1. A client is being cared for by a nurse 2 hours after admission. The client has an SaO2 of 91%, exhibits audible wheezes, and is using accessory muscles when breathing. Which of the following classes of medication should the nurse expect to administer?
- A. Antibiotic
- B. Beta-blocker
- C. Antiviral
- D. Beta2 agonist
Correct answer: Beta2 agonist
Rationale: The client's presentation with an SaO2 of 91%, audible wheezes, and use of accessory muscles indicates respiratory distress, likely due to bronchoconstriction. Beta2 agonists are the appropriate class of medications to administer in this situation as they act as bronchodilators, helping to relieve the bronchoconstriction and improve airflow to the lungs. Antibiotics, beta-blockers, and antivirals are not indicated for this client's respiratory distress symptoms.
