Final answer:
Hydromorphone is the correct answer as it is available for both oral and intravenous administration. Morphine and hydrocodone are both primarily administered orally, not just in the manner mentioned in the incorrect options. Oxycodone is primarily for oral use.
Step-by-step explanation:
Which statement is true regarding opiates for pain management? Among the options provided, the true statement is that hydromorphone is available for both oral and intravenous administration. This is because hydromorphone is a medication that can be used both ways to manage pain effectively.
On the other hand, the claim that morphine is available only for oral administration is inaccurate. Morphine can indeed be administered intravenously and in other forms such as oral solutions and extended-release tablets. Additionally, the statement about hydrocodone being only available intravenously is incorrect, as hydrocodone is commonly provided in oral formulations, often in combination with acetaminophen. Lastly, oxycodone is typically prescribed for oral use and does not have an intravenous form for clinical use.
