Correct Answer: A

Rationale: The term 'vital statistics' specifically refers to the systematic study of vital events, including births, illnesses, marriages, divorces, separations, and deaths. This field focuses on quantifying and analyzing these essential life events within a population. Choices B, C, and D are incorrect because while they may be related to data collection and analysis, they do not encompass the broad spectrum of vital events covered under the term 'vital statistics.' Morbidity refers to the prevalence of a specific illness or disease within a population, statistics is a more general term for numerical data analysis, and mortality specifically pertains to deaths within a population.

Correct Answer: C

Rationale: The correct answer is C: A deficiency of clotting factor VIII. Hemophilia A is characterized by a lack of clotting factor VIII, which is crucial for blood clotting. This deficiency results in prolonged bleeding. Choices A, B, and D are incorrect. There is no association between Hemophilia A and an excess of red blood cells (Choice A) or an excess of white blood cells (Choice B). Additionally, Hemophilia A specifically involves a deficiency of clotting factor VIII, not both factors VIII and IX (Choice D).

Correct Answer: B

Rationale: The Healthy People initiative is a national agenda that focuses on reducing health disparities and improving the health of all Americans. Choice A is incorrect because the initiative is more about improving health outcomes and access rather than providing healthcare to all citizens. Choice C is not the main goal of the initiative, which is more about public health goals than medical research. Choice D is also not the primary aim of the Healthy People initiative, as it is more focused on setting objectives to improve public health.

Correct Answer: C

Rationale: The correct answer is C because the milk code emphasizes that companies should always acknowledge the superiority of breastmilk over formula. Choice A is incorrect because the focus is not on the public receiving information, but rather on companies recognizing breastmilk's superiority. Choice B is incorrect as it addresses health workers' actions, not the companies' behavior. Choice D is incorrect as the milk code is primarily concerned with regulating companies' practices, not health workers' acceptance of incentives.

Correct Answer: A

Rationale: The correct answer is A: Diabetes. Given the client's Native American ethnicity, high BMI, and vision changes, diabetes is the most crucial condition for the nurse to be aware of in the client's family history. Diabetes is strongly associated with vision problems, especially diabetic retinopathy. Glaucoma (choice B) is a condition that affects the optic nerve and can lead to vision loss but is not as directly linked to the client's BMI and ethnic background. Hypertension (choice C) can also impact vision, but in this case, diabetes takes precedence based on the client's profile. Brain tumor (choice D) is less likely to be related to the client's BMI, ethnicity, and vision changes compared to diabetes.
