Free Certified Registered Nurse First Assistant (AORN) Questions and Answers — Questions and Answers
Question 1: Debridement of wounds:
- Keeps a wound moist
- Closes a wound
- Removes dead tissue from a wound (Correct answer)
- Cleans a wound
Correct answer: Removes dead tissue from a wound
Debridement is a critical step in wound care that involves the removal of necrotic (dead) tissue, foreign material, and exudate from a wound bed. This process is essential because dead tissue can harbor bacteria, impede granulation tissue formation, and delay wound healing. By removing devitalized tissue, debridement promotes a clean wound environment conducive to healthy tissue growth and closure.
Question 2: Prolonged prone stance has the following risks:
- Increased post-operative pain
- Substantial blood loss
- Wound dehiscence
- Eye injury including temporary or permanent blindness (Correct answer)
Correct answer: Eye injury including temporary or permanent blindness
In the prone position, especially during prolonged surgeries, the eyes are vulnerable to direct pressure, which can compromise ocular blood flow. This sustained pressure can lead to ischemic optic neuropathy, resulting in temporary or permanent vision loss or even blindness. Careful positioning, frequent checks, and appropriate head support are crucial to prevent this severe complication.
Question 3: In a continuous suture, which stitches are tied?
- The first and last stitch (Correct answer)
- Every third stitch
- The last stitch
- Every other stitch
Correct answer: The first and last stitch
A continuous suture involves a single strand of suture material that is run along the length of the wound without being tied off after each stitch. To secure the entire suture line, only the very first stitch is tied to anchor the suture, and then the final stitch at the end of the run is tied to complete the closure. This method provides a quick and efficient way to approximate tissues.
Question 4: The patient's nurse informed her that she should remain in bed following her needle liver biopsy. The patient questioned why she was required to remain in bed after the surgery. What is the patient to be taught by the nurse?
- Resting in bed will stop the patient from falling because anesthetic will be administered.
- Bed rest is maintained in order to prevent stitches from opening
- There is a high risk of bleeding post biopsy due to liver vascularity. (Correct answer)
- The patient will be tired after the procedure and should get some rest.
Correct answer: There is a high risk of bleeding post biopsy due to liver vascularity.
The liver is a highly vascular organ, meaning it has a rich blood supply. A needle liver biopsy involves puncturing the liver, which carries a significant risk of bleeding or hemorrhage from the biopsy site. Therefore, post-procedure bed rest, often in a right lateral position, is crucial to apply pressure to the biopsy site and minimize the risk of bleeding complications by allowing the puncture site to seal.
Question 5: Which of the following acts as warfarin's (Coumadin) counterbalance?
- Vitamin K (Correct answer)
- Magnesuim
- Protamine sulfate
- Saline
Correct answer: Vitamin K
Warfarin (Coumadin) is an anticoagulant that works by interfering with the synthesis of vitamin K-dependent clotting factors in the liver. Therefore, Vitamin K acts as its direct antidote or counterbalance. Administering Vitamin K can reverse the anticoagulant effects of warfarin by promoting the production of these clotting factors, which is crucial in cases of excessive bleeding or overdose.
Question 6: To determine the arterial blood flow to the hands during an evaluation, what test is used?
- Finkel steins Test
- Cozens Test
- Allens Test (Correct answer)
- Wrist Press
Correct answer: Allens Test
The Allen's Test is a clinical assessment used to evaluate the patency of the radial and ulnar arteries, which supply blood to the hand. It is performed before procedures that might compromise one of these arteries, such as arterial blood gas sampling or radial artery cannulation. The test helps ensure that there is adequate collateral circulation to the hand from the other artery if one is occluded.
Question 7: What is the process of repositioning the bladder flap peritoneum to the posterior cul-de-sac peritoneum known as?
- 8.8-10
- reperitonealization (Correct answer)
- 3.5-5.0
- fimbria
Correct answer: reperitonealization
Reperitonealization is a surgical technique, often performed during gynecological procedures like hysterectomy, where the peritoneum (the membrane lining the abdominal cavity) is reapproximated or repositioned. Specifically, repositioning the bladder flap peritoneum to the posterior cul-de-sac peritoneum aims to cover raw surfaces, prevent adhesions, and restore anatomical integrity. This helps to minimize potential complications and promote healing.
