A positive feedback is an initial stimulus that produces a response that reinforces that stimulus

At 1540 hours, you respond to a call in a maternity store at a shopping mall, where you find a woman in labor. The physical exam reveals that the baby's head is crowning, and the mother says that she needs to push. When you deliver the infant, it is covered with a greenish-black material. The infant's respirations are gasping and are NOT moving air. You should:

a. position the infant head down and rub its back to stimulate breathing. b. begin immediate ventilation with oxygen using the bag-valve mask. c. intubate the trachea and apply suction to the ET tube to remove any foreign material from the lower airway. d. give blow-by oxygen and transport immediately.

As the AEMT responsible for triage at a motor-vehicle collision, you find a patient who is breathing 18 times per minute and has a radial pulse. Which one of the following should you do next?

A) Check the blood pressure. B) Move the patient to the treatment area. C) Check the mental status. D) Place a yellow tag on the patient.
