Nitroglycerin nursing considerations
Nitroglycerin's nursing considerations start with having the patient sit or lie down before taking it, because it drops the blood pressure. For sublingual tablets, teach the call-911 rule: if chest pain is not relieved five minutes after the first tablet, call 911, taking up to three tablets five minutes apart. Never combine it with erectile-dysfunction drugs.
What nitroglycerin does, and why the NCLEX tests it
Nitroglycerin is a nitrate that dilates veins more than arteries, lowering preload and the heart's oxygen demand to relieve angina. It also dilates the coronary arteries. The exam tests the sit-down-first safety step, the sublingual dosing rule, and the deadly interaction with ED drugs.
Key nursing considerations for nitroglycerin
Nitroglycerin lowers blood pressure and can cause dizziness or fainting, so the patient should be seated.
For unrelieved chest pain, take one tablet, and if pain is not relieved or is worse after five minutes, call 911; up to three tablets total, five minutes apart.
A throbbing headache from vasodilation is common and means the drug is working; treat it with acetaminophen. It is not a reason to stop.
Never take a nitrate with sildenafil, tadalafil, or vardenafil; the combination causes life-threatening low blood pressure.
Store tablets in the original dark glass bottle away from light and heat, and remove a transdermal patch for 10 to 12 hours daily to prevent tolerance.
How the NCLEX turns nitroglycerin into a question
Report severe low blood pressure or fainting; a headache is expected and is a trap answer for report.
Priority have the patient sit or lie down, assess blood pressure, and for ongoing chest pain follow the call-911 rule.
Lab blood pressure; hold IV nitroglycerin and notify for hypotension.
Teach sit down before taking it, call 911 if the pain is not relieved after the first tablet, store tablets in the dark glass bottle, and never use erectile-dysfunction drugs with it.
A patient about to take sublingual nitroglycerin while standing. The correct action is to have them sit or lie down first.

How do you take sublingual nitroglycerin for chest pain?
Sit or lie down, place one tablet under the tongue, and if the pain is not relieved or worsens after five minutes, call 911. You may take up to three tablets, five minutes apart.
