Consent not understood → notify
Abnormal labs / infection signs
📚 Preoperative Care — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Preoperative care is everything done to physically and psychologically prepare a patient for surgery, from scheduling to transfer to the OR. The goals are to confirm informed consent, reduce surgical risk, and prevent complications such as aspiration, infection, and wrong-site surgery. Key concerns include NPO status, baseline vitals and labs, allergy verification, and a complete preoperative checklist.
🔑
Key points
Understand these first
Informed consent must be signed before any sedation is given and must be obtained by the surgeon, not the nurse; the nurse witnesses the signature and confirms understanding.
Patients are typically NPO 6-8 hours for solids and about 2 hours for clear liquids to reduce aspiration risk under anesthesia.
A surgical time-out (correct patient, correct procedure, correct site) is performed in the OR to prevent wrong-site/wrong-patient surgery.
Allergies, current medications, anticoagulants, and herbal supplements must be documented because many increase bleeding or interact with anesthesia.
Baseline vital signs, height/weight, and labs (CBC, electrolytes, coagulation, type and crossmatch) establish a comparison point for the postoperative period.
Removal of dentures, jewelry, contact lenses, nail polish, and prostheses, plus voiding before transfer, are standard safety steps.
✅
Nursing priorities
What to do, in order
Verify a properly signed and witnessed informed consent is in the chart before giving any preoperative sedative.
Confirm and reinforce NPO status; report any recent intake immediately as it may delay or cancel surgery.
Complete the preoperative checklist: ID band, allergy band, vitals, labs, consent, site marking, and removal of valuables/prostheses.
Hold or administer ordered medications appropriately (e.g., insulin and anticoagulant adjustments per provider orders).
Provide teaching on coughing, deep breathing, incentive spirometer, leg exercises, and pain control to lower postoperative complications.
🚩
Red flags — report now
Escalate immediately
Patient cannot describe the planned procedure or expresses misunderstanding; stop and notify the surgeon before proceeding.
Patient ate or drank within the NPO window; report immediately as aspiration risk may require postponement.
Consent signed after a sedative was already given is invalid; notify the provider and do not proceed.
New or undocumented allergy (especially latex or anesthesia agents) must be reported and banded before surgery.
🧪
Labs & values
Numbers to know
Hemoglobin: 12-18 g/dL
Platelets: 150,000-400,000/mcL
INR: 0.8-1.1 (elevated increases bleeding risk)
Potassium: 3.5-5.0 mEq/L
🗣️
Patient teaching
What patients must know
Demonstrate splinting the incision while coughing and deep breathing and using the incentive spirometer 10 times each hour while awake.
Explain that early ambulation and leg exercises prevent blood clots and pneumonia.
Report all medications, supplements, and allergies, and follow NPO instructions exactly to keep surgery on schedule.
❓ Preoperative Care: NCLEX FAQs
What are the priority nursing interventions for Preoperative Care?
Verify a properly signed and witnessed informed consent is in the chart before giving any preoperative sedative. Confirm and reinforce NPO status; report any recent intake immediately as it may delay or cancel surgery. Complete the preoperative checklist: ID band, allergy band, vitals, labs, consent, site marking, and removal of valuables/prostheses. Hold or administer ordered medications appropriately (e.g., insulin and anticoagulant adjustments per provider orders).
What are the warning signs of Preoperative Care a nurse must report?
Patient cannot describe the planned procedure or expresses misunderstanding; stop and notify the surgeon before proceeding. Patient ate or drank within the NPO window; report immediately as aspiration risk may require postponement. Consent signed after a sedative was already given is invalid; notify the provider and do not proceed. New or undocumented allergy (especially latex or anesthesia agents) must be reported and banded before surgery.
