Q21Which of the following is a crucial step in the preoperative phase for a patient getting ready for a kidney transplant?
✓ Correct answer: D. 【2】Assessing the patient’s teeth for gingivitis and tooth decay
As part of the preoperative process for a patient undergoing a kidney transplant, it is crucial to evaluate the patient's oral health for signs of gingivitis and tooth decay. Due to the increased risk of infection, patients receiving a kidney transplant are particularly vulnerable. <br/><br/>Infections can originate from various sources, including the surgical procedure, and even minor infections can contribute to sepsis. <br/><br/>Patients with gum disease or tooth decay have oral infections that could potentially spread in an immunocompromised patient.
Q22The process of the body forming new blood cells is known as:
✓ Correct answer: C. 【2】Hematopoiesis
The correct answer is C) Hematopoiesis.<br/><br/>The process of the body forming new blood cells is known as hematopoiesis. <br/><br/>Blood tests are often performed prior to surgery to determine if the patient has adequate amounts of red and white blood cells. <br/><br/>Adequate levels of these cells indicate that the patient will have adequate oxygenation and the ability to fight infection.
Q23When cleaning the surgical environment after a procedure, what is the appropriate method for the nurse to dispose of contaminated linen?
✓ Correct answer: C. 【2】Place linen in a bag before putting it in a proper receptacle within the room."
When cleaning a room after a surgical procedure, it is important for the nurse to place linen in a bag before placing the bag in an appropriate receptacle within the room. By bagging the linen beforehand, exposure is minimized during transportation to the receptacle.<br/><br/>Utilizing collection sites that are in close proximity to the room is preferable as it reduces the risk of microorganism transmission compared to carrying the linen over a distance, such as along a hallway.
Q24The patient care plan should involve which of the following?
✓ Correct answer: C. 【3】All of the above
The patient care plan should involve:<br/><br/>Ensures perioperative safety<br/><br/>Helps to determine the infection prevention strategies<br/><br/>Identifies the patient's anticipated physiological responses<br/><br/>Helps to recognize the behavioral responses of the patient<br/><br/>Manage the patient's medications.
Q25According to Orem’s nursing systems theory, which nurse actions are warranted while the patient is considered wholly compensatory?
✓ Correct answer: A. 【2】Keeping the patient covered and draped while under anesthesia in the operating suite.
According to Orem’s nursing systems theory, one way that the nurse can provide care for the patient in a wholly compensatory state is by keeping the patient covered and draped while under anesthesia in the operating suite.<br/><br/>When a patient is classified as wholly compensatory, they are completely dependent on the nurse for their safety and support, a state that often occurs while they are unconscious during surgery. <br/><br/>Because they cannot care for themself during this time, the patient relies on the nurse to provide care and protection.
Q26Complications of positioning for patients during surgery would be considered more prevalent in which of the following patients?
✓ Correct answer: A. 【3】Both A and C
Complications of positioning for patients during surgery would be considered more prevalent in:<br/><br/>Pediatric patients-might need select aids according to their size and weight.<br/><br/>Elderly patients-have thin skin and an increase in arteriosclerosis causing them to be more prone to skin breakdown.<br/><br/>Patients with respiratory disorders- more prone to skin breakdown from the pressure during surgery.
Q27Which of the following measures can the nurse take to ensure adequate respiratory status and proper ventilation for the patient during the surgical procedure?
✓ Correct answer: D. 【1】Ensure that straps across the chest are secure but not overly tight.
The nurse can ensure adequate respiratory status and proper ventilation for the patient by ensuring the straps across the chest are secure but not overly tight. <br/><br/>Some patients need to be secured to the operating table by using chest straps; however, straps that are too tight may not allow for proper chest expansion. Placing the patient’s hands across the chest may also restrict chest movement.
Q28Of the following, which would be considered one of the highest priorities of the postanesthesia care?
✓ Correct answer: C. 【1】Pain control
Waking the patient up and allowing the family to visit are important, but in this case pain control would be considered the highest priority. at this time. The patient's pain level should be assessed on admission to the PACU unit and at regular, frequent intervals afterwards. Remember pain is a subjective thing.
Q29Which of the following solutions are utilized to effectively manage both gram-positive and gram-negative bacteria during the surgical skin preparation process?
✓ Correct answer: D. 【1】Chlorhexidine gluconate
Chlorhexidine gluconate, a solution employed in surgical skin preparation, effectively targets both gram-positive and gram-negative bacteria. <br/><br/>This solution exhibits a gentle nature towards the skin and acts rapidly. Not only does it diminish the presence of bacteria on the skin during the prep, but it also impedes the subsequent regrowth of bacteria in the area.
Q30The surgeon is in the process of performing a midline abdominal incision and has successfully made incisions through the skin and subcutaneous fat. <br/><br/>Moving forward, which anatomical layer lies beneath the subcutaneous fat and will be the surgeon's next target for incision?
✓ Correct answer: C. 【1】Fascia
The fascia, located beneath the subcutaneous fat in the abdomen, is an integral layer involved in making a midline incision. This connective tissue layer serves as a protective barrier for the muscles and nerves within the abdomen, and it may possess fibrous characteristics.
