A patient has been advised to add a topical sympathomimetic decongestant to the regimen of supportive care for a cold. The nurse should instruct the patient to
a. expect the effects to be delayed at least 1 week.
b. limit the use of this agent to 3 to 5 days.
c. continue the agent until nasal stuffiness has resolved.
d. stop using this agent if a fever develops.
ANS: B
Because of the potential for rebound nasal congestion, topical application should be limited to 3 to 5 days.
With topical administration, vasoconstriction is rapid and intense, leading to a quick reduction in nasal congestion.
Rebound nasal congestion can occur if the drug is used for longer than 5 days, therefore the drug should not be continued until the problem resolves.
Topical sympathomimetics are not contraindicated if a patient has a fever.
