Correct Answer: D

Rationale: The correct answer is D: An adrenal adenoma. Adrenal adenoma is the most common cause of primary hyperaldosteronism, also known as Conn's syndrome. Adrenal adenomas are benign tumors that cause overproduction of aldosterone, leading to increased sodium retention and potassium excretion. This results in hypertension and hypokalemia. Excessive sodium intake (A) and deficient potassium intake (B) are not direct causes of hyperaldosteronism. A pituitary adenoma (C) is associated with other hormone imbalances, such as Cushing's syndrome or acromegaly, but not hyperaldosteronism.

Correct Answer: D

Rationale: The correct answer is D because educating the client about the disease process and its limitations is crucial in managing Chronic Fatigue Syndrome (CFS). By understanding the disease, the client can make informed decisions regarding their lifestyle, activities, and self-care. This empowers the client to manage symptoms effectively and prevent exacerbations. Choice A is not the most important factor as simply avoiding aggravating the disease does not address the overall management of CFS. Choice B focuses solely on drug therapy, which is only one aspect of the client's management and may not provide significant improvement for all clients with CFS. Choice C, altering diet and environment, can be helpful but may not be the most important factor as understanding the disease process and limitations is essential for long-term management and quality of life.

Correct Answer: B

Rationale: The correct answer is B, notifying the health care provider. This is the most appropriate initial intervention because chest pain can be a symptom of a serious medical condition like a heart attack. The health care provider needs to be informed immediately to assess the situation and provide appropriate treatment. Reassessing the patient (A) may delay crucial medical intervention. Administering pain medication (C) without knowing the cause of chest pain can be dangerous. Calling radiology for a chest x-ray (D) is not the initial step in managing new onset chest pain.

Correct Answer: A

Rationale: Step-by-step rationale for why choice A is correct: 1. Enalapril maleate is an angiotensin-converting enzyme (ACE) inhibitor. 2. ACE inhibitors like enalapril maleate block the conversion of angiotensin I to angiotensin II. 3. By inhibiting the formation of angiotensin II, enalapril maleate decreases the levels of angiotensin II. 4. Angiotensin II is a potent vasoconstrictor, so decreasing its levels leads to vasodilation and decreased blood pressure. Summary of why other choices are incorrect: - Choice B: Enalapril maleate primarily dilates arterioles by decreasing angiotensin II levels, not veins. - Choice C: Enalapril maleate does not directly adjust extracellular volume; it primarily affects the renin-angiotensin-aldosterone system. - Choice D: Enalapril maleate

Correct Answer: A

Rationale: The correct answer is A: Fruits such as bananas. Bananas are high in potassium, which is essential for various bodily functions like muscle contractions and maintaining fluid balance. Fruits are a natural source of potassium and are easily incorporated into the diet. Milk and yogurt (B) are good sources of calcium, not potassium. Green leafy vegetables (C) are nutritious but may not provide as much potassium as fruits. Nuts and legumes (D) are good sources of protein and healthy fats but are not as rich in potassium as fruits like bananas.
