Final answer:
The appropriate approach for embalming non-autopsied remains refrigerated for 24 hours is a delayed arterial injection, allowing the body to warm slightly before the process.
Step-by-step explanation:
The question regards the best approach to take when embalming non-autopsied remains that have been refrigerated for 24 hours. The correct approach would be a delayed arterial injection. This technique involves waiting until the body has had time to warm slightly, minimizing the potential adverse effects of refrigeration on the embalming process, such as firming of tissue which can impede fluid distribution and increase the risk of intravascular resistance. When the body is partially warmed (not fully to room temperature), a arterial embalming can be started with warmed embalming fluids to help counteract the effects of refrigeration and ensure proper preservation and disinfection.
