An adolescent patient is to receive 50 mL of Cefazolin IV over 40 minutes. With a tubing drop factor of 20 gtt/mL, how many drops per minute (gtt/min) should be given?

Answer and Explanation

The Correct Answer is ["25"]

To calculate the drops per minute for an IV infusion, we need to use the following formula:

gtt/min = (volume x drop factor) / time

In this case, the volume is 50 mL, the drop factor is 20 gtt/mL, and the time is 40 minutes. Plugging these values into the formula, we get:

gtt/min = (50 x 20) / 40

gtt/min = 1000 / 40

gtt/min = 25

Therefore, the adolescent patient should receive 25 drops per minute of Cefazolin IV.

Explanation

A. “We will keep our household hot water heater at 130 degrees.”

The recommended setting for a hot water heater is typically 120 degrees Fahrenheit to prevent scalds. Setting it at 130 degrees may still pose a risk of burns to young children.

B. “We will place poisonous substances in a high cupboard.”

Placing poisonous substances out of reach in a high cupboard is a safety measure to prevent children from accessing potentially harmful substances.

C. “We will place a gate at the top and bottom of stairways.”

Using safety gates at the top and bottom of stairways is an effective way to prevent young children from falling down stairs.

D. “We will put plastic fillers in all electrical plugs.”

Placing plastic fillers in electrical plugs helps prevent children from inserting objects into outlets, reducing the risk of electric shock.

E. “We will turn handles of pans on the stove toward the back of the stove.”

Turning handles of pans on the stove toward the back is a safety measure to prevent young children from reaching up and pulling hot items off the stove.

Correct Answer is ["0.1696"]

Explanation

To calculate the ordered dose by the physician in mg/kg/dose, we need to convert the infant's weight from pounds and ounces to kilograms. One pound is equal to 0.4536 kg and one ounce is equal to 0.02835 kg. Therefore, the infant's weight in kilograms is:

6 x 0.4536 + 3 x 0.02835 = 2.948 kg

The ordered dose by the physician is 0.5 mg IV q 2 hours prn. To find the dose in mg/kg/dose, we divide the dose in mg by the weight in kg:

0.5 / 2.948 = 0.1696 mg/kg/dose

The recommended dosage for a child is 0.1-0.2 mg/kg/dose q2-4 hours prn. The ordered dose by the physician falls within this range, so it is a safe dosage for the infant.
