A client with chronic kidney disease (CKD) is prescribed a low-potassium diet. Which food choice indicates to the nurse that the client understands the dietary restrictions?
Baked potato with skin.
Orange juice.
White rice.
Banana smoothie.
The Correct Answer is C
Choice A reason: Baked potato with skin is high in potassium (about 900 mg), unsuitable for CKD, where impaired renal excretion risks hyperkalemia, causing cardiac arrhythmias. White rice is low-potassium, aligning with dietary restrictions, demonstrating understanding of the need to limit potassium intake in renal disease.
Choice B reason: Orange juice contains high potassium (about 500 mg per cup), dangerous in CKD, as reduced glomerular filtration increases hyperkalemia risk, affecting cardiac conduction. White rice, with minimal potassium, complies with restrictions, indicating the client’s understanding of safe dietary choices for kidney function.
Choice C reason: White rice is low in potassium (about 50 mg per cup), appropriate for CKD, where the kidneys cannot excrete excess potassium, risking hyperkalemia and arrhythmias. Choosing white rice shows the client understands the low-potassium diet, supporting safe management of renal disease and electrolyte balance.
Choice D reason: Banana smoothie is high in potassium (about 400 mg per banana), contraindicated in CKD, where hyperkalemia risks cardiac instability due to poor renal clearance. White rice, low in potassium, reflects dietary compliance, demonstrating the client’s understanding of restrictions to prevent electrolyte imbalances.

Correct Answer is C
Explanation
Choice A reason: Thick, dry, dark areas on heels suggest chronic skin changes, not early pressure ulcers. Persistent redness over bone is the earliest sign (Stage 1). This indicates later damage, per pressure injury staging and prevention protocols in nursing care for immobile clients.
Choice B reason: Broken skin indicates a Stage 2 pressure ulcer, beyond the earliest stage. Persistent redness (Stage 1) signals initial tissue compromise. Broken skin requires intervention but is not the earliest sign, per pressure ulcer assessment and prevention standards in nursing practice.
Choice C reason: Persistent redness over bone is the earliest sign of a Stage 1 pressure ulcer, indicating tissue compromise due to pressure. Early intervention prevents progression in bedrest clients with heart failure, per pressure injury prevention and skin assessment protocols in nursing care.
Choice D reason: A superficial sacral ulcer (Stage 2) is more advanced than persistent redness (Stage 1), the earliest sign. Redness allows earlier intervention to prevent ulceration. Ulcers indicate progression, per pressure ulcer staging and prevention guidelines for immobile clients in nursing.
Correct Answer is A
Explanation
Choice A reason: Smoking exacerbates PAD via nicotine-induced vasoconstriction and endothelial damage, reducing blood flow and worsening atherosclerosis, especially post-MI. Cessation is critical to halt vascular damage, improve endothelial function, and prevent further MI or limb ischemia, addressing the primary pathophysiological driver of disease progression in this high-risk client.
Choice B reason: Reducing saturated fats and salt lowers LDL cholesterol and blood pressure, mitigating atherosclerosis in PAD and MI. However, smoking directly causes vasoconstriction and plaque progression, making cessation more urgent. Dietary changes are secondary, as nicotine’s immediate vascular effects pose a greater risk to perfusion and cardiovascular health.
Choice C reason: Trimming toenails short prevents injury in PAD, where poor perfusion impairs healing. However, smoking cessation is more critical, as nicotine’s vasoconstrictive effects directly reduce arterial flow, worsening ischemia. Nail care is a minor preventive measure compared to addressing smoking, the primary contributor to PAD’s pathophysiology.
Choice D reason: Applying a heating pad is contraindicated in PAD, as reduced sensation increases burn risk, and heat doesn’t improve arterial insufficiency. Smoking cessation is paramount, as nicotine exacerbates vasoconstriction, reducing blood flow and risking tissue necrosis. Cessation directly addresses PAD’s vascular pathology, making it the priority instruction.
