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 A reason: Discouraging reminiscing about the past is not a helpful strategy for a client who has dementia and confusion. Reminiscing can stimulate memory, enhance mood, and promote social interaction.
Choice B reason: Asking open-ended questions that encourage the client to express their feelings is not appropriate for a client who has dementia and confusion. Open-ended questions can increase frustration and anxiety for the client who may have difficulty finding words or recalling events. The nurse should use simple, direct, and closed-ended questions instead.
Choice C reason: Using holiday decorations to provide orientation to the time of the year is a beneficial action for a client who has dementia and confusion. Holiday decorations can help the client recognize familiar cues and reduce disorientation.
Choice D reason: Encouraging multiple family members to visit the client at the same time is not advisable for a client who has dementia and confusion. Multiple visitors can overwhelm and agitate the client who may have trouble recognizing faces or voices. The nurse should limit the number of visitors and ensure they are calm and supportive.
Correct Answer is A
Explanation
Choice A: This is correct. Dehydration can cause electrolyte imbalance and affect the brain function, leading to confusion, dizziness, or lethargy.
Choice B: This is incorrect. Cool, clammy skin is a sign of shock, not dehydration. Dehydration can cause dry, warm skin.
Choice C: This is incorrect. Decrease in pulse rate is a sign of bradycardia, not dehydration. Dehydration can cause increase in pulse rate as the body tries to compensate for the low blood volume.
Choice D: This is incorrect. Increase in blood pressure is a sign of hypertension, not dehydration. Dehydration can cause decrease in blood pressure as the blood volume drops.
