A client is given ephedrine (Efedron) for bronchial asthma. The nurse should ask the client to report which effect of this drug?
1. Drowsiness
2. Palpitations
3. Excessive vomiting
4. Increased appetite
Correct Answer: 2
Rationale 1: Ephedrine, when given orally, is readily absorbed from the GI tract and crosses the blood brain–barrier. It exhibits prominent stimulatory effects in the brain, keeping the patient alert and awake.
Rationale 2: Ephedrine can be used in bronchial asthma because of beta-2 receptor stimulation. It also stimulates beta-1 and alpha receptors, which causes cardiac side effects.
Rationale 3: Ephedrine does not cause excessive vomiting.
Rationale 4: Ephedrine does not cause increased appetite.
