A client on digitalis has a lab report of potassium 3.0 mEq/L.
The nurse would instruct the client to eat which of these foods?
Asparagus.
Cantaloupe.
Blackberries.
Cucumbers.
Cucumbers.
The Correct Answer is B
The client on Digitalis has a low potassium level of 3.0 mEq/L, below the normal range of 3.5-5.0 mEq/L. Low potassium levels can increase the risk of digitalis toxicity, which can cause nausea, abdominal discomfort, visual changes, and cardiac arrhythmias.
The nurse would instruct the client to eat foods high in potassium, such as cantaloupe, to prevent or correct hypokalemia.
Choice A. Asparagus is wrong because asparagus is a low-potassium food that contains only 202 mg of potassium per cup.
Eating asparagus would not help to raise the client’s potassium level.
Choice C. Blackberries are wrong because blackberries are also a low-potassium food that contains only 233 mg of potassium per cup.
Eating blackberries would not help to raise the client’s potassium level.
Choice D. Cucumbers is wrong because cucumbers are a very low-potassium food that contains only 76 mg of potassium per cup.
Eating cucumbers would not help to raise the client’s potassium level and may even lower it further.

Insert a sterile needle and aspirate 3 to 5 mL of urine into the syringe. This is the best technique for obtaining a sterile urine specimen from an indwelling urinary catheter because it ensures that microorganisms in the specimen are from the urine, and not the result of contamination.
Choice B is wrong because it does not use sterile technique and it does not collect fresh urine. The urine in the drainage bag may have been sitting there for a long time and may not reflect the current condition of the patient’s urinary tract.
Choice C is wrong because it does not use sterile technique and it flushes the catheter with sterile water, which may dilute the urine and alter its composition.
Choice D is wrong because it does not use sterile technique and it collects urine from the drainage bag, which may be contaminated or stale.
