Question

A patient’s systolic blood pressure drops from 210 mmHg to 100 mmHg in 10 minutes after they took nitroglycerin. Calculate the patient’s rate of change in blood pressure in a min; calculate in a second.

a) -11 mmHg/min and -0.18 mmHg/sec


b) 10 mmHg/min and 0.167 mmHg/sec


c) 11 and 0.18


d) 10 mmHg/min

Answer 1

The patient's rate of change in blood pressure is -11 mmHg/min and -0.18 mmHg/sec.

Step-by-step explanation:

To calculate the patient's rate of change in blood pressure, we use the formula:

Rate of change = (final pressure - initial pressure) / time

Plugging in the values, we get:

Rate of change = (100 mmHg - 210 mmHg) / 10 minutes = -11 mmHg/min

To convert this rate to seconds, we divide by 60:

Rate of change = -11 mmHg/min / 60 sec = -0.18 mmHg/sec
