A nurse is preparing to administer verapamil 10 mg IV bolus. Available is verapamil injection 5 mg/2 mL. How many mL should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["4"]
To administer verapamil 10 mg IV bolus, the nurse should use the following formula: mL = (mg / mg/mL) x mL. Plugging in the values from the question, we get: mL = (10 / 5) x 2. Simplifying, we get: mL = 4. Therefore, the nurse should administer 4 mL of verapamil injection.

Correct Answer is ["375"]
Explanation
To answer this question, you need to use the formula: rate (mL/hr) = volume (mL) / time (hr). Plug in the given values and you get: rate = 750 / 2.
Simplify and you get: rate = 375.
Therefore, the nurse should set the IV pump to deliver 375 mL/hr.
Correct Answer is ["1.9"]
Explanation
To calculate the dose of dexamethasone, we need to convert the client's weight from pounds to kilograms. One pound is equal to 0.454 kg, so 132 lb is equal to 132 x 0.454 = 59.928 kg. The prescribed dose is 0.5 mg/kg/day, so the daily dose is 0.5 x 59.928 = 29.964 mg. This dose is divided equally every 6 hours, so the dose per administration is 29.964 / 4 = 7.491 mg. The concentration of the drug is 4 mg/mL, so the volume per administration is 7.491 / 4 = 1.873 mL. Rounded to the nearest tenth, the nurse should administer 1.9 mL per dose.
