Perioperative Care Practice Questions Questions
Question 1 of 5
The circulating nurse instructed the new anesthesia resident in the proper positioning of the arm and hands on the OR bed armboards. She cautioned him to avoid pressure on the elbow to prevent:
Correct Answer: A
Rationale: Choice A as elbow pressure risks ulnar nerve injury. Choices B, C, and D are less specific. This protects nerve function, a perioperative nursing concern.
Question 2 of 5
Surgical instruments that are not considered in the category of clamps, retractors, or cutting instruments, but are used in most procedures, are typically included within the category of:
Correct Answer: D
Rationale: Choice D as accessory instruments enhance basics. Choices A, B, and C are specialized. This facilitates procedures, a perioperative nursing role.
Question 3 of 5
When assisting with the placement of a pulmonary artery (PA) catheter, the nurse notes that the catheter is correctly placed when the monitor shows a
Correct Answer: D
Rationale: Choice D as PAWP confirms correct catheter placement when the balloon wedges in a pulmonary artery branch. PA waveform (choice A) appears post-deflation, while systemic pressure (choice B) and SVR (choice C) relate to arterial lines or calculations. This aligns with NCLEX physiological integrity, ensuring accurate measurement of left heart pressures critical for ICU management.
Question 4 of 5
A patient with respiratory failure has arterial pressure-based cardiac output (APCO) monitoring and is receiving mechanical ventilation with peak end-expiratory pressure (PEEP) of 12 cm Hâ‚‚O. Which information indicates that a change in the ventilator settings may be required?
Correct Answer: A
Rationale: Choice A as hypotension (90/46 mm Hg) suggests high PEEP may reduce venous return, necessitating adjustment. Normal heart rate (choice B), increased stroke volume (choice C), and variation (choice D) don't indicate distress. This reflects NCLEX physiological integrity, evaluating PEEP's impact on circulation.
Question 5 of 5
The nurse educator is evaluating the performance of a new registered nurse (RN) who is providing care to a patient who is receiving mechanical ventilation with 15 cm Hâ‚‚O of peak end-expiratory pressure (PEEP). Which action indicates that the new RN is safe?
Correct Answer: B
Rationale: Choice B is correct, per page 859, as closed-suction preserves PEEP (>10 cm Hâ‚‚O), ensuring safety. Routine suctioning (choice A), taping (choice C), or tubing changes (choice D) risk harm or instability. This aligns with NCLEX safe care, confirming competence in high-PEEP ventilation management.
