A client with end-stage kidney disease is scheduled to begin hemodialysis. The nurse is working with the client to adapt the client’s diet to maximize the therapeutic effect and minimize the risks of complications. The client’s diet should include which of the following modifications?

Increased potassium intake

Increased protein intake

Decreased phosphorus intake

Decreased calcium intake/supplementation

Answer and Explanation

The Correct Answer is C

Choice A reason: Increased potassium intake is dangerous in ESRD, as impaired kidneys cannot excrete potassium, leading to hyperkalemia. This can disrupt cardiac membrane potentials, causing arrhythmias or cardiac arrest. ESRD diets require strict potassium restriction to prevent life-threatening electrolyte imbalances, making this modification inappropriate.

Choice B reason: Increased protein intake is often recommended in ESRD patients on hemodialysis to replace protein lost during dialysis and prevent malnutrition. However, it must be balanced to avoid excess urea production, which can worsen uremia. This is not the primary focus compared to phosphorus management in this context.

Choice C reason: Decreased phosphorus intake is critical in ESRD, as kidneys cannot excrete phosphate, leading to hyperphosphatemia. This causes vascular calcification and secondary hyperparathyroidism, increasing cardiovascular risk. Dietary phosphorus restriction, often with phosphate binders, prevents these complications, making it a key dietary modification for hemodialysis patients.

Choice D reason: Decreased calcium intake is not recommended in ESRD, as patients often have hypocalcemia due to impaired vitamin D activation and phosphate retention. Calcium supplementation or adequate intake is needed to prevent bone disease and secondary hyperparathyroidism, making this modification incorrect for ESRD management.

Free Nursing Study Resources

Correct Answer is C

Explanation

Choice A reason: Allowing a client with suicidal comments to leave against medical advice is unsafe, as it risks self-harm without immediate intervention. Providing resources does not address acute suicide risk, which requires inpatient stabilization to ensure safety, making this action inappropriate in the context of expressed suicidal ideation.

Choice B reason: Contacting family to persuade the client to stay does not address immediate suicide risk. While family support may be helpful, it lacks legal authority to prevent discharge and does not ensure safety, making it less effective than initiating a commitment for a client with suicidal intent.

Choice C reason: A 302 involuntary commitment is appropriate for a client expressing suicidal ideation, indicating imminent danger to self. This legal action ensures safety through inpatient evaluation and treatment, preventing self-harm. Mental health laws prioritize protection in such cases, making this the most appropriate nursing action.

Choice D reason: Calling security to detain the client is coercive and lacks legal basis without a formal commitment process. It may escalate agitation and violate autonomy. A 302 commitment is the proper legal mechanism to ensure safety for a suicidal client, making detention by security inappropriate.

A. Increased red blood cell count B. Decreased serum potassium level C. Increased serum creatinine level D. Increased serum calcium level

Correct Answer is C

Explanation

Choice A reason: Renal failure impairs erythropoietin production, a hormone stimulating red blood cell synthesis, leading to anemia, not an increased red blood cell count. Reduced glomerular filtration exacerbates toxin accumulation, further suppressing bone marrow activity, making an elevated red blood cell count unlikely in this condition.

Choice B reason: In renal failure, kidneys fail to excrete potassium, leading to hyperkalemia, not decreased serum potassium. Hyperkalemia can cause cardiac arrhythmias due to altered membrane potentials. A decreased potassium level is more associated with conditions like diuretic use or vomiting, not renal failure.

Choice C reason: Increased serum creatinine is a hallmark of renal failure, as kidneys cannot filter creatinine, a muscle metabolism byproduct. Elevated levels reflect reduced glomerular filtration rate, indicating kidney dysfunction. This is a reliable marker for assessing renal failure severity and progression, making it an expected finding.

Choice D reason: Renal failure typically causes hypocalcemia, not increased serum calcium, due to impaired vitamin D activation and phosphate retention, which binds calcium. Hypercalcemia is rare and may occur in other conditions like hyperparathyroidism, not renal failure, where calcium homeostasis is disrupted by kidney dysfunction.
