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
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 D
Explanation
A. Lymphocytes are a type of white blood cell that plays a crucial role in the immune system, specifically in the response to infections and in immune regulation. They do not have a role in the transport of oxygen in the blood.
B. Neutrophils are another type of white blood cell that is essential for fighting bacterial infections. They are part of the body's immune response but do not transport oxygen.
C. Platelets are small cell fragments that are crucial for blood clotting and wound repair. They do not have a role in oxygen transport.
D. Hemoglobin is the primary molecule responsible for transporting oxygen in the blood. It is a protein found in red blood cells (erythrocytes) that binds to oxygen in the lungs and releases it in tissues throughout the body. Hemoglobin carries the majority of oxygen in the bloodstream and is essential for effective oxygen transport and delivery.
Correct Answer is A
Explanation
A. This helps prevent air leaks and maintains the closed drainage system's function.
B. Looping the tubing on the client's is incorrect as it can lead to inaccurate drainage and measurement of the fluid.
C. Placing the drainage system above the level of the client's heart is incorrect as it can lead to inaccurate drainage and measurement of the fluid.
D. Routine stripping of the chest tube is also not recommended as it can cause trauma to the pleura and potentially lead to complications.
