Cardiovascular System Exam Questions And Answers Questions
Question 1 of 5
What is the primary effect of a calcium channel blocker on the heart?
Correct Answer: D
Rationale: The primary effect of a calcium channel blocker on the heart is to decrease blood pressure. Calcium channel blockers block the entry of calcium into the smooth muscle cells of blood vessels and the heart. This causes vasodilation and reduces the force of contraction in the heart, leading to a decrease in blood pressure. Choices A and B are incorrect as calcium channel blockers typically do not directly affect heart rate. Choice C is incorrect because calcium channel blockers actually tend to lower blood pressure rather than increase it.
Question 2 of 5
The nurse is caring for a client on amiodarone who complains of visual disturbances. What is the nurse's best response?
Correct Answer: A
Rationale: The correct answer is A: Notify the healthcare provider immediately. Visual disturbances can be a sign of serious side effects of amiodarone, such as optic neuropathy. Promptly notifying the healthcare provider allows for timely evaluation and appropriate management. Choice B is incorrect because visual disturbances with amiodarone are not common and should not be dismissed as such. Choice C is incorrect as self-monitoring may delay necessary medical intervention. Choice D is also incorrect as reducing physical activity does not address the underlying cause of visual disturbances and may not be necessary.
