The nurse is educating an older adult client diagnosed with rhinosinusitis in an outpatient clinic about the prescribed topical
oxymetazoline. The client has a history of hypertension and coronary artery disease. Which statement made by the client establishes the need for further clarification?A. "I will rinse the spray tip off after each use.B. "I will blow my nose before using the nasal spray.C. "I can take over-the-counter pseudoephedrine, too.D. "The drug is used no longer than 3 days."
<u>C."I can take over-the-counter pseudoephedrine, too."</u>
Explanation:
The nurse should clarify the statement that the patient made regarding taking pseudoephedrine OTC in addition to the nasal spray that is prescribed. The patient has a history of hypertension and coronary artery disease, both contraindications for the adrenergic drug, pseudoephedrine. Pseudoephedrine will increase blood pressure, pulse, and cause heart muscle irritability. Topical decongestants are chosen for patients with cardiovascular disease for this reason. The other statements are all correct. Blowing the nose helps to clear the passage of the drug, so it is more effective. The spray tip should be rinsed off after each use. Rebound congestion can be caused by drug if used more often than recommended on the package or longer than 3 days.
They are both highly selective,most of the time what binds to them. Think of it as a lock and key, if the key fits the lock and it turns then it does what it needs.
