Answer to Question 1

B
Zanamivir is an inhalation drug. When a patient also takes a bronchodilator for asthma, chronic obstructive pulmonary disease, or any other airway problem, the manufacturer recommends using the bronchodilator at least 5 minutes before zanamivir to ensure a wider airway and improved inhalation of the antiviral drug.

Answer to Question 2

C
Respiratory depression (decreased drive for breathing) is a life-threatening adverse effect that can occur with several antiemetic drugs, including promethazine. The nurse must be sure to monitor the patient's respiratory rate after administering this drug and report a decrease in respi-ratory rate to the prescriber. The drug should be held because a respiratory rate of 8 breaths per minute is very low.
