Community Health HESI Practice Exam

Correct Answer: A

Rationale: The correct answer is A: Primary prevention. Primary prevention aims to prevent the occurrence of a disease or injury before it happens. Teaching about hand hygiene to the community helps in preventing infections from occurring in the first place. Choice B, Secondary prevention, involves early detection and treatment to halt or slow the progress of a condition. This would involve screening or early intervention after exposure. Choice C, Tertiary prevention, focuses on managing the disease to prevent complications, recurrence, or deterioration. This would include rehabilitation and monitoring to prevent further complications. Choice D, Quaternary prevention, relates to actions taken to avoid unnecessary interventions or over-medicalization. This usually involves questioning the necessity of certain medical procedures or treatments to prevent harm to patients.

Correct Answer: C

Rationale: Thinning of the skin with loss of elasticity is the physical characteristic of aging that contributes to an increased risk of developing decubitus ulcers. As individuals age, the skin becomes thinner and loses its elasticity, making it more susceptible to damage from pressure, leading to the formation of pressure ulcers. Choices A, B, and D are incorrect as they do not directly contribute to the development of decubitus ulcers in this context.

Correct Answer: A

Rationale: A rapid weight gain of 2 pounds or more in a 48-hour period may indicate fluid retention and worsening heart failure, requiring prompt medical evaluation and intervention. This finding is crucial in managing chronic congestive heart failure as it signifies a potential exacerbation of the condition. Choices B, C, and D are less concerning in this context. Urinating 4 to 5 times a day is within the normal range for most individuals and may not be directly related to heart failure. A significant decrease in appetite may be due to various factors and might not be an immediate cause for concern in heart failure patients. The appearance of non-pitting ankle edema, although related to heart failure, is a more chronic and less urgent symptom when compared to a rapid weight gain, which requires immediate attention.

Correct Answer: B

Rationale: The continuum health model emphasizes ongoing health practices based on past behaviors. Choice A is incorrect as it describes a more binary approach to health. Choice C is incorrect as it focuses on alternative therapies rather than the continuity of health practices.

Correct Answer: A

Rationale: The correct answer is A. BCG vaccine is commonly supplied in freeze-dried form, not in liquid form. Therefore, choices B and C are incorrect. Option D is also incorrect as the vaccine is not supplied in liquid form in a glass ampule.
