The appropriate emergency treatment of this patient should include which of the following drugs?

Correct Answer: D

Rationale: The correct answer is D: Prednisone. Prednisone is a corticosteroid that helps reduce inflammation and suppress the immune system. In an emergency situation, such as an acute asthma attack or anaphylactic reaction, prednisone can quickly alleviate symptoms and prevent further complications. Fludrocortisone (A) is a mineralocorticoid mainly used for adrenal insufficiency, not for emergency treatment. Azathioprine (B) is an immunosuppressant used for organ transplant recipients or autoimmune diseases, not for acute emergencies. Norethindrone (C) is a progestin hormone used for contraception or hormone replacement therapy, not for emergency treatment.

Correct Answer: B

Rationale: The correct answer is B: Ethinyl estradiol and norethindrone. This combination is a safer choice for the woman due to her history of disseminated intravascular coagulation following an abortion. Ethinyl estradiol and norethindrone have a lower risk of venous thromboembolism compared to other estrogen-containing contraceptives, making it a suitable option for this patient. Rationale for other choices: A: Diethylstilbestrol is contraindicated due to its association with an increased risk of thromboembolic events. C: Mestranol and norethindrone combination may also increase the risk of thromboembolic events, making it unsuitable for this patient. D: Mifepristone is not a hormonal contraceptive; it is used for medical abortion and emergency contraception, not for regular contraception.

Correct Answer: C

Rationale: The correct answer is C: Norgestrel. Nausea is a common side effect of contraceptive pills, especially when initially starting them. Norgestrel is a component of the contraceptive pill the patient started one week ago, which aligns with the timing of the onset of her nausea symptoms. Ciprofloxacin and omeprazole are less likely to cause nausea in this case, as the patient has been taking them for some time without issues. Ethinyl estradiol is also a component of the contraceptive pill but is less likely to be the primary cause of the nausea compared to norgestrel.

Correct Answer: C

Rationale: The correct answer is C: Add calcitonin to the current regimen. Calcitonin helps to increase bone density and reduce bone loss in osteoporosis. This would address the significant decrease in bone mass. Choice A (substitute hydrochlorothiazide with propranolol) is incorrect as propranolol does not have a direct impact on bone mass. Choice B (substitute raloxifene with ethinyl estradiol) is incorrect as ethinyl estradiol is not typically used for osteoporosis and may not be effective. Choice D (increase the daily dose of calcium carbonate) is incorrect as simply increasing calcium intake may not be sufficient to address the bone loss, especially in the presence of inadequate bone formation. Adding calcitonin addresses the root cause of bone loss in osteoporosis and is therefore the appropriate change in the treatment plan.
