Which of the following factors is NOT associated with a higher risk of post-surgical complications in obese patients?

Higher risk of respiratory complications due to decreased lung function

Increased risk of cardiovascular events due to strain on the heart

Increased risk of infection due to impaired wound healing

Decreased risk of blood clots due to improved circulation

Answer and Explanation

The Correct Answer is D

A.   Obese patients often have decreased lung function due to reduced chest wall compliance and increased abdominal pressure, which can impair respiratory mechanics. This leads to a higher risk of respiratory complications such as hypoventilation, atelectasis, and pneumonia post-surgery.

B.   Obesity places additional strain on the cardiovascular system, increasing the risk of cardiovascular events like hypertension, heart attack, and stroke. This strain is compounded during surgery due to increased cardiac workload and potential fluid shifts.
C.   Obesity impairs wound healing due to several factors, including decreased oxygenation to tissues, impaired immune function, and increased adipose tissue which can create a moist environment conducive to infection. This increases the risk of postoperative infections.
D.   In fact, obesity is associated with an increased risk of blood clots (venous thromboembolism) due to reduced mobility, chronic inflammation, and altered coagulation factors. Obesity does not improve circulation; rather, it often exacerbates venous stasis and clot formation.

Correct Answer is ["100"]

Explanation

To calculate the rate at which the IV pump should be set to deliver the medication, you would use the formula:

(Total Volume in mL / Time in hours) = mL/hr.

The total volume of the IV bag is 50 mL and the time frame is 0.5 hours (since 30 minutes is half an hour). So, the calculation would be 50 mL / 0.5 hours = 100 mL/hr.

Therefore, the nurse should set the IV pump to deliver 100 mL/hr to administer 500 mg of ampicillin over 30 minutes.
