A 57-year-old male patient in DIC is to receive 1 unit of packed red blood cells over 2 hours. There is 250 mL in the infusion bag. The IV administration infusion set delivers 10 gtts/mL. At what flow rate (in drops per minute) should the nurse run the infusion?

Record your answer using a whole number.

Cool, clammy skin, tachycardia, and hypotension are signs of shock, indicating inadequate tissue perfusion and oxygenation. The immediate priority is to ensure adequate oxygen delivery to the tissues. Providing oxygen at 100% via a non-rebreather mask helps increase the patient's oxygen saturation and improve tissue oxygenation.
While all the options mentioned are important in the management of a patient in shock, oxygenation takes priority as it directly addresses compromised tissue perfusion and oxygenation.
A. Inserting two large-bore IV catheters in (option A) is incorrect because: Establishing intravenous access is crucial for fluid resuscitation and administration of medications, but it can be done after ensuring adequate oxygenation.
C. Drawing blood to type and crossmatch for transfusions in (option C) is incorrect because Blood typing and crossmatching are important for potential blood transfusions but should not be the first action in this critical situation.
D. Initiating continuous electrocardiogram (ECG) monitoring in (option D) is incorrect because Continuous ECG monitoring is important for assessing cardiac rhythm and detecting any dysrhythmias, but ensuring oxygenation should be the initial priority.
Therefore, in a patient presenting with cool, clammy skin, tachycardia, and hypotension, the nurse should first provide oxygen at 100% via a non-rebreather mask to address inadequate tissue perfusion and oxygenation.

Step 1: Convert the patient's weight from pounds to kilograms. 130 pounds ÷ 2.205 (1 pound = 0.453592 kilograms) ≈ 58.97 kilograms

Step 2: Calculate the total dosage of Dobutamine required per hour based on the weight-specific dose. 2.5 mcg/kg/min × 58.97 kg = 147.425 mcg/min

Step 3: Calculate the infusion rate (mL/hr) using the concentration of Dobutamine in the prepared solution. The solution contains 250 mg of Dobutamine in 500 mL, which means there are 250,000 mcg of Dobutamine in 500 mL. To determine the mL/hr, divide the required dosage (147.425 mcg/min) by the amount of Dobutamine in 500 mL (250,000 mcg) and multiply by 500 mL (volume of the solution).

(147.425 mcg/min ÷ 250,000 mcg) × 500 mL ≈ 0.295 mL/min

To get the mL/hr, we convert the rate from minutes to hours (60 minutes = 1 hour):

0.295 mL/min × 60 min/hr ≈ 17.7 mL/hr

Round the answer to the nearest whole number:

Approximately 18 mL/hr of Dobutamine should be administered to the patient.
