Before We Start
Why pre-op teaching happens before, not after, surgery
A significant part of preoperative nursing care is teaching skills the patient will need after surgery — deep breathing, coughing technique, incentive spirometer use — while the patient is still calm, pain-free, and able to focus and learn. Trying to teach these same skills for the first time immediately post-op, when the patient is groggy, in pain, and possibly nauseated, is far less effective. This is the core logic behind front-loading pre-op teaching.
💡 The Nurse's Role in Consent
The nurse verifies that informed consent has been signed and confirms the patient can accurately describe the planned procedure in their own words — a sign of true understanding, not just a signature. Obtaining informed consent itself (explaining risks, benefits, and alternatives) is the surgeon's responsibility, not the nurse's. If a patient expresses confusion or seems not to fully understand the procedure, the nurse notifies the surgeon before proceeding — consent isn't valid without genuine understanding.
The Pre-Op Checklist
What gets confirmed and taught
Respiratory Teaching
Deep breathing, coughing, and the incentive spirometer
General anesthesia and post-op pain both reduce a patient's normal deep breathing, increasing the risk of atelectasis (partial lung collapse) and pneumonia after surgery. The nurse teaches deep breathing exercises, effective coughing technique (often with a pillow splinted against an abdominal incision to reduce pain), and proper incentive spirometer use — all skills the patient will be expected to perform regularly in the postoperative period.
Physical Preparation
NPO status, removal of items, and voiding
NPO status is confirmed per facility policy to reduce aspiration risk during anesthesia. Jewelry, dentures, hairpins, and makeup are removed. Nail polish (especially dark colors) and artificial nails are removed because they can interfere with accurate pulse oximetry readings during and after surgery. The patient voids before transport to the OR to keep the bladder empty during the procedure.
🩺 "Pulse ox reads light through the nail bed — dark polish or acrylics can throw the reading off, which is why it's a pre-op removal item, not just a cosmetic ask."
Surgical Site Verification
The Universal Protocol
Per the Joint Commission's Universal Protocol, the surgical site is marked and verified before the procedure — confirming the correct patient, correct procedure, and correct site (critical for any procedure involving laterality, like a specific limb or side of the body). This is a multi-step safety check, not a single signature, and involves the patient/family confirming the site whenever possible.
🏥 Clinical Scenario
While completing pre-op teaching, a patient scheduled for a hip replacement mentions they thought the surgery was on the other hip.
Nurse Action
The nurse stops and does not proceed with further pre-op preparation until this discrepancy is resolved — a mismatch about which side is being operated on is a critical safety concern, not a minor miscommunication. The surgical team and surgeon are notified immediately to clarify and confirm the correct site before moving forward.
📌 NCLEX Application
These questions test the nurse's specific role and priority actions:
Consent role: "What is the nurse's role regarding informed consent for surgery?" → Witness the patient's signature and confirm understanding — not obtain the consent itself, which is the surgeon's responsibility.
Timing of teaching: "Why is incentive spirometer use taught before surgery rather than after?" → The patient can learn more effectively while pain-free and alert, and will need to use the skill immediately post-op.
Removal item: "Why is nail polish removed before surgery?" → It can interfere with accurate pulse oximetry readings.
⚠️ The Trap — Treating Consent Verification as a Formality
It's easy to treat the consent form check as simply confirming a signature exists. If a patient can't accurately describe what procedure they're having, or expresses confusion or doubt, that's a signal that true informed consent may not be present — regardless of the signature on the page. The safeguard: always ask the patient to describe the planned procedure in their own words, and escalate any mismatch or confusion to the surgeon before proceeding.
✓ Quick Self-Test
1. Whose responsibility is it to obtain informed consent, and what is the nurse's role?
2. Why is incentive spirometer teaching done before surgery rather than after?
3. Why is nail polish removed before surgery?
Answers:
1. The surgeon obtains consent; the nurse witnesses the signature and confirms the patient's understanding.
2. The patient can learn more effectively while pain-free and alert, and will need the skill immediately after surgery.
3. It can interfere with accurate pulse oximetry readings.
