The health-care provider prescribes penicillin 700,000 Units IM daily. The available vial is labeled, Penicillin 500,000 Units/ml. How many milliliters should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.4"]
To calculate the volume of penicillin to be administered, we can use the following formula:
Volume (mL) = Desired Dose (Units) / Concentration (Units/mL)
Plugging in the given values:
Volume (mL) = 700,000 Units / 500,000 Units/mL
Calculating the result:
Volume (mL) = 1.4 mL
Therefore, the nurse should administer 1.4 mL of penicillin.

Correct Answer is B
Explanation
Step 1: Calculate the infant's weight in kilograms:
22 pounds x (1 kg / 2.20462 pounds) ≈ 10 kg
Step 2: Calculate the recommended maximum daily dose:
Recommended Maximum Dose = 3.5 mg/kg/day x 10 kg
Recommended Maximum Dose = 35 mg/day
Step 3: Calculate the prescribed daily dose:
Prescribed Daily Dose = 0.87 mg/dose x 4 doses/day
Prescribed Daily Dose = 3.48 mg/day
Step 4: Compare the prescribed dose to the recommended maximum dose:
The prescribed daily dose (3.48 mg/day) is slightly above the recommended maximum daily dose (35 mg/day).
Therefore, the nurse should:
B. Assess the child's heart rate before administration.
While the prescribed dose is slightly above the recommended maximum, it's important to monitor the child's heart rate to ensure there are no adverse effects. If the heart rate is within the normal range, the medication can be administered. However, if there are any concerns, the nurse should consult with the health-care provider.
Correct Answer is ["160"]
Explanation
Calculate the average hourly NGT output:
Average Hourly NGT Output = Total NGT Output / Number of Hours
Average Hourly NGT Output = 240 mL / 4 hours
Average Hourly NGT Output = 60 mL/hour
Adjust the IV rate:
New IV Rate = Current IV Rate + Average Hourly NGT Output
New IV Rate = 100 mL/hour + 60 mL/hour
New IV Rate = 160 mL/hour
Therefore, the nurse should regulate the IV to deliver 160 mL/hour to replace the fluid loss.
