No answer is provided
No answer is too low
No answer is too high
3.5
The Correct Answer is D
Choice A reason: This choice is incorrect because it does not provide a numerical answer to the question.
Choice B reason: This choice is incorrect because it does not provide a specific answer to the question. It also implies that there is an answer that is lower than the correct one, which is not true.
Choice C reason: This choice is incorrect because it does not provide a specific answer to the question. It also implies that there is an answer that is higher than the correct one, which is not true.
Choice D reason: This choice is correct because it is the result of dividing the ordered dose (3.5 mg) by the concentration of the vial (1 mg/mL). The formula for calculating the volume to be drawn up is:
Volume = Dose/Concentration
Therefore, the volume to be drawn up is:
Volume = 3.5 mg/(1 mg/mL) = 3.5 mL

Correct Answer is ["0.75"]
Explanation
To calculate the amount of heparin to administer, we can use the following formula:
Amount to administer (mL) = (Desired dose (units) / Available dose (units/mL))
Plugging in the given values:
Amount to administer (mL) = (7,500 units / 10,000 units/mL)
Now, let's solve for the amount to administer:
Amount to administer (mL) = (7,500 / 10,000) = 0.75 mL
So, the nurse should administer 0.75 mL of heparin subcutaneously.
