Ordered: Dopamine2mcg/kg/min In Stock: 200mg in 250mL Saline Patients weight: 60kg What rate would you set the pump to deliver the ordered medication? (Document to the nearest whole number)
The Correct Answer is ["9"]
-
Dose in mcg/min=2 mcg/kg/min×60 kg=120 mcg/min
Convert this to mg/min since the concentration is in mg:
120 mcg/min=0.12 mg/min120 \text{ mcg/min} = 0.12 \text{ mg/min}120 mcg/min=0.12 mg/min
-
Determine the concentration of Dopamine:
- Total amount of Dopamine: 200 mg in 250 mL of saline
- Concentration:
Concentration=200 mg250 mL=0.8 mg/mL\text{Concentration} = \frac{200 \text{ mg}}{250 \text{ mL}} = 0.8 \text{ mg/mL}Concentration=250 mL200 mg=0.8 mg/mL
-
Calculate the pump rate in mL/min:
To find the rate in mL/min needed to deliver 0.12 mg/min:
Pump rate=Desired dose (mg/min)Concentration (mg/mL)\text{Pump rate} = \frac{\text{Desired dose (mg/min)}}{\text{Concentration (mg/mL)}}Pump rate=Concentration (mg/mL)Desired dose (mg/min)
Pump rate=0.12 mg/min0.8 mg/mL=0.15 mL/min\text{Pump rate} = \frac{0.12 \text{ mg/min}}{0.8 \text{ mg/mL}} = 0.15 \text{ mL/min}Pump rate=0.8 mg/mL0.12 mg/min=0.15 mL/min
-
Convert the pump rate to mL/hour:
Multiply by 60 to convert from mL/min to mL/hour:
Pump rate=0.15 mL/min×60 min/hour=9 mL/hour\text{Pump rate} = 0.15 \text{ mL/min} \times 60 \text{ min/hour} = 9 \text{ mL/hour}Pump rate=0.15 mL/min×60 min/hour=9 mL/hour
So, you should set the pump to deliver Dopamine at a rate of 9 mL/hour.

Correct Answer is D
Explanation
In septic shock, prompt administration of antibiotics is crucial in order to target the underlying infection and prevent further progression of the septic process. Antibiotics help to eradicate the causative organisms and reduce the bacterial load, which can help improve patient outcomes.
While all the options mentioned are important interventions in the management of septic shock, initiating antibiotic therapy is considered a priority in order to address the underlying infection and prevent sepsis-related complications.
A. Giving a 2000 mL normal saline bolus in (option A) is incorrect because: Fluid resuscitation is important in septic shock to restore intravascular volume, but antibiotic therapy takes precedence as it directly targets the underlying infection.
B. Starting an insulin drip to maintain blood glucose at 110 to 150 mg/dL in (option B) is incorrect because Glycemic control is important in septic shock, but it is not the first priority compared to addressing the infection.
C. Giving acetaminophen (Tylenol) 650 mg rectally in (option C) is incorrect because Antipyretic medications can help reduce fever, but they do not address the underlying infection or stabilize the patient's condition.
E. Starting norepinephrine (Levophed) to keep systolic blood pressure >90 mm Hg in (option E) is incorrect because: Vasopressor support may be necessary in septic shock to maintain adequate blood pressure, but initiating antibiotics takes priority in order to address the underlying infection.
Therefore, in a patient with septic shock presenting with the given signs and symptoms, the nurse should first implement the intervention of giving the prescribed antibiotics to target the underlying infection.
Correct Answer is B
Explanation
In this scenario, the patient's signs and symptoms suggest a state of shock, which can be caused by various factors, such as hypovolemia, cardiac dysfunction, or systemic vasodilation. The first priority in managing a patient in shock is to ensure adequate oxygenation and tissue perfusion. Administering oxygen at 100% per non-rebreather mask helps improve oxygen delivery to the tissues and supports vital organ function.
A. Placing the patient on a continuous cardiac monitor in (option A) is incorrect because it is an important step to monitor the patient's heart rhythm and identify any abnormalities. However, providing oxygen should take priority to address the potential hypoxemia and tissue hypoperfusion.
C. Inserting two 14-gauge IV catheters in (option C) is incorrect because it is crucial for establishing large-bore access for fluid resuscitation and medication administration. While it is an important step, addressing oxygenation takes precedence.
D. Drawing blood to type and crossmatch for transfusions in (option D) is incorrect because it is an important step in managing a patient in shock who may require blood products. However, ensuring adequate oxygenation through oxygen administration is the immediate priority.
Therefore, the nurse should act first on the order to administer oxygen at 100% per non-rebreather mask to support the patient's oxygenation and tissue perfusion.
