Question 89Safety & Environmental - QMED

The correct answer is D) applying his mouth tightly over the victim's mouth. During mouth-to-mouth resuscitation, the rescuer needs to create an airtight seal to effectively deliver breaths to the victim. Applying the rescuer's mouth tightly over the victim's mouth is the best way to achieve this airtight seal. Pinching the victim's nostrils also helps prevent air from escaping and ensures the breaths go into the lungs. The other options are incorrect because they do not create the necessary airtight seal. Holding the jaw down firmly or keeping the head elevated may not properly seal the mouth, and cupping a hand around the patient's mouth would not provide a tight enough seal.
