BKAT ICU POST TEST EXAM
QUESTIONS AND ANSWERS. VERIFIED
2026.
Nitroprusside purpose - ANS decreases preload and afterload by vasodilation (mainly
afterload)
Dobutamine mechanism of action - ANS contractility
Dopamine at a low-end dose "renal dose" - ANS 0.5-4mcg/kg/min
increases renal and mesentric perfusion
Dopamine at a mid-range dose - ANS 4-10mcg/kg/min
increases contractility and heart rate
Dopamine at a high-range dose - ANS greater than 10mcg/kg/min
vasoconstriction and increases BP
Dopamine and Levophed infiltration - ANS leads to tissue necrosis

,Dopamine antidote - ANS regitine (phentolamine)
TpA monitor for - ANS bleeding-hemorrhagic CVA
diltiazem (cardizem) works by? - ANS (calcium channel blocker) slows ventricular rate by
slowing conduction through the SA and AV node
Diltazem (cardizem) biggest effect on which hemodynamic - ANS hypotension
diltazem is used for patients with - ANS a-fib or a-flutter
amiodarone (Cordarone) is a - ANS antiarrythmic
prolongs the cardiac duration
You MUST use a __________ when using amiodarone infusion - ANS 0.22 micron filter
Watch out for ____________ in patients on a amiodarone infusion - ANS hypotension,
prolongation of QT interval and bradycardia
amiodarone is used for patients with - ANS a-fib, a-flutter and VT
how much amiodarone is given to a stable VT with a pulse and a unstable pulseless VT/VF? -
ANS 150mg over 10min for VT with pulse
300mg push; repeat x1 at 150mg
Epinephrine has what effect on the body? - ANS increases HR, BP, and contractility
2 @COPYRIGHT 2025/2026 ALLRIGHTS RESERVED.
, what is the first line drug for pulseless arrest? - ANS Epinephrine
What rhythms are considered fatal? - ANS V-fib, Vtach (pulseless), and asystole
Epinephrine is also given for? - ANS anaphylaxis and as a vasopressor for hypotension
Heparin is used for? Antidote is? - ANS anticoagulant
Protamine Sulfate
What is the osmotic diuretic of choice to decrease intracranial pressure? - ANS mannitol
How does mannitol work? - ANS pulls fluids into intravascular space to be excreted by the
kidneys to reduce intracranial pressure
what insulin is given IV?
What is the peak? - ANS Regular insulin can only be given IV
2-4 hr peak time
Which insulin has a peak of 8-14 hrs? - ANS NPH
Atropine is ineffective in which heart rhythms types? - ANS high degree AV blocks: 2nd
degree type2 and 3rd degree
Atropine works by? - ANS increasing heart rate-increasing conduction through SA node
