Fecal impaction is the formation of a large mass of hard stool in the rectum. While this stool may be too large to pass, loose, watery stool may be able to get by, leading to diarrhea or leakage of fecal material.Fecal impaction is a potential complication of chronic constipation.The development of constipation can be related to a diet low in fiber, limited fluid intake, medication side effects, lack of physical activity, or conditions affecting the colon, rectum or anus.f constipation does not improve and fecal impaction occurs, enemas may be used to soften the stool, which can be broken up and removed manually. Impacted stool may be removed in increments to reduce the risk of injuring the rectum.
Ionic bonding. In ionic bonding, electrons are completely transferred from one atom to another. In the process of either losing or gaining negatively charged electrons, the reacting atoms form ions. The oppositely charged ions are attracted to each other by electrostatic forces, which are the basis of the ionic bond.
The two main types of bonds formed between atoms are ionic bonds and covalent bonds. An ionic bond is formed when one atom accepts or donates one or more of its valence electrons to another atom. A covalent bond is formed when atoms share valence electrons.
