Only give Nitro if SBP is greater than which value and no lower than how many mmHg below baseline?

Only give Nitro if SBP is greater than which value and no lower than how many mmHg below baseline?

• A. 100 mmHg; 20 mmHg below baseline
• B. 90 mmHg; 30 mmHg below baseline
• C. 110 mmHg; 40 mmHg below baseline
• D. 80 mmHg; 20 mmHg below baseline

Answer: (B)

Nitro can help relieve chest pain from ischemia, but it lowers blood pressure. To avoid dangerous hypotension, it’s given only when the patient’s current systolic blood pressure is above 90 mmHg and the drop from their baseline BP is not greater than about 30 mmHg. So the safe condition is an SBP greater than 90 mmHg with no more than a 30 mmHg fall from baseline. If either threshold isn’t met—SBP at or below 90 mmHg, or a drop exceeding 30 mmHg from baseline—nitro should not be given. This approach helps balance relief of ischemia with maintaining adequate perfusion, and remember to consider right ventricular infarction and drug interactions that can affect BP.
