A client is receiving an intravenous infusion of 1.5 L of saline solution at a rate of 75 mL/hr.
How many hours will it take to finish the infusion at the current rate?
10 hours
7.5 hours
20 hours
15 hours
The Correct Answer is C
To find the hours to finish the infusion, you need to calculate the following:
- The volume of saline solution in milliliters
- The time in hours using the formula: Time (h) = Total volume (mL) / Infusion rate (mL/h)
First, convert the volume of saline solution from liters to milliliters by multiplying by 1000:
1.5 L x 1000 = 1500 mL
Next, use the formula for time to find how many hours it will take to infuse the saline solution at the current rate:
Time (h) = Total volume (mL) / Infusion rate (mL/h)
Since the total volume is 1500 mL and the infusion rate is 75 mL/h, plug in these values into the formula:
Time (h) = 1500 mL / 75 mL/h
Simplify and solve for the time:
Time (h) = 20 h
Therefore, it will take **20 hours** to finish the infusion at the current rate.

Correct Answer is C
Explanation
The instruction that should be given to this client for the effective management of hypertension is to take
**five tablets** of bisoprolol per day, each containing 100 mg.
This is because the new order of 500 mg of bisoprolol per day is twice as much as the current dose of 250 mg of bisoprolol per day (two and a half tablets of 100 mg each). Therefore, the client needs to double the number of tablets they take per day from two and a half to five.
Correct Answer is B
Explanation
This is another dosage calculation problem. To solve it, we need to use the formula:
Caloric need ÷ Calories per mL 1000 = Formula per day
In this case, the caloric need is 2250 calories, and the calories per mL is 2000/1000 = 2. Plugging these values into the formula, we get:
2250 ÷ 2 × 1000 = 1125
Therefore, the client would need **1125 mL** of formula per day to meet the calorie requirements.
