A nurse is teaching a client who has acute kidney injury about dietary sources of potassium. Which of the following statements by the client indicates an understanding of the teaching?

"I will enjoy eating cantaloupe for my morning snack."

"I can easily add baked potatoes to my diet."

"Eating yogurt will be a new experience."

"Adding pecans will be a change I can readily make."

Answer and Explanation

The Correct Answer is D

Choice A rationale: Cantaloupe is high in potassium. Clients with acute kidney injury (AKI) have impaired potassium excretion, and consuming high-potassium foods increases the risk of hyperkalemia, which can lead to cardiac arrhythmias.

Choice B rationale: Baked potatoes contain significant potassium, especially in the skin. In AKI, potassium retention is dangerous, so this choice reflects poor understanding of dietary restrictions for renal safety.

Choice C rationale: Yogurt is rich in potassium and phosphorus. In AKI, both electrolytes may accumulate due to reduced renal clearance, making yogurt an inappropriate choice without close monitoring.

Choice D rationale: Pecans are low in potassium, making them a safer snack for clients with AKI. Choosing low-potassium foods demonstrates appropriate understanding of renal dietary management.

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.

A. pH 7.30, HCO3- 26 mEq/L, PaCO2 50 mm Hg B. pH 7.55, HCO3- 30 mEq/L, PaCO2 31 mm Hg C. pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg D. pH 7.50, HCO3- 20 mEq/L, PaCO2 32 mm Hg

Correct Answer is C

Explanation

Choice A reason: pH 7.30 with elevated HCO3- and PaCO2 suggests compensated respiratory acidosis, not typical for chronic kidney disease.

Choice B reason: pH 7.55 with elevated HCO3- and low PaCO2 suggests metabolic alkalosis, which is not typical for chronic kidney disease.

Choice C reason: pH 7.25 with decreased HCO3- and PaCO2 suggests metabolic acidosis, which is expected in chronic kidney disease due to the accumulation of acids.

Choice D reason: pH 7.50 with low HCO3- and PaCO2 suggests compensated metabolic alkalosis, which is not typical for chronic kidney disease.
