When the nurse discontinues a 24-hour postoperative client’s patient-controlled analgesia (PCA) pump, the client asks to go to the hospital’s smoking area to smoke a cigarette. Which response should the nurse provide?

“Your PCA pump has just been discontinued, and you need to wait at least one hour before leaving the unit.”

“As long as you go to the smoking area in a wheelchair, it will be all right for you to go smoke.”

“You may smoke in your room if you keep the door closed and open a window.”

“Smoking is hazardous to your health, and since you just had surgery, it would be best for you to avoid smoking.”

Answer and Explanation

The Correct Answer is D

Choice A reason: Delaying smoking for one hour is arbitrary and does not address smoking’s risks post-surgery. Nicotine causes vasoconstriction, reducing wound perfusion, and carbon monoxide impairs oxygen delivery, delaying healing. Advising against smoking mitigates these risks, promoting recovery, making this response less effective than cessation advice.

Choice B reason: Allowing smoking in a wheelchair ignores postoperative risks. Nicotine’s vasoconstriction reduces tissue oxygenation, and carbon monoxide lowers hemoglobin’s capacity, impairing healing. This increases infection or thrombosis risk. Advising against smoking addresses these physiological harms, prioritizing wound recovery over facilitating smoking, which is detrimental.

Choice C reason: Smoking in the room violates hospital safety and exposes others to secondhand smoke. Nicotine and carbon monoxide reduce tissue perfusion and oxygen delivery, delaying postoperative healing. Advising against smoking prevents these complications, ensuring better recovery, making this response unsafe and inappropriate for surgical patients.

Choice D reason: Advising against smoking is critical, as nicotine causes vasoconstriction, reducing blood flow to surgical sites, and carbon monoxide impairs oxygen delivery, delaying healing. These increase infection and thrombosis risks post-surgery. This response promotes optimal recovery, addressing physiological needs for wound healing in the critical 24-hour period.

Correct Answer is B

Explanation

Choice A reason: A soft diet with milk products may worsen diverticulosis, as dairy can cause bloating or intolerance. High fiber and fluids prevent constipation, reducing diverticular pressure. This is inappropriate, per dietary management and gastrointestinal health guidelines for diverticulosis in nursing education.

Choice B reason: A high fiber diet and increased fluid intake prevent constipation, reducing pressure in diverticula and preventing complications like diverticulitis. This promotes bowel regularity, critical for managing diverticulosis, per evidence-based dietary recommendations and gastrointestinal health protocols in patient education for nursing care.

Choice C reason: Small frequent meals and sitting up after meals aid digestion but do not address diverticulosis-specific needs. High fiber and fluids directly prevent constipation, reducing diverticular strain. This is less effective, per dietary management and patient teaching standards for diverticulosis in nursing.

Choice D reason: A bland diet avoiding spicy foods is unrelated to diverticulosis, which requires fiber to prevent constipation. Spicy foods do not directly affect diverticula. High fiber and fluids are critical, per gastrointestinal health and dietary management guidelines for diverticulosis in nursing education.

A. Discontinue the use of the nasal cannula. B. Decrease the flow rate to 1 L/minute. C. Apply lubricant to the cannula tubing. D. Place padding around the cannula tubing.

Correct Answer is D

Explanation

Choice A reason: Discontinuing the nasal cannula is inappropriate, as 94% SpO₂ indicates mild hypoxemia from pneumonia, requiring oxygen to support alveolar diffusion. The rash likely results from cannula pressure, not oxygen delivery. Padding addresses the rash without compromising respiratory support, ensuring continued therapy.

Choice B reason: Decreasing to 1 L/minute may worsen hypoxemia in pneumonia, where inflamed alveoli impair gas exchange (SpO₂ 94%). The rash is from mechanical irritation, not flow rate. Padding relieves pressure, maintaining oxygen delivery to improve saturation, making flow reduction counterproductive to respiratory needs.

Choice C reason: Applying lubricant reduces friction but not pressure causing the red macular rash from prolonged cannula contact. Lubricants risk aspiration. Padding alleviates pressure points, preventing skin breakdown while maintaining oxygen for pneumonia, addressing the rash’s mechanical cause more effectively than lubrication.

Choice D reason: Placing padding around the cannula tubing relieves pressure on the cheek, preventing skin breakdown from the red macular rash. This maintains oxygen at 3 L/minute, critical for pneumonia’s hypoxemia, where inflamed alveoli reduce oxygen diffusion. Padding ensures skin integrity and respiratory support, addressing both issues effectively.
