Questions With Correct Answers
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. - answer✔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. - answer✔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)
C. sotalol (Betapace)
D. diltiazem (Cardiazem) - answer✔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) - answer✔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. - answer✔A. correct. with diastolic heart failure
the left ventricle is unable to relax, leading to signs and symptoms of heart failure, but the patient
maintains a preserved EF as the muscle retains its ability to contract.
B. incorrect. dilation of the ventricular chambers is a characteristic of systolic heart failure.
C. incorrect. diastolic heart failure is an abnormality with heart filling. the heart muscle does not
relax normally, and the heart may fill too slowly or asynchronously. if the left ventricle does not
relax properly or is thick and stiff, it does not fill in the usual manner and blood is drawn back
into the left atrium and eventually into the lungs.
