Perioperative Care Practice Questions Questions
Question 1 of 5
During a hypermetabolic MH crisis, the patient will require major modalities of treatment. In addition to dantrolene what is another priority intervention?
Correct Answer: B
Rationale: Choice B as cooling reduces hyperthermia. Choices A, C, and D are secondary or irrelevant. This stabilizes the patient, a perioperative nursing action.
Question 2 of 5
The primary use for suture is essentially to:
Correct Answer: B
Rationale: Choice B as sutures ligate, approximate, and close wounds. Choices A, C, and D miss key functions. This supports healing, a perioperative nursing role.
Question 3 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 4 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 5 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.
