A nurse is caring for a client who has been prescribed propranolol for angina. After administering the drug, which of the following would the nurse do?
- A. Ask about relief of symptoms and record responses on the chart
- B. Determine signs of infection in the client
- C. Monitor for sudden decrease in urine output
- D. Monitor for sudden increase in intraocular pressure
Correct Answer: A
Rationale: The nurse should ask about the relief of symptoms and record the responses on the client's chart.

The nurse need not monitor the client for a sudden decrease in urine output and a sudden increase in intraocular pressure for a client receiving propranolol therapy for angina.
