A nurse is preparing to administer 0.9% sodium chloride (NS) 100 mL/V to infuse over 4 hr. The drip factor of the manual IV tubing is 60 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number.)

27 gtt/min

25 gtt/min

23 gtt/min

30 gtt/min

Answer and Explanation

The Correct Answer is B

Given:

Volume of fluid: 100 mL

Infusion time: 4 hours

Drop factor: 60 gtt/mL

Formula:

Flow rate (gtt/min) = (Volume (mL) / Time (hr)) x Drop factor (gtt/mL) / 60 min/hr

Step 1: Calculate the infusion rate in mL/hr:

Infusion rate (mL/hr) = Volume (mL) / Time (hr)

Infusion rate (mL/hr) = 100 mL / 4 hr

Infusion rate (mL/hr) = 25 mL/hr

Step 2: Calculate the flow rate in gtt/min:

Flow rate (gtt/min) = (Infusion rate (mL/hr) x Drop factor (gtt/mL)) / 60 min/hr

Flow rate (gtt/min) = (25 mL/hr x 60 gtt/mL) / 60 min/hr

Flow rate (gtt/min) = 1500 gtt/hr / 60 min/hr

Flow rate (gtt/min) = 25 gtt/min

Correct Answer is B

Explanation

Given:

Ordered volume of Isomil: 12 oz

Step 1: Determine the volume of Isomil needed for 1/4 strength:

Volume of Isomil for 1/4 strength = Original volume x (1/4)

Volume of Isomil for 1/4 strength = 12 oz x (1/4)

Volume of Isomil for 1/4 strength = 3 oz

Step 2: Calculate the volume of solvent (water) needed:

Solvent volume = Original volume - Volume of Isomil for 1/4 strength

Solvent volume = 12 oz - 3 oz

Solvent volume = 9 oz

Step 3: Convert ounces to milliliters:

1 oz = 29.5735 mL

Solvent volume (mL) = 9 oz x 29.5735 mL/oz

Solvent volume (mL) = 266.1615 mL

Step 4: Round to the nearest whole number:

Solvent volume (mL) ≈ 270 mL

A. 5.524 kg B. 0.5524 kg C. 55.24 kg D. 5,524.00 kg

Correct Answer is A

Explanation

Given:

Value in grams: 5,524 g

To convert grams to kilograms, we need to divide the value by 1000.

Step 1: Divide the value by 1000:

5,524 g / 1000 = 5.524 kg
