose
Treatment: fluid rescuitation and vasopressors for the hypotension
Atropine for bradycardia
Surgery for spinal cord injury

100
Q

Pathophysiology of shock

A

The fundamental defect in shock is reduced perfusion of vital tissues. Once perfusion declines and oxygen delivery to cells is inadequate for aerobic metabolism, cells shift to anaerobic metabolism with increased production of carbon dioxide and elevated blood lactate levels.

101
Q

symptoms of shock

A

Anxiety or agitation/restlessness
Bluish lips and fingernails
Chest pain
Confusion
Dizziness, lightheadedness, or faintness
Pale, cool, clammy skin
Low or no urine output
Profuse sweating, moist skin
Rapid but weak pulse
Shallow breathing
Being unconscious (unresponsive)

102
Q

treatment of shock

A

Oxygen
Short acting aramine if hypotensive
Fluids such as albumin whilst waiting for blood to come and to create space for the vasoconstrictor
Then long acting vasoconstrictor such as noradrenaline if needed
Treat the underlying cause of the shock eg diahrrea causing dehydration (shock) treat diahrrea will treat the shock

Q

what do you need for a tracheostomy?

A
107
Q

GTN what is it and how does it work?

A

Glyceryl trinitrate, an organic nitrate, is a vasodilator. Its principal pharmacological action is the relaxation of vascular smooth muscle. Glyceryl trinitrate produces a dose related dilation of both arterial and venous beds.

108
Q

Endone

A

is an opioid. It is used to relieve strong pain when other pain relievers such as paracetamol (for example Panadol®, Panamax®) and anti-inflammatories (for example Brufen®, Voltaren®) are not effective enough. Has the same mechanism of action as other opioids: binding to a receptor, inhibition of adenylyl-cyclase and hyperpolarisation of neurons, and decreased excitability

109
Q

metformin

A

mechanism of action: The centre of metformin’s mechanism of action is the alteration of the energy metabolism of the cell. Metformin exerts its prevailing, glucose-lowering effect by inhibiting hepatic gluconeogenesis and opposing the action of glucagon.
Used for: Metformin is used to control blood glucose (sugar) levels in people who have type 2 diabetes.

110
Q

Morphine Sulphate

A

Morphine is a full opioid agonist and is relatively selective for the mu-opioid receptor, although it can bind to other opioid receptors at higher doses. The principal therapeutic action of morphine is analgesia.

111
Q

Paracetamol

A

Paracetamol is a type of weaker analgesia for pain. It is thought to produce analgesia through a central inhibition of prostaglandin synthesis.

112
