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.
Q7Which of the following scenarios would be reported as a sentinel event, as per the Joint Commission's guidelines?
Show answer
✓ Correct answer: 【0】A patient who received surgery on the wrong part of the body

Show answer
✓ Correct answer: 【1】Negligence
Negligence occurs when a nurse fails to perform a standard of care that another reasonable and prudent nurse would perform. Negligent behavior by nurses often makes up malpractice court claims.<br/><br/>When a nurse is negligent in their behavior, they are acting without thinking, not paying attention to what they are doing, or they are being purposefully reckless.
Q9When preparing to assist a patient with walking for the first time after surgery, which of the following is not a factor to be considered when planning to provide help?
Show answer
✓ Correct answer: 【2】The amount of time needed
When preparing to help a patient walk, the amount of time needed is not necessarily a factor to be considered when planning to provide help. <br/><br/>The nurse should exercise patience with the person who is getting up for the first time, as being too eager or trying to move too quickly can result in falls or injuries. <br/><br/>The size of the room is important to determine if the patient has enough room to move around chairs or obstacles; the weight of the patient and use of assistive devices are necessary to determine how many people are needed for help.
