LPN Pharmacology

Correct Answer: B

Rationale: After being transferred from the CCU to the general medical unit with cardiac monitoring, the client with MI is typically prescribed bathroom privileges and self-care activities. This allows for gradual recovery and mobility while still being closely monitored, promoting the client's overall well-being and independence.

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.

Correct Answer: A

Rationale: Clients with rheumatic heart disease are at risk for infective endocarditis, a serious infection of the heart lining or valves, and need prophylactic antibiotics before invasive procedures, including dental work, to prevent this life-threatening complication.

Correct Answer: A

Rationale: In hyperkalemia, tall, peaked T waves are a distinct ECG finding. These T waves can be seen as a result of increased serum potassium levels, affecting the repolarization phase of the cardiac action potential. It is crucial for healthcare providers to recognize this ECG change promptly as hyperkalemia can lead to serious cardiac arrhythmias and complications.

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.
