Which of the following statements accurately reflects the relationship between obesity and surgical risk?
Obesity only affects the risk of surgical complications in certain surgical procedures.
Obesity has no impact on surgical risk.
Obesity decreases the risk of surgical complications.
Obesity increases the risk of surgical complications.
The Correct Answer is D
A. Obesity does not selectively affect only certain types of surgical procedures; rather, it generally increases the risk of complications across a wide range of surgical interventions. This includes both elective and emergency surgeries.
B. Obesity significantly impacts surgical risk. It is associated with a higher likelihood of complications such as wound infections, delayed wound healing, respiratory problems, and cardiovascular issues. The presence of excess body fat affects multiple physiological systems and can complicate both the surgical procedure and recovery.
C. Obesity does not decrease the risk of surgical complications; rather, it increases it. The excess body fat associated with obesity can lead to problems such as impaired wound healing, increased risk of infection, cardiovascular strain, and respiratory issues, which all contribute to a higher risk of complications during and after surgery.
D. This statement accurately reflects the relationship between obesity and surgical risk. Obesity is associated with an increased risk of a variety of surgical complications.

Correct Answer is B
Explanation
A. Lubricating the suction catheter tip with sterile saline is generally not recommended. The catheter tip is usually not lubricated before suctioning. Instead, suctioning should be performed using a dry, sterile catheter to prevent introducing any substances into the airway that could cause irritation or infection.
B. Hyperoxygenating the patient with 100% oxygen before suctioning is a crucial step. This helps to prevent hypoxia during the suctioning procedure, as suctioning can temporarily reduce the oxygen levels in the blood. By providing 100% oxygen for 30 to 60 seconds, the nurse ensures that the patient has an adequate oxygen reserve and reduces the risk of oxygen desaturation during suctioning.
C. Performing chest physiotherapy is not a routine pre-suctioning action and is generally done as part of a separate management strategy for clearing secretions. Chest physiotherapy involves techniques such as percussion, vibration, and postural drainage to help mobilize secretions from the lungs.
D. Instilling normal saline into the airway before suctioning (known as “normal saline lavage”) is not recommended. This practice can actually cause harm, such as increasing the risk of infection, causing bronchospasm, and diluting secretions which may then become more difficult to suction.
Correct Answer is A
Explanation
A. Slow and steady bubbling in the suction control chamber is expected and indicates that the system is functioning properly. It is designed to regulate the pressure within the chest cavity by allowing excess air and fluid to escape, ensuring that the lungs can re-expand properly
B. Checking for leaks is are unnecessary as the system is functioning as expected.
C. Checking the suction control outlet is are unnecessary as the system is functioning as expected.
D. Clamping the chest tube is are unnecessary as the system is functioning as expected.
