Question 1 of 5
When a patient is taking an adrenergic agonist drug, the nurse expects to observe which effect?
Correct Answer: C
Rationale: The correct answer is C: Increased heart rate. Adrenergic agonist drugs stimulate the sympathetic nervous system, leading to increased heart rate through the activation of beta-adrenergic receptors on the heart. This results in a positive chronotropic effect.
Choices A, B, and D are incorrect because adrenergic agonists do not directly affect intestinal peristalsis, bronchial constriction, or pupil constriction. Adrenergic agonists typically have the opposite effect on these functions (e.g., increased bronchodilation and pupil dilation).
