Final answer:
For an unresponsive person with a blocked airway, one should give chest compressions and look for an object between compressions and breaths; the correct answer is D) Both A and B.
Step-by-step explanation:
The appropriate care for a person who is unresponsive and has a blocked airway involves giving chest compressions and looking for an object between compressions and breaths. According to current standards, chest compressions should be at least 5 cm deep at a rate of 100 compressions per minute. If a person is choking, it is essential to clear the airway using the Heimlich maneuver and, if the obstruction is not cleared, seeking emergency medical help is crucial.
The answer to the student's question, which involves care for a person who is unresponsive with a blocked airway, is D) Both A and B. This includes giving chest compressions and looking for an object between compressions and breaths. Abdominal thrusts or the Heimlich maneuver may be appropriate for responsive individuals but are not specified for unresponsive cases with a blocked airway.
