A nurse is reinforcing teaching with a client about increasing her intake of fiber. Which of the following foods should the nurse encourage the client to eat?

Choice A reason: WBC count 10,000/mm³ is within the normal range of 4,500 to 11,000/mm³ and does not indicate any infection or inflammation.

Choice B reason: BUN 20 mg/dL is within the normal range of 10 to 20 mg/dL and does not indicate any renal impairment or dehydration.

Choice C reason: Creatinine 2.3 mg/dL is above the normal range of 0.6 to 1.2 mg/dL and indicates renal dysfunction or damage, which can be caused by blood loss, hypotension, or nephrotoxic drugs during surgery. The nurse should report this value to the provider and monitor the client for signs of acute kidney injury, such as oliguria, edema, or electrolyte imbalances.

Choice D reason: Hematocrit 41% is within the normal range of 37% to 47% for females and does not indicate any anemia or polycythemia.

Choice A: This is correct. Phototherapy is a treatment option for psoriasis that involves exposing the skin to ultraviolet light, which can reduce inflammation and slow down the growth of skin cells.

Choice B: This is incorrect. Oil-based ointment is not recommended for psoriasis, as it can clog the pores and worsen the condition.

Choice C: This is incorrect. Dermabrasion is a cosmetic procedure that involves removing the outer layer of skin with a rotating device, which can cause bleeding, infection, and scarring.

Choice D: This is incorrect. Benzoyl peroxide is an acne medication that can dry out and irritate the skin, which can aggravate psoriasis.
