A nurse performing an assessment would correctly note that an absent pulse in one or more of the extremities indicates

Decreased plasma volume.

Problems with the heart's electrical conduction system.

Shock.

A blockage of blood flow.

Answer and Explanation

The Correct Answer is D

A.   Decreased plasma volume might cause overall weak pulses but would unlikely cause an absent pulse specifically localized in one or more extremities. Decreased plasma volume generally affects circulation systemically, not selectively in certain limbs.
B.   Problems with the heart's electrical conduction system primarily affect the rhythm and rate of the heart but do not directly cause absent pulses in extremities. These issues lead to irregular or abnormal heartbeats, not localized absence of pulses.
C.   Shock can result in weak or thready pulses due to poor blood flow, but shock alone would not typically cause a pulse to be completely absent in one extremity while present in others. Shock affects the circulatory system as a whole.

D.   A blockage of blood flow is the most likely cause of an absent pulse in one or more extremities. This could be due to atherosclerosis, embolism, or thrombosis, which can obstruct blood flow in specific areas, leading to no detectable pulse in those extremities.
