Question 1 of 5
A nurse is preparing to administer atropine to a patient with symptomatic bradycardia. Which of the following is the primary therapeutic effect of atropine in this scenario?
Correct Answer: C
Rationale: The correct answer is C: Increase in heart rate. Atropine is a muscarinic antagonist that blocks the parasympathetic nervous system, leading to an increase in heart rate. This effect helps in treating bradycardia by stimulating the heart to beat faster. Vasodilation (
A) and bronchodilation (
B) are not the primary effects of atropine in this scenario. Diuresis (
D) is not a direct effect of atropine on the heart rate.
Therefore, the correct choice is C as it directly addresses the bradycardic condition by increasing the heart rate.
