Question 1 of 5
What are the effects that could occur as a result of an excessive dose of methimazole in a patient with Graves disease?
Correct Answer: B
Rationale: The correct answer is B: Sweating. Excessive dose of methimazole, an anti-thyroid medication used to treat Graves disease, can lead to increased sympathetic nervous system activity, causing hyperactivity of sweat glands and resulting in sweating. Palpitations (A) are more commonly associated with hyperthyroidism itself, rather than medication side effects. Insomnia (C) can be a symptom of hyperthyroidism but is not a direct effect of methimazole overdose. Tremor (D) is also a common symptom of hyperthyroidism, not a specific effect of methimazole overdose.
Question 2 of 5
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.
Question 3 of 5
Which of the following drugs would be appropriate for local therapy in this patient?
Correct Answer: B
Rationale: The correct answer is B: Norgestrel. Norgestrel is a progestin used for local therapy in this patient because it can be administered directly to the affected area to target specific tissues. Ethinyl estradiol, Anastrozole, and Tamoxifen are not appropriate for local therapy as they are systemic drugs that act throughout the body. Ethinyl estradiol is an estrogen component in combined oral contraceptives, Anastrozole is an aromatase inhibitor used for breast cancer systemically, and Tamoxifen is a selective estrogen receptor modulator used for breast cancer treatment.
Question 4 of 5
A 26-year-old woman asked her family physician for a hormonal contraceptive. She refused other methods of contraception. Past history of the woman indicated disseminated intravascular coagulation that followed an abortion due to placental abruptio. Which of the following would be the most appropriate hormonal contraceptive preparation for this woman?
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.
Question 5 of 5
A 21-year-old woman complained to her physician of recurrent nausea lasting most of the day. The woman had been suffering from a urinary tract infection presently being treated with ciprofloxacin and from gastroesophageal reflux disease presently being treated with omeprazole. She also routinely took ibuprofen during her menstrual period. One week ago, she started taking a contraceptive pill (ethinyl estradiol and norgestrel). Which of the following drugs most likely caused the patient's nausea?
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.
