A female middle adult client tells a nurse that she tested positive for a mutant BRCA1 gene.
The nurse should recognize that the client is at an increased risk for which of the following situations?
Developing thyroid cancer.
Delivering a child who has Down syndrome.
Developing breast cancer.
Developing Alzheimer's disease.
The Correct Answer is C
Choice A rationale
A mutant BRCA1 gene is not associated with an increased risk of thyroid cancer. Thyroid cancer risk factors include radiation exposure and family history, but not the BRCA1 mutation.
Choice B rationale
The BRCA1 gene mutation does not increase the risk of Down syndrome in offspring. Down syndrome is related to chromosomal abnormalities, not the BRCA1 gene mutation.
Choice C rationale
The BRCA1 gene mutation significantly increases the risk of breast cancer, often at an early age. It is a key factor in hereditary breast cancer syndromes.
Choice D rationale
The BRCA1 gene mutation is not linked to an increased risk of Alzheimer's disease. Alzheimer's is associated with genetic factors like the APOE gene, not BRCA1.

Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"B"}
Explanation
Systemic lupus erythematosus often causes photosensitivity, which is an increased sensitivity to sunlight, leading to skin rashes and other reactions. Additionally, chronic fatigue is a common symptom in individuals with SLE, as described by the progressive fatigue that the client has been experiencing. Weight loss and hypoglycemia are not directly related to the common complications of SLE mentioned in the exhibits.
Correct Answer is B
Explanation
Choice A rationale
DIC is not controllable with lifelong heparin usage. Heparin may be used to manage DIC, but it is not a permanent solution, and the underlying cause of DIC must be addressed.
Choice B rationale
DIC is caused by abnormal coagulation involving fibrinogen. It is characterized by widespread activation of the clotting cascade, leading to both clot formation and bleeding due to consumption of clotting factors and platelets.
Choice C rationale
DIC is not a genetic disorder involving a vitamin K deficiency. It is an acquired condition resulting from severe illnesses or injuries that trigger abnormal clotting and bleeding processes.
Choice D rationale
DIC is not characterized by an elevated platelet count. Instead, it involves thrombocytopenia due to the consumption of platelets in widespread clotting, leading to a decreased platelet count.
