A nurse is teaching about preventing constipation to a client who has a new prescription for oxycodone. Which of the following statements by the client indicates an understanding of the teaching?

Choice A reason: Avoiding reading for 3 months is not a standard instruction post-retinal detachment surgery. Reading may be restricted temporarily (e.g., 1-2 weeks) if specific positioning is required, but 3 months is excessive. Patients are typically advised to avoid straining, not reading, making this instruction incorrect.
Choice B reason: Bending at the waist increases intraocular pressure, which can disrupt retinal repair and lead to re-detachment. Patients should bend at the knees to avoid straining the eye. This instruction is harmful and contraindicated, as it risks complications in the healing retina.
Choice C reason: Lifting objects up to 50 pounds is dangerous post-retinal surgery, as heavy lifting increases intraocular pressure, risking re-detachment. Guidelines typically restrict lifting to 10-20 pounds during recovery (4-6 weeks). This instruction is incorrect, as it poses a significant risk to surgical outcomes.
Choice D reason: Taking a stool softener daily prevents straining during bowel movements, which can increase intraocular pressure and disrupt retinal healing. Constipation is a concern post-surgery due to immobility or pain medications, and stool softeners ensure safe bowel movements, making this the correct instruction.

Choice A reason: Anuria, minimal or no urine output, is expected in end-stage kidney disease (ESKD) due to nephron loss, reducing glomerular filtration rate. This causes fluid and toxin buildup, requiring dialysis to manage fluid balance and prevent complications like uremia in ESKD clients.
Choice B reason: Edema results from impaired sodium and water excretion in ESKD, causing fluid overload. Reduced filtration leads to volume retention, manifesting as peripheral or pulmonary edema, increasing cardiovascular strain and necessitating diuretics or dialysis to control fluid status effectively.
Choice C reason: Hyperkalemia occurs in ESKD, as failing kidneys cannot excrete potassium, elevating serum levels. This risks cardiac arrhythmias due to disrupted membrane potentials. Dietary restrictions or dialysis are needed to manage potassium, preventing life-threatening complications in end-stage renal failure.
Choice D reason: Hypocalcemia in ESKD stems from impaired vitamin D activation and phosphate retention, binding calcium. This disrupts bone mineralization and neuromuscular function, causing tetany or fractures. Calcium supplementation and dialysis correct this imbalance, addressing renal failure’s metabolic consequences.
Choice E reason: Metabolic acidosis in ESKD results from impaired hydrogen ion excretion and bicarbonate reabsorption. This lowers blood pH, causing fatigue and bone demineralization. Dialysis or bicarbonate therapy corrects acid-base imbalances, addressing the kidneys’ failure to maintain homeostasis in end-stage disease.
