Education on pharmacology is taking place on the nursing unit. The discussion involves the receptor sensitivity of a medication. The presenter asks the nurses to provide an example of de-sensitization

Which of the following responses would be an example of desensitization? a. The synthesis of more receptors
b. Continuous exposure to antagonists
c. Continual exposure to an agonist
d. Antacids used to reduce gastric acid


C
Continual exposure to an agonist would cause the cell to become less responsive or desensitized.
The synthesis of more receptors would create a hypersensitivity reaction.
Continuous exposure to antagonists would also contribute to hypersensitivity.
Antacids used to reduce gastric acid are an example of receptorless drugs.

The patient who had an emergency abdominal surgery looks at his incision on the first postoperative day and says, "I sure hope this doesn't leave much of a scar. Is there some type of medicine or ointment I can put on it?"

What should the nurse consider prior to responding to that comment? 1. This incision will heal by primary intention and will probably leave only a hairline scar. 2. This incision will fill in with granulation tissue and leave a moderately big scar despite any medication applied. 3. This incision was done in an emergent fashion but continuous application of steroid creams will prevent scarring. 4. This incision will have to be reclosed later and will leave a large scar unless a topical antibiotic is used continuously.
