Correct Answer: D

Rationale: The correct answer is D: control group. In this study design, Group 3 serves as the control group to compare the effects of music therapy and life review therapy on memory. The control group does not receive any intervention, allowing researchers to isolate the impact of the therapies. This helps determine if any observed improvements in memory are due to the therapies and not other factors. A pilot study (A) is a small-scale preliminary investigation, not a comparison group. A survey (B) is a data collection method, not a comparison group. A needs assessment (C) is used to determine needs, not a comparison group. Thus, the control group is essential in research to establish causal relationships.

Correct Answer: C

Rationale: The correct answer is C: Continual supervision is being provided until the RN determines competency. Rationale: 1. Continual supervision is necessary for the LPN/LVN on the first day to assess their competency. 2. The RN checks frequently throughout the shift to provide support and evaluate the LPN/LVN's performance. 3. Competency must be determined before reducing supervision levels. 4. This level of supervision ensures patient safety and quality care. Incorrect choices: A: There is no supervision - Incorrect because supervision is provided by the RN. B: Periodic inspection - Incorrect as continual supervision is needed for competency assessment. D: Initial supervision - Incorrect as supervision should continue until competency is established. In summary, choice C is correct as continual supervision is crucial for the LPN/LVN on their first day to ensure patient safety and quality care.

Correct Answer: A

Rationale: The correct answer is A because the primary goal for a new graduate nurse in their first job is to successfully complete the orientation process. This is crucial for transitioning from the academic setting to the professional nursing environment. Completing orientation ensures that the nurse is equipped with the necessary knowledge and skills to provide safe and effective patient care. Choice B is incorrect because scheduling interviews immediately after graduation may not allow the nurse enough time to prepare adequately for the interview process. Choice C is incorrect because while self-confidence is important, relying solely on past achievements of peers may not be a sustainable source of confidence in a new work environment. Choice D is incorrect because while work history and letters of recommendation can be valuable, they may not necessarily be the primary focus during the initial stages of a new nurse's career.

Correct Answer: A

Rationale: The correct answer is A: Prehistoric times and the Middle Ages. In prehistoric times, herbs were used as the primary form of medicine. During the Middle Ages, herbal medicine continued to be prevalent due to limited medical knowledge. Other choices are incorrect because B, C, and D do not align with historical periods where herbal medicine was a dominant health practice.
