The physician has ordered chromosomal analysis for a newborn baby. Which test does the nurse realize will most likely be performed with this baby?
1. karyotype
2. newborn screen
3. carrier testing
4. preimplantation genetic diagnosis
Question 2From genetic testing, a patient learns that a specific medication can help a developing disease process. What does the nurse understand that genetic testing provided for the patient?
1. biological marker
2. phenotype
3. genotype
4. translocation
Question 3A patient is having difficulty achieving adequate anticoagulation with prescribed doses of warfarin. The nurse realizes that what might be indicated for this patient?
1. genetic testing to determine if the patient metabolizes warfarin slower
2. use of a different anticoagulant
3. review of the patient's diet
4. analysis of the patient's lifestyle
Question 4Through genetic testing, a patient learns that he has an apolipoprotein E2 gene. What should this information suggest to the nurse?
1. The patient is at reduced risk for developing Alzheimer disease.
2. The patient is at increased risk for developing Alzheimer disease.
3. The patient is at risk for contracting malaria.
4. The patient is at risk for developing colorectal cancer.
Question 5A patient has a strong family history of nonpolyposis colorectal cancer. What is the best advice the nurse can give to the patient?
1. Have predispositional genetic testing done to detect the presence of the genetic disorder even though the patient may never develop cancer.
2. Teach the patient the symptoms of colon cancer and suggest a high-fiber diet to prevent cancer.
3. Have regular colonoscopies; if one is abnormal, then predispositional genetic testing is indicated.
4. Have predispositional genetic testing done to detect the presence of colorectal cancer so that treatment can be initiated as early as possible.
