A nurse is obtaining a health history from a client. Which of the following findings should the nurse identify as a modifiable risk factor for developing a disease?
Explanation & Rationale
Choice A reason: Family history is a non-modifiable risk factor, as inherited genetic predispositions (e.g., BRCA mutations for breast cancer) cannot be altered. These genes influence cellular processes like DNA repair, increasing disease risk. While lifestyle mitigates some effects, family history remains a fixed contributor to disease susceptibility. Choice B reason: Age is a non-modifiable risk factor, as chronological aging increases cellular damage, oxidative stress, and telomere shortening, elevating risks for diseases like cancer or cardiovascular conditions. Cumulative exposure to environmental factors exacerbates this, but age itself cannot be changed, making it a fixed risk factor. Choice C reason: Genetics are non-modifiable, as inherited DNA sequences determine disease predisposition (e.g., APOE gene for Alzheimer’s). Genetic mutations affect cellular pathways, like lipid metabolism or tumor suppression, increasing disease risk. While epigenetic modifications occur, core genetic makeup is unchangeable, making it a fixed risk factor. Choice D reason: Sunbathing is modifiable, as reducing UV exposure prevents skin damage and DNA mutations in melanocytes, lowering skin cancer risk. UV radiation causes pyrimidine dimer formation, impairing DNA repair and promoting carcinogenesis. Protective measures like sunscreen or limited exposure directly reduce this risk, making it modifiable.
