Correct Answer: B

Rationale: The correct answer is B: Bananas. Bananas are high in potassium, which should be limited in clients with chronic renal failure to prevent hyperkalemia. Apples (choice A), chicken (choice C), and rice (choice D) are not typically restricted in clients with chronic renal failure. Apples and rice are lower in potassium, while chicken is a good source of lean protein, which is usually encouraged in these clients to meet their protein needs without excess potassium intake.

Correct Answer: A

Rationale: A serum sodium level of 185 mEq/L (185 mmol/L) is dangerously high and indicates severe dehydration, requiring immediate intervention to prevent neurological damage. The other options are not as critical as high serum sodium levels, which can lead to serious complications such as seizures, coma, and death if not promptly addressed. Dry skin with poor skin turgor and polyuria with excessive thirst are common findings in clients with Diabetes Insipidus and should be managed but do not pose an immediate threat to the client's life. An apical heart rate of 110 beats per minute may indicate tachycardia, which could be related to dehydration but is not as urgent as addressing the severe hypernatremia.

Correct Answer: C

Rationale: The correct answer is 'Cold intolerance.' Hypothyroidism is associated with a decreased metabolic rate, leading to a decreased ability to regulate body temperature and a feeling of being cold. Fatigue (Choice A) and weight gain (Choice B) are also common symptoms of hypothyroidism due to the overall slowing down of bodily functions. Heat intolerance (Choice D) is more commonly associated with hyperthyroidism, where the body's metabolism is overactive, leading to increased heat production.

Correct Answer: A

Rationale: Following a transsphenoidal hypophysectomy, assessing the client for a cerebrospinal fluid (CSF) leak is crucial due to the risk of this serious complication. A CSF leak can lead to infection and increased intracranial pressure, which must be promptly identified and managed to prevent further complications. Fluctuating blood glucose levels (Choice B) are not directly associated with a transsphenoidal hypophysectomy. Cushing's syndrome (Choice C) is a condition related to prolonged exposure to high levels of cortisol and is not a common immediate concern post-transsphenoidal hypophysectomy. Cardiac arrhythmias (Choice D) are not typically a direct complication of this surgical procedure, making it a less relevant concern compared to a CSF leak.

Correct Answer: A

Rationale: During illness, individuals with type 1 diabetes mellitus may experience increased insulin requirements due to factors such as stress and the release of counterregulatory hormones. Increasing the frequency of self-monitoring, as stated in choice A, is crucial to closely monitor and adjust insulin doses as needed. Choice B, reducing food intake to alleviate nausea, is incorrect as it may lead to hypoglycemia and does not address the increased insulin needs during illness. Choice C, discontinuing the insulin dose if unable to eat, is dangerous as it can result in uncontrolled hyperglycemia. Choice D, taking the normal dose of insulin, may not be sufficient during illness when insulin requirements are likely elevated.
