A nurse is caring for a client following his first hemodialysis treatment. The client reports a headache, nausea, and restlessness. The nurse should identify these findings as manifestations of which of the following complications?

Choice A reason: Decreasing the IV fluid infusion rate and limiting oral fluid intake may not be appropriate without further assessment, as the client's BUN level is elevated, which could indicate dehydration or renal impairment. The normal range for BUN is typically 7-20 mg/dL.

Choice B reason: Collecting a urine specimen for culture and sensitivity may be necessary if there is a suspicion of infection, but there is no indication of infection based solely on the provided lab values.

Choice C reason: Evaluating urine for amount and specific gravity can help assess the client's hydration status and kidney function, which is pertinent given the elevated BUN level and ongoing nausea and vomiting.

Choice D reason: Continuing routine care may not be appropriate because the BUN level is above the normal range, indicating that further assessment and intervention may be necessary.

Choice A reason: Furosemide does not require a diet low in potassium; in fact, patients may need to increase their potassium intake due to its diuretic effect.

Choice B reason: Patients on furosemide should not limit fluid intake unless specifically instructed by their healthcare provider, as the medication is a diuretic.

Choice C reason: Furosemide is used to treat high blood pressure, so it would not cause an increase in blood pressure.

Choice D reason: Limiting sun exposure and wearing sunscreen is important as furosemide can make the skin more sensitive to sunlight.
