PATHOLOGY

Detailed explanation-1: -A patient tells the nurse, “My doctor mentioned that I am homozygous for a certain gene, but I really don’t understand?” What is the best response by the nurse? “You have two identical alleles for the gene."

Detailed explanation-2: -She asks about the need for genetic testing. How does the nurse respond? The nurse is not expected to be the final source of definitive information on genetic issues. However, the nurse can help ensure that the client is appropriately referred to a genetic counselor.

Detailed explanation-3: -The test often can’t determine if a person will show symptoms of a disorder, how severe the symptoms will be, or whether the disorder will progress over time. Another major limitation is the lack of treatment strategies for many genetic disorders once they are diagnosed.

Detailed explanation-4: -A simple blood test of both the partners in a couple can determine the risk of having a child with genetic disorders. Most genetic diseases are known as “recessive disorders, ‘’ which means that each parent needs to pass along one affected gene to the baby in order for the child to be affected.

Detailed explanation-5: -When trying to detect genetic differences between two individuals, one advantage of DNA profiling over whole genome sequencing is that DNA profiling uses just the most variable regions of DNA for comparison. PCR is a technique used to amplify trace amounts of DNA to be used in scientific and forensic analyses.
