Hard

A patient is found unconscious in a closed room with a running charcoal heater. The pulse oximeter reads 98%, but the patient has headache, confusion and nausea. Which intervention should the nurse prioritise?

Correct answer: A. Administer high-concentration oxygen and arrange urgent transfer

  • A. Administer high-concentration oxygen and arrange urgent transfer
  • B. Remove oxygen and repeat pulse oximetry after fifteen minutes
  • C. Give oral glucose and observe for improvement
  • D. Place the patient in a warm room and encourage rest

Explanation

Carbon monoxide can cause serious tissue hypoxia while producing a misleadingly normal pulse oximeter reading. High-concentration oxygen helps remove carbon monoxide from haemoglobin, while observation alone delays definitive care.
