Correct Answer is A
Explanation
Administer one half tablet. To find the amount of tablets to administer, use the formula: (ordered dose / available dose). In this case, (250 mg / 500 mg) = 0.5 tablet. Since the tablet is pre-scored, it can be easily split in half.
Metformin is a medication that belongs to a class of drugs called biguanides. It is used to treat type 2 diabetes by lowering blood sugar levels and improving insulin sensitivity. Metformin works by reducing the amount of glucose produced by the liver and increasing the uptake of glucose by the muscles and other tissues.
Metformin can also help prevent or delay the onset of diabetes complications, such as heart disease and kidney damage.
Correct Answer is D
Explanation
First, we need to calculate the total dose of esmolol required per minute: Total dose = Weight x Dose x 60 minutes
Total dose = 65 kg x 200 mcg/kg/min x 60 minutes Total dose = 780,000 mcg/min
Next, we need to convert the dose to milligrams (mg):
780,000 mcg/min = 780 mg/min
The concentration of the esmolol solution is 2,500 mg in 250 mL or 10 mg/mL. To deliver 780 mg/min at a concentration of 10 mg/mL, we need to infuse: Infusion rate = Total dose / Concentration
Infusion rate = 780 mg/min / 10 mg/mL Infusion rate = 78 mL/min
Rounding to the nearest whole number, the answer is D. 78 mL/hr.
Therefore, the nurse should calculate an infusion rate of 78 mL/hr to deliver the required dose of esmolol to the patient.
