A nurse is preparing to administer exenatide 10 mcg subcutaneous. Available is exenatide 250 mcg/mL. How many ml. should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.04"]
To calculate the volume of exenatide to administer, you can use the following formula:
Volume (mL) = (Desired Dose in mcg) / (Concentration in mcg/mL)
In this case, the desired dose is 10 mcg, and the concentration is 250 mcg/mL. Plugging these values into the formula:
Volume (mL) = 10 mcg / 250 mcg/mL = 0.04 mL
Rounded to the nearest hundredth, the nurse should administer approximately 0.04 mL of exenatide.

Correct Answer is ["83"]
Explanation
To calculate the manual IV flow rate in drops per minute (gtt/min), you can use the following formula:
Flow rate (gtt/min) = (Volume to be infused in mL / Time in minutes) * Drop factor (gtt/mL)
Given:
- Volume to be infused = 250 mL
- Time in minutes = 30 minutes
- Drop factor = 10 gtt/mL
Now, plug these values into the formula:
Flow rate (gtt/min) = (250 mL / 30 min) * 10 gtt/mL
Flow rate (gtt/min) = (8.33) * 10
Flow rate (gtt/min) ≈ 83.3
Rounded to the nearest whole number, the nurse should set the manual IV flow rate to deliver approximately 83 gtt/min.
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.
