Correct Answer: D

Rationale: False imprisonment occurs when a client is physically restrained or confined without legal justification. In this scenario, the nurse restraining the confused and combative client without a physician's order constitutes false imprisonment. Restraints should only be used when necessary to ensure the safety of the client or others, and a physician's order is required to authorize their use. In this case, the nurse acted without proper authorization, making it a violation of the client's rights and false imprisonment. It is essential to follow proper protocols and obtain necessary orders before restraining a client.

Correct Answer: C

Rationale: Toddlers are typically children who are 1 to 3 years old. In this context, the toddlers are children in the age range of 9 to 36 months old. This period is marked by significant cognitive, emotional, and social development as children in this age group start to explore their environments, develop their language skills, begin to understand emotions, and interact with others. It is a crucial stage in a child's development where they start becoming more independent and forming their own identities.

Correct Answer: A

Rationale: Pneumothorax is a condition characterized by the presence of air in the pleural space surrounding the lungs, which can lead to lung collapse. The nurse's assessment findings in a patient with pneumothorax are typically as follows:

Correct Answer: D

Rationale: Knowing the prevalence of diseases provides information on the magnitude of health problems within a community. Prevalence refers to the proportion of individuals in a population who have a particular disease or condition at a specific point in time. By understanding the prevalence rates of different diseases, healthcare providers can better assess the extent of health issues affecting the community. This information is crucial for prioritizing resources and interventions to address the most pressing health concerns effectively. Additionally, prevalence data can guide public health efforts in developing targeted prevention strategies and allocating resources appropriately to improve community health outcomes.

Correct Answer: B

Rationale: Cohort studies are types of epidemiological studies that involve a group of individuals who share a common characteristic or experience and are followed over time to observe the development of a particular health outcome. This type of study is useful in determining the incidence of a disease, identifying risk factors, and studying the natural history of a disease. Cohort studies allow researchers to investigate the relationship between exposure and outcome by following participants forward in time. It helps in establishing causality and is particularly useful for studying rare exposures or outcomes. In contrast, cross-sectional studies involve collecting data from a population at a single point in time, experimental studies involve interventions and control groups, and case-control studies involve comparing individuals with a particular health outcome (cases) to those without the outcome (controls) retrospectively.
