A client taking lisinopril has persistent blood pressure readings near 168/96 mm Hg and asks about using oral pseudoephedrine for nasal congestion. Which response should the nurse give?
1"Pseudoephedrine acts inside the nose, so it cannot affect blood pressure or heart rate."
2"Take pseudoephedrine with an extra lisinopril dose to prevent a medication interaction."
3"Hold lisinopril while taking pseudoephedrine so the decongestant can work more effectively."
4"Do not start pseudoephedrine without prescriber review; it can raise blood pressure. Use saline meanwhile."✓ Correct answer
Explanation
Pseudoephedrine is a systemic sympathomimetic decongestant that can increase blood pressure and heart rate. Product labeling directs clients with hypertension or heart disease to consult a clinician before use. With markedly elevated readings despite lisinopril, the client should not self-start pseudoephedrine and should seek a safer congestion plan. The client should not change the lisinopril dose or schedule independently.
Clinical reasoning Oral pseudoephedrine constricts blood vessels beyond the nasal mucosa. That systemic adrenergic action can oppose blood-pressure control and add cardiovascular stress.
Decision rule Screen nonprescription decongestants for sympathomimetics. In poorly controlled hypertension, pause self-treatment, involve the prescriber or pharmacist, and use a non-systemic measure while awaiting guidance.
Scenario 58-year-old male with controlled hypertension on lisinopril asks if he can take pseudoephedrine 60 mg PO q6h for cold-related nasal congestion.
Pseudoephedrine — An oral sympathomimetic decongestant that reduces nasal swelling through vasoconstriction and can increase cardiovascular stimulation.
Uncontrolled hypertension — Blood pressure that remains substantially above target despite current management and requires clinical reassessment.
