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.

Correct Answer is D
Explanation
Emptying the urine drainage bags at least once per shift is a task that can be delegated to unlicensed assistive personnel (UAP) assigned to a cardiac surgery unit.
This task does not require assessment, teaching, or evaluation skills that are beyond the scope of practice of UAP.
Choice A is wrong because teaching a client how to use a pillow to support an incision when coughing requires education and evaluation skills that are only within the scope of practice of licensed nurses.
Choice B is wrong because checking the pedal pulses of bed-bound clients requires assessment skills that are only within the scope of practice of licensed nurses.
Pedal pulses are important indicators of peripheral circulation and vascular status.
Choice C is wrong because ambulating the first-day postoperative clients requires assessment and evaluation skills that are only within the scope of practice of licensed nurses.
First-day postoperative clients may have complications such as bleeding, infection, or hypotension that need to be monitored by a nurse.
Correct Answer is A
Explanation
“I will discard unused pills after six months after replacing it with a new vial.” This statement indicates that the client understands that nitroglycerin tablets lose their potency over time and need to be replaced regularly.
Choice B is wrong because nitroglycerin can cause headaches as a side effect, but the client should not stop taking it if they have chest pain. They can use Tylenol for pain relief.
Choice C is wrong because nitroglycerin can cause hypotension and dizziness, so the client should avoid lying down or changing positions suddenly after taking it. They should sit or stand still until the chest pain subsides.
Choice D is wrong because a tingling feeling on the tongue is a normal sensation when taking sublingual nitroglycerin and does not indicate an adverse reaction. It also confirms that the tablet is potent and effective.
