An 85-year-old patient returns to the inpatient surgical unit after leaving the PACU. Which of the following place the patient at risk during surgery? Select all that apply
Stiffened lung tissue
Reduced diaphragmatic excursion
Increased laryngeal reflexes
Reduced blood flow to kidneys
Increased cholinergic transmission
Correct Answer : A,B,D
Older adults have predictable physiologic changes (pulmonary stiffness, reduced diaphragmatic movement, diminished airway reflexes, decreased renal perfusion, altered pharmacodynamics) that lower physiologic reserve and increase vulnerability to anesthesia and surgical stress.
Rationale for correct answers:
1. Stiffened lung tissue: Aging causes decreased lung elasticity and increased chest-wall stiffness, reducing pulmonary compliance and reserve. This increases the risk of hypoventilation, atelectasis, and postoperative pulmonary complications.
2. Reduced diaphragmatic excursion: Older adults often have weaker respiratory muscles and reduced chest-wall mobility, which limits diaphragmatic movement. This promotes shallow breathing and inability to clear secretions effectively.
4. Reduced blood flow to kidneys: Renal blood flow and glomerular filtration decline with age. Reduced renal perfusion decreases drug clearance and increases susceptibility to renal injury and fluid/electrolyte imbalances during and after surgery.
Rationale for incorrect answers:
3. Increased laryngeal reflexes: Aging typically reduces protective airway reflexes (gag/cough), which increases risk of aspiration.
5. Increased cholinergic transmission: Normal aging is associated with a decline in cholinergic neurons/transmission; increased cholinergic activity is not typical and would not explain common geriatric perioperative risks.
Take home points:
- Anticipate respiratory and renal vulnerabilities in elderly surgical patients.
- Many protective reflexes and neurotransmitter activities decline with age.

Correct Answer is C
Explanation
Postoperative gas pain commonly results from anesthetic effects, decreased bowel motility, swallowed air, and manipulation of the bowel. Promoting early and frequent ambulation, position changes, and encouraging passing flatus are the most effective nonpharmacologic measures.
Rationale for correct answer:
3. Encourage frequent ambulation: Ambulation stimulates intestinal motility and helps move trapped gas, reducing distention and discomfort. It’s a first-line, low-risk intervention.
Rationale for incorrect answers:
1. Cough and deep breathe every 2 hours: Coughing and deep breathing primarily prevent pulmonary complications (atelectasis) and do not directly relieve intestinal gas.
2. Maintain NPO status for 48 hours: Prolonged NPO is unnecessary for routine gas pain and may delay return of bowel function; early oral intake as tolerated and activity often help.
4. Take vital signs every 4 hours: Monitoring vitals is important for overall postop care but will not directly relieve gas pain.
Take home points:
- Early ambulation is the single most effective nursing intervention to relieve postoperative gas pain by stimulating bowel motility.
- Use multimodal measures - positioning, ambulation, analgesia to allow activity, and ordered medications such as simethicone.
Correct Answer is ["A","C","D"]
Explanation
Certain chronic conditions (diabetes, obesity, respiratory impairment) predispose clients to complications such as infection, poor healing, and respiratory compromise. Identifying these risks allows the nurse to implement preventive measures.
Rationale for correct answers:
1. Obesity increases surgical risk because excess adipose tissue reduces blood supply to tissues, impairs wound healing, and increases strain on the respiratory and cardiovascular systems. It also makes positioning and anesthesia management more difficult.
3. Delayed wound healing: Diabetes interferes with tissue perfusion and impairs immune response, increasing the risk of delayed wound healing and postoperative infections.
4. Ineffective vital capacity: Obesity can restrict chest expansion, reduce lung volume, and impair effective ventilation. This puts the client at higher risk for atelectasis and hypoxemia postoperatively.
Rationale for incorrect answers:
2. Prolonged bleeding time: There’s no evidence in the scenario that this client has a bleeding disorder. Prolonged bleeding time is a concern with anticoagulant therapy or platelet dysfunction, not specifically linked to this patient.
5. Immobility secondary to height: Height alone is not a risk factor for immobility or surgical complications. Immobility is more commonly associated with obesity, fractures, or neurologic impairment.
Take home points:
- Obesity and diabetes significantly increase surgical risks due to poor wound healing, infection risk, and respiratory limitations.
- Risk assessment guides pre- and post-op nursing care e.g., strict glucose control, pulmonary hygiene, infection prevention.
