A nurse is caring for a client who is 1 hr postoperative following a left hip arthroplasty. Which of the following laboratory values indicates the nurse should notify the provider?
Blood glucose 98 mg/dL
BUN 18 mg/dL
Hemoglobin 8.6 g/dL
Potassium 3.5 mEq/L
The Correct Answer is C
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.

Correct Answer is C
Explanation
Choice c: Confusion is a finding that the nurse should anticipate in an older adult client who has cystitis, which is inflammation of the bladder caused by a bacterial infection. Confusion can be a sign of sepsis or delirium, which are common complications of urinary tract infections in older adults.
Choice a is not correct because hypothermia is not a finding that the nurse should anticipate in an older adult client who has cystitis. Hypothermia can occur in older adults due to impaired thermoregulation, but it is not related to cystitis.
Choice b is not correct because referred pain in the right shoulder is not a finding that the nurse should anticipate in an older adult client who has cystitis. Referred pain in the right shoulder can indicate gallbladder disease, but it is not related to cystitis.
Choice d is not correct because orange-colored urine is not a finding that the nurse should anticipate in an older adult client who has cystitis. Orange-colored urine can be caused by certain medications, foods, or dehydration, but it is not related to cystitis.
Correct Answer is B
Explanation
Choice A: This is incorrect. Potassium 4.0 mEq/L is a normal value and does not indicate heart failure.
Choice B: This is correct. Brain natriuretic peptide (BNP) is a hormone that is released by the heart when it is stretched or overloaded. A high level of BNP indicates that the heart is working harder than normal and may have heart failure. A normal BNP level is less than 100 pg/mL, so 275 pg/mL is elevated and suggestive of heart failure.
Choice C: This is incorrect. Sodium 140 mEq/L is a normal value and does not indicate heart failure.
Choice D: This is incorrect. Calcium 9.0 mg/dL is a normal value and does not indicate heart failure.
