Correct Answer: A

Rationale: The correct answer is A: Serum glucose level. In Cushing's syndrome, there is excess cortisol production which can lead to hyperglycemia. Successful treatment of Cushing's syndrome aims to normalize cortisol levels, resulting in a decline in serum glucose levels. Choice B, hair loss, is not specifically associated with Cushing's syndrome or its treatment. Choice C, bone mineralization, is often compromised in Cushing's syndrome due to the effects of excess cortisol on bones; however, successful treatment would aim to improve bone health rather than decline it. Choice D, menstrual flow, is not directly linked to Cushing's syndrome or its treatment, so a decline in menstrual flow would not be an expected outcome of successful treatment.

Correct Answer: B

Rationale: The first action should be to discontinue the intravenous line to prevent further complications such as infection or thrombophlebitis. Starting a new IV in the right hand is not the priority as addressing the current issue is important. Completing an incident record can be done after addressing the immediate concern of the IV site. Placing a warm washcloth over the site does not address the red streak and tenderness, which may indicate an infection that requires discontinuation of the IV line.

Correct Answer: B

Rationale: Puffiness of the face and hands is a classic symptom of hypothyroidism. This occurs due to fluid retention and is commonly observed in individuals with an underactive thyroid gland. Increased appetite and weight loss (Choice A) are more indicative of hyperthyroidism, where there is an overproduction of thyroid hormones leading to increased metabolism. Nervousness and tremors (Choice C) are associated with hyperthyroidism, not hypothyroidism. Thyroid gland swelling (Choice D) typically indicates goiter, which can be present in both hyperthyroidism and hypothyroidism but is not a specific symptom that clients with hypothyroidism commonly report.

Correct Answer: C

Rationale: In hyperparathyroidism, there is excessive production of parathyroid hormone, leading to increased calcium resorption from the bones. This process causes bone pain, making choice C the correct answer. Tetany (choice A) is associated with hypocalcemia, not hyperparathyroidism. Hypocalcemia (choice B) is the opposite condition of hyperparathyroidism, where blood calcium levels are elevated. Hypotension (choice D) is not a typical symptom of hyperparathyroidism.

Correct Answer: A

Rationale: The correct answer is A: Oral anticoagulants. Glucagon may enhance the anticoagulant effect of oral anticoagulants, increasing the risk of bleeding. This interaction can be dangerous for the patient, leading to serious complications. Choices B, C, and D are incorrect because anabolic steroids, beta-adrenergic blockers, and thiazide diuretics do not typically interact adversely with glucagon. It is crucial for healthcare providers to be aware of potential drug interactions to ensure patient safety and optimal outcomes.
