A patient on dialysis asks why he is receiving aluminum hydroxide gel (Amphojel), a phosphate binder, for his renal disorder. What should the nurse explain regarding the action of that Amphojel?
Increases the appetite
Corrects the pH of the bowel
Calms the frequent upset stomach experienced by patients on dialysis
Binds with phosphorus to increase the serum calcium level
The Correct Answer is D
A. Increases the appetite: Aluminum hydroxide does not have an appetite-stimulating effect.
B. Corrects the pH of the bowel: Aluminum hydroxide does not directly alter bowel pH; it is used to bind phosphate.
C. Calms the frequent upset stomach experienced by patients on dialysis: Although aluminum hydroxide can reduce stomach acid, its primary use in this context is as a phosphate binder.
D. Binds with phosphorus to increase the serum calcium level: Aluminum hydroxide binds dietary phosphorus in the gastrointestinal tract, reducing serum phosphorus levels. This helps manage the calcium-phosphorus balance, preventing complications like bone demineralization.

Correct Answer is D
Explanation
A. Equal to the excretion of urea: Urea excretion contributes to osmolality but does not define it.
B. In a ratio of 10:1 with the serum: This is not a recognized ratio for urine and serum osmolality.
C. Approximately half of the serum: In a healthy kidney, urine osmolality may vary but typically equals serum osmolality in a state of balance.
D. Equal to the osmolality of the serum: Under normal conditions, the kidney regulates urine osmolality to maintain a balance with serum osmolality, reflecting adequate kidney function.
Correct Answer is D
Explanation
A. The antibiotic protocol is completed: While antibiotics may be used for secondary infections, they are not directly related to lifting activity restrictions.
B. Potassium levels are normal: Potassium levels are relevant to kidney function but do not dictate bed rest.
C. Dialysis starts: Dialysis is not typically required in acute glomerulonephritis unless there is severe kidney failure.
D. Blood pressure drops to normal levels: In acute glomerulonephritis, hypertension is a common complication, and activity is often restricted until blood pressure stabilizes.
