Answer:
Harmful mutations may cause genetic disorders or cancer. A genetic disorder is a disease caused by a mutation in one or a few genes. A human example is cystic fibrosis. A mutation in a single gene causes the body to produce thick, sticky mucus that clogs the lungs and blocks ducts in digestive organs.
Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Natural exposure of an organism to certain environmental factors, such as ultraviolet light and chemical carcinogens (e.g., aflatoxin B1), also can cause mutations.
only a small percentage of mutations cause genetic disorders—most have no impact on health or development. For example, some mutations alter a gene's DNA sequence but do not change the function of the protein made by the gene.
"When a nurse logs into the labor & delivery department in epic as an L&D nurse, the default start-up activity is to follow- up on the list of patients.
L&D nurses have many roles. They are there for their patients from beginning to end during the delivery process. They aid in procedures that need to be performed before labor, like taking vitals. They are there when the baby is delivered and they educate parents on what they should do now they have given birth.
Labor and Delivery Nurses work as main points of support for OBGYNs, monitoring of patient vitals, administering medication, and establishing a trusted line of communication with expectant mothers. A L&D nurse cares for mothers during labor and birth and provides the infant's initial postpartum care under the supervision of a nurse midwife or physicians. "
