A nurse is preparing to administer lactated Ringer's 500 mL IV to infuse over 4 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["125"]

To calculate the infusion rate for lactated Ringer's solution, the nurse should divide the total volume of fluid by the total time of infusion.

In this case, the nurse should divide 500 mL by 4 hr, which equals 125 mL/hr.

Therefore, the nurse should set the IV pump to deliver 125 mL/hr of lactated Ringer's solution.

Correct Answer is ["0.7"]

Explanation

To calculate the dose of chlorpromazine for a child who weighs 66 lb, first convert the weight to kilograms by dividing by 2.2.

This gives 66 / 2.2 = 30 kg.

Then multiply the weight by the prescribed dose of 0.55 mg/kg to get the total dose in milligrams: 30 x 0.55 = 16.5 mg.

Finally, divide the total dose by the concentration of the injection solution to get the volume in milliliters: 16.5 / 25 = 0.66 ml.

The nurse should administer 0.7 ml of chlorpromazine IM to the child.

Correct Answer is ["10"]

Explanation

To calculate the dose of amoxicillin oral suspension for a client, the nurse needs to use the following formula: Dose (mL) = Desired dose (mg) / Available dose (mg/mL) x Volume (mL).

In this case, the desired dose is 500 mg, the available dose is 250 mg/5 mL, and the volume is 5 mL.

Therefore, the dose (mL) = 500 mg / (250 mg/5 mL) x 5 mL = 10 mL.

The nurse should administer 10 mL of amoxicillin oral suspension to the client.
