Final answer:
It is true that more time is needed when nurses conduct a health history on older adults. The claim that women were incapable during wartime is false, as women have often taken on significant roles during war. A cohort does consist of diverse subjects, and a positive correlation does not necessarily mean health benefits.
Step-by-step explanation:
When nurses conduct a health history on an older adult, more time is needed to answer questions. This is true because older adults often have more complex health histories, which include a greater number of health conditions, medications, and perhaps difficulties with memory or communication that require additional time to navigate effectively. Proper health assessment of older adults ensures accurate understanding of their health status and the provision of the best care.
Exercise 8.3.2 statement that "Many women found themselves incapable of handling the burdens of war when their husbands and fathers went off to fight" is false. Women have taken extensive roles during wartime, taking on responsibilities at home, in the workforce, and even in military services.
The statement that "A cohort is a group of subjects of different ages, weights, genders, and health statuses" is true. A cohort refers to a group of individuals who are observed over a certain period of time. The diversity within a cohort can be beneficial for certain types of research, where the effects of variables can be compared across different demographic segments.
The statement "A positive correlation means there are health benefits to the variable under investigation" is false. Positive correlation merely indicates a direct relationship between two variables, but it does not imply a beneficial effect. The nature of the correlation, whether beneficial or harmful, needs to be determined from the context of the study.
