LPN Pharmacology

Correct Answer: D

Rationale: Lemonade is the correct choice as it is caffeine-free, unlike tea, cola, and coffee, which contain caffeine that can potentially affect the client's heart rhythm. Caffeine can increase heart rate and blood pressure, which may not be advisable for a client with a recent MI.

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: Wearing comfortable shoes and clothing is crucial for the client undergoing a treadmill stress test to ensure they can complete the test without discomfort. The right attire will help the client move freely and reduce the risk of any hindrance during the test, which requires physical activity.

Correct Answer: C

Rationale: Option C, which includes baked haddock, steamed broccoli, herbed rice, and sliced strawberries, is the most appropriate choice for a client with myocardial infarction looking to reduce saturated fat and cholesterol intake. This meal is low in saturated fats and cholesterol, making it a heart-healthy option that aligns with the dietary recommendations for such clients.

Correct Answer: C

Rationale: The correct answer is C. Using polyunsaturated oils, such as vegetable oils, can help manage cholesterol levels and reduce the risk of heart disease. This dietary change is beneficial for individuals with coronary artery disease as it promotes heart health by improving cholesterol profiles. Substituting eggs and milk for meat (Choice A) may not address the overall dietary needs for managing the condition. Completely eliminating all cholesterol and fat from the diet (Choice B) is not necessary as the body needs some healthy fats. Considering becoming a strict vegetarian (Choice D) is a personal choice and may not necessarily be required to manage coronary artery disease.
