Twenty-four correctly written as a Roman numeral is

A.

XXIIII.

B.

XXIV.

C.

Xxiiii

D.

xixv

Answer and Explanation

The Correct Answer is B

A. XXIIII: While this form was used in ancient times, it is now considered incorrect by modern Roman numeral standards. Roman numerals should follow subtractive notation, where 4 is written as IV, not IIII.

B. XXIV: This is the correct modern Roman numeral for 24. It combines 20 (XX) and 4 (IV) using the proper subtractive rule for the numeral 4.

C. Xxiiii: Roman numerals must be written in uppercase to be considered correct. This option also uses an outdated form (IIII for 4) and mixes cases.

D. xixv: This is not a valid Roman numeral. It incorrectly places symbols and uses lowercase letters, violating both formatting and value rules.

Correct Answer is C

Explanation

A. the remaining volume and original time: Using the original time does not reflect how much time is actually left for the infusion. This could lead to under- or over-infusion if the clock has already started.

B. the original volume and time: This method is used only at the start of the infusion. Once some fluid has already infused, this combination is no longer valid for adjusting the current flow rate.

C. the remaining volume and time: To accurately adjust the flow rate mid-infusion, the nurse must use the amount of fluid left to infuse and the remaining time ordered for the infusion. This ensures the patient receives the correct volume within the prescribed timeframe.

D. the original volume and remaining time: Using the full original volume over the shortened remaining time would lead to an excessively high flow rate, potentially causing fluid overload or complications.

Correct Answer is ["13"]

Explanation

Total volume = 1,800 mL

Infusion time = 24 hours

Drop factor = 10 gtt/mL

  • Convert the infusion time from hours to minutes.

Infusion time in minutes = 24 hours × 60 minutes/hour

= 1440 minutes.

  • Calculate the flow rate in drops per minute (gtt/min) using the formula:

Flow rate (gtt/min) = (Total volume (mL) × Drop factor (gtt/mL)) / Infusion time (min)

= (1800 mL × 10 gtt/mL) / 1440 min

= 18000 / 1440

= 12.5 gtt/min.

  • Round the answer to the nearest whole number.

= 13 gtt/min.
