Which of the following best describes the purpose of a literature review in research?

Correct Answer: B

Rationale: The purpose of a literature review is to identify gaps in existing knowledge by reviewing and synthesizing previous research. This helps researchers understand what has been studied, what is missing, and where further research is needed. Choice A is incorrect because a literature review does not introduce new research methods but rather reviews existing ones. Choice C is incorrect because a literature review does not primarily focus on analyzing statistical data but rather on analyzing and synthesizing previous research studies. Choice D is incorrect because a literature review does not describe research findings in detail but rather provides a comprehensive overview of existing literature.

Correct Answer: A

Rationale: Rationale: A nurse should plan to pull the curtain around the client's bed to ensure privacy and maintain dignity during the bathing process. This step promotes the client's comfort and helps maintain their sense of autonomy. It also creates a safe and respectful environment for the client. Washing the client's arms and hands first (B) is not the correct initial step as privacy and dignity should be prioritized. Using a washcloth to wipe the client's eyes from the outer canthus to the inner canthus (C) is incorrect as this can introduce bacteria into the eyes. Filling the bath basin with tap water at a specific temperature (D) is not the initial action to ensure privacy and dignity.

Correct Answer: A

Rationale: The correct answer is A, the death of a goldfish, as a developmental stressor. This event can trigger emotional distress and grief, impacting one's daily functioning. It symbolizes loss and can lead to feelings of sadness and helplessness. In contrast, getting married inside a church (choice B) is typically a joyful event associated with positive emotions and social support, which are not indicative of a developmental stressor. Choices C and D are incomplete and cannot be considered as valid options.

Correct Answer: A

Rationale: The correct answer is A: Use straight catheter. In a coma patient, using a straight catheter is more appropriate because it is a temporary solution for relieving urinary retention without the risks associated with leaving an indwelling catheter in place long-term. Indwelling catheters can increase the risk of infection and discomfort, especially in comatose patients who may not be able to communicate any issues. Additionally, straight catheters are less invasive and can be used as needed, reducing the risk of complications and promoting better patient outcomes.

Correct Answer: A

Rationale: The correct answer is A because playing outside helps boost the child's immune system, increasing resistance to illnesses. Exposure to fresh air and sunlight also promotes overall well-being. Choice B is incorrect as outdoor play is beneficial for health. Choices C and D are incomplete and irrelevant.
