The nurse is preparing to administer an IV infusion of nitroprusside to a newly admitted client who is experiencing a hypertensive crisis and has a blood pressure of 250/145mmHg The nurse should recognize that it is a priority to 1. maintain a urine output of at least 30mL/hr 2. decrease the blood pressure to 120/80mmHg 3. maintain the heart rate between 60 and 100/min 4. decrease the mean arterial pressure by no more than 25% initially

Answer

4. decrease the mean arterial pressure by no more than 25\% initially Explanation 1. Identify the Priority in Hypertensive Crisis In a hypertensive crisis, the priority is to reduce blood pressure safely without causing organ damage. The goal is to decrease the mean arterial pressure (MAP) by no more than 25% initially to prevent complications such as ischemia. 2. Calculate the Mean Arterial Pressure (MAP) **Formula:** \text{MAP} = \frac{\text{SBP} + 2(\text{DBP})}{3} Given: SBP = 250 mmHg, DBP = 145 mmHg MAP = \frac{250 + 2(145)}{3} = \frac{250 + 290}{3} = \frac{540}{3} = 180 mmHg 3. Calculate 25% Reduction of MAP 25% of 180 mmHg = 0.25 \times 180 = 45 mmHg New target MAP = 180 - 45 = 135 mmHg

Explanation

1. Identify the Priority in Hypertensive Crisis<br /> In a hypertensive crisis, the priority is to reduce blood pressure safely without causing organ damage. The goal is to decrease the mean arterial pressure (MAP) by no more than 25% initially to prevent complications such as ischemia.<br /><br />2. Calculate the Mean Arterial Pressure (MAP)<br /> **Formula:** $ \text{MAP} = \frac{\text{SBP} + 2(\text{DBP})}{3} $<br /> Given: SBP = 250 mmHg, DBP = 145 mmHg<br /> MAP = $\frac{250 + 2(145)}{3} = \frac{250 + 290}{3} = \frac{540}{3} = 180$ mmHg<br /><br />3. Calculate 25% Reduction of MAP<br /> 25% of 180 mmHg = $0.25 \times 180 = 45$ mmHg<br /> New target MAP = $180 - 45 = 135$ mmHg
