HESI Leadership and Management

Correct Answer: A

Rationale: Exercising in the afternoon may coincide with the peak action of NPH insulin, increasing the risk of hypoglycemia. The peak action of NPH insulin typically occurs 4-12 hours after administration, so exercising during this time can further lower blood sugar levels. Choices B, C, and D are better options as they suggest exercising at times that are less likely to overlap with the peak insulin action, reducing the risk of hypoglycemia.

Correct Answer: A

Rationale: The correct answer is A: Tachycardia. In hypoglycemia, the body releases adrenaline in response to low blood glucose levels, leading to symptoms such as tachycardia (rapid heart rate). Choice B, polyuria, refers to excessive urination and is not a typical symptom of hypoglycemia. Choice C, flushed skin, is not a common symptom of hypoglycemia; instead, pale skin and sweating are more characteristic. Choice D, dry mouth, is not directly associated with hypoglycemia; rather, it can be a symptom of hyperglycemia or dehydration.

Correct Answer: C

Rationale: Increased urine osmolarity is the best assessment finding supporting a nursing diagnosis of Deficient fluid volume in a male client with hyperglycemia. In hyperglycemia, there is increased glucose in the blood, which leads to osmotic diuresis. This results in the excretion of large amounts of urine that is concentrated (high osmolarity), leading to dehydration and fluid volume deficit. Cool, clammy skin (Choice A) is more indicative of poor perfusion, distended neck veins (Choice B) are associated with fluid volume excess, and decreased serum sodium level (Choice D) could be a result of dilutional hyponatremia due to fluid overload rather than deficient fluid volume.

Correct Answer: B

Rationale: Postoperative hypotension is a common complication after adrenal tumor removal in a client with Cushing's syndrome. This occurs due to the sudden withdrawal of cortisol, which leads to a relative adrenal insufficiency state. Hyperglycemia (Choice A) is more common preoperatively due to excessive cortisol levels. Hypokalemia (Choice C) and Hyponatremia (Choice D) are also associated with Cushing's syndrome but are less likely to be immediate postoperative complications compared to hypotension.

Correct Answer: B

Rationale: When a client with hyperthyroidism undergoes radioactive iodine treatment, it often leads to hypothyroidism due to the destruction of thyroid tissue. This occurs as a desired outcome of the treatment to reduce the overactive thyroid function. Choices A, C, and D are incorrect. Increased heart rate, hypercalcemia, and weight loss are not expected side effects of radioactive iodine treatment for hyperthyroidism. Instead, the goal is to suppress the overactive thyroid, leading to a hypothyroid state.
