A client is receiving intravenous infusion of 1.5 L saline solution at a rate of 75 mL/hr.
How many hours will it take to finish the infusion at the current rate?

A.

20 hours

B.

10 hours

C.

15 hours

D.

75 hours

Answer and Explanation

The Correct Answer is A

To calculate the time it will take to finish the infusion, we can use the formula:

Time = Volume / Rate

Plugging in the given values, we get:

Time = 1.5 L / 75 mL/hr Converting 1.5 L to mL, we get:

Time = 1500 mL / 75 mL/hr Simplifying, we get:

Time = 20 hours

Therefore, it will take 20 hours to finish the infusion at the current rate.

Correct Answer is C

Explanation

A. 5ML: One tablespoon is equivalent to 15 milliliters, so 5 milliliters is too little for the prescribed dose.
B. 10ML: This amount is also insufficient, as it does not match the standard conversion of one tablespoon to milliliters.
C. 15ML: This is the correct conversion, as one tablespoon is equal to 15 milliliters.
D. 30ML: This amount is double the correct dose, which could lead to overmedication and potential side effects.

Correct Answer is B

Explanation

To calculate the dose of dobutamine in mg/hr, we need to convert the patient's weight from pounds (lb) to kilograms (kg) and then use the ordered dose of 10 mcg/kg/min.

1 lb = 0.453592 kg (rounded to 6 decimal places) Patient's weight in kg = 110 lb x 0.453592 kg/lb

Patient's weight in kg = 49.89512 kg (rounded to 5 decimal places)

Now we can calculate the dose of dobutamine in mg/hr using the following formula:

Dose (in mg/hr) = Weight (in kg) x Dose (in mcg/kg/min) x 60 (to convert minutes to hours) / 1000 (to convert mcg to mg)

Dose (in mg/hr) = 49.89512 kg x 10 mcg/kg/min x 60 / 1000

Dose (in mg/hr) = 29.937072 mg/hr (rounded to 3 decimal places)

Therefore, the patient should receive a dose of approximately 29.9 mg/hr of dobutamine.
