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.

Answer and Explanation

The Correct Answer is ["21"]

flow rate for an infusion= (Volume in mL * Drop factor) / Time in minutes.

volume of the infusion bag is 250 mL, the drop factor is 10 gtts/mL, and the time is 2 hours, which is 120 minutes.

(250 mL * 10 gtts/mL) / 120 minutes = 2500 gtts / 120 minutes ≈ 20.83 gtts/minute. Therefore, the nurse should run the infusion at a rate of approximately 21 drops per minute to deliver 1 unit of packed red blood cells over the 2-hour period.

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.

Correct Answer is ["9"]

Explanation

Doseinmcg/min=2mcg/kg/min×60kg=120mcg/min

Convert this to mg/min since the concentration is in mg:

120mcg/min=0.12mg/min120 \text{ mcg/min} = 0.12 \text{ mg/min}120mcg/min=0.12mg/min
Determine the concentration of Dopamine:
- Total amount of Dopamine: 200 mg in 250 mL of saline
- Concentration:
Concentration=200mg250mL=0.8mg/mL\text{Concentration} = \frac{200 \text{ mg}}{250 \text{ mL}} = 0.8 \text{ mg/mL}Concentration=250mL200mg=0.8mg/mL
Calculate the pump rate in mL/min:

To find the rate in mL/min needed to deliver 0.12 mg/min:

Pumprate=Desireddose(mg/min)Concentration(mg/mL)\text{Pump rate} = \frac{\text{Desired dose (mg/min)}}{\text{Concentration (mg/mL)}}Pumprate=Concentration(mg/mL)Desireddose(mg/min)

Pumprate=0.12mg/min0.8mg/mL=0.15mL/min\text{Pump rate} = \frac{0.12 \text{ mg/min}}{0.8 \text{ mg/mL}} = 0.15 \text{ mL/min}Pumprate=0.8mg/mL0.12mg/min=0.15mL/min
Convert the pump rate to mL/hour:

Multiply by 60 to convert from mL/min to mL/hour:

Pumprate=0.15mL/min×60min/hour=9mL/hour\text{Pump rate} = 0.15 \text{ mL/min} \times 60 \text{ min/hour} = 9 \text{ mL/hour}Pumprate=0.15mL/min×60min/hour=9mL/hour

So, you should set the pump to deliver Dopamine at a rate of 9 mL/hour.

Correct Answer is ["9"]

Explanation

The medical-surgical nurse is caring for a 55-year-old female patient after surgery. The patient's respiratory rate has increased from 12 to 22 breaths/min, and the pulse rate has increased from 86 to 110 beats/min since the patient was last assessed 4 hours ago. What action by the nurse is best?

The surgical ICU nurse is caring for postoperative clients at risk for hypovolemic shock. Which condition represents an early symptom of shock?

The cardiac ICU nurse is assessing a patient who is in cardiogenic shock. Which hemodynamic manifestations and/or signs and symptoms do the nurse expect? Select all that apply.

Which of the following is the most accurate assessment of tissue perfusion in a patient in shock?

A 66-year-old female patient in septic shock has received fluid resuscitation, but their mean arterial pressure (MAP) is 52 mmHg. The nurse anticipates the administration of which one of the following?

When assessing the hemodynamic information for a newly admitted patient in shock of unknown etiology, the emergency department nurse will anticipate the administration of large volumes of Lactated Ringers (LR) when which one of the following occurs?
