The nurse is caring for a client with primary adrenal insufficiency (Addison's disease). Which of the following laboratory findings would the nurse expect?

Correct Answer: B

Rationale: In primary adrenal insufficiency (Addison's disease), there is a decrease in aldosterone levels, leading to sodium loss and potassium retention. This imbalance results in hyperkalemia, making choice B the correct answer. Hypernatremia (choice A) is unlikely due to sodium loss. Hyperglycemia (choice C) and hypercalcemia (choice D) are not typically associated with primary adrenal insufficiency.

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.

Correct Answer: A

Rationale: Clients with Cushing's syndrome are at risk for hyperglycemia due to the effects of cortisol on glucose metabolism. Monitoring blood glucose levels is crucial to detect and manage hyperglycemia promptly. Restricting fluid intake (choice B) is not necessary unless specifically indicated for another condition, as clients with Cushing's syndrome are prone to fluid imbalances. Administering potassium supplements (choice C) is not appropriate as clients with Cushing's syndrome often have elevated potassium levels due to the effects of cortisol. Encouraging a high-protein diet (choice D) is not recommended as clients with Cushing's syndrome should focus on a balanced diet to manage their condition effectively.

Correct Answer: C

Rationale: The correct instruction for a client with type 2 diabetes mellitus regarding foot care is to inspect their feet daily for any cuts or sores. This practice helps in early detection of potential issues like cuts, sores, or infections, which can be challenging to heal due to poor circulation in diabetes. Choice A is incorrect because soaking feet in hot water can lead to burns or skin damage, especially for individuals with diabetes who may have reduced sensation. Choice B is incorrect because going barefoot increases the risk of injuries and infections for individuals with diabetes. Choice D is incorrect because using a heating pad can also impair sensation, increasing the risk of burns or injuries for diabetic individuals.

Correct Answer: A

Rationale: The correct answer is A, lactic acidosis. Metformin, a common medication for type 2 diabetes mellitus, can lead to lactic acidosis, particularly in individuals with renal impairment or predisposing factors. Monitoring for signs of lactic acidosis, such as muscle pain, weakness, trouble breathing, dizziness, and slow or uneven heart rate, is crucial to prevent serious complications. Choices B, C, and D are incorrect as metformin does not typically cause hypokalemia, hyperglycemia, or weight gain as its primary side effects.
