A client who has polycystic kidney disease (PKD) presents to the emergency department with reports of a severe headache. Which of the following complications should the nurse expect?

Choice A reason: Ice cream is considered a fluid in dietary terms, so not counting it as part of fluid intake shows a misunderstanding.

Choice B reason: Making a list of favorite beverages does not demonstrate understanding of fluid restrictions.

Choice C reason: Putting beverages in large containers does not reffect an understanding of fluid restrictions and could lead to overconsumption.

Choice D reason: Consuming most fluid during the evening could lead to fluid overload overnight, which is not advisable.

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.
