Q

cause of tumor lysis syndrome

A

Tumor lysis syndrome is caused by the massive release of intracellular ions such as potassium, phosphorus, and nucleic acids that have been metabolized to uric acid. The main organ responsible for the excretions of these substances is the kidney.

** allopurinal = med to decrease uric acid levels

between 46-70 seconds (1.5-2.0x baseline)

protamine is reversal agent for heparin

38
Q

autonomic dysreflexia

A

occur in any individual with a spinal cord injury at or above T6

  • leads to exaggerated sympathetic nervous system response resulting in uncontrolled hypertension
  • common triggers include bladder or rectum distension and pressure ulcers

MANIFESTATIONS:
acute onset of throbbing h/a, nausea, blurred vision; hypertension and bradycardia; diaphoresis and skin flushing above level of injury

MED EMERGENCY –> need bladder cath to remove precipitating trigger

39
Q

GBS

A

acute immune-mediated polyneuropathy

  • ascending muscle paralysis
  • absence of reflexes
  • autonomic dysfunction is common (orthostatic hypotension, paralytic ileus, urinary retention, diaphoresis)
  • NM respiratory failure is the most life-threatening complication monitor rate and depth of resp

GOLD STANDARD FOR ASSESSING EARLY VENTILATION FAILURE: measurement of serial bedside forced vital capacity (spirometry)

40
Q

active pulmonary TB

A 
- airborne precaution (N95, hand hygiene)
clinical manifestations:
- cough
- night sweats
- fever 
- hemoptysis 
- unintended weight loss
- fatigue 
**negative pressure room**
41
Q

ectopic pregnancy

A

fertilized egg implants and begins to grow outside the uterine cavity
- may report a positive pregnancy test
- abdominal pain
vaginal spotting/bleeding
** can result in hemorrhage if left untreated and hemodynamic compromise**

42
Q

reaction to MMRV vax

A
  • within 5-12 days after 1st dose
  • low-grade fever, mild rash, swelling and erythema, irritability and restlessness
  • rare but fever after MMRV cax can lead to febrile seizures
43
Q

toxoplasmosis

A

parasitic infection… acquired from exposure to infected cat feces or ingestion of undercooked meat or soil contaminated fruits/veggies

can cause serious fetal harm

44
Q

SE of statins

A

hepatotoxicity
muscle aches

**assess LFT prior to starting med

45
Q

manifestations of airway obstruction

A

snoring
use of accessory muscles
decr o2 saturations
cyanosis

head tilt and chin lift is a maneuver used to open the airway

46
Q

risk factors of postpartum hemorrhage + extras

A

risk factors: grand multiparity (ie >/ 5 births), intrauterine infection, prolonged labor, use of oxytocin during labor, and coagulopathy

perineal pad that is saturated in 1 hour indicates heavy/excessive bleeding –> hemodynamic compromise

** assess fundal tone, lochia amount and VS and notify HCP IMMEDIATELY!**

47
Q

burn injuries

A

cause cellular destruction, capillary leaking and fluid shifts
fluids are lost during the emergent phase (first 24-72 hours), resulting in hypovolemia and hyponatremia… blood is more viscous and incr hematocrit and hemoglobin values

also releases potassium so hyperkalemia tall, peaked T waves, shortened QT interval and cardiac arrhythmias

48
Q

mature minors

A

adolescents 14-18, deemed able to understand treatment risks

allowed to give independent consent to receive/refuse treatment for some conditions (STIs, family planning, drug and alcohol abuse, blood donation and mental health care)

49
Q

mild-to-moderate dementia

A

may need frequent reality reorientation to promote appropriate behaviors

advanced dementia –> reality orientation may not be effective and might lead to anxiety, inappropriate behaviors and aggression, then use validation therapy

50
Q

cirrhosis

A

leads to elevated bilirubin, ammonia and coagulation studies (PT/INR and aPTT)

hyponatremia and hypoalbuminemia are expected

51
Q

polycythemia vera

A

requires periodic therapeutic phlebotomy treatments to reduce RBC count + risk of blood clotting associated with increased blood viscosity

** this can also occur secondary in someone w chronic hypoxemia (such as COPD) **
sluggish blood means decr tissue perfusion

52
Q

thrombocytopenic purpura

A

autoimmune condition in which antibodies bind to and cause destruction of platelets
increased risk for bleeding

  • *remember better to use electric razors, not safety razors**
    • low impact activity**
53
Q

somatic symptom disorder

A

psychological disorder that develops from stress –> medically unexplainable physical symtpoms

  • *redirect somatic complaints to unrelated, neutral topics
    • limit time spent discussing physical symptoms
    • secondary gains –> factors that intensify symptoms and coping strategies
54
Q

IV narcotics *pregnancy

A

nalbuphine, butorphanol, meperidine

give during the peak of contractions… can help decrease the sedation of the fetus and subsequent NB resp distress at birth

less med passes the placental barrier

55
Q

autonomic dysfunction + causes

A

dysfunction of the nerves that regulate nonvoluntary body functions, HR, BP and sweating *also affects BR, digestion, sensation

** can be sudden and severe but also reversible… typically irreversible

causes: uncontrolled diabetes, irregulat protein build up in organs (amyloidosis), autodimmune diseases, some meds (cancer drugs), viruses and bacteria (HIV, botulism, lyme) and some inherited disorders (hypothyrodism)
