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 will the nurse understand about the childrens possibility of inheriting the gene for the disease?
- A. Each child will have a 25% chance of inheriting the disease.
- B. Each child will have a 50% chance of inheriting the disease.
- C. Each child will have a 75% chance of inheriting the disease.
- D. Each child will have no chance of inheriting the disease.
Correct Answer: B
Rationale: Huntington disease is an autosomal dominant disorder. Autosomal dominant inherited conditions affect female and male family members equally and follow a vertical pattern of inheritance in families. A person who has an autosomal dominant inherited condition carries a gene mutation for that condition on one chromosome pair. Each of that persons offspring has a 50% chance of inheriting the gene mutation for the condition and a 50% chance of inheriting the normal version of the gene.
After the couple receives the results of genetic testing, the nurse should prioritize which of the following?
- A. Secondary illness prevention
- B. Psychosocial support
- C. Gene therapy
- D. Assessing adherence to treatment
Correct Answer: B
Rationale: Following the communication of the findings of genetic testing, it is important that patients receive thoughtful and thorough support to address emotional and psychological impacts. Secondary prevention, gene therapy, or treatment adherence may not be immediately relevant.
What sign should the nurse instruct the woman to look for in the new baby?
- A. Increased urination
- B. Projectile vomiting
- C. Caf-au-lait spots
- D. Xanthoma
Correct Answer: C
Rationale: Physical assessment may provide clues that a particular genetic condition is present. For neurofibromatosis type 1, skin findings like caf-au-lait spots are a key indicator. Increased urination might suggest diabetes, projectile vomiting could indicate pyloric stenosis, and xanthomas are associated with hyperlipidemia, not neurofibromatosis.
What is this foundational genetic test?
- A. The developmental assessment
- B. The family history
- C. The physical assessment
- D. The psychosocial assessment
Correct Answer: B
Rationale: The family history is considered the first genetic test. It is expected that all nurses will know how to use this genetic tool to assess potential genetic risks and patterns of inheritance.
Based on the nurses knowledge of neurofibromatosis, the nurse understands that a single family member has which of the following?
- A. A spontaneous mutation
- B. A germline mutation
- C. A nondisjunction
- D. A monosomy
Correct Answer: A
Rationale: Spontaneous mutations take place in individual oocytes or sperm at the time of conception. These mutations are not inherited in other family members. However, a person who carries the new spontaneous mutation may pass on the mutation to his or her children. Achondroplasia, Marfan syndrome, and neurofibromatosis type 1 are examples of genetic conditions that may occur in a single family member as a result of spontaneous mutation. Germline mutations are passed on to all daughter cells when body cells replicate. Nondisjunction and monosomy are related to chromosomal abnormalities, not single gene mutations like neurofibromatosis.
