NCLEX-RN® Perioperative Nursing: Preop, Intraop, PACU, and Postop Complication Prevention

Perioperative nursing for the NCLEX-RN®: preoperative checklist and teaching, intraoperative positioning risks, PACU assessment priorities, and early postoperative complication recognition.

The big picture

Perioperative nursing — the care of patients before, during, and after surgery — is tested throughout the NCLEX-RN® under multiple categories. Questions focus on preoperative assessment, intraoperative safety protocols, PACU (post-anesthesia care unit) monitoring, and postoperative complication recognition and prevention. The nurse's role in this setting is as critical as any: errors in the OR suite or recovery room can be immediately life-threatening.

Preoperative phase

Nursing assessment priorities

The preoperative assessment ensures the patient is ready for surgery and alerts the team to conditions that increase operative risk.

Key preoperative assessments:

• Allergies — latex allergy is especially important (latex is used in gloves, equipment tubing, IV ports)
• Current medications: Anticoagulants (warfarin, heparin, aspirin, clopidogrel), insulin, ACE inhibitors, NSAIDs, herbal supplements — many must be stopped pre-op
• Baseline vital signs and SpO₂
• Renal and hepatic function (drug metabolism and clearance)
• Cardiovascular status (EKG, stress test if indicated)
• Respiratory history (smoking, COPD, sleep apnea — OSA patients need CPAP arranged)
• Blood type and crossmatch if blood loss is anticipated
• Pregnancy test for women of childbearing age (anesthesia is teratogenic)
• Mental status and cognitive function (informs consent and post-op monitoring)

Informed consent

• The provider performing the surgery must obtain informed consent — not the nurse
• The nurse's role: witness the signature, verify the patient understands, and notify the provider if the patient has questions or recants
• Consent must be: voluntary, informed, by a competent adult (or authorized surrogate)
• Do not proceed if consent is in question — notify the OR team

NPO (nothing by mouth) requirements

Based on ASA (American Society of Anesthesiologists) NPO guidelines 2023.

NCLEX® key: Medications necessary to maintain a patient's condition (antihypertensives, antiseizure drugs) are typically taken with a sip of water even on the morning of surgery — always verify with the specific provider's orders.

Pre-op teaching priorities

1. Deep breathing and coughing exercises — reduces post-op pneumonia
2. Incentive spirometry — reinforce before surgery so patient knows how to use it in recovery
3. Leg exercises — ankle pumps, quadriceps sets — reduces DVT risk
4. Pain management plan — what to expect; encourage reporting pain
5. Activity restrictions and wound care post-surgery
6. Urinary catheter, tubes, drains — what to expect and why they're there

Latex allergy — priority safety

Signs of latex allergy:

• Contact dermatitis (localized) — delayed; eczema-like
• IgE-mediated systemic reaction — urticaria, rhinitis, asthma, anaphylaxis

If latex allergy is reported or suspected:

• Latex-free environment — use latex-free gloves, equipment, IV ports
• Schedule as the first case of the day (before latex particles contaminate the OR air)
• Alert the entire surgical team and anesthesia

Intraoperative phase

The surgical team

The Universal Protocol (Joint Commission)

The Universal Protocol prevents wrong-site, wrong-patient, and wrong-procedure surgery. It has three components:

1. Pre-procedure verification — confirm correct patient, procedure, site using two identifiers; check consent; confirm relevant documents are present
2. Site marking — the surgeon marks the operative site with a permanent marker ("YES") while the patient is awake
3. Time-out — immediately before the procedure begins, the entire team pauses to confirm: correct patient identity, correct procedure, correct site

Nursing priority: If any team member is uncertain during the time-out, the procedure does not begin until the concern is resolved.

Surgical count

The scrub nurse and circulating nurse count all sponges, sharps, and instruments at least three times:

1. At the start of surgery (baseline count)
2. Before closure of the wound begins
3. Before skin closure

If the count is incorrect, the surgery is halted and the item is located before proceeding. An X-ray may be taken to look for a retained foreign body.

Anesthesia types

PACU (Post-Anesthesia Care Unit)

The PACU is where the patient recovers immediately after surgery. PACU nurses manage patients as they emerge from anesthesia and become physiologically stable.

Priority PACU assessments (ABC order)

1. Airway: Patent? Maintaining own airway? Presence of artificial airway (ETT, LMA, oral airway)?
2. Breathing: Rate, depth, SpO₂; signs of respiratory distress; presence of stridor (laryngospasm)
3. Circulation: BP, HR, rhythm; signs of hemorrhage; peripheral perfusion
4. Mental status: Level of consciousness; ability to follow commands; orientation
5. Temperature: Hypothermia is common post-op; active warming if < 36°C
6. Pain: Assess and manage immediately — pain drives tachycardia and hypertension
7. Surgical site: Dressing status; drains; bleeding

Laryngospasm — PACU emergency

Vocal cords spasm shut after extubation, completely blocking the airway.

