Perioperative Care Fundamentals Practice Questions Quizlet Questions
Question 1 of 5
The instrument devices depicted below are designed to ligate, divide, resect, suture, and anastomose tissue. They are commonly called:
Correct Answer: D
Rationale: Choice D as mechanical staplers perform these functions. Choices A, B, and C are inaccurate. This speeds surgery, a perioperative nursing support.
Question 2 of 5
Four hours after mechanical ventilation is initiated for a patient with chronic obstructive pulmonary disease (COPD), the patient's arterial blood gas (ABG) results include a pH of 7.51, PaO₂ of 82 mm Hg, PaCO₂ of 26 mm Hg, and HCO₃ of 23 mEq/L (23 mmol/L). The nurse will anticipate the need to
Correct Answer: D
Rationale: Choice D as respiratory alkalosis (pH 7.51, PaCOâ‚‚ 26 mm Hg) from over-ventilation requires a lower rate. Increasing FIOâ‚‚ (choice A), volume (choice B), or rate (choice C) worsens alkalosis. This aligns with NCLEX physiological integrity, adjusting ventilation to normalize ABGs in COPD care.
Question 3 of 5
A patient who is orally intubated and receiving mechanical ventilation is anxious and is fighting the ventilator. Which action should the nurse take next?
Correct Answer: A
Rationale: Choice A as coaching reduces anxiety and synchronizes breathing, avoiding sedation risks. Lorazepam (choice B) or propofol (choice D) may be secondary, and manual ventilation (choice C) is unnecessary. This prioritizes physiological integrity per NCLEX, promoting non-invasive solutions in critical care.
Question 4 of 5
A 48-year-old patient with a comminuted fracture of the left femur has Buck's traction in place while waiting for surgery. To assess for pressure areas on the patient's back and sacral area and to provide skin care, the nurse should
Correct Answer: D
Rationale: Choice D as self-lifting maintains traction alignment while allowing skin assessment. Loosening traction (choice A) or turning (choices B, C) disrupts immobilization, risking fracture displacement. This aligns with NCLEX Safe and Effective Care Environment, balancing skin integrity with orthopedic stability in pre-surgical care.
Question 5 of 5
The day after a having a right below-the-knee amputation, a patient complains of pain in the right foot. Which action is best for the nurse to take?
Correct Answer: B
Rationale: Choice B as phantom pain, common post-amputation, requires immediate analgesia like other postoperative pain. Explaining (choice A) or predicting relief (choice D) doesn't address current distress, and loosening bandages (choice C) risks bleeding. This aligns with NCLEX Physiological Integrity, prioritizing pain management in acute care.
