A nurse is caring for a client who is in the diuresis phase of acute kidney injury. The nurse should closely monitor the client for what complication during this phase?

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.

Choice A reason: While behavior acceptability varies across cultures, this statement does not fully define mental health or illness. Cultural norms influence behavior interpretation, but mental health involves emotional and psychological well-being, not just cultural acceptability, making this option incomplete as a definition of mental health or illness.

Choice B reason: Mental health is characterized by emotional, psychological, and social well-being, reflected in adaptive coping strategies like problem-solving or seeking support. This holistic state enables individuals to manage stress and function effectively, making this statement a comprehensive and accurate description of mental health in contrast to mental illness.

Choice C reason: Engaging in fantasies is not inherently indicative of mental illness, as it can be a normal part of creativity or coping. Only when fantasies disrupt functioning or reflect delusions does it suggest illness. This statement is inaccurate, as it overgeneralizes a common behavior as pathological.

Choice D reason: Determining mental health or illness via verbal and nonverbal communication is complex and not always reliable. Cultural, individual, and contextual factors obscure interpretation, and clinical assessment requires comprehensive evaluation beyond communication, making this statement inaccurate as a definitive method for assessing mental health status.
