Airway resistance is increased by:

A 7-year-old child was playing near a large pile of sand when the ground underneath him collapsed. You can hear him crying and asking for his mother. Until the technical rescue team arrives at the scene, you should:

A) get as close to the edge of the trench as possible and attempt to visualize the child. B) maintain verbal contact with the child, but avoid going near the edge of the trench. C) throw the child a rope and ask him to tie it around his waist so you can pull him out. D) use several long backboards as shoring to decrease the risk of a secondary collapse.

After 20 minutes of performing CPR on a 65-year-old female with end-stage multiple sclerosis, your medical director orders you to stop resuscitation and inform the family that the patient has died. The family members are upset and crying. You notice the patient's daughter holding her hand. Your immediate response would be:

A) "It's okay to hold her hand, but you should really use gloves like we do." B) "It's important not to touch her since she may be infectious from her disease." C) "I know that you are upset, but it is best not to touch her since she just passed." D) "It's okay to hold her hand."
