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.)
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 ["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)
Correct Answer is ["8"]
Explanation
You can calculate the number of acyclovir tablets the nurse should administer every 24 hours using the following steps:
Daily Dosage: The medication is prescribed to be given every 6 hours, so to find the total daily dosage, we need to consider how many times it's administered in 24 hours:
Total Daily Doses = 24 hours / Dosage Frequency (every 6 hours)
Total Daily Doses = 24 hours / 6 hours/dose = 4 doses per day
Tablets per Dose: Since the prescribed dose is 800 mg and each tablet is 400 mg, we can find the number of tablets needed per dose:
Tablets per Dose = Prescribed Dose (mg) / Tablet Strength (mg/tablet)
Tablets per Dose = 800 mg / 400 mg/tablet = 2 tablets/dose
Total Tablets per Day: Now that we know the tablets needed per dose (2) and the total daily doses (4), we can find the total number of tablets for 24 hours:
Total Tablets per Day = Tablets per Dose x Total Daily Doses
Total Tablets per Day = 2 tablets/dose * 4 doses/day
Total Tablets per Day = 8 tablets
Therefore, the nurse should administer 8 tablets of acyclovir to the client every 24 hours.
