The Correct Answer is ["0.5"]
To calculate how many tablets of lisinopril 5 mg the nurse should administer to achieve a 2.5 mg dose, divide the desired dose by the dose per tablet:
Number of tablets = Desired dose / Dose per tablet
Number of tablets = 2.5 mg / 5 mg/tablet
Number of tablets = 0.5 tablets

Explanation
To calculate the infusion rate in mL/hr, you can use the following formula:
Infusion Rate (mL/hr) = Total Volume (mL) / Time (hr)
In this case, the total volume is 1,500 mL, and the time is 12 hours:
Infusion Rate (mL/hr) = 1,500 mL / 12 hr = 125 mL/hr
So, the nurse should set the IV pump to deliver 125 mL/hr.
Correct Answer is ["2.4"]
Explanation
To calculate the amount of calcitonin the nurse should administer, follow these steps:
Calculate the client's weight in kilograms: Weight in kilograms = Weight in pounds / 2.2 Weight in kilograms = 130 lb / 2.2 = 59.09 kg (rounded to two decimal places)
Calculate the total units of calcitonin needed: Total units = Weight in kilograms × Dose per kilogram Total units = 59.09 kg × 8 units/kg = 472.72 units
Determine the volume (ml) to administer using the concentration of the available calcitonin: Volume (ml) = Total units needed / Concentration (units/ml) Volume (ml) = 472.72 units / 200 units/ml = 2.36 ml
Rounded to the nearest tenth of a milliliter, the nurse should administer 2.4 ml of calcitonin.
