Which condition or factor would be the LEAST likely to result in a change in behavior?

• A. Fever
• B. Sleep deprivation
• C. Anxiety
• D. Antihypertensive medications

Answer: (D)

Behavioral changes come from factors that directly affect brain function and arousal. Fever can cause delirium or confusion, especially in older adults, so it often changes how a person behaves. Sleep deprivation impairs judgment, mood, and reaction time, leading to noticeable changes in behavior. Anxiety increases physiologic arousal and can produce restlessness and agitation, also altering behavior. Antihypertensive medications, on the other hand, primarily affect the cardiovascular system; while they can cause dizziness or fatigue, they don’t typically produce a direct change in behavior. Therefore, antihypertensive medications are least likely to result in a change in behavior.
