A practical nurse is assigned to care for an adult client who is receiving intravenous fluid therapy for fluid volume deficit following an episode of gastroenteritis. The client has a heart rate of $108$ bpm and a blood pressure of $98/60$ mmHg. The healthcare provider has prescribed $500$ mL of $0.9\%$ sodium chloride to infuse over $6$ hours. The primary intravenous tubing has a drop factor of $20$ gtt/mL. At how many drops per minute (gtt/min) should the infusion be regulated? Record the answer to the nearest whole number. Do not include units in the answer.

Cevap: 28 gtt/min

Cevap

The correct drip rate is calculated by multiplying the total volume to be infused (

500

mL) by the administration set's drop factor (

20

gtt/mL) to determine the total number of drops. This total (

10,000

drops) is then divided by the total time in minutes (

360

minutes). The resulting quotient of

27.777...

is rounded to the nearest whole number, yielding a final regulatory rate of

28

drops per minute.

Adım Adım Çözüm

Convert the total infusion time from hours to minutes.

6 \text{ hours} \times 60 \text{ minutes/hour} = 360 \text{ minutes}

The standard intravenous drip rate formula requires the time variable to be expressed in minutes.

Apply the standard intravenous drip rate formula.

\frac{500 \text{ mL} \times 20 \text{ gtt/mL}}{360 \text{ minutes}} = 27.777... \text{ gtt/min}

This formula determines the number of drops infused per minute based on the prescribed volume, the tubing's specific drop factor, and the total duration.

Round the calculated rate to the nearest whole drop.

28 \text{ gtt/min}

Fractions of a drop cannot be visually measured or administered via a manual gravity infusion set.
