Community Health HESI Practice Exam

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: 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.

Correct Answer: B

Rationale: Fasting for at least 12 hours is necessary before a cholesterol and triglyceride test to ensure accurate results by avoiding fluctuations that can occur after eating. Choice A is incorrect because a fat-free diet is not required; fasting is. Choice C is incorrect as it suggests having the test right after eating, which can affect the results. Choice D is incorrect as there is no need to stay at the laboratory for 2 blood samples unless specifically instructed by a healthcare provider.

Correct Answer: C

Rationale: The correct answer is C, Semi-Fowler's. This position helps to reduce intracranial pressure by promoting venous drainage from the head while maintaining adequate oxygenation. Option A, Trendelenburg position, is incorrect as it involves placing the patient with the head lower than the body, which can increase intracranial pressure. Option B, Prone position, is also incorrect as it involves lying on the stomach, which can further elevate intracranial pressure. Option D, Side-lying with head flat, does not provide the same benefits as the Semi-Fowler's position in terms of promoting venous drainage and maintaining oxygenation in a client with increased intracranial pressure.

Correct Answer: B

Rationale: Epidemiology is the study of the distribution and determinants of health-related states in populations. Choice A is incorrect because epidemiology focuses on more than just causes but also on distribution and determinants. Choice C is incorrect as it specifically relates to public health and not just treatment and prevention. Choice D is incorrect as epidemiology is broader than just focusing on the healthcare system and its effectiveness.
