🏥 Post-Anesthesia Unit — Vital Signs

✅ Answer: (B) 15 minutes

📖 What is PACU?

PACU = Post-Anesthesia Care Unit

Post = After
Anesthesia = Medication used to produce loss of sensation or consciousness
Care Unit = Area where patients are closely monitored

👉 The PACU is the recovery area where a patient is monitored after anesthesia until the effects of anesthesia wear off and the patient becomes stable.

🩺 Why is Option (B) Correct?

After anesthesia, the patient is at risk for complications such as:

• ✔ Airway obstruction
• ✔ Respiratory depression
• ✔ Hypotension or hypertension
• ✔ Cardiac dysrhythmias
• ✔ Decreased level of consciousness

👉 Therefore, frequent monitoring of vital signs is essential during the immediate recovery period.

For this exam question, the expected answer is every 15 minutes.

📖 What are Vital Signs?

Vital = Essential for life.
Signs = Measurable indicators of the body’s condition.

The main vital signs include:

• 🌡️ Temperature
• ❤️ Pulse/Heart rate
• 🫁 Respiratory rate
• 🩸 Blood pressure
• 🫁 Oxygen saturation (SpO₂)

❌ Why Other Options Are Less Appropriate?

(A) 5 minutes
❌ This is more frequent than the usual interval expected in this question and may be used when a patient is particularly unstable or requires very close monitoring.

(B) 15 minutes
✅ Correct. Frequent 15-minute observations are commonly used during the immediate PACU recovery period.

(C) 30 minutes
❌ Too long for the initial recovery period when complications from anesthesia can develop rapidly.

(D) 60 minutes
❌ Too infrequent for a newly transferred post-anesthesia patient.

📝 What Should the Nurse Assess?

📌 Exam Tip: For questions asking about routine vital-sign monitoring immediately after transfer to the PACU, remember 15 minutes. Actual monitoring frequency may be individualized according to the patient’s condition and facility protocol.
