A nurse is preparing to administer phenytoin. Which of the following information should the nurse identify as correct according to the medication label?
The medication is for IV administration.
The total amount available per container is 4 mL.
The nurse should avoid shaking the medication.
The medication should not be stored below 30 C(86 F)
The Correct Answer is B
A. The medication is for IV administration: This cannot be assumed unless the label specifically states “for intravenous use.” Phenytoin comes in multiple formulations (oral suspension, tablets, IV), so route must be verified.
B. The total amount available per container is 4 mL: This is label-specific information. If the label indicates that each vial contains 4 mL, this is a factual and critical point to ensure accurate dosing.
C. The nurse should avoid shaking the medication: While some medications (e.g., suspensions) should not be shaken vigorously, phenytoin IV solution is not a suspension, and this instruction may not apply to all forms.
D. The medication should not be stored below 30°C (86°F): This is incorrect. Phenytoin should be stored at controlled room temperature, typically 20°C to 25°C (68°F to 77°F), and protected from excessive heat or cold.

Correct Answer is ["25"]
Explanation
To calculate the IV flow rate in gtt/min, use the formula: (mL/hr x drop factor) / 60 min. Plug in the values: (100 mL/hr x 15 gtt/mL) / 60 min = 25 gtt/min. Round to the nearest whole number: 25 gtt/min.
Correct Answer is ["6.5"]
Explanation
To answer this question, we need to perform some calculations. First, we need to convert the client's weight from pounds to kilograms. We can do this by dividing 143 by 2.2, which gives us 65 kg. Next, we need to multiply the dose of cyclosporine by the client's weight to get the total amount of medication needed. We can do this by multiplying 5 mg/kg by 65 kg, which gives us 325 mg. Finally, we need to divide the total amount of medication by the concentration of the injection to get the volume to administer. We can do this by dividing 325 mg by 50 mg/mL, which gives us 6.5 mL. Therefore, the nurse should administer 6.5 mL of cyclosporine injection to the client.
