A nurse is preparing to administer cefazolin 40 mg/kg/day IV bolus divided in equal doses every 12 hr to a neonate who weighs 5 kg Available is cefazolin injection 330 mg/mL. How many mL should the nurse administer per dose?
The Correct Answer is ["0.3"]
To calculate the dose of cefazolin for a neonate, first multiply the weight by the dosage per day: 5 kg x 40 mg/kg/day = 200 mg/day. Then divide by the number of doses per day: 200 mg/day / 2 doses/day = 100 mg/dose. Next, use the formula D/H x Q to find the volume to administer, where D is the dose, H is the strength of the solution, and Q is the quantity of the solution. Plug in the values: 100 mg / 330 mg/mL x 1 mL = 0.3 mL. Round to the nearest tenth: 0.3 mL. Therefore, the nurse should administer 0.3 mL of cefazolin per dose.

Correct Answer is ["14"]
Explanation
To answer this question, the nurse needs to perform the following steps:
Convert the client's weight from pounds to kilograms by dividing it by 2.2. 154 lb / 2.2 = 70 kg.
Multiply the client's weight by the loading dose of phenytoin to get the total dose in milligrams. 70 kg x 10 mg/kg = 700 mg.
Divide the total dose by the concentration of phenytoin to get the volume in milliliters. 700 mg / 50 mg/mL = 14 mL.
Round the volume to the nearest whole number. The nurse should administer 14 mL of phenytoin by IV bolus.
Correct Answer is ["1"]
Explanation
To answer this question, you need to convert the dosage of fentanyl from micrograms (mcg) to milligrams (mg). One milligram is equal to 1000 micrograms, so 50 mcg is equal to 0.05 mg. Then, you need to use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity. In this case, D is 0.05 mg, H is 0.05 mg/mL, and Q is the volume in milliliters. Plugging these values into the formula, you get:
0.05 mg / 0.05 mg/mL x Q
Q = 1 mL
Therefore, the nurse should administer 1 mL of fentanyl per dose.
