NCLEX Perioperative Questions: Pre and Post Op

November 2, 2026 · 5 min read

Short answer. Perioperative NCLEX questions test preparation and early recognition. The items that matter are the consent, the checklist, and the postoperative findings that mean a complication rather than expected discomfort.

What the 2026 NCLEX tests in this area

Reduction of Risk Potential: surgical readiness, complications, monitoring
Safety and Infection Control: consent validity, surgical site verification, sterile technique

Key facts to know

Who can give informed consent	A competent adult. The provider explains the procedure, not the nurse
Nurse's role in consent	Verify it is signed, the client understands, and answer questions by clarifying, then notify if unclear
Malignant hyperthermia	Rigid muscles, rising temperature and tachycardia after anaesthesia. Treat with dantrolene
Most common postoperative complication	Atelectasis, prevented with incentive spirometry and early mobilisation
Signs of postoperative hemorrhage	Falling blood pressure, rising pulse, restlessness, and a dressing that is unexpectedly saturated
Early ambulation purpose	Prevents clots, pneumonia and ileus

Practice question from this chapter

The nurse is caring for a patient who had spinal anesthesia. What should the nurse assess postoperatively?

Sensation and movement of upper extremities
Cranial nerve function
Gag reflex
Sensation and movement of lower extremities

Show answer and rationale

Correct answer: D. Sensation and movement of lower extremities

with spinal anesthesia, the nurse should maintain supine position and check for sensation and movement of lower extremities.

Second practice question

A patient who had knee surgery reports sudden shortness of breath and chest pain on postoperative day 2. What is the nurse's priority action?

Place the patient in high Fowler's position, apply oxygen, and notify the provider
Ambulate the patient to prevent further clots
Massage the calf muscles
Administer the prescribed analgesic

Show answer and rationale

Correct answer: A. Place the patient in high Fowler's position, apply oxygen, and notify the provider

Sudden dyspnea and chest pain after surgery suggest a pulmonary embolism; oxygen, positioning, and immediate provider notification are the priorities.

Consent and the checklist

The surgeon obtains consent and explains the risks. The nurse confirms the form is signed, the client can state what the procedure is in their own words, and any question is routed back to the surgeon. A client who says they do not understand is not ready for surgery, regardless of a signature on the page.

The time out before incision confirms client identity, site, procedure and consent with the whole team present. Any option that skips it is wrong.

Postoperative deterioration

Restlessness and anxiety in the first hours after surgery are often the first sign of bleeding or hypoxia, not a personality problem. Check the dressing, the vital signs and the oxygen saturation before offering reassurance. Fever on day one is usually atelectasis, fever after day three suggests infection, and fever with a rigid client after anaesthesia suggests malignant hyperthermia.

Preparation is where items are won

Preoperative items test what you verify: identity, site, procedure, consent, allergies, nothing by mouth, and the baseline observations. The consent must be signed by a client who understands, and any question about risks goes back to the surgeon rather than being answered by the nurse.

Also review the medication list. Anticoagulants increase bleeding risk, and some herbal supplements do the same. A client who kept taking a supplement without mentioning it is a common stem.

Recognising a complication early

The first hours after anaesthesia are the highest risk period. Restlessness, tachycardia and falling urine output suggest bleeding. A saturation drop with shallow breathing and a low grade fever on day one or two suggests atelectasis. A rigid client with a rising temperature shortly after anaesthesia suggests malignant hyperthermia.

Late complications follow their own timeline. Infection after the third day, dehiscence after five to seven days, and deep vein thrombosis within the first two weeks. Matching the timeline to the complication is often the entire question.

Frequently asked questions

Can a nurse obtain informed consent?

No. The provider obtains it. The nurse verifies it is signed, voluntary and understood, and advocates when it is not.

What is the treatment for malignant hyperthermia?

Dantrolene, along with stopping the triggering agent, cooling and supporting ventilation.

What is the most common postop respiratory complication?

Atelectasis. Prevent it with incentive spirometry, deep breathing and early ambulation.

When is a postoperative fever most concerning?

After the third day, which suggests infection rather than the expected early inflammatory response.

What do I verify in the time out before incision?

Client identity, procedure, surgical site, consent, allergies, position, and that any required implants or equipment are present, confirmed by the whole team out loud.

What are the discharge criteria after ambulatory surgery?

Stable vital signs, controlled pain, no nausea, able to ambulate and void, a responsible escort, and instructions understood and in writing.
