Final answer:
The patient needs additional education when making the statement about consuming cabbage and mushrooms while taking spironolactone.
Step-by-step explanation:
The patient needs additional education when making statement 4, "I am German, so I could not give up my cabbage and mushrooms."
Spironolactone (Aldactone) is a medication used as a diuretic that works by blocking the effects of a hormone called aldosterone. It can increase the levels of potassium in the blood, and therefore, patients taking spironolactone should avoid foods high in potassium.
Cabbage and mushrooms are both high in potassium, and consuming these foods while taking spironolactone can increase the risk of elevated potassium levels, which can lead to serious health problems. Therefore, the patient should be educated to avoid these foods while on spironolactone.
