A nurse is teaching a client who has chronic kidney failure about planning a low-protein diet. The client states, "Why do I have to be concerned about protein?" Which of the following responses should the nurse make?

"A low-protein diet reduces the risk for edema."

"A low-protein diet will reduce the risk for hyperkalemia

"A low-protein diet will increase the nitrogenous wastes in the blood."

"A low protein diet reduces the risk for uremia."

Answer and Explanation

The Correct Answer is D

A.   Edema in chronic kidney failure is more closely associated with sodium and water retention rather than protein intake.
B.   Hyperkalemia in chronic kidney failure can be managed by restricting dietary potassium intake, but it is not primarily related to protein intake.
C.   A low-protein diet aims to decrease, not increase, nitrogenous wastes in the blood.
D.   A low-protein diet reduces the risk for uremia, a condition resulting from chronic kidney failure where urea and other waste products build up in the body due to impaired renal function. A low-protein diet helps decrease the workload on the kidneys by reducing the amount of nitrogenous waste they need to filter and excrete.

Correct Answer is A

Explanation

A. Creatinine levels rise in acute kidney injury due to impaired kidney function, as the kidneys are unable to effectively filter creatinine from the blood.
B. BUN (blood urea nitrogen) levels typically increase in dehydration due to reduced kidney perfusion, leading to decreased urine output and increased concentration of waste products in the blood.
C. Specific gravity increases in hypovolemia because urine becomes more concentrated as the body tries to conserve water.
D. Potassium levels may vary depending on the cause of polyuria, but polyuria itself does not necessarily cause hyperkalemia. It can be caused by various factors including diabetes insipidus or diabetes mellitus.

A. Urine output of 50 mL in 4hr B. Respiratory rate of 16/min C. Diminished deep tendon reflexes D. Heart rate of 56/min

Correct Answer is B

Explanation

A. A urine output of 50 mL in 4 hours is inadequate and may indicate decreased renal perfusion. Magnesium sulfate can further compromise renal perfusion, so this finding warrants careful evaluation and potential adjustment of the infusion rate.
B. This indicates that the client is not experiencing respiratory depression, a potential side effect of magnesium sulfate toxicity.
C. Diminished deep tendon reflexes is an expected finding in magnesium sulfate toxicity.
D. A heart rate of 56/min is below the normal range for an adult but may be a common finding in clients receiving magnesium sulfate due to its cardiac depressant effects.
