The healthcare provider prescribes a liter of normal saline IV to be infused over 9 hours for a client who is NPO. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number).
Answer and Explanation

The Correct Answer is ["111"]

Here's how to calculate the rate for the infusion pump:

 

Total volume to infuse: 1 liter (given)

Infusion time: 9 hours (given)

We need to find the volume delivered per hour (mL/hour) considering the total volume and infusion time.

Volume conversion: Since the volume is given in liters, convert it to mL:

1 liter * 1000 mL/liter = 1000 mL

Infusion rate (mL/hour):

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

Infusion rate (mL/hour) = 1000 mL / 9 hours

Infusion rate (mL/hour) = 111.11 mL/hour (round to nearest tenth)

Therefore, the nurse should program the infusion pump to deliver approximately 111 mL/hour.

Explanation

Concentration of penicillin G benzathine: 1,200,000 units/2 mL (given on the syringe label)

Prescribed dose: 1,800,000 units

We need to find the volume (in mL) that delivers the prescribed dose (1,800,000 units) considering the available concentration.

Dosage calculation:

To administer the prescribed dose, we need to find the volume that contains at least 1,800,000 units.

Since the available concentration is 1,200,000 units/2 mL, one prefilled syringe provides 1,200,000 units.

We can calculate the number of syringes needed to deliver the prescribed dose:

Number of syringes = Prescribed dose (units) / Concentration per syringe (units)

Number of syringes = 1,800,000 units / 1,200,000 units/syringe

Number of syringes = 1.5 (round up to 2 since a partial dose wouldn't be sufficient)

2 mL per syringe x 2 syringes = 4 mL

However, the prefilled syringes likely come in whole-number doses. Checking the available options:

A single prefilled syringe provides 1,200,000 units (which is not enough).

Two prefilled syringes would provide a total of 2,400,000 units (more than enough).

Therefore, to ensure at least the prescribed dose is administered, the nurse should administer 3 mL.

This is achieved by using one and a half (rounded up to two) prefilled syringes.

Correct Answer is ["12000"]

Explanation

Here's how to calculate the total heparin units the client will receive in 12 hours

Heparin concentration:

The medication is delivered in a 500 mL bag containing 20,000 units of heparin.

Heparin concentration (units/mL) = Total heparin (units) / Volume (mL)

Heparin concentration (units/mL) = 20,000 units / 500 mL

Heparin concentration (units/mL) = 40 units/mL

Infusion rate: 25 mL/hour (given)

Time: 12 hours (given)

We need to find the total number of heparin units delivered in 12 hours.

Total volume delivered in 12 hours:

Volume delivered (mL/hour) x Time (hours) = Total volume delivered (mL)

25 mL/hour x 12 hours = 300 mL

Total heparin units delivered:

Heparin concentration (units/mL) x Total volume delivered (mL) = Total heparin units

40 units/mL x 300 mL = 12,000 units

Therefore, the client will receive 12,000 units of heparin in 12 hours.
