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

Explanation
Choice A reason: This is incorrect because fentanyl 25 mcg/hr transdermal patch is a common and appropriate dose for chronic pain management. Fentanyl is a potent opioid analgesic that delivers a steady amount of medication through the skin over 72 hours.
Choice B reason: This is incorrect because meloxicam 15 mg PO daily is a standard and safe dose for treating inflammation and pain caused by arthritis. Meloxicam is a nonsteroidal anti-inflammatory drug (NSAID) that reduces the production of prostaglandins, which are involved in inflammation.
Choice C reason: This is correct because regular insulin 8 units subcutaneous before meals is a vague and potentially dangerous prescription. Regular insulin is a short-acting insulin that lowers blood glucose levels by facilitating the uptake of glucose into the cells. The dose of insulin should be individualized based on the client's blood glucose level, carbohydrate intake, and activity level. The nurse should contact the provider for clarification on how to adjust the dose according to the client's needs.
Choice D reason: This is incorrect because docusate sodium 200 mg PO at bedtime is a usual and effective dose for preventing constipation. Docusate sodium is a stool softener that works by increasing the amount of water in the stool, making it easier to pass.
