A natural supplement that can enhance sleep for many people is:.

Choice A rationale:

Indomethacin (Indocin) is a nonsteroidal anti-inflammatory medication (NSAID). It is commonly used to reduce inflammation and relieve pain, making it a suitable choice for pain management in conditions where inflammation plays a role, such as arthritis or musculoskeletal injuries.

Choice B rationale:

Indomethacin is not typically categorized as an adjuvant analgesic. Adjuvant analgesics are medications that are not primarily designed for pain relief but may enhance the effects of analgesics when used in combination.

Choice C rationale:

Indomethacin is not a COX-2 inhibitor. COX-2 inhibitors are a specific class of NSAIDs that target the COX-2 enzyme while sparing COX-1. Indomethacin is a traditional NSAID that inhibits both COX-1 and COX-2.

Choice D rationale:

Indomethacin is not a narcotic analgesic. Narcotic analgesics, also known as opioids, are a separate class of medications used for the management of moderate to severe pain. Indomethacin does not belong to this class and has a different mechanism of action.

Choice A rationale:

Sleeping with the window open for fresh air may not be the best solution in this scenario. While fresh air can be beneficial for sleep, it might not effectively block out the noise from the freeway and the nearby apartment complex. Furthermore, depending on the climate and location, having the window open might lead to discomfort or temperature-related issues.

Choice B rationale:

Performing exercise at bedtime is not a recommended solution for someone experiencing difficulty sleeping due to external noise. Exercise before bedtime can increase alertness and make it even more challenging to fall asleep, especially if it's vigorous exercise. It may exacerbate the problem rather than alleviate it.

Choice C rationale:

Having a couple of drinks at bedtime is not a suitable solution for sleep problems. Alcohol can disrupt sleep patterns and lead to poor-quality sleep. It may help the patient fall asleep initially but can lead to frequent awakenings and a less restful night's sleep.

Choice D rationale:

The correct choice is to wear soft earplugs for sleep. Soft earplugs can effectively reduce or block out external noise, providing a quieter sleep environment. This is a practical and safe solution to address the noise issue in the patient's apartment complex. It promotes better sleep quality without any negative side effects.
