A patient develops dizziness after nitroglycerin; what should you assess next?

• A. Blood pressure; ensure SBP remains adequate and patient is stable.
• B. Respiratory rate only.
• C. Temperature.
• D. Urine output.

Answer: (A)

Dizziness after nitroglycerin often points to a drop in blood pressure from the medication’s vasodilating effect, which can reduce cerebral perfusion. The most important next assessment is blood pressure to confirm that the systolic pressure remains adequate and that the patient is stable. If the BP has fallen or the patient becomes hypotensive, you’d manage accordingly (e.g., stop nitro and support perfusion). Other measurements like respiratory rate, temperature, or urine output don’t directly reveal nitroglycerin-induced hemodynamic instability in this acute moment, so they’re less critical for guiding immediate management.
