ATI Endocrine Pharmacology Quizlet Questions
Question 1 of 5
Which of the following drugs most likely caused these results?
Correct Answer: C
Rationale: The correct answer is C: Methimazole. Methimazole is an antithyroid drug used to treat hyperthyroidism by inhibiting thyroid hormone synthesis. The results described are likely due to hyperthyroidism, which methimazole would help regulate. Radioactive iodine (A) is used to destroy thyroid tissue, potassium iodide (B) is used to protect the thyroid from radiation, and propranolol (D) is a beta-blocker used to manage symptoms but does not directly address thyroid hormone levels.
Question 2 of 5
Which of the following drugs most likely caused the patient's signs and symptoms?
Correct Answer: A
Rationale: The correct answer is A: Prednisone. Prednisone is a corticosteroid that can cause signs and symptoms such as weight gain, fluid retention, and mood changes, which align with the patient's presentation. Mesalamine (B) is used to treat inflammatory bowel disease and does not typically cause these symptoms. Loperamide (C) is an anti-diarrheal agent and would not explain the patient's signs. Azathioprine (D) is an immunosuppressant used in inflammatory conditions but is less likely to cause the specific signs and symptoms described.
Question 3 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 4 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 5 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.
