Correct Answer: B

Rationale: Managerial skills are crucial for nurse managers to be effective. They need to possess skills such as problem-solving and decision-making to handle various challenges in the healthcare setting. Clinical knowledge (choice A) is important for direct patient care but may not be the primary focus of a manager's role. Patient care coordination (choice C) is vital, but managerial skills are more directly related to a nurse manager's effectiveness. Human resource training (choice D) is helpful but not as essential as managerial skills in ensuring effective leadership in a nursing environment.

Correct Answer: A

Rationale: The correct answer is A. The nurse's role in patient education involves providing patients with the necessary information to make informed decisions about their care. This includes explaining treatment options, potential risks and benefits, and answering any questions the patient may have. Choice B is incorrect because while nurses do educate patients and families, the primary focus is on empowering patients to make informed decisions. Choice C is incorrect as providing written materials is a part of patient education but not the sole responsibility of the nurse. Choice D is incorrect because while nurses do provide instructions on managing care at home, patient education goes beyond just the home care aspect to encompass a broader understanding of the patient's condition and treatment.

Correct Answer: A

Rationale: Polyuria (excessive urination) and polydipsia (excessive thirst) are classic clinical manifestations of diabetes insipidus. In this condition, there is a deficiency of antidiuretic hormone, leading to the inability of the kidneys to concentrate urine effectively, resulting in increased urine output (polyuria) and consequent thirst (polydipsia). Hypertension and bradycardia (Choice B) are not typical findings in diabetes insipidus. Weight gain and edema (Choice C) are more indicative of conditions such as heart failure or nephrotic syndrome. Oliguria (decreased urine output) and thirst (Choice D) are contradictory symptoms to what is seen in diabetes insipidus.

Correct Answer: D

Rationale: An adrenal adenoma is the most common cause of primary hyperaldosteronism. Hyperaldosteronism is typically caused by an adrenal adenoma, a benign tumor in the adrenal gland that leads to excessive aldosterone production. Excessive sodium intake (Choice A) does not directly cause hyperaldosteronism. Pituitary adenoma (Choice B) is associated with conditions like Cushing's disease, not hyperaldosteronism. Deficient potassium intake (Choice C) can lead to hypokalemia but is not a common cause of hyperaldosteronism.

Correct Answer: A

Rationale: The primary goal of nursing is to assist patients in achieving a peaceful death if recovery is not feasible. This involves providing comfort, dignity, and support during the end-of-life process. Choice B is incorrect because while improving personal knowledge and skills is important, it is not the primary goal of nursing. Choice C, advocating for quality of life over quantity of life, is a valid aspect of nursing care but may not always be the primary goal. Choice D, managing costs to enhance patients' quality of life, is not a primary goal of nursing, as the focus should primarily be on patient care and well-being, rather than financial considerations.
