Pharmacology and the Nursing Process by Linda Lane Lilley: Practice Exam

What must be observed in a patient overdosing on a beta agonist?

1. Immediate cessation of all medications

2. Administration of a beta blocker under observation

3. High doses of aspirin

4. Administration of an alpha agonist

The correct answer is: Administration of a beta blocker under observation

An overdose of a beta agonist can result in dangerously high blood pressure, increased heart rate, and constriction of blood vessels. Administering a beta blocker (a medication that blocks the effects of beta agonists) would help to counteract these symptoms and bring the patient's vital signs back to a safer level. It is important to administer this medication under observation to ensure it is effective and to monitor the patient for any potential adverse reactions. Options A, C, and D are incorrect because they would not directly counteract the effects of a beta agonist overdose. In fact, option A could potentially worsen the situation by abruptly stopping necessary medications. Aspirin (option C) is not indicated for beta agonist overdose and administration of an alpha agonist (option D) could further increase blood pressure and heart rate.
