A nurse is preparing to administer heparin 7,500 units subcutaneous. Available is heparin 10,000 units/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 ["0.75"]
To calculate the volume of heparin (in milliliters) to administer, you can use the following formula:
Volume (mL) = Desired dose (units) / Concentration (units/mL)
In this case, the desired dose is 7,500 units, and the concentration is 10,000 units/mL.
Volume (mL) = 7,500 units / 10,000 units/mL
Volume (mL) = 0.75 mL
So, the nurse should administer 0.75 mL of heparin.

Correct Answer is ["0.04"]
Explanation
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.
