Q1While assessing a patient in recovery from abdominal surgery, a perioperative nurse observes an alarming occurrence: blood flowing out of the incision site, followed by loops of intestine.<br/><br/>What immediate intervention is required in the case of an abdominal evisceration?
Show answer
✓ Correct answer: 【3】Both B and C
The correct answer is D) Both B and C.<br/><br/>In the event of an abdominal evisceration, the nurse should promptly notify the surgeon about the need for surgical intervention and place sterile dressings moistened with saline over the exposed intestines. <br/><br/>An abdominal evisceration is a critical complication that can occur due to postoperative wound dehiscence. <br/><br/>To safeguard the intestines from harm and minimize the risk of infection, the nurse should cover the wound and await the arrival of the surgeon, rather than attempting to reposition the abdominal contents.

Q5The perioperative nurse is caring for a patient with a chest tube when they notice an extensive amount of bubbling in the water seal chamber of the device. The patient has developed cyanosis and shallow breathing. <br/><br/>What is the nurse’s next action?
Show answer
✓ Correct answer: 【3】Notify the physician.
The correct answer is D) Notify the physician.<br/><br/>The nurse should notify the physician. If the water seal chamber starts bubbling excessively and there is not an outside leak, the patient could be retaining air within the pleural cavity. Based on the patient’s response of cyanosis and shallow breathing, the chest tube is not working correctly and the physician needs to be notified.
Q6When preparing to administer oxygen via a nasal cannula to a patient with low levels of oxygen in their blood, what is the correct sequence of connecting the various components starting from the oxygen source in the wall until reaching the patient?
Show answer
✓ Correct answer: 【1】Flow meter, connector, humidifier, tubing, patient
The correct answer is B) Flow meter, connector, humidifier, tubing, patient.<br/><br/>The oxygen is connected to the patient in a sequential order, starting from the wall source and moving through the flow meter, connector, humidifier, and tubing. <br/><br/>The flow meter, which is connected to the oxygen source, is responsible for regulating the amount of oxygen delivered to the patient. The oxygen then passes through the humidifier, where moisture is added to prevent drying. Finally, the oxygen is delivered to the patient through the tubing.
