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 B
Explanation
Rationale:
A. While lowering BP to 120/80 may be an ultimate goal, it is not the initial target in a hypertensive emergency.
B. Rapid reduction in blood pressure can cause hypoperfusion of vital organs such as the brain, heart, and kidneys, leading to ischemic injury. The aim is to reduce the BP gradually to prevent these complications.
C. IV antihypertensive medications generally have a rapid onset, not a slow one.
D. While gradual reduction is important, it is not done to allow rest but to protect organ perfusion.
Correct Answer is B
Explanation
Rationale:
A. Epinephrine is an important drug in resuscitation but is administered after defibrillation in the algorithm.
B. Defibrillation is the priority intervention for ventricular fibrillation, as it is the only treatment that can convert the heart rhythm back to a viable one.
C. Airway management is crucial, but in the context of ventricular fibrillation, defibrillation takes precedence to restore a life-sustaining rhythm.
D. Amiodarone is used in the treatment of refractory ventricular fibrillation, but it is not the immediate priority over defibrillation.
