A student nurse asks, What is carrier testing? Which response by the nurse educator is most appropriate to answer the student nurse's question?
 
  1. Carrier testing involves testing an asymptomatic individual for carrier status for a genetic condition.
  2. Carrier testing is used to establish a diagnosis of a genetic disorder in an individual who is symptomatic or has had a positive screening test.
  3. Carrier testing is testing to identify a fetus with a genetic disease or condition. Some prenatal testing is offered routinely; other testing may be initiated due to family history or maternal factors.
  4. Carrier testing follows in vitro fertilization (IVF) testing to identify embryos with a particular genetic condition.

Question 2

Which genetic test would be best for the prospective father who recently had a positive screen for a genetic condition?
 
  1. Carrier testing
  2. Predictive testing
  3. Diagnostic testing
  4. Prenatal testing

Answer to Question 1

Correct Answer: 1
Rationale: Carrier testing involves testing an asymptomatic individual for carrier status for a genetic condition. Diagnostic testing is testing to identify a fetus with a genetic disease or condition. Some prenatal testing is offered routinely; other testing may be initiated due to family history or maternal factors. Prenatal testing is testing to identify a fetus with a genetic disease or condition. Some prenatal testing is offered routinely; other testing may be initiated due to family history or maternal factors. Pre-implantation testing follows in vitro fertilization (IVF) testing to identify embryos with a particular genetic condition.

Answer to Question 2

Correct Answer: 3
Rationale: Diagnostic testing is best for an individual who has a positive screen for a genetic disorder. Prenatal testing would be done with a pregnancy. Carrier testing is done with an asymptomatic individual who wishes to know whether he or she is a carrier of a condition. Predictive testing predicts the likelihood of a condition later in life.
