Endocrine Pharmacology Quizlet Questions
Question 1 of 5
Which of the following drugs would be most appropriate for postcoital contraception in this patient?
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.
Question 2 of 5
Which of the following actions most likely mediated the therapeutic efficacy of calcitriol in a patient with diffuse demineralization of bone?
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.
Question 3 of 5
Which of the following drugs would be appropriate to include in the therapeutic management of this patient?
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.
