Embalming
About 62 of every 150 questions on a NBE Sciences practice exam come from this topic.
What to know
Review case analysis (pre-, intra- and post-embalming), arterial fluid chemistry (preservatives, germicides, modifying agents, dyes, humectants, index and strength), injection and drainage (vessels, pressure and rate, concurrent vs alternate drainage), cavity treatment, special cases (autopsied, trauma, edema, jaundice, decomposition, infants, organ donors), and prep-room safety: formaldehyde exposure limits, PPE and ventilation.

Try a practice question
A white, solid polymer of formaldehyde that slowly releases formaldehyde gas, often found in hardening compounds, is
- Aglutaraldehyde
- Bparaformaldehyde
- Cphenol crystals
- Dsodium borate
Show the answer
paraformaldehyde. Paraformaldehyde is a solid polymer of formaldehyde; it depolymerizes to release formaldehyde, which is why it is used in hardening and cavity-pack powders.
