Answer to Question 1

B
Feedback:
Macrolide antibiotics can cause severe auditory nerve damage so the nurse would question administration of this drug to the child with hearing loss because another antibiotic may be indicated to preserve remaining hearing. This drug is not contraindicated in older adults, although a lower dosage may be indicated. It may safely be given in pregnancy and after myocardial infarction.

Answer to Question 2

D
Feedback:
Surfactant is a lipoprotein that decreases the surface tension in the sac and prevents alveolar collapse. ATP, histamine, and serotonin are released from mast cells throughout the airway to ensure a quick and intense inflammatory reaction to any cell injury, which may lead to a respiratory infection.
