Which of the following would the nurse expect to find when reviewing the laboratory test results of a client with renal failure?
Increased red blood cell count
Decreased serum potassium level
Increased serum creatinine level
Increased serum calcium level
The Correct Answer is C
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.

Correct Answer is C
Explanation
Choice A reason: Restraining and forcibly administering medication violates patient autonomy and ethical principles, potentially escalating agitation in psychosis. It risks physical harm and legal issues, as forced medication requires specific legal orders (e.g., involuntary commitment). Non-invasive approaches like negotiation or assessing refusal reasons are safer and more ethical.
Choice B reason: Stating that refusal prevents improvement is coercive and undermines autonomy. It fails to explore reasons for refusal, such as side effect concerns or psychosis-related mistrust, which are common in severe psychosis. This approach may damage trust and hinder therapeutic alliance, making it inappropriate as an initial action.
Choice C reason: Accepting the client’s refusal respects autonomy while prioritizing safety, critical in psychosis where agitation is common. This allows exploration of refusal reasons (e.g., paranoia) and alternative interventions, maintaining a therapeutic environment. Monitoring ensures no immediate harm, making this the most ethical and safe initial response.
Choice D reason: Obtaining a discharge order for nonadherence is premature and inappropriate, as refusal does not warrant immediate discharge. Psychosis requires ongoing assessment and management, and discharge could exacerbate symptoms or risk harm, making this action contrary to the goal of stabilizing the client’s mental health.
Correct Answer is C
Explanation
Choice A reason: Administering IV normal saline addresses fluid volume deficits, not cloudy dialysate, which suggests peritonitis in CAPD. Saline does not treat infection or clarify drainage. Without addressing the potential infection, complications like sepsis or peritoneal membrane damage may occur, making this intervention irrelevant to the finding.
Choice B reason: Flushing the peritoneal catheter with saline risks introducing bacteria or dislodging clots, worsening potential infection. Cloudy dialysate indicates peritonitis, requiring assessment and likely antibiotics, not flushing. This action could compromise the catheter’s integrity and is not a standard intervention for suspected peritonitis in CAPD.
Choice C reason: Cloudy dialysate is a hallmark of peritonitis in CAPD, caused by bacterial infection. Assessing for fever, abdominal pain, or rebound tenderness confirms infection, enabling prompt antibiotic treatment. Early intervention prevents sepsis or peritoneal membrane scarring, which could necessitate dialysis modality change, making this the priority action.
Choice D reason: Continuing to monitor without assessing for infection delays treatment of potential peritonitis, a serious CAPD complication. Cloudy dialysate requires immediate evaluation, as untreated infection can lead to sepsis, peritoneal damage, or death. Passive monitoring risks patient safety, making this an inadequate response to a critical finding.
