- B. 50%
- C. 75%
- D. 100%
Correct Answer: A
Rationale: When two carrier parents have children together, they have a 25% chance of having a child who inherits the gene mutation from each parent and who will have the condition, as in autosomal recessive inheritance. The other percentages are incorrect for this inheritance pattern.

What is the nurses best response?
- A. We always get old medical records just in case we need them.
- B. This is just part of the due diligence that we practice here at the clinic.
- C. Your medical information is needed so we can provide the appropriate information and counseling to you.
- D. We need your medical records in case there is something about your medical history that you forget to tell us.
Correct Answer: C
Rationale: Nurses obtain patient consent to obtain medical records to ensure appropriate information and counseling, including risk interpretation, are provided. Vague responses like â??just in case' or â??due diligence' do not adequately explain the need for medical records.
What is the nurses best rationale for this?
- A. Genetic screening is a way to determine the rate of infectious disease in babies during this vulnerable time in their lives.
- B. It is important to screen newborns to determine their future cancer risk and appraise the quality of prenatal care they received.
- C. This is a way to assess your infants risk for illnesses called phenylketonuria (PKU), congenital hypothyroidism, and galactosemia.
- D. This testing is required and you will not be able to refuse it. It usually is free so there is no reason to refuse it.
Correct Answer: C
Rationale: The first aim of genetic testing is to improve management, that is, identify people with treatable genetic conditions that could prove dangerous to their health if left untreated. Genetic screening for PKU, congenital hypothyroidism, and galactosemia allows early intervention. It does not assess infectious disease rates or future cancer risk, and while mandatory, the rationale should focus on the health benefits, not just compliance.
The nurse informs the patient that genetic counseling and prenatal testing should be performed for all pregnant women in which age group?
- A. 18 to 21
- B. 40 and older
- C. 35 and older
- D. 18 and under
Correct Answer: C
Rationale: Women who are 35 years of age or older have an increasing chance of giving birth to infants with chromosomal differences, such as trisomy 21. For this reason, genetic counseling and prenatal testing are recommended for all pregnant women above this age.

This is the primary focus of genetics nursing, not coping, longevity, or physical factors influencing genetics.
