A nurse is reviewing the medical history of a patient who is preoperative for surgery. Which of the following findings places the patient at risk for a postoperative complication?

Obstructive sleep apnea

Glucose level 75 mg/dL

BMI 24

Increased anxiety

Answer and Explanation

The Correct Answer is A

Choice A reason: Obstructive sleep apnea can increase the risk of postoperative complications due to potential breathing problems and the eﬀects of anesthesia.

Choice B reason: A glucose level of 75 mg/dL is within the normal fasting range (70-99 mg/dL) and does not typically place a patient at increased risk for postoperative complications.

Choice C reason: A BMI of 24 falls within the normal weight range (18.5-24.9) and is not considered a risk factor for postoperative complications.

Choice D reason: While increased anxiety can aﬀect a patient's experience, it is not a direct risk factor for postoperative complications like obstructive sleep apnea is.

Correct Answer is A

Explanation

Choice A reason: Hyperventilation is a compensatory mechanism in metabolic acidosis where the body tries to decrease carbon dioxide levels to balance the acidity.

Choice B reason: Cold, clammy skin is not a typical manifestation of metabolic acidosis; it may be associated with shock or hypoglycemia.

Choice C reason: Increased blood pressure is not directly related to metabolic acidosis. It can be inﬂuenced by various factors, including stress or other underlying conditions.

Choice D reason: Bradycardia, or a slow heart rate, is not a common manifestation of metabolic acidosis. Tachycardia, or a fast heart rate, might be observed instead.

A. "Perform deep breathing every 2 hours around the clock." B. "Make sure chest and shoulders move when breathing." C. "Take a deep breath before each atempt to cough." D. "Sit up straight before beginning coughing exercises." E. Use a pillow to support the area when coughing

Correct Answer is ["A","C","D","E"]

Explanation

Choice A reason: Performing deep breathing exercises every 2 hours helps prevent postoperative complications such as pneumonia and atelectasis.

Choice B reason: While chest movement is part of breathing, the instruction is incomplete and should emphasize diaphragmatic breathing rather than shoulder movement.

Choice C reason: Taking a deep breath before coughing helps to increase the eﬀectiveness of the cough, which can clear secretions from the lungs.

Choice D reason: Sitting up straight before beginning coughing exercises helps to ensure maximum lung expansion and eﬀectiveness of the cough.

Choice E reason: Using a pillow to support the surgical area when coughing can help reduce pain and protect the incision site, making the cough more eﬀective.
