A nurse is performing cardiopulmonary resuscitation (CPR) for an adult client who is unresponsive. The nurse should evaluate the client's circulation by palpating which of the following pulses?
Radial
Carotid
Apical
Popliteal
The Correct Answer is B
Rationale:
A. The radial pulse is not as reliable as the carotid pulse in assessing circulation during CPR.
B. The carotid pulse is the most reliable site to assess circulation in an adult during CPR because it is closest to the heart and will reflect the true status of central circulation.
C. The apical pulse is not typically assessed during CPR due to its location and difficulty in palpation.
D. The popliteal pulse is not a recommended site for assessing circulation during CPR.

Correct Answer is D
Explanation
Rationale:
A. An electrophysiology study assesses the electrical activity of the heart but does not evaluate heart function or chamber size.
B. A 12-lead electrocardiogram records the electrical activity of the heart but does not provide detailed information on heart function or chamber size.
C. Cardiac catheterization is an invasive procedure used to assess coronary artery disease and other structural heart conditions but is not the primary study for evaluating heart function and chamber size.
D. An echocardiogram is a non-invasive ultrasound that provides detailed images of the heart, including its function, chamber size, and valve function, making it the best choice for this purpose.
Correct Answer is C
Explanation
Rationale:
A. Passive range of motion may be performed, but it is not the priority in this situation.
B. The head of the bed should be elevated 30 degrees or less, not necessarily flat, to prevent complications.
C. Hourly urinary output measurement is essential because the intra-aortic balloon pump (IABP) can impair renal perfusion, and monitoring urine output helps assess renal function.
D. Anticoagulants are often necessary to prevent clot formation associated with the IABP, so avoiding them is not advised unless contraindicated.
