A nurse is preparing to administer enoxaparin 75 mg subcutaneous once daily to an antepartum client who has a clotting disorder. Available is enoxaparin injection 100 mg/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 administer the correct dose of enoxaparin, which is 75 mg, when the available injection concentration is 100 mg/mL, the nurse needs to calculate the volume of enoxaparin to be administered. The calculation is based on the formula: Volume = Dose / Concentration. So, for a dose of 75 mg and a concentration of 100 mg/mL, the calculation would be 75 mg / 100 mg/mL = 0.75 mL.

Correct Answer is ["150"]
Explanation
To calculate the infusion rate, you would divide the total volume of IV fluid (1,800 mL) by the number of hours over which it is to be infused (12 hr). This calculation gives you 150 mL/hr.
Correct Answer is ["10"]
Explanation
To administer the correct dose of docusate sodium liquid, which is 50 mg per 5 mL, for a total daily prescription of 200 mg, the nurse would need to give two equally divided doses. This means each dose should be 100 mg. To calculate the amount in milliliters for each dose, the nurse would use the following ratio: 50 mg is to 5 mL as 100 mg is to X mL. Solving for X, the calculation is (100 mg * 5 mL) / 50 mg, which equals 10 mL.
