Which of the following must be maintained at a constant temperature when storing an un-embalmed body?

Maintaining an un-embalmed body at a temperature of less than 40 degrees Fahrenheit is crucial for ensuring the preservation of the body until final arrangements can be made. This temperature helps to slow down the decomposition process significantly, thereby preventing the rapid growth of bacteria and microorganisms that thrive in warmer environments.

Furthermore, legal and ethical standards dictate that funeral homes and similar establishments must adhere to specific guidelines regarding the storage of un-embalmed bodies to ensure the dignity and respect owed to the deceased. Keeping the body at this regulated temperature also assists in maintaining hygienic conditions within the storage area and helps funeral professionals manage the preparation process effectively without compromising public health.

While there are other temperature ranges presented, they do not provide the same level of preservation as maintaining the temperature below 40 degrees Fahrenheit. Ranges such as above this threshold could lead to faster decomposition and associated issues.
