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 []

Explanation

Hypocalcemia:

- Condition: Hypocalcemia is a condition characterized by low levels of calcium in the blood. In newborns and infants, this can occur due to inadequate intake or absorption of calcium, and it can manifest as seizures.

- Rationale: The infant was fed cow's milk, which is not recommended for infants under one year old and can interfere with calcium absorption, possibly leading to hypocalcemia. Seizures can be a symptom of severe hypocalcemia.

Actions to Take:

1. Administer oral calcium:

- Rationale: Direct administration of calcium helps to quickly elevate calcium levels in the blood, addressing the immediate cause of the seizures.
2. Educate the mother on nutrition needs:

- Rationale: It's important to educate the mother on the appropriate nutritional needs for an

infant, emphasizing the importance of breastfeeding or formula feeding instead of cow's milk, to prevent recurrence.

Parameters to Monitor:

1. Electrocardiogram:

- Rationale: Monitoring the ECG is crucial as hypocalcemia can cause cardiac arrhythmias, and the ECG can provide real-time information about the infant's cardiac status.
2. Oxygen saturation:

- Rationale: Monitoring oxygen saturation ensures that the infant maintains adequate oxygenation, especially after a seizure and during recovery, to detect any respiratory complications early.

Correct Answer is ["100.0"]

Explanation

Total volume of the infusion: 50 mL (saline bag)
Infusion time: 30 minutes = 0.5 hours (convert minutes to hours)
We don't need the concentration of gentamicin for this calculation because we're only interested in the total volume delivered per hour.
Flow rate: Since all the medication is delivered within the infusion time, the flow rate is equal to the total volume divided by the infusion time.

Flow rate (mL/hour) = Total volume (mL) / Infusion time (hours)

Flow rate = 50 mL / 0.5 hours Flow rate = 100.0 mL/hour

Therefore, the nurse should set the pump to deliver 100.0 mL/hour to infuse the 60 mg of gentamicin over 30 minutes.
