While caring for a patient with an IABP at 3:1, the nurse notes:
A. decreasing urine output as well as increasing BUN and CR levels; the nurse should
increase timing to 2:1
B. absent pulses in the proximal extremity; the nurse should apply pressure at the
insertion site.
C. blood in the IABP tubing; the nurse should disconnect the balloon catheter from the
IABP.
D. blood oozing from the insertion site; the nurse should anticipate the need for an
emergency fasciotomy.
✓ A. incorrect. decreasing urine output with increasing BUN and CR levels with an
IABP in place indicates obstruction of the renal arteries. The nurse should plan
for removal.
✓ B. incorrect. absent pulses distal to the insertion site indicates complete
occlusion of the femoral artery. application of pressure to the insertion site will
worsen the obstruction.
✓ C. correct. blood in the IABP tubing indicates a rupture of the balloon.
Continuing to allow the IABP to inflate and deflate will increase the size of the
rupture, causing more bleeding. the nurse should plan for removal or exchange
of the IABP catheter.
✓ D. incorrect. a fasciotomy would be indicated if the patient had an increase in
fluid accumulation in the extremities causing significant injury to the limb.

An IABP is currently at 3:1 when the patient suddenly goes into ventricular fibrillation.
In addition to resuscitative measures, the nurse should:
A. change the trigger to internal or pressure support resuscitative measures.
B. increase timing back to 1:1 to increase coronary artery perfusion pressure.
C. put the pump on standby until the return of spontaneous circulation.
D. assess the IABP timing to chest compressions at 1:2.
✓ A. correct. the IABP will not be able to time correctly when a patient is in V-Fib.
by placing the system to trigger on internal or pressure support, it will generate
off the pressure created during compressions.
✓ B. incorrect. attempting to time the IABP back to 1:1 will be counterproductive,
as it will not be able to trigger correctly.
✓ C. incorrect. there is significant risk of clot forming on the IABP when placed in
stand for an indeterminate amount of time.
✓ D. incorrect. the primary goal during resuscitative measures is to attempt to
circulate blood volume as effectively as possible. assessing the timing of the
IABP is unnecessary.
The nurse is reviewing the home medications list for a patient admitted c/o severe
chest pain. serial EKGs and blood testing are negative, so an exercise stress test is
scheduled. which of the following medications may result in a false-positive finding on
the stress test?
A. digitalis (Digoxin)
B. potassium chloride (K-Dur)

, Top Mark Questions and Correct Verified Answers
C. sotalol (Betapace)
D. diltiazem (Cardiazem)
✓ A. correct. digitalis can cause false-positive EKG changes during a stress test.
there is an association between the development of ST segment depression
during stress testing. the mechanism of this EKG change is not clear. further,
digitalis should be withheld on the day of the test because of its negative
chronotropic effects.
✓ B. incorrect.
✓ C & D. incorrect. beta-blockers and calcium channel blockers blunt the heart rate
response to exercise and may prevent achievement of maximum predicted heart
rate. they should be withheld on the day of the test.
A patient is admitted with elevated troponin levels and ST segment elevation in leads
II, III, and aVF. Administration of which of the following should the nurse anticipate
initially?
A. enoxaparin (Lovenox)
B. streptokinase (Strepase)
C. alteplase (Activase)
D. reteplase (Retavase)

✓ A. incorrect. enoxaparin is an alternative to heparin in patients with unstable
angina, NSTEMI or DVT.
✓ B. incorrect. streptokinase is indicated for acute arterial thrombosis or
embolism, or occluded AV cannulas.
✓ C. incorrect. alteplase in indicated for acute ischemic stroke or acute massive
pulmonary embolism.
✓ D. correct. reteplase is indicated for AMI when fibrinolytics are indicated.
Which of the following is a characteristic of diastolic heart failure?
A. inability of the heart muscle to relax.
B. dilation of the ventricular chambers.
C. increased filling of the left ventricle.
D. decreased ability of the ventricle to contract.
