Correct Answer is ["0.8"]

Explanation

To calculate the volume of enoxaparin to administer, you would use the formula: Volume = Dose / Concentration. Here, the dose required is 30 mg, and the concentration available is 40 mg/mL. Plugging the values into the formula gives you: Volume = 30 mg / 40 mg/mL = 0.75 mL. Therefore, the nurse should administer 0.8 mL when rounded to the nearest tenth.
