When the nurse discontinues a 24-hour postoperative client’s patient-controlled analgesia (PCA) pump, the client asks to go to the hospital’s smoking area to smoke a cigarette. Which response should the nurse provide?

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.

Choice A reason: Dry skin and inelastic turgor reflect dehydration in DI from antidiuretic hormone deficiency, causing water loss. This is less urgent than hypernatremia (185 mEq/L), which dehydrates brain cells, risking seizures or coma, requiring immediate fluid correction to prevent neurological damage in this critical condition.

Choice B reason: Tachycardia (110 beats/minute) compensates for hypovolemia in DI, where water loss reduces preload, triggering sympathetic activation. This is less critical than hypernatremia (185 mEq/L), which causes cerebral dehydration, necessitating urgent hypotonic fluids to prevent neurological complications, making heart rate secondary.

Choice C reason: Serum sodium of 185 mEq/L indicates severe hypernatremia in DI, where water loss concentrates sodium, dehydrating neurons and risking seizures or coma. Immediate IV hypotonic fluids (e.g., 5% dextrose) correct osmolarity, preventing life-threatening cerebral complications, addressing the urgent pathophysiological crisis in DI.

Choice D reason: Polyuria and thirst are hallmark DI symptoms from water loss but expected and less urgent than hypernatremia (185 mEq/L), which threatens neurological function via osmotic brain injury. Correcting sodium is critical to prevent seizures, making these symptoms secondary to urgent electrolyte management.
