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 D

Explanation

A. 0.04 mg

  • This is far too small.

  • It might come from a miscalculation involving the concentration (1 mg/mL) and volume (5 mL), but incorrectly dividing again by 100.

  • Not clinically reasonable because the patient would barely receive any drug.

B. 0.25 mg

  • This is also incorrect.

  • It could result from mistakenly dividing 5 mg by 20 minutes instead of 2 minutes.

  • Again, far below the actual ordered rate.

C. 3.75 mg

  • This is incorrect but closer.

  • It might come from a misstep like subtracting 1.25 mg from the correct answer (2.5 mg) or misusing the concentration.

  • Still not the right calculation.

D. 2.5 mg

  • Correct answer.

  • Direct calculation: 5 mg ÷ 2 minutes = 2.5 mg/min.

  • Matches the ordered dose and administration time.

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.
