Answer to Question 1
Correct Answer: 1
Rationale 1: The respiratory system offers a rapid and efficient mechanism for delivering drugs. The enormous surface area of the bronchioles and alveoli, and the rich blood supply to these areas, results in an almost instantaneous onset of action for inhaled substances.
Rationale 2: Albuterol (Proventil) can be given orally (PO), but has a faster onset of action if inhaled.
Rationale 3: Inhaled medications also produce side effects.
Rationale 4: Oral medications are effective with some symptoms of respiratory disorders, but inhaled medications work faster.
Answer to Question 2
Correct Answer: 1,3,4,5
Rationale 1: The nasal passages should be cleared by blowing the nose immediately before the medication is administered.
Rationale 2: Fluids should be increased, but it is not necessary to drink a glass of water immediately before using the spray.
Rationale 3: Nasal decongestant sprays should not be used for more that 35 days.
Rationale 4: The client should wait 510 minutes between administering different nasal sprays to allow the first medication some time to work before the second one is used.
Rationale 5: Excess spray should not be swallowed as systemic effects may occur.
