Difficulty: EasyPreoperative and Postoperative Care

A male patient in his late sixties is assessed on the second morning after undergoing an elective laparotomy for recurrent diverticulitis. His vital signs show a temperature elevation to 38.5°C (101.3°F), pulse of 88/min, respirations of 18/min, and blood pressure of 135/85 mm Hg. Auscultation reveals diminished aeration at both lung bases without any crackles or wheezes. The surgical wound appears to be healing well with no signs of induration, erythema, or purulent discharge. He reports that his abdominal pain is a 7 out of 10 and restricts him from taking deep breaths. Which of the following interventions are most appropriate at this time? (Select 2)

  1. Promote targeted pulmonary expansion therapyAnswer
  2. B
    Initiate empiric antimicrobial therapy
  3. C
    Evaluate bilateral deep veins via Doppler imaging
  4. Titrate systemic or regional pain management regimensAnswer
  5. E
    Request cross-sectional abdominal imaging with contrast

Answer

The most appropriate next steps are to promote targeted pulmonary expansion therapy and titrate systemic or regional pain management regimens.
The correct options directly address the most common cause of fever on postoperative days 1 to 2, which is atelectasis. Patients undergoing major abdominal surgery often experience significant incisional pain, causing them to take shallow breaths (a phenomenon known as splinting). This leads to alveolar collapse and decreased clearance of airway secretions. Titrating pain management allows the patient to breathe deeply and cough effectively without severe discomfort. Concurrently, promoting pulmonary expansion therapy (such as using an incentive spirometer or doing deep breathing exercises) directly aids in recruiting collapsed alveoli, which resolves the atelectasis and suppresses the associated inflammatory response.

Step-by-Step Solution

1
Analyze the timeline and vital signs of the postoperative patient.
The patient has an elevated temperature on postoperative day 2.
Determining the exact timing is crucial for identifying the most likely etiology of a postoperative fever.
2
Evaluate the clinical signs and symptoms in context.
The patient has severe abdominal pain (7/10), shallow breathing, and diminished breath sounds at the lung bases bilaterally.
Severe incisional pain from a laparotomy causes splinting, which leads to shallow breathing, alveolar collapse, and subsequent atelectasis.
3
Select the appropriate management based on the likely diagnosis of atelectasis.
The patient requires aggressive pulmonary hygiene and optimized pain control.
Adequate pain management allows the patient to take deeper breaths without severe discomfort, while pulmonary expansion therapy directly forces collapsed alveoli open.
