Chapter 14 Drugs for the Reproductive System Questions
Question 1 of 5
The drug/drugs that can be used to treat osteoporosis is/are:
Correct Answer: D
Rationale: The correct answer is D because both Raloxifene (a selective estrogen receptor modulator) and Alendronate (a bisphosphonate) are commonly used to treat osteoporosis. Raloxifene helps prevent bone loss and reduces fracture risk, while Alendronate slows down bone breakdown. Pamidronate (choice C) is not typically used for osteoporosis treatment. Therefore, choices A, B, and C are incorrect.
Question 2 of 5
Bone resorption is accelerated by:
Correct Answer: B
Rationale: The correct answer is B: Parathormone. Parathormone stimulates osteoclast activity, which leads to increased bone resorption. Estrogens (choice A) actually inhibit bone resorption. Bisphosphonates (choice C) are used to decrease bone resorption. Calcitonin (choice D) also inhibits bone resorption by blocking osteoclast activity. Therefore, the correct choice is parathormone as it directly accelerates bone resorption by stimulating osteoclasts.
Question 3 of 5
Actions of oxytocin include the following except:
Correct Answer: A
Rationale: 1. Oxytocin is a hormone that primarily functions in inducing uterine contractions and milk let-down. 2. Vasoconstriction is not a known physiological action of oxytocin. 3. Increased water reabsorption, mammary contraction, and prostaglandin release are all effects of oxytocin. 4. Therefore, the correct answer is A: Vasoconstriction, as it is not a typical action of oxytocin.
Question 4 of 5
Concurrent use of the following drug is likely to cause failure of oral contraception:
Correct Answer: B
Rationale: The correct answer is B: Rifampicin. Rifampicin is an enzyme inducer that can accelerate the metabolism of oral contraceptives, leading to decreased effectiveness and potential contraceptive failure. It induces hepatic enzymes, increasing the metabolism of estrogen and progestin in oral contraceptives, reducing their efficacy. Isoniazid (A), Cimetidine (C), and Propranolol (D) do not have significant interactions with oral contraceptives.
Question 5 of 5
The most common and important undesirable effect of injectable contraceptive depot medroxyprogesterone acetate is:
Correct Answer: B
Rationale: The correct answer is B: Disruption of cyclic menstrual bleeding. Injectable contraceptive depot medroxyprogesterone acetate can cause irregular menstrual bleeding patterns, such as prolonged spotting or amenorrhea. This occurs due to the suppression of ovulation and the thinning of the endometrial lining. Nausea and vomiting (choice A) are less common side effects and usually subside after the initial injections. Venous thrombosis (choice C) and hypertension (choice D) are more associated with combined hormonal contraceptives containing estrogen.
