A nurse is providing dietary teaching to a client who has a history of recurring calcium oxalate kidney stones. Which of the following instructions should the nurse include in the teaching?

Take 3,000 mg of vitamin C daily.

Drink 3 L of fluid every day.

Eat 12 oz of animal protein daily.

Restrict calcium intake to one serving per day.

Answer and Explanation

The Correct Answer is B

Choice A reason: Taking 3,000 mg of vitamin C daily is not recommended as it may increase the risk of calcium oxalate stones due to possible conversion of vitamin C to oxalate.

Choice B reason: Drinking 3 L of fluid every day is advised to prevent kidney stones by diluting the urine and reducing the concentration of stone-forming substances.

Choice C reason: Eating 12 oz of animal protein daily is excessive and can increase the risk of kidney stones due to higher excretion of calcium and oxalate.

Choice D reason: Restricting calcium intake to one serving per day is not recommended as a normal calcium intake is necessary to bind oxalate in the gut and reduce oxalate absorption.

Correct Answer is B

Explanation

Choice A reason: The erythrocyte sedimentation rate (ESR) is not directly aﬀected by epoetin alfa therapy, which is used to treat anemia.

Choice B reason: Epoetin alfa stimulates erythropoiesis, leading to an increase in red blood cell production, which would be reﬂected in an increased hematocrit level.

Choice C reason: The platelet count is not directly aﬀected by epoetin alfa therapy.

Choice D reason: The leukocyte count is not directly aﬀected by epoetin alfa therapy.

A. BUN 8 mg/dL and creatinine 0.7 mg/dL B. BUN 45 mg/dL and creatinine 8 ng/dL C. BUN 10 mg/dL and creatinine 0.3 mg/dL D. BUN 23 mg/dL and creatinine 1.0 mg/dL

Correct Answer is D

Explanation

Choice A reason: A BUN level of 8 mg/dL and a creatinine level of 0.7 mg/dL are within normal ranges for healthy individuals. In CKD, BUN and creatinine levels are typically elevated due to decreased kidney function.

Choice B reason: A BUN level of 45 mg/dL is elevated, which could be expected in CKD, but a creatinine level of 8 ng/dL is not correctly expressed. Creatinine is measured in mg/dL, and in CKD, it would be higher than normal, not lower.

Choice C reason: A BUN level of 10 mg/dL and a creatinine level of 0.3 mg/dL are both lower than what would typically be expected in a patient with CKD. CKD usually results in higher levels due to reduced kidney function.

Choice D reason: A BUN level of 23 mg/dL and a creatinine level of 1.0 mg/dL are more aligned with what might be expected in CKD. Normal BUN levels range from 7 to 20 mg/dL, and normal creatinine levels can vary based on age, sex, and body size. In CKD, both levels tend to be higher as the kidneys' ability to filter blood decreases.
