A client has been prescribed a decongestant drug for congestion associated with rhinitis. When teaching the client about this drug, which of the following would the nurse include as a possible adverse reaction?
- A. Decreased pulse rate
- B. Blurred vision
- C. Drowsiness
- D. Dryness of throat
Correct Answer: B
Rationale: The nurse should inform the client that blurred vision is a possible adverse reaction of decongestant drugs. Additionally, an increased and not decreased pulse rate may also be seen. Drowsiness is not seen with decongestant usage. Dryness of the nasal mucosa and not the throat may be seen with decongestant drugs, which are used mostly as topical sprays and drops.
