Question 2
You have been called to a home for severe respiratory distress. You arrive to find a hysterical young woman who says she had been asked to watch her nephew for a little while when his mother went out. He has a tracheostomy, and she says he is having a hard time breathing. She has no idea how to care for him because the mother left no instructions. You assess the child and find a nearly totally mucus-plugged trach tube. What should you do?
A) Place the child on O2 via a trach mask. Do not attempt to suction, because doing so may force more mucus into the lungs. Transport immediately.
B) Call for orders to suction the trach tube.
C) Suction the tube and, if available, replace it with a clean, unobstructed one. Give the young woman guidance as to basic trach care.
D) Call the police and tell them the child has been put in a dangerous situation. Place the child on a nonrebreather mask and transport immediately.
