Rationale: In a longitudinal study design, the nurse researcher collects data at multiple points over an extended period of time. This design allows for the examination of changes or trends over time within the same group of participants. It helps in understanding the long-term effects and relationships between variables by tracking the same individuals over a prolonged duration. This design is particularly useful in studying developmental patterns, chronic diseases, or long-term treatment outcomes.

Correct Answer: B

Rationale: In the community setting, the essential record about the patient is the patient's chart. This chart contains all important information about the patient, including medical history, treatment plans, medications, progress notes, and any other pertinent information related to the patient's care. It serves as a crucial document for healthcare providers to track and monitor the patient's health status, facilitate communication among team members, ensure continuity of care, and make informed clinical decisions. The patient's chart is a comprehensive and centralized source of information that guides the delivery of quality care in the community setting.

Correct Answer: B

Rationale: Vestibular neuritis is a condition characterized by the acute onset of severe vertigo, nausea, vomiting, and nystagmus. These symptoms are typically worsened by head movement. Vestibular neuritis is caused by inflammation of the vestibular nerve, which plays a key role in balance and spatial orientation. The classic presentation of these symptoms, along with the absence of hearing loss (which is seen in labyrinthitis), points towards vestibular neuritis as the most likely cause in this scenario. Meniere's disease presents with recurrent episodes of vertigo, hearing loss, tinnitus, and sensation of fullness in the ear. Benign paroxysmal positional vertigo (BPPV) is characterized by brief episodes of vertigo triggered by changes in head position.

Correct Answer: B

Correct Answer: D

Rationale: Public Health Nursing is a specialized field of nursing that focuses on promoting and protecting the health of populations and communities rather than individuals. One of the key principles of Public Health Nursing is the emphasis on health promotion and disease prevention strategies. This involves educating and empowering individuals, families, and communities to adopt healthy behaviors and lifestyles in order to prevent illness and improve overall well-being. Public Health Nurses work to address the root causes of health disparities and advocate for policies and programs that promote the health of entire populations. While providing care to sick individuals may be a component of Public Health Nursing, the primary focus is on preventing illness and promoting health at the community level.
