A nurse is caring for a client who is 8 hr postoperative following a left hip arthroplasty. Which of the following laboratory values indicates the nurse should notify the provider?

Choice A: This is incorrect because applying lotion between the toes can create a moist environment that promotes fungal growth and infection. The client should apply lotion to the feet but avoid the areas between the toes.

Choice B: This is incorrect because wearing open-toe shoes can expose the feet to injury and infection. The client should wear well-fitting, closed-toe shoes that protect the feet and prevent pressure ulcers.

Choice C: This is correct because wearing cotton socks can help keep the feet dry and prevent fungal infections. Cotton socks also provide cushioning and reduce friction.

Choice D: This is incorrect because rounding the corners of the toenails can cause ingrown nails, which can lead to infection and ulceration. The client should trim the toenails straight across and file any sharp edges.

Choice C Hemoglobin 8.6 g/dL indicates the nurse should notify the provider because it is below the normal range of 12 to 18 g/dL and suggests blood loss or anemia, which can impair oxygen delivery to tissues and affect wound healing.

Choice a is not correct because blood glucose 98 mg/dL does not indicate the nurse should notify the provider because it is within the normal range of 70 to 110 mg/dL and does not indicate hyperglycemia or hypoglycemia, which can affect recovery.

Choice b is not correct because BUN 18 mg/dL does not indicate the nurse should notify the provider because it is within the normal range of 10 to 20 mg/dL and does not indicate renal impairment or dehydration, which can affect fluid and electrolyte balance.

Choice d is not correct because potassium 3.5 mEq/L does not indicate the nurse should notify the provider because it is within the normal range of 3.5 to 5 mEq/L and does not indicate hypokalemia or hyperkalemia, which can affect cardiac function and muscle contraction.
