A nurse is preparing to administer glyburide 5 mg PO to a client who has gestational diabetes. Available is glyburide 2.5 mg tablets. How many tablets 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 ["2"]
To administer a dose of 5 mg of glyburide when only 2.5 mg tablets are available, the nurse would need to give two tablets. This is because each tablet contains 2.5 mg, and two tablets would equal the prescribed 5 mg dose.

Correct Answer is ["1.7"]
Explanation
To calculate the IV pump setting, first determine the total micrograms of dopamine needed per minute for the newborn: 5 mcg/kg/min * 4.4 kg = 22 mcg/min. Next, convert the available dopamine concentration to micrograms: 200 mg * 1000 mcg/mg = 200,000 mcg. Now, calculate how many micrograms are in each mL of the solution: 200,000 mcg / 250 mL = 800 mcg/mL. Then, determine how many mL are needed per minute to deliver the required 22 mcg/min: 22 mcg/min / 800 mcg/mL = 0.0275 mL/min. Finally, convert this to an hourly rate: 0.0275 mL/min * 60 min/hr = 1.65 mL/hr. Rounded to the nearest tenth, the IV pump should be set to deliver 1.7 mL/hr.
Correct Answer is ["63"]
Explanation
To calculate the infusion rate for the IV pump, the total volume of the IV fluid (250 mL) should be divided by the time over which the infusion is to take place (4 hours). This calculation results in an infusion rate of 62.5 mL/hr. Since the infusion pump cannot be set to a decimal, the rate is rounded to the nearest whole number, which is 63 mL/hr.
