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?
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 A: This is incorrect because blood glucose 98 mg/dL is within the normal range of 70 to 110 mg/dL. The nurse does not need to notify the provider for this value.
Choice B: This is incorrect because BUN 18 mg/dL is within the normal range of 10 to 20 mg/dL. The nurse does not need to notify the provider for this value.
Choice C: This is correct because hemoglobin 8.6 g/dL is below the normal range of 12 to 18 g/dL. The nurse should notify the provider for this value as it indicates anemia, which can be caused by blood loss during surgery or impaired bone marrow function.
Choice D: This is incorrect because potassium 3.5 mEq/L is within the normal range of 3.5 to 5.0 mEq/L. The nurse does not need to notify the provider for this value.

Correct Answer is A
Explanation
Choice A reason: Applying a motion sensor mat to the client's bed is an appropriate action to prevent wandering and alert the staff if the client tries to get out of bed.
Choice B reason: Moving the overbed table away from the bed is not an effective action to prevent wandering, as it does not restrict the client's mobility or provide any supervision.
Choice C reason: Raising all four side rails while the client is in bed is an inappropriate action that can increase the risk of injury or entrapment if the client attempts to climb over them.
Choice D reason: Leaving the television on in the client's room is not an effective action to prevent wandering, as it does not provide any stimulation or distraction for the client.
Correct Answer is B
Explanation
Choice A reason: Nonpalpable area of redness, less than 5 mm (0.2 in) in diameter is a negative result for the tuberculin skin test, which means that the client does not have tuberculosis infection or exposure.
Choice B reason: Palpable area of induration, greater than 10 mm (0.4 in) in diameter is a positive result for the tuberculin skin test, which means that the client has tuberculosis infection or exposure and needs further testing, such as chest x-ray or sputum culture, to confirm the diagnosis and rule out active disease.
Choice C reason: Area of ecchymosis, greater than 12 mm (0.5 in) in diameter is not a relevant finding for the tuberculin skin test, as it indicates bruising or bleeding under the skin that may be caused by trauma or coagulation disorder.
Choice D reason: Tenderness at the injection site is not a relevant finding for the tuberculin skin test, as it indicates inflammation or irritation of the skin that may be caused by needle insertion or allergic reaction.
