6 Vasodilators and Integrated Cardiovascular Medication Practice Free Online FlashCards

What should be done if a patient took sildenafil earlier today and is prescribed nitroglycerin?

Do not give nitroglycerin; promptly contact the prescriber or emergency team for guidance, especially if chest pain is active.

How should new joint pain, fever, and persistent rash be handled in a patient taking hydralazine?

Promptly report the symptoms to the prescriber for assessment of a possible drug reaction; medication changes should be clinician-directed.

What advice should a patient taking spironolactone and lisinopril receive about potassium salt substitutes?

Do not start it without clinician approval; spironolactone, lisinopril, and potassium-containing salt substitutes can combine to raise potassium.

How can furosemide-related low potassium affect digoxin risk?

Furosemide can lower potassium, increasing the heart’s sensitivity to digoxin.

How can amiodarone affect a patient’s digoxin therapy?

Amiodarone can increase digoxin exposure and intensify slow heart rate or conduction problems; arrange closer monitoring and clinician-directed dose changes.

What is the safe response to planned adenosine use in a patient with second-degree AV block?

Withhold adenosine and immediately alert the treating clinician; it is contraindicated in second- or third-degree AV block without a functioning pacemaker.

What do thirst, muscle cramps, and dizziness on standing suggest during furosemide therapy?

They may indicate excessive diuresis or electrolyte loss; arrange prompt assessment of blood pressure, fluid status, kidney function, and electrolytes.

What serious risk can nitroglycerin and sildenafil pose together?

The combination can cause severe hypotension, fainting, or myocardial ischemia.

What drug reaction can long-term hydralazine use cause?

Hydralazine can cause a lupus-like reaction, sometimes involving the kidneys.

What monitoring is important after starting or increasing spironolactone?

Check potassium after starting or increasing spironolactone and monitor it regularly; kidney function also matters.

What can nausea and yellow-green visual changes suggest in a patient taking digoxin?

Nausea and unusual yellow-green visual changes may occur with digoxin toxicity; low potassium adds concern and warrants prompt clinical assessment.

How can amiodarone affect warfarin therapy?

Amiodarone can increase warfarin’s anticoagulant effect and bleeding risk; closer INR monitoring and clinician-directed dose adjustments may be needed.
