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.)

Answer and Explanation

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 ["0.8"]

Explanation

Convert the client's weight from pounds to kilograms (kg).
Calculate the enoxaparin sodium dosage per day based on the client's weight and the prescribed dosage of 1.5 mg/kg/day.
Divide the enoxaparin sodium dosage by the concentration of the medication in the prefilled syringe (120 mg/0.8 mL) to determine the volume to administer.

Step 1: Convert weight from pounds to kilograms

- Client's weight in kg = Client's weight in pounds / 2.2
- Client's weight in kg = 176 pounds / 2.2 = 80 kg

Step 2: Calculate enoxaparin sodium dosage per day

- Enoxaparin sodium dosage (mg/day) = Client's weight (kg) × Prescribed dosage (mg/kg/day)
- Enoxaparin sodium dosage (mg/day) = 80 kg × 1.5 mg/kg/day = 120 mg/day

Step 3: Determine the volume to administer

- Volume to administer (mL) = Enoxaparin sodium dosage (mg/day) / Medication concentration (mg/mL)
- Volume to administer (mL) = 120 mg/day / (120 mg/0.8 mL) = 0.8 mL

Therefore, the nurse should administer 0.8 mL of enoxaparin sodium to the client.

A. Promote healing process. B. Decrease abdominal pain. C. Reduce intestinal activity. D. Control diarrhea episodes. E. None F. None

Correct Answer is C

Explanation

Activity restriction does not directly decrease abdominal pain. Pain management in Crohn’s disease is typically achieved through medications, dietary adjustments, and addressing inflammation.

B. While activity restriction may indirectly help decrease abdominal pain by reducing inflammation and promoting healing, it is not the primary purpose of the restriction.
C.The primary goal of activity restriction in Crohn's disease is to reduce intestinal activity. By limiting physical exertion, the intestines are less stimulated, which can help reduce inflammation and give the digestive system a chance to rest and recover.
D. While activity restriction may help control diarrhea episodes by reducing physical stress on the intestines, the primary purpose is to promote healing and reduce inflammation. Control of diarrhea may be achieved through other interventions such as dietary modifications and
medication management.
