Endocrine Pharmacology Quizlet Questions
Question 1 of 5
A 21-year-old woman plans to spend a semester high in the Andes. She shares a concern with her doctor about the elevation because 1 year ago, she went on a ski trip to Colorado and developed altitude sickness. Her doctor prescribes a diuretic that can help her if she begins to have symptoms of altitude sickness. Which diuretic did her doctor likely prescribe?
Correct Answer: A
Rationale: Acetazolamide, a carbonic anhydrase inhibitor, prevents altitude sickness by inducing metabolic acidosis, stimulating ventilation, and improving oxygenation.
Question 2 of 5
A 56-year-old male with insulin-dependent diabetes and with poorly controlled blood sugar is on regular insulin. His primary care physician adds pramlintide in an effort to further reduce his blood sugar levels. An important condition to rule out in this patient would be which of the following?
Correct Answer: A
Rationale: Pramlintide slows gastric emptying; pre-existing gastric retention (e.g., gastroparesis) must be ruled out to avoid exacerbating GI issues.
Question 3 of 5
A 56-year-old man with Type-2 diabetes mellitus managed with acarbose presents to his primary care physician for a follow-up evaluation. His most recent laboratory studies indicate normal serum glucose levels and low serum amylase. What is the most likely explanation for this finding?
Correct Answer: B
Rationale: Acarbose inhibits intestinal alpha-glucosidase, not pancreatic amylase directly, but reduced carbohydrate breakdown may lower serum amylase demand, a benign finding here.
Question 4 of 5
A 22-year-old woman is using a vaginal ring as a contraceptive agent. She has no other medical problems. She is concerned about device failure and becoming pregnant. What is the most likely reason for this failure to occur?
Correct Answer: D
Rationale: Slippage of the vaginal ring can lead to inadequate hormone delivery (ethinyl estradiol and etonogestrel), increasing the risk of contraceptive failure.
Question 5 of 5
An 18-year-old male high school baseball player is interested in improving his hitting ability. He receives twice weekly injections of anabolic steroids. Over the next year, which of the following effects would be likely observed in this patient?
Correct Answer: C
Rationale: Anabolic steroids accelerate epiphyseal closure in adolescents, stunting long bone growth due to excess androgen activity.
