Correct Answer: D

Rationale: The correct answer is D because it specifically asks about the exercise practices the older adults participate in, providing detailed information on their current exercise routines. This question is valuable as it helps the nurse understand the type, intensity, and frequency of exercises being performed by the individuals with osteoporosis. Choice A is too broad and doesn't focus on specific exercise practices. Choice B is about personal preferences rather than actual exercise practices. Choice C focuses on the timing of exercise but does not delve into the types of exercises being performed. Thus, D is the most valuable question for gathering pertinent information regarding the exercise practices of older adults with osteoporosis.

Correct Answer: A

Rationale: The correct answer is A: uterine contractions resulting in possible miscarriage. Feverfew is known to stimulate uterine contractions, which can potentially lead to miscarriage in pregnant women. This risk is especially concerning during the first trimester when the uterus is more sensitive to such stimulants. Uterine contractions can increase the risk of premature labor and miscarriage. Reduced fetal growth (choice B), insomnia (choice C), and tiredness the following day (choice D) are not directly associated with feverfew use during pregnancy. It is crucial for the nurse to educate the patient about the potential risk of uterine contractions and advise against the use of feverfew during pregnancy to ensure the safety of both the mother and the fetus.

Correct Answer: A

Rationale: The correct answer is A: Transactional. This type of leader focuses on routine tasks, maintaining order, and ensuring tasks are completed efficiently. In this scenario, the nurse is primarily concerned with daily operational tasks like restocking supplies and checking orders, which align with transactional leadership. Situational leadership focuses on adapting to different situations, transformational leadership inspires change and innovation, and contemporary leadership encompasses various modern leadership styles.

Correct Answer: A

Rationale: The correct answer is A: by licensure and by endorsement. When a nurse holds a license in one state and wishes to practice in another state not participating in a compact agreement, they can typically obtain licensure in the second state through endorsement, which allows them to practice without retaking the licensure examination. This process involves the second state recognizing the nurse's credentials from the original state and granting them a license upon payment of a fee. Choices B, C, and D are incorrect because: B: Mandatory continuing education is a requirement for maintaining licensure but not typically for obtaining initial licensure in a new state. C: Being "grandfathered" usually refers to exempting individuals from new requirements based on previous qualifications, which is not applicable in this scenario. D: Sunset legislation refers to laws that automatically expire unless reauthorized, which is not relevant to the process of obtaining licensure in a new state.

Correct Answer: C

Rationale: The correct answer is C because institutional review boards (IRBs) are responsible for ensuring that research studies involving human subjects do not cause harm. IRBs evaluate the potential risks and benefits of the study to protect participants' rights and well-being. Choice A is incorrect because publication is not within the primary scope of IRBs. Choice B is incorrect as adding to nursing knowledge is not the main focus of IRBs. Choice D is also incorrect as funding approval is typically handled by separate entities and is not the primary role of IRBs.
