LPN Pharmacology

Correct Answer: B

Rationale: When a client with CAD experiences chest pain, it indicates myocardial ischemia. The nurse should have the client stop the activity and lie back down in bed to reduce the heart's oxygen demand, decrease myocardial workload, and prevent further ischemia. This action helps in improving blood flow to the heart and can potentially alleviate the chest pain.

Correct Answer: B

Rationale: Increasing sodium intake is essential when taking lithium to counteract the risk of developing hyponatremia. Lithium can lead to decreased sodium levels, so increasing sodium intake can help maintain an adequate balance and prevent complications.

Correct Answer: B

Rationale: Adhering to dietary restrictions is crucial in managing heart health post-angioplasty.

Correct Answer: A

Rationale: Caffeine should be avoided before a dipyridamole thallium scan as it can interfere with the test results. Caffeine is a stimulant that can affect the heart rate and may lead to inaccurate findings during the scan. Therefore, it is essential for the LPN/LVN to check and ensure that the client has not consumed caffeine prior to the procedure to obtain accurate diagnostic results.

Correct Answer: B

Rationale: Choosing a diet that is low in fat and cholesterol is crucial for managing and preventing the progression of coronary artery disease (CAD). This dietary change can help reduce the risk of further complications associated with CAD, such as plaque buildup in the arteries. It is a fundamental lifestyle alteration that can positively impact the client's heart health.
