Correct Answer: A

Rationale: The correct answer is A. Effective communication is essential for ensuring that all staff members are informed, understand their roles, and can collaborate effectively to provide quality care. Choice B focuses more on information sharing and understanding roles but lacks emphasis on effective teamwork and quality care provision. Choice C mentions staff working together effectively and understanding unit goals, but it does not explicitly highlight the importance of staff being informed and understanding their roles. Choice D emphasizes creating an open environment for sharing information and concerns, which is important but does not encompass the broader aspects of effective communication as described in choice A.

Correct Answer: B

Rationale: Myxedema coma is a severe, life-threatening complication that can occur in individuals with untreated or inadequately treated hypothyroidism. It is characterized by extreme hypothyroidism leading to decreased mental status, hypothermia, bradycardia, and respiratory depression. Thyroid storm (Choice A) is a severe complication of hyperthyroidism, not hypothyroidism. Cushing's syndrome (Choice C) results from prolonged exposure to high levels of cortisol, not related to hypothyroidism. Diabetic ketoacidosis (Choice D) is a complication of uncontrolled diabetes, not directly associated with hypothyroidism.

Correct Answer: A

Rationale: Bradycardia in a client with hypothyroidism is the most concerning finding as it may indicate severe hypothyroidism, leading to decreased heart rate. Bradycardia can be a sign of myxedema coma, a life-threatening condition that requires immediate medical attention. Dry skin, constipation, and depression are common symptoms associated with hypothyroidism but are not as acutely concerning as bradycardia.

Correct Answer: A

Rationale: In hyperaldosteronism, there is an excess of aldosterone production, leading to increased sodium retention and potassium excretion by the kidneys. This results in hypokalemia (low potassium levels). Therefore, the correct answer is hypokalemia (Choice A). Hypernatremia (Choice B) is an incorrect choice as hyperaldosteronism primarily affects potassium and not sodium levels. Hyperkalemia (Choice C) is also incorrect because hyperaldosteronism causes potassium excretion, leading to low levels. Hypocalcemia (Choice D) is not typically associated with hyperaldosteronism; instead, it is more related to conditions affecting calcium regulation.

Correct Answer: B

Rationale: Diaphoresis is the correct answer because it is more characteristic of hypoglycemia. Hypoglycemia typically presents with symptoms such as diaphoresis (excessive sweating), palpitations, tremors, and anxiety. On the other hand, ketoacidosis is associated with symptoms such as fruity breath, deep and labored breathing (Kussmaul respirations), nausea, vomiting, and abdominal pain. Blurred vision can occur in both hypoglycemia and ketoacidosis due to metabolic disturbances affecting the eyes. Weakness is a nonspecific symptom that can be present in both conditions, making it less helpful in distinguishing between the two.
