A 78-kg patient with septic shock has a urine output of 30 mL/hr for the past 3 hours. The pulse rate is 120/minute and the central venous pressure and pulmonary artery wed pressure are low. Which order by the health care provider will the nurse question?

Administer hydrocortisone (Solu-Cortef) 100 mg IV.

Give PRN furosemide (Lasix) 40 mg IV.

Increase normal saline infusion to 250 mL/hr.

Titrate norepinephrine (Levophed) to keep systolic BP >90 mm Hg.

Answer and Explanation

The Correct Answer is C

In septic shock, one of the key goals of management is to restore and maintain adequate intravascular volume. However, in this case, the patient's urine output is low (30 mL/hr for the past 3 hours), suggesting inadequate renal perfusion and potential fluid overload.
Administering additional normal saline at an increased rate (250 mL/hr) without addressing the low urine output could potentially exacerbate fluid overload and further compromise the patient's condition.
A. Administer hydrocortisone (Solu-Cortef) 100 mg IV in (option A) is incorrect because: Hydrocortisone is commonly used in septic shock to help stabilize blood pressure and modulate the inflammatory response.
B. Giving PRN furosemide (Lasix) 40 mg IV in (option B) is incorrect because Furosemide, a loop diuretic, can be administered as needed to address fluid overload or to increase urine output if there is evidence of volume overload.
D. Titrate norepinephrine (Levophed) to keep systolic BP >90 mm Hg in (option D) is incorrect because: Norepinephrine is a vasopressor commonly used in septic shock to increase systemic vascular resistance and maintain adequate blood pressure.

Correct Answer is ["9000"]

Explanation

4 mL × body weight in kg × percentage of burn = total fluid volume for the first 24 hours Then, divide the total fluid volume by 2 to determine the fluid volume for the first 8 hours.

In this case, the patient weighs 90 kg and has a 50% burn injury.

4 mL × 90 kg × 50% = 18,000 mL (total fluid volume for 24 hours)

18,000 mL / 2 = 9,000 mL (fluid volume for the first 8 hours)

Therefore, the nurse would infuse the intravenous fluid resuscitation at a rate of 9,000 mL over the first 8 hours.

A. It causes vasoconstriction and increased MAP. B. Lower blood volume lowers MAP. C. It raises cardiac output and MAP. D. There is no direct correlation to MAP.

Correct Answer is B

Explanation

Mean arterial pressure (MAP) is a measure of the average pressure within the arteries during one cardiac cycle. It represents the perfusion pressure that drives blood flow to organs and tissues. MAP is calculated using the formula:
MAP = Diastolic blood pressure + 1/3 (Systolic blood pressure - Diastolic blood pressure)
Blood loss, particularly in cases of significant hemorrhage, leads to a decrease in blood volume. When blood volume decreases, there is less circulating blood available to generate pressure within the arterial system. This reduction in blood volume results in decreased MAP.
Therefore, in the case of massive blood loss after trauma, the student can correlate it with a lower blood volume, which in turn leads to a lower MAP. The decrease in blood volume reduces the perfusion pressure, compromising organ and tissue perfusion
A. It causes vasoconstriction and increased MAP in (option A) is incorrect because: While vasoconstriction can occur as a compensatory mechanism to maintain blood pressure, it does not necessarily lead to an increased MAP in the context of significant blood loss.
C. It raises cardiac output and MAP in (option C) is incorrect because Blood loss typically leads to a reduction in cardiac output due to decreased blood volume. Therefore, it does not raise cardiac output and MAP.
D. There is no direct correlation to MAP in (option D) is incorrect because: There is indeed a direct correlation between blood loss and MAP. As blood volume decreases, MAP decreases as well.
Therefore, the correct correlation between blood loss and MAP is that lower blood volume lowers MAP.
