A nurse is providing an in-service on potassium-wasting diuretics for the unit.
Which of the following medications should not be included in the in-service? (Select All That Apply.)
Furosemide.
NaoxGhe.
Spironolactone.
None of the above.
Correct Answer : B,C
Choice A rationale
Furosemide is a loop diuretic that inhibits the sodium-potassium-chloride co-transporter in the thick ascending limb of the loop of Henle. This results in significant loss of potassium in the urine.
Choice B rationale
NaoxGhe is not a recognized diuretic or medication and should not be included in any in-service discussion.
Choice C rationale
Spironolactone is a potassium-sparing diuretic that works by antagonizing the effects of aldosterone in the distal tubules, reducing potassium excretion.
Choice D rationale
"None of the above" is not a medication but rather a non-relevant option in this context.

Correct Answer is A
Explanation
Choice A rationale
Prazosin, an alpha-blocker, is often started at the lowest dose and taken at night to minimize the risk of orthostatic hypotension, a sudden drop in blood pressure upon standing.
Choice B rationale
Starting prazosin at the highest dose is not recommended due to the risk of severe orthostatic hypotension, which can lead to dizziness and fainting.
Choice C rationale
It is important to monitor blood pressure with the first dose of prazosin to assess the patient's response and avoid significant drops in blood pressure.
Choice D rationale
Prazosin may take several weeks to achieve full therapeutic effect. It does not control hypertension within a week.
Correct Answer is B
Explanation
Choice A rationale
While metformin is commonly used as a first-line medication for type 2 diabetes, this choice does not specifically address a critical safety concern related to metformin.
Choice B rationale
Metformin can interact with contrast dyes used in imaging studies, increasing the risk of acute renal failure due to lactic acidosis. Patients need to be aware of this interaction to avoid potential complications.
Choice C rationale
Metformin is used to lower blood glucose levels, not increase them. This choice is incorrect.
Choice D rationale
While metformin is associated with less weight gain compared to other diabetes medications, this choice does not address the critical interaction with contrast dye.
