Correct Answer: C

Rationale: Tachycardia is a potential adverse effect of levothyroxine, indicating overmedication. Dysuria (painful urination) is not typically associated with levothyroxine. Leg cramps are not a common adverse effect of levothyroxine. Blurred vision is not a typical adverse effect of levothyroxine; instead, it may be a sign of other eye-related conditions or medication side effects.

Correct Answer: A

Rationale: When a client experiences secondary failure to an oral antidiabetic agent like glipizide, the next step is often to initiate insulin therapy. This is because secondary failure indicates that the current oral antidiabetic medication is no longer effective in managing blood glucose levels, and insulin therapy may be required to adequately control blood sugar. Switching to a different oral antidiabetic agent may not be effective if there is already resistance to the current agent. Adding another oral antidiabetic agent may not address the underlying issue of secondary failure. Restricting carbohydrate intake is important for diabetes management but is not the primary intervention indicated in this scenario of secondary failure to glipizide.

Correct Answer: A

Rationale: For clients with hypoparathyroidism, the appropriate dietary recommendation is to increase intake of calcium-rich foods like dairy products and green leafy vegetables to help manage hypocalcemia. This is because hypoparathyroidism leads to low levels of calcium in the blood, so increasing calcium intake through diet is essential.

Choices B, C, and D are incorrect. Avoiding foods high in calcium (choice
B) would exacerbate the hypocalcemia. Consuming a high-sodium diet (choice
C) is not necessary for managing hypoparathyroidism. Limiting fluid intake (choice
D) is not directly related to the dietary management of hypoparathyroidism.

Correct Answer: B

Rationale: During an Addisonian crisis, the adrenal glands are not producing enough cortisol, leading to a life-threatening situation. Hydrocortisone, a glucocorticoid, is the medication of choice in managing an Addisonian crisis. It helps replace deficient cortisol levels, stabilize blood pressure, and prevent further complications. Insulin (
Choice
A) is not indicated in Addison's disease unless specifically needed for diabetes management. Levothyroxine (
Choice
C) is used in hypothyroidism, not in Addison's disease. Methimazole (
Choice
D) is used to manage hyperthyroidism, which is not related to Addison's disease or its crisis.

Correct Answer: C

Rationale: In an Addisonian crisis, there is a lack of adrenal hormones leading to severe hypotension. Hypertension (choice
A) is not a typical sign of Addisonian crisis but can occur in conditions like pheochromocytoma. Hyperglycemia (choice
B) is not a characteristic sign of an Addisonian crisis. Tachycardia (choice
D) may occur as a compensatory mechanism in response to hypotension, but severe bradycardia is more common in an Addisonian crisis.
