Falling oxygen saturation, a respiratory rate under 12, or loss of response to voice signals oversedation; stop, support the airway, and give a reversal agent.
Before you read
Test yourself first: 3 questions
Question 1 of 3
A nurse is preparing a client for surgery and notes the client has nail polish and a wedding ring on. Which is the most appropriate nursing action?
Answer: A. Nail polish can interfere with pulse oximetry readings and should be removed, and rings should be removed or secured to prevent injury, swelling complications, and the risk of burns if electrocautery is used. Removing or taping the ring and removing polish supports safe monitoring.
Question 2 of 3
A nurse is caring for a client immediately after a thrombolytic infusion for ischemic stroke. Which assessment finding requires the most urgent intervention?
Answer: B. Sudden severe headache, decreasing level of consciousness, or new neurologic deficit after tPA suggests intracranial hemorrhage, the most dangerous complication of thrombolysis, and requires immediate action.
Question 3 of 3
The nurse is monitoring a newborn for cold stress. Which physiologic consequence places the cold-stressed newborn at greatest immediate risk?
Answer: B. A cold-stressed newborn increases metabolic rate and burns brown fat for nonshivering thermogenesis, which raises oxygen and glucose consumption. This leads to hypoglycemia and can produce metabolic acidosis and respiratory distress. Preventing heat loss is therefore essential to neonatal stability.
Keep the streak going with more questions like these, each with a full rationale.
What is conscious sedation monitoring?
The nurse continuously monitors airway, breathing, and circulation because oversedation can rapidly progress to respiratory depression. A dedicated nurse whose only job is monitoring the patient is required. Reversal agents and resuscitation equipment must be immediately available.
Key points to remember
- The patient maintains a patent airway and responds purposefully to verbal commands during proper moderate sedation.
- Continuous monitoring of oxygen saturation, respiratory rate, heart rate, blood pressure, and level of consciousness is required.
- Capnography detects hypoventilation earlier than pulse oximetry alone.
- Common agents are midazolam and fentanyl; reversal agents are flumazenil for benzodiazepines and naloxone for opioids.
- A separate qualified nurse must monitor the patient and not assist with the procedure.
- Emergency airway equipment, oxygen, suction, and reversal drugs must be at the bedside.
Nursing priorities
- Verify NPO status, baseline vital signs, allergies, and a signed consent before sedation.
- Continuously monitor airway, oxygen saturation, capnography, vital signs, and responsiveness.
- Keep oxygen, suction, an Ambu bag, and reversal agents immediately available.
- Have a dedicated nurse focused solely on patient monitoring during the procedure.
- Continue monitoring during recovery until the patient meets discharge criteria and is at baseline.
Labs & values
Patient teaching
- You will be drowsy and relaxed but should still be able to respond to our voices.
- Do not eat or drink before the procedure as instructed to keep you safe.
- Arrange for someone to drive you home, and do not drive or make important decisions for 24 hours.
Red flags: report now
- Falling oxygen saturation, a respiratory rate under 12, or loss of response to voice signals oversedation; stop, support the airway, and give a reversal agent.
- Never leave a sedated patient unmonitored, and never have the monitoring nurse also assist the procedure.
- Loss of protective airway reflexes means sedation has gone too deep and requires immediate intervention.
