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
Levofloxacin (Levaquin) is a fluoroquinolone antibiotic that is not structurally related to penicillin and has a very low risk of cross-reactivity with penicillin.
Levofloxacin can be safely used in patients with penicillin allergy unless they have a history of hypersensitivity to other fluoroquinolones.
Choice A is wrong because cephalexin (Keflex) is a first-generation cephalosporin that has a similar side chain to some penicillins and may cause cross-reactivity in penicillin-allergic patients. The risk of cross-reactivity is higher for first- and second-generation cephalosporins than for third- and fourth-generation cephalosporins.
Choice B is wrong because cefaclor (Ceclor) is a second-generation cep
Correct Answer is B
Explanation
Select a 0.5 mL syringe, 30 gauge, 8 mm needle and inject at a 90-degree angle. This is because Humulin R is a clear and colorless solution that can be given by subcutaneous injection.
A 0.5 mL syringe can hold up to 50 units of insulin, which is enough for the prescribed dose of 7 units. A 30 gauge, 8 mm needle is suitable for thin patients with poor skin turgor. Injecting at a 90-degree angle ensures that the insulin reaches the subcutaneous tissue and not the muscle.
Choice A is wrong because a 31 gauge, 6 mm needle is too short and may not deliver the insulin into the subcutaneous tissue.
Choice C is wrong because pinching the skin is not necessary for thin patients with poor skin turgor.
Choice D is wrong because a 1.0 mL syringe is too large for the prescribed dose of 7 units and may cause dosing errors. A 28 gauge, 12.7 mm needle is too long and may inject the insulin into the muscle, which can affect its absorption and action.
