Final answer:
For embalming with a black eye, using weak fluid and low pressure is advised to prevent further damage to the delicate eye tissues.
Step-by-step explanation:
When embalming in the presence of a black eye, it is generally recommended to use weak fluid with low pressure. This approach minimizes the risk of worsening the condition of the delicate tissues around the eye. Using a strong fluid can dehydrate the tissue further, making it more difficult to restore an acceptable appearance, and high pressure may exacerbate swelling or force fluids into facial tissues, potentially causing distortion.
When a black eye is present during embalming, it is recommended to use weak fluid and low pressure for the best results. Applying strong fluid or high pressure can potentially cause tissue damage and worsen the discoloration and swelling of the black eye.
