How do you calculate a mean arterial pressure (MAP)? - ANSWER SBP + 2(DBP) /3
What test is performed before inserting a radial arterial line? - ANSWER Allen's test
Allen's test (modified) - ANSWER The hand is elevated and the patient is asked to
clench their fist for about 30 seconds.
Ulnar and the radial arteries are occluded
Still elevated, the hand is then opened (it should appear blanched)
Ulnar pressure is released while radial pressure is maintained; color should return within 5
to 15 seconds.
How do you assess BP in patient with a ventricular assist device (VAD)? - ANSWER Via
arterial line
Ankle-brachial index (ABI) - ANSWER A ratio derived by dividing the ankle blood
pressure by the brachial blood pressure; this calculation is used to assess the vascular status
of the lower extremities. To obtain the ABI, a blood pressure cuff is applied to the lower
extremities just above the malleoli. The systolic pressure is measured by Doppler ultrasound
at both the dorsalis pedis and posterior tibial pulses. The higher of these two pressures is
then divided by the higher of the two brachial pulses.
What is a normal ankle-brachial index (ABI)? - ANSWER 1.0-1.4
What do you hear on percussion in air-leak syndrome? - ANSWER hyperresonance
1
,What ECG change do you see in carbon monoxide (CO) toxicity? - ANSWER sinus
tachycardia, ST depression
What is the difference between complete and incomplete cord syndromes? -
ANSWER Complete: no function below level of the injury
Incomplete: some function below level of the injury
Why do you use a barium enema in the treatment of intussusception? - ANSWER The
barium can push the intestine back into place in 90% of cases
In DKA, when is the insulin infusion discontinued? - ANSWER When the patient is
alert, oriented, eating and drinking normally, SC insulin can be resumed
Leave the IV insulin running for 30-60 min after first SC injection
What ECG change may you see in acute adrenal insufficiency? - ANSWER Peaked T
waves, widened QRS (due to hyperkalemia)
What is the purpose of permissive hypotension in pelvic fracture? - ANSWER To
prevent disruption of clot formation
What causes the dark urine in rhabdomyolysis? - ANSWER Myoglobin (muscle
breakdown product) secreted by the kidney
Why is creatine kinase (CK) elevated in rhabdomyolysis? - ANSWER CK is an enzyme
found in skeletal muscle; it is released as muscle tissue is damaged by rhabdo
What is a common complication seen in stage 2 of Lyme disease? - ANSWER neuro
complications (numbness, pain, weakness, Bell's palsy)
2
,How do you treat a patient with circumferential torso burn when you are unable to ventilate
with BVM? - ANSWER Sit patient up if appropriate
escharotomy
Why is pulse oximetry high during hypoxemia from carbon monoxide exposure? -
ANSWER Pulse oximetry does not differentiate between O2 and CO attached to
hemoglobin
Why does hydroxocobalamin in the Cyanokit turn urine red? - ANSWER It gives a
harmless and transient reddish colour to the skin and urine
Why is calcium required in hydrofluoric acid burn? - ANSWER Calcium gluconate binds
with the fluorine ion, preventing further penetration/damage of bone and tissue
Why is activated charcoal NOT effective in Iron ingestion? - ANSWER Activated
charcoal does not bind to iron
Which nursing ethical principle is EMTALA is based on? - ANSWER Justice? Can't find a
definitve answer to this anywhere!
Reporting suspected child maltreatment is practicing which ethical principle? -
ANSWER Nonmaleficence? Can't find a definitive answer to this anywhere!
How is JumpStart different from START disaster triage? - ANSWER The JumpSTART
pediatric triage MCI triage tool (usually shortened to JumpSTART) is a variation of the simple
triage and rapid treatment (START) triage system; JumpSTART was designed specifically for
triaging children in disaster settings
Body packers - ANSWER Whole bowel irrigation
3
, Deferoxamine - ANSWER Vin rose urine
Stimulants - ANSWER mydriasis

Digoxin - ANSWER yellow green vision
Beta blocker toxicity - ANSWER glucagon
acetaminiophen - ANSWER N-acetylcysteine
salicylates - ANSWER urine alkalination
sulfonylureas - ANSWER Octreotide
Phencyclidine (PCP) - ANSWER Combative behavior
Autonomy - ANSWER Right to make own health decisions & have their choices
respected
Beneficence - ANSWER Oath to help others - Including helping unresponsive pts
