Which statement by a nurse may undermine a patient’s feelings and belittle the patient’s concerns?

Choice A reason: Hourly nursing assessments are important for monitoring safety in restraints but are not the primary legal requirement. Assessments ensure no physical harm, but psychiatric evaluation within one hour is mandated to confirm restraint necessity, making this option secondary in priority for immediate post-restraint protocol.

Choice B reason: Constant supervision may be used, but transitioning to video monitoring after one hour does not meet strict regulatory standards for restraints. Face-to-face psychiatric evaluation within one hour is required to assess ongoing need and ensure patient rights, making this option less accurate for legal compliance.

Choice C reason: Regulatory standards (e.g., CMS, Joint Commission) mandate a face-to-face evaluation by a psychiatrist within one hour of initiating restraints to assess necessity, safety, and alternatives. This ensures compliance with mental health laws, protects patient rights, and prevents overuse, making it the required action.

Choice D reason: Reviewing restraint appropriateness hourly is part of ongoing care but is not the primary requirement. A psychiatrist’s face-to-face evaluation within one hour takes precedence to ensure legal and ethical use, as it confirms the clinical justification for restraints, making this option secondary.

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.
