Endocrine Pharmacology Quizlet Questions
Question 1 of 5
A 57-year-old man with a 40 pack-year history of smoking develops small cell lung cancer. His serum sodium is 121mEq\L and his urine has a specific gravity of 1.030 . Which of the following is a tetracycline antibiotic that can also be used in the treatment of SIADH?
Correct Answer: A
Rationale: Demeclocycline inhibits ADH action in the kidneys, treating SIADH (caused by small cell lung cancer) by promoting water excretion to correct hyponatremia.
Question 2 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 3 of 5
A 76-year-old man with a history of falls, hypertension, and kidney stones presents to his primary care physician for follow-up. His blood pressure is 140 / 100~mmHg. He is placed on hydrochlorothiazide. This agent may be helpful in prevention of renal stones through which of the following mechanisms?
Correct Answer: C
Rationale: Hydrochlorothiazide increases renal tubular calcium reabsorption, reducing urinary calcium and preventing calcium-based kidney stones.
Question 4 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 5 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.
