Which of the following was most likely the primary goal for restarting prednisone treatment in this patient?

Correct Answer: C

Rationale: The correct answer is C: To avoid opportunistic infections after surgery. Prednisone is a corticosteroid that suppresses the immune system, which can increase the risk of infections. Restarting prednisone post-surgery may be necessary to prevent opportunistic infections due to the patient's suppressed immune response. Choices A, B, and D are incorrect because adrenal insufficiency, wound healing, and gallbladder relaxation are not typically primary goals for restarting prednisone treatment in this context.

Correct Answer: C

Rationale: The correct answer is C: Levonorgestrel. Levonorgestrel is a progestin commonly used for emergency contraception due to its effectiveness in preventing pregnancy when taken shortly after unprotected intercourse. It works by inhibiting ovulation and fertilization. Clomiphene (A) is used to induce ovulation, not for emergency contraception. Leuprolide (B) is a gonadotropin-releasing hormone agonist used for conditions like endometriosis or prostate cancer, not for emergency contraception. Fulvestrant (D) is a selective estrogen receptor degrader used in breast cancer treatment, not for emergency contraception.

Correct Answer: A

Rationale: The correct answer is A because testosterone therapy for adult-onset hypogonadism typically suppresses the hypothalamic-pituitary-gonadal axis, leading to reduced LH secretion. This is due to negative feedback inhibition by the exogenous testosterone. Enhanced LH secretion is not expected. Choices B, C, and D are incorrect as testosterone therapy does not directly impact clotting factors synthesis, bone marrow stem cell growth, or erythropoietin synthesis.

Correct Answer: D

Rationale: The correct answer is D because calcitriol, the active form of vitamin D, increases intestinal calcium absorption by enhancing the expression of calcium-binding proteins and transporters. This helps in the treatment of diffuse demineralization of bone by ensuring an adequate supply of calcium for bone mineralization. Stimulation of liver hydroxylation of cholecalciferol (choice A) and renal α hydroxylase (choice B) are not directly related to the therapeutic efficacy of calcitriol. Decreased intestinal phosphate absorption (choice C) would not address the demineralization of bone because phosphate is not the primary mineral component of bone.

Correct Answer: A

Rationale: The correct answer is A: Calcitriol. This patient likely has a calcium deficiency, as calcitriol is the active form of vitamin D that helps regulate calcium levels in the body. It would be appropriate for managing this condition. B: Hydrochlorothiazide is a diuretic used to treat high blood pressure and edema, not calcium deficiency. C: Sodium fluoride is used to prevent tooth decay, not for treating calcium deficiency. D: Triamterene is a diuretic that works by increasing potassium excretion, not relevant for treating a calcium deficiency.
