A nurse is preparing to administer cyclosporine 5 mg/kg IV bolus to a client who weighs 143 lb. Available is cyclosporine injection 50 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero)
The Correct Answer is ["6.5"]
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.

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 ["1.5"]
Explanation
To calculate the amount of phenobarbital injection needed for each dose after the initial dose, we need to divide the prescribed dose (200 mg) by the concentration of the injection (130 mg/mL). This gives us:
200 mg / 130 mg/mL = 1.538 mL
To round this to the nearest tenth, we look at the hundredths place and see that it is 3, which is less than 5, so we round down and drop the rest of the digits. This gives us:
1.5 mL
Therefore, the nurse should administer 1.5 mL of phenobarbital injection per dose after the initial dose.
