Question 1 of 5
Urinary potassium concentrations are measured before and after several weeks of administering a loop diuretic (typical daily dosages). We find that post-treatment urine K⁺ concentrations are substantially lower than those measured at baseline. Which of the following is the most likely explanation for this observation?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
A patient with compromised renal hemodynamics is given a trial of mannitol. Of the following, which is the least likely to be associated with the effect of mannitol?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
A 75-year-old woman with type 2 diabetes has recently been placed on glipizide (Glucotrol), 10 mg daily. She asks the nurse when the best time would be to take this medication. What is the nurse’s best response?
Correct Answer: A
Rationale: The correct answer is A: Take this medication in the morning, 30 minutes before breakfast. Glipizide is a sulfonylurea medication that helps lower blood sugar levels by stimulating the pancreas to release more insulin. Taking it in the morning, before breakfast, helps synchronize the peak action of the medication with the body's natural rise in blood sugar levels in the morning. This timing helps prevent hypoglycemia during the night and early morning hours when the risk is higher. Choice B is incorrect because taking the medication in the evening may increase the risk of hypoglycemia during the night. Choice C is incorrect as there is no specific requirement to take the medication after the midday meal. Choice D is incorrect because the timing of glipizide intake does matter for optimal effectiveness and safety.
Question 4 of 5
After starting treatment for type 2 diabetes mellitus 6 months earlier, a patient is in the office for a follow-up examination. The nurse will monitor which laboratory test to evaluate the patient’s adherence to the antidiabetic therapy over the past few months?
Correct Answer: B
Rationale: The correct answer is B: Hemoglobin A1C level. Hemoglobin A1C reflects average blood glucose levels over the past 2-3 months, providing a better assessment of long-term glycemic control. This is important in evaluating the patient's adherence to antidiabetic therapy over the past few months. Choice A (Hemoglobin levels) is not as specific to monitoring diabetes control as Hemoglobin A1C. Choice C (Fingerstick fasting blood glucose level) provides a snapshot of glucose levels at a single point in time, not reflecting long-term control. Choice D (Serum insulin levels) does not directly measure the patient's adherence to antidiabetic therapy or overall glycemic control.
Question 5 of 5
Which hormone acts through a cytoplasmic receptor:
Correct Answer: A
Rationale: Calcitriol, the active form of vitamin D, acts through a cytoplasmic receptor. First, calcitriol enters the cell and binds to its cytoplasmic receptor. Then, the hormone-receptor complex translocates to the nucleus, where it regulates gene expression. This mechanism is characteristic of hormones that act through cytoplasmic receptors. Prolactin and vasopressin, on the other hand, act through cell surface receptors, triggering signaling cascades without entering the cell. Therefore, the correct answer is A (Calcitriol), as it follows the characteristic pathway of a hormone acting through a cytoplasmic receptor.
