Question

An older adult comes to the emergency department after taking cimetidine (Tagamet). It is most important for the nurse to monitor the patient for which effect?

a) Confusion
b) Hypoglycemia
c) Tachycardia
d) Akinesia

Answer 1

The most important effect to monitor in an older adult who has taken cimetidine (Tagamet) is confusion, due to the drug's ability to cross the blood-brain barrier and cause central nervous system side effects.

Step-by-step explanation:

When an older adult presents to the emergency department after taking cimetidine (Tagamet), it is most important for the nurse to monitor the patient for confusion. Cimetidine is a medication that can cross the blood-brain barrier and in older adults, especially those with preexisting conditions or reduced renal clearance, it can cause central nervous system side effects such as confusion or delirium. Cognitive effects like confusion are of particular concern in the elderly given their potential complications and the impact on patient safety.
