The nurse is administering an albuterol (Ventolin) inhaler to a client with asthma. The absorption of the medication will occur in what manner?
 
  1. Very slowly, since the airways are constricted
  2. Over a 2- to 3-hour period
  3. In a slow, steady fashion
  4. Very rapidly

Question 2

The nurse recognizes that adding a vasoconstrictor to a local anesthetic agent will have which effect on absorption of the anesthetic agent?
 
  1. It will increase blood flow to the area.
  2. It will help to eliminate the drug sooner.
  3. It will produce a more localized effect.
  4. It will slow absorption of the agent.

Answer to Question 1

Correct Answer: 4
Rationale 1: Even though some airway constriction might be present, the airway membranes are very thin, and will absorb the medication.
Rationale 2: It will not take 2 to 3 hours for absorption to occur.
Rationale 3: Absorption will not occur in a slow, steady fashion.
Rationale 4: Drugs given via inhalation produce a rapid response, since the membrane separating the drug from the bloodstream is very thin and absorption occurs readily.
Global Rationale: Drugs given via inhalation produce a rapid response, since the membrane separating the drug from the bloodstream is very thin and absorption occurs readily. Even though some airway constriction might be present, the airway membranes are very thin, and will absorb the medication. It will not take 2 to 3 hours for absorption to occur. Absorption will not occur in a slow, steady fashion.

Answer to Question 2

Correct Answer: 4
Rationale 1: Vasoconstriction will reduce blood flow to the area.
Rationale 2: Vasoconstrictors will not alter the anesthetics agent's rate of elimination.
Rationale 3: It will not produce a more localized effect.
Rationale 4: Vasoconstriction reduces blood flow to the site and slows absorption of the agent.
Global Rationale: Vasoconstriction reduces blood flow to the site and slows absorption of the agent. Vasoconstriction will reduce blood flow to the area, will not alter the anesthetic agent's rate of elimination, nor will it produce a more localized effect.
