Based on the husbands statement, what nursing diagnosis most likely applies to the wife?
- A. Situational low self-esteem related to reluctance to have genetic testing
- B. Powerlessness related to results of genetic testing
- C. Ineffective health maintenance related to reluctance to have genetic testing
- D. Anxiety related to possible results of genetic testing
Correct Answer: D
Rationale: The husband's statement suggests that the wife is anxious or fearful of obtaining bad news from genetic testing. This aligns with a nursing diagnosis of anxiety, rather than low self-esteem, powerlessness, or ineffective health maintenance, which are less directly supported by the statement.

Which of the following actions is most consistent with this role?
- A. Planning treatment modalities for diseases that have patterns of inheritance
- B. Processing tissue samples to obtain genetic information
- C. Choosing options for patients after genetic testing has been completed
- D. Informing patients about the ethics of genetics and genomic concepts
Correct Answer: D
Rationale: Nurses inform patients about genetics and genomic concepts, including ethical considerations, and value the privacy and confidentiality of such information. Nurses do not typically plan medical treatments, process tissue samples, or make choices for patients.
What is the chance that this couple will have a child with six toes?
- A. 25%
- 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.
The nurse should recognize that this patients health status may be the result of what phenomenon?
- A. X-linked inheritance
- B. Autosomal recessive inheritance
- C. Autosomal dominant inheritance
- D. Multifactorial inheritance
Correct Answer: D
Rationale: Many birth defects and common health conditions, such as heart disease, high blood pressure, cancer, osteoarthritis, and diabetes, occur as a result of interactions of multiple gene mutations and environmental influences. Thus, they are called multifactorial or complex conditions. X-linked, autosomal recessive, and autosomal dominant conditions are caused by single gene mutations, not multiple gene interactions.
This nurse has consequently completed the first step in what process?
- A. Establishing the pattern of inheritance
- B. Influencing the clients genetic future
- C. Answering the clients genetic questions
- D. Answering the clients relational questions
Correct Answer: A
Rationale: Nursing assessment of the patient's health includes obtaining and recording family history information in the form of a pedigree. This is a first step in establishing the pattern of inheritance. It does not directly answer questions or influence genetic outcomes.
What knowledge would influence your nursing considerations for genetic testing?
- A. What genetic tests predict the patients husbands risk of Alzheimers disease
- B. What actions the geneticist has recommended for treating the disease
- C. The genetic bases of adult-onset conditions such as Alzheimers disease
- D. Whether any of the patients peers have Alzheimers disease
Correct Answer: C
Rationale: Knowledge of adult-onset conditions and their genetic bases (i.e., mendelian versus multifactorial conditions) influences the nursing considerations for genetic testing and health promotion. The husband's risk or peers' conditions are not relevant, and geneticists do not typically make treatment recommendations.
