A client is receiving heparin IV at a rate of 1,800 units/hour. The IV solution is labeled, "Heparin sodium 20,000 units in 5% dextrose Injection 500 mL." After receiving the partial thromboplastin time (PTT) result, the healthcare provider prescribes an increase of 5 ml/hour in the IV rate. The nurse should set the infusion pump to deliver how many ml/hour? (Enter numeric value only.)

Answer and Explanation

The Correct Answer is ["50"]

First, we need to find out how many mL/hr the infusion pump is currently delivering.

Given:

The client is receiving 1,800 units/hour of heparin.

The available medication is 20,000 units/500 mL.

We can set up the proportion as follows:

1,800 units/ x mL = 20,000 units/500 mL

Solving for x gives us the volume in mL that the infusion pump is currently delivering per hour.

Cross-multiplying and solving for x:

X = 1,800 units×500 mL/20,000 units

After performing the calculation, we find that x equals 45 mL/hr.

Given that the healthcare provider prescribes an increase of 5 mL/hr in the IV rate, the nurse should set the infusion pump to deliver:

New rate (mL/hr) = Current rate (mL/hr) + Increase (mL/hr) = 45 mL/hr+5 mL/hr

After performing the calculation, we find that the new rate equals 50 mL/hr.

So, the nurse should set the infusion pump to deliver 50 mL/hr.

Correct Answer is ["0.7"]

Explanation

The nurse should administer 0.7 mL of diphenhydramine.

Here's the calculation:

Medication dosage: 35 mg (diphenhydramine)

Medication concentration: 50 mg/mL (given on the syringe label)

We need to find the volume (mL) containing the prescribed dose (35 mg) of diphenhydramine.

Volume to administer (mL) = Dose (mg) / Concentration (mg/mL)

Volume to administer (mL) = 35 mg / 50 mg/mL

Volume to administer (mL) = 0.7 mL (round to nearest tenth)

Therefore, the nurse should administer 0.7 mL of diphenhydramine

Correct Answer is ["59.147"]

Explanation

Here's how to calculate the number of mL the nurse should document:

Client dosage: 2 ounces (given)

Conversion factor: 1 ounce (oz) = 29.5735 mL (conversion factor)

Magnesium hydroxide concentration: 400 mg per 5 mL (from bottle label)

We need to find the equivalent volume in mL of the 2 ounces dosage the client reported.

Steps:

a. Convert ounces to mL:

Client dosage (mL) = Client dosage (oz) x Conversion factor (mL/oz)

Client dosage (mL) = 2 oz * 29.5735 mL/oz

Client dosage (mL) = 59.147 mL (round to nearest hundredth)
