A client is currently receiving an infusion labeled Heparin Sodium 25,000 Units in 5% Dextrose Injection 500 mL at 14 ml/hour. A prescription is received to change the rate of the Infusion to 900 units of heparin per hour. The nurse should set the infusion pump to deliver how many mL/hour? (Enter numeric value only.)
The Correct Answer is ["18"]
First, we need to find the concentration of Heparin per milliliter in the current infusion. We can do this by dividing the total number of Heparin units by the total volume of the infusion:
Heparin concentration (units/mL) = Total Heparin units / Total volume (mL) Heparin concentration = 25,000 units / 500 mL
Heparin concentration = 50 units/mL
Now, we know the desired rate of Heparin delivery (900 units/hour) and the concentration of Heparin per milliliter (50 units/mL). We can use this information to calculate the required flow rate in milliliters per hour:
Flow rate (mL/hour) = Desired Heparin rate (units/hour) / Heparin concentration (units/mL)
Flow rate = 900 units/hour / 50 units/mL Flow rate = 18 mL/hour
Therefore, the nurse should set the infusion pump to deliver 18 mL/hour.

Correct Answer is ["6.8"]
Explanation
Converting the weight to kg:
Client weight = 198 lbs 1 lb = 0.453592 kg
Client weight in kg = 198 lbs 0.453592 kg/lb = 90.7 kg
Calculating the desired dopamine infusion rate:
Dose = 2 mcg/kg/minute Client weight = 90.7 kg
Desired infusion rate = Dose Client weight = 2 mcg/kg/minute 90.7 kg = 181.4 mcg/minute
Determining the dopamine concentration in the bag:
Dopamine amount = 400 mg Bag volume = 250 mL
Dopamine concentration = Dopamine amount / Bag volume = 400 mg / 250 mL = 1.6 mg/mL
Convert mg/mL to mcg/mL: 1.6 mg/mL 1000 mcg/mg = 1600 mcg/mL
Calculating the rate in mL/minute:
Desired infusion rate = 181.4 mcg/minute Dopamine concentration = 1600 mcg/mL
Rate (mL/minute) = Desired infusion rate (mcg/minute) / Dopamine concentration (mcg/mL)
Rate = 181.4 mcg/minute / 1600 mcg/mL = 0.1134 mL/minute
Converting the rate to mL/hour:
Rate (mL/minute) = 0.1134 mL/minute Conversion factor: 60 minutes/hour
Rate (mL/hour) = 0.1134 mL/minute 60 minutes/hour = 6.8 mL/hour (round to nearest tenth)
Therefore, the nurse should set the IV pump to deliver approximately 6.8 mL/hour.
Correct Answer is {"dropdown-group-1":"B","dropdown-group-2":"C"}
Explanation
Semi Fowler's position:
- This position involves raising the head of the bed to an angle of 30 to 45 degrees. It is
commonly used to improve respiratory function and comfort in patients who are experiencing
difficulty breathing. By elevating the head and torso, this position facilitates better lung expansion, helping to improve oxygenation.
Promote lung expansion:
- In patients with respiratory issues such as pneumonia, positioning that enhances lung expansion is critical. Semi Fowler's position helps to reduce pressure on the diaphragm, allowing for more effective lung expansion and improved oxygenation. This is particularly important for a patient with decreased breath sounds and consolidation in the lungs, as it aids in alleviating respiratory distress and improving gas exchange.
