A patient is prescribed sublingual nitroglycerin for angina. What instruction is correct if pain persists?
Answer: Take up to 3 tablets 5 minutes apart, then call 911 if unrelieved
Up to 3 doses 5 minutes apart are allowed; unrelieved pain requires emergency care.
Which common side effect should the nurse expect with nitroglycerin?
Answer: Throbbing headache
Vasodilation from nitroglycerin commonly causes headache.
Nitroglycerin is contraindicated with which class of erectile dysfunction drugs due to severe hypotension?
Answer: Phosphodiesterase inhibitors (sildenafil)
Combining nitrates with sildenafil causes dangerous, potentially fatal hypotension.
How should a patient store sublingual nitroglycerin tablets to maintain potency?
Answer: In the original dark glass bottle, away from light and heat
Nitroglycerin degrades with light and heat, so the dark glass container preserves potency.
When applying a nitroglycerin transdermal patch, the nurse should do what to prevent tolerance?
Answer: Allow a nitrate-free interval of 10–12 hours daily
A daily nitrate-free interval prevents the development of tolerance.
A patient feels dizzy after taking sublingual nitroglycerin. What is the priority nursing action?
Answer: Have the patient sit or lie down
Sitting or lying down prevents falls from nitroglycerin-induced hypotension.
What sensation indicates a sublingual nitroglycerin tablet is still potent?
Answer: A tingling or fizzing under the tongue
A tingling or fizzing sensation suggests the tablet retains potency.
