An older postoperative patient is given an antiemetic for nausea. Which manifestation indicates to the nurse that this patient is experiencing a possible reaction to the medication?
1. involuntary muscle movements
2. confusion
3. dry mouth
4. breakthrough vomiting
Correct Answer: 1
Antiemetics, such as metoclopramide (Reglan) and droperidol (Inapsine), can have tranquilizing effects as well as cause an extrapyramidal reaction. The patient would demonstrate involuntary movements, muscle tone changes, and abnormal posturing. Elderly patients may also experience drowsiness, which reduces orientation, after being given antiemetics. A dry mouth may be experienced as a result of having been or currently being unable to have oral intake. Breakthrough vomiting is not an indication of an adverse reaction.