Signs: Crowing or high-pitched stridor followed by complete obstruction; SpO₂ rapidly dropping; patient in distress.

Actions:

1. Jaw thrust and positive-pressure oxygen (BVM)
2. Call anesthesia immediately
3. Succinylcholine IV (neuromuscular blocker) if persistent — paralyzes the spasm → re-intubation

Aldrete Score (PACU discharge criteria)

Patients are typically discharged from the PACU when they score ≥ 9 on the Aldrete Score:

Postoperative complications — prevention and recognition

Respiratory: the "Wind" complications

Cardiovascular: DVT/PE

• Occur days 3–7 post-op
• Prevention: SCDs, anticoagulants, early ambulation, leg exercises
• Sudden chest pain + dyspnea + tachycardia post-op = suspect PE until proven otherwise

Wound complications

Urinary retention

First void should occur within 4–8 hours of surgery. Causes: anticholinergic anesthesia effects, pain inhibiting urination, supine position.

If unable to void: Offer privacy; run water; standing or sitting upright to void; bladder scan to confirm retention; straight cath if necessary.

Paralytic ileus

Absence of bowel function post-op — especially common after abdominal surgery.

Signs: Absent bowel sounds, abdominal distension, no flatus or stool.

Management: NPO; NG decompression if vomiting; ambulation; avoid opioids when possible.

First sign of return: Return of flatus (passing gas) — indicates peristalsis is resuming.

Hemorrhage

• Bright red, saturating, rapidly increasing drainage from wound or drains
• Tachycardia and hypotension may follow (late signs — do not wait)
• Immediate: Apply direct pressure; call provider; prepare for blood products; do not remove original dressings (adds more)

Hypothermia

Core temperature < 36°C post-op — very common from cold OR environments, IV fluids, and anesthesia.

Consequences: Impaired coagulation, increased cardiac risk, shivering (increases O₂ consumption), delayed wound healing.

Treatment: Forced-air warming blankets (Bair Hugger), warmed IV fluids, warm blankets.

NCLEX® clinical judgment focus

Perioperative questions often ask about sequence of actions or priority assessment findings.

FAQ

Who is responsible for site marking before surgery?

The surgeon marks the operative site while the patient is awake and can confirm the site. This is part of the Universal Protocol. The nurse does not mark the site but confirms it is marked during the pre-procedure verification and time-out.

What is the first sign of bowel return after surgery?

Return of flatus (passing gas) — this indicates peristalsis has resumed. Bowel sounds may return earlier but are less clinically reliable. Patients can typically begin clear liquids after passing flatus, then advance their diet as tolerated.

Why does a post-op fever on day 1–2 suggest atelectasis rather than infection?

Surgical infections take 3–5 days to develop (bacterial growth and inflammatory response require time). Early fever (first 24–48 hours) is typically caused by atelectasis — collapsed alveoli trigger a mild inflammatory response. Treatment is deep breathing, coughing, and ambulation — not antibiotics.

What is the difference between dehiscence and evisceration?

Dehiscence is separation of wound layers — the wound edges separate. Evisceration is when abdominal organs (usually bowel) protrude through the open wound. Evisceration is the surgical emergency — cover with saline-soaked sterile gauze and call the provider immediately. Never push organs back into the cavity.

When is a spinal anesthetic given and what is the key nursing concern afterward?

Spinal anesthesia is injected into the subarachnoid space, blocking sensation and motor function below the injection level. It is used for lower abdominal, pelvic, and lower extremity surgeries. The key nursing concern is hypotension (sympathetic blockade causes vasodilation → venous pooling → decreased preload). Monitor BP every 5 minutes post-spinal. Do not ambulate the patient until sensation and motor function have returned to baseline.

Key takeaways

• Pre-op: Consent is the provider's responsibility. NPO: 2h clear liquids, 8h full meal. Latex allergy = latex-free environment + first surgical case of the day.
• Intra-op: Universal Protocol = verify + mark + time-out. Correct sponge count is required before closure.
• PACU: Assess ABC in order. Laryngospasm = jaw thrust + BVM + anesthesia stat. Aldrete ≥ 9 for discharge.
• Post-op complications by time: 24h = atelectasis. 3–5 days = DVT/UTI. 5–7 days = wound infection. First flatus = bowel returning.
• Evisceration: Saline-soaked sterile dressing + keep bowel moist + call provider + NPO + knees bent.
