Find the total time to infuse:

Ordered 250 ml. D5LR @ 10 mL/h using an infusion pump
Answer and Explanation

The Correct Answer is ["25"]

Given values:

Total volume = 250 mL

Infusion rate = 10 mL/h

  • Calculate the total time in hours using the formula:

Total time (h) = Total volume (mL) / Infusion rate (mL/h)

          = 250 mL / 10 mL/h

          = 25 h.

Correct Answer is A

Explanation

A. 4,500 mg: (1/2) NS refers to a half-strength normal saline solution. Normal saline (0.9% NaCl) contains 9 grams, which is 9,000 mg, of sodium chloride per 1,000 mL. Therefore, a half-strength solution will contain exactly half of this amount, which is 4,500 mg.

B. 9,000 mg: A concentration of 9,000 mg of sodium chloride would be found in 1,000 mL of a full-strength normal saline solution (NS or 0.9% NaCl), not a half-strength solution. This represents the total amount of NaCl in a standard liter of NS.

C. 2,250 mg: This value is a quarter of the total sodium chloride found in a liter of normal saline. This amount would be found in a quarter-strength normal saline solution (1/4 NS), which is a different concentration than what is specified.

D. 500 mg: While 500 mg of dextrose is present per 100 mL of D5W, this value does not represent the sodium chloride content of any standard IV solution.

Correct Answer is B

Explanation

Calculation:

Total tablets = 28 tablets.

  • Calculate the number of tablets to be taken per day.

The order is to take 1 tablet every 6 hours ("q6h").

Number of doses per day = 24 hours / 6 hours/dose

= 4 doses per day.

Since each dose is 1 tablet, the patient takes 4 tablets per day.

  • Calculate the total days' supply.

Days' supply = Total tablets / Tablets per day

= 28 tablets / 4 tablets/day

= 7 days.
