Find the total time to infuse __________.

Ordered: 1,000 mL NS@ 6 50 mL/h using an infusion pump
Answer and Explanation

The Correct Answer is ["1.54"]

Given values:

Total volume = 1,000 mL

Infusion rate = 650 mL/h

  • Calculate the total time in hours using the formula:

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

          = 1,000 mL / 650 mL/h

          = 1.53846 h

  • Rounded to two decimal places

= 1.54 h.

Correct Answer is ["167"]

Explanation

Given values:

Total volume = 1,000 mL

Infusion time = 6 h

  • Calculate the flow rate in mL/h using the formula:

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

= 1000 mL / 6 h

= 166.6667 mL/h.

  • Round the answer to the nearest whole number.

= 167 mL/h.

Correct Answer is C

Explanation

A. tuberculin syringe: Tuberculin syringes are calibrated in milliliters (typically 1 mL total) and not in insulin units. Using them for insulin risks serious dosing errors due to miscalculation or misreading.

B. U-100, 50 unit capacity insulin syringe: This syringe only holds up to 50 units of insulin. Since the ordered dose is 60 units, this syringe is not large enough and should not be used for this administration.

C. U-100, 100 unit capacity insulin syringe: This is the correct syringe for giving 60 units of insulin. It is specifically calibrated for insulin dosing and can measure up to 100 units accurately and safely.

D. standard syringe: Standard syringes are usually marked in milliliters, not insulin units. Using them for insulin administration increases the risk of dosing errors and is not recommended for safety reasons.
