A nurse is preparing to administer Valium 10 mg PO at bedtime. The amount available is Valium 5 mg tablets.

How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies.

(Do not use a trailing zero)

Choice A rationale
Any competent adult regardless of age or health status can create an advance directive. Advance directives are legal documents that allow individuals to specify their preferences for medical care in case they become unable to communicate their wishes. Competence is the key requirement, meaning the individual must be able to understand and make decisions about their medical care.

Choice B rationale
Only individuals with terminal illnesses is incorrect. While individuals with terminal illnesses may benefit from having an advance directive, it is not a requirement. Advance directives are available to any competent adult, regardless of their health status.
Choice C rationale
Only individuals over the age of 65 is incorrect. Advance directives can be created by any competent adult, regardless of age. It is important for all adults to consider having an advance directive to ensure their medical preferences are known and respected.
Choice D rationale
Only individuals with chronic medical conditions is incorrect. While individuals with chronic medical conditions may benefit from having an advance directive, it is not a requirement.
Advance directives are available to any competent adult, regardless of their health status.

Choice A rationale
Quasi-experimental research involves the manipulation of an independent variable to determine its effect on a dependent variable, similar to experimental research. However, quasi-experimental designs lack random assignment to groups, which can limit the ability to infer causality. Despite this limitation, quasi-experimental designs are valuable for studying causal relationships in real-world settings where random assignment is not feasible.
Choice B rationale

Correlational research examines the relationship between two or more variables without manipulating any variables. It does not involve the manipulation of an independent variable or the use of control groups, making it distinct from quasi-experimental research.
Choice C rationale
Qualitative research focuses on exploring and understanding the meaning and experiences of individuals through methods such as interviews, observations, and content analysis. It does not involve the manipulation of variables or the use of experimental designs, making it distinct from quasi-experimental research.
Choice D rationale
Quantitative research involves the collection and analysis of numerical data to identify patterns, relationships, and trends. While quasi-experimental research is a type of quantitative research, not all quantitative research involves quasi-experimental designs. Quantitative research can also include experimental, correlational, and descriptive designs.
