A 59-year-old male patient is scheduled for a hemorrhoidectomy. The OR nurse should anticipate assisting the other team members with positioning the patient in what manner?
- A. Dorsal recumbent position
- B. Trendelenburg position
- C. Sims position
- D. Lithotomy position
Correct Answer: D
Rationale: The lithotomy position is used for nearly all perineal, rectal, and vaginal surgical procedures. The Sims or lateral position is used for renal surgery and the Trendelenburg position usually is used for surgery on the lower abdomen and pelvis. The usual position for surgery, called the dorsal recumbent position, is flat on the back, but this would be impracticable for rectal surgery.

An intraoperative nurse is applying interventions that will address surgical patients risks for perioperative positioning injury. Which of the following factors contribute to this increased risk for injury in the intraoperative phase of the surgical experience? Select all that apply.
- A. Absence of reflexes
- B. Diminished ability to communicate
- C. Loss of pain sensation
- D. Nausea resulting from anesthetic
- E. Reduced blood pressure
Correct Answer: A,B,C
Rationale: Loss of pain sense, reflexes, and ability to communicate subjects the intraoperative patient to possible injury. Nausea and low blood pressure are not central factors that contribute to this risk, though they are adverse outcomes.
As an intraoperative nurse, you are the advocate for each of the patients who receives care in the surgical setting. How can you best exemplify the principles of patient advocacy?
- A. By encouraging the patient to perform deep breathing preoperatively
- B. By limiting the patients contact with family members preoperatively
- C. By maintaining each of your patients privacy
- D. By eliciting informed consent from patients
Correct Answer: C
Rationale: Patient advocacy in the OR entails maintaining the patients physical and emotional comfort, privacy, rights, and dignity. Deep breathing is not necessary before surgery and obtaining informed consent is the purview of the physician. Family contact should not be limited.
The circulating nurse will be participating in a 78-year-old patients total hip replacement. Which of the following considerations should the nurse prioritize during the preparation of the patient in the OR?
- A. The patient should be placed in Trendelenburg position.
- B. The patient must be firmly restrained at all times.
- C. Pressure points should be assessed and well padded.
- D. The preoperative shave should be done by the circulating nurse.
Correct Answer: C
Rationale: The vascular supply should not be obstructed by an awkward position or undue pressure on a body part. During surgical procedures, the patient is at risk for impairment of skin integrity due to a stationary position and immobility. An elderly patient is at an increased risk of injury and impaired skin integrity. A Trendelenburg position is not indicated for this patient. Once anesthetized for a total hip replacement, the patient cannot move; restraints are not necessary. A preoperative shave is not performed; excess hair is removed by means of a clipper.
The perioperative nurse has completed the presurgical assessment of an 82-year-old female patient who is scheduled for a left total knee replacement. When planning this patients care, the nurse should address the consequences of the patients aging cardiovascular system. These include an increased risk of which of the following?
- A. Hypervolemia
- B. Hyponatremia
- C. Hyperkalemia
- D. Hyperphosphatemia
Correct Answer: A
Rationale: The aging heart and blood vessels have decreased ability to respond to stress. Reduced cardiac output and limited cardiac reserve make the elderly patient vulnerable to changes in circulating volume and blood oxygen levels. There is not an increased risk for hyponatremia, hyperkalemia, or hyperphosphatemia because of an aging cardiovascular system.
The nurse is performing wound care on a 68-year-old postsurgical patient. Which of the following practices violates the principles of surgical asepsis?
- A. Holding sterile objects above the level of the nurses waist
- B. Considering a 1 inch (2.5 cm) edge around the sterile field as being contaminated
- C. Pouring solution onto a sterile field cloth
- D. Opening the outermost flap of a sterile package away from the body
Correct Answer: C
Rationale: Whenever a sterile barrier is breached, the area must be considered contaminated. Pouring solution onto a sterile field cloth violates surgical asepsis because moisture penetrating the cloth can carry microorganisms to the sterile field via capillary action. The other options are practices that help ensure surgical asepsis.
