The physician orders Kefzol 2 g in 50 mL of NS IVPB to infuse over 30 minutes. Tubing drop factor is 60 gtt/mL. Calculate the flow rate in drops per minute.

Answer and Explanation

The Correct Answer is ["100"]

Calculation:

Total volume to be infused = 50 mL.

Infusion time in minutes = 30 minutes.

Tubing drop factor = 60 gtt/mL.1

Calculate the flow rate in drops per minute (gtt/min).

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

= (50 mL × 60 gtt/mL) / 30 min

= 3000 / 30 gtt/min

= 100 gtt/min.

Correct Answer is ["42"]

Explanation

Calculation:

Convert the infusion rate from milliliters per hour (mL/hr) to milliliters per minute (mL/min).

Infusion rate in mL/min = 125 mL/hr / 60 min/hr

= 2.0833... mL/min.

Tubing drop factor = 20 gtt/mL.

Calculate the flow rate in drops per minute (gtt/min).

Flow rate (gtt/min) = Infusion rate (mL/min) × Tubing drop factor (gtt/mL)

= 2.0833... mL/min × 20 gtt/mL

= 41.666... gtt/min.

Round the answer to the nearest whole number.

= 42 gtt/min.

A. respirations that cease for several seconds B. Respirations that are regular but abnormally slow C. Respirations that are labored. and decreased in depth and rate D. Respirations that are abnormally deep, regular, and increased in rate

Correct Answer is D

Explanation

A. Respirations that cease for several seconds: This describes periodic breathing or Cheyne-Stokes respirations, which are not characteristic of Kussmaul’s respirations. Kussmaul’s respirations are marked by rapid and deep breathing, not cessation of breathing.

B. Respirations that are regular but abnormally slow: This describes bradypnea, which is not associated with diabetic ketoacidosis (DKA). Kussmaul’s respirations are fast and deep, not slow.

C. Respirations that are labored, and decreased in depth and rate: Labored, shallow breathing is not characteristic of Kussmaul’s respirations. Instead, Kussmaul’s respirations are deep and rapid, a compensatory mechanism for metabolic acidosis in DKA.

D. Respirations that are abnormally deep, regular, and increased in rate: Kussmaul’s respirations are deep, rapid, and regular, which are a physiological response to help decrease CO2 levels and correct the acidosis seen in DKA.
