Community Health HESI Study Guide

1. Epidemiology is directly concerned with which of the following?

Correct answer: A

Rationale: Corrected Rationale: Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations and the application of this study to the control of health problems. It focuses on identifying and understanding the factors that influence the occurrence and distribution of diseases, defects, disability, or death of groups of individuals. Therefore, the correct answer is A. Choice B, vital health statistics, is not the primary focus of epidemiology. While vital health statistics may be used in epidemiological studies, it is not the direct concern of epidemiology. Choice C, environmental sanitation, although important for public health, is not the main focus of epidemiology. Epidemiology is more concerned with the factors influencing disease occurrence and distribution, rather than environmental sanitation. Choice D, treatment of a communicable disease, is more related to clinical medicine rather than epidemiology. Epidemiology is more focused on prevention, control, and understanding the patterns and causes of diseases rather than their treatment.

2. Which facilities are capable of performing minor surgeries and some simple laboratory examinations?

Correct answer: A

Rationale: Secondary level health care facilities are equipped to perform minor surgeries and simple laboratory examinations. Intermediate level care (choice B) refers to a level of care between primary and secondary care, focusing on more complex procedures than minor surgeries. Tertiary level care (choice C) is specialized care that includes services like cardiac surgery and neurosurgery. Primary health care (choice D) is the first point of contact for individuals and is not typically equipped for minor surgeries or complex laboratory tests.

3. A client with chronic congestive heart failure should be instructed to contact the home health nurse if which finding occurs?

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.

4. Tertiary prevention would best be described as:

Correct answer: D

Rationale: Tertiary prevention is the stage of prevention that aims at preventing disability and maximizing the use of remaining capacity. Choice A is more aligned with rehabilitation rather than tertiary prevention. Choice B refers to primary prevention by promoting health and preventing diseases. Choice C focuses on rehabilitation specific to alcohol and drug dependence, which is a form of secondary prevention, not tertiary prevention.

5. Which of the following characteristics apply to 2 to 3-year-old children?

Correct answer: B

Rationale: The correct answer is B. During the age of 2 to 3 years old, children tend to eat very small, nutritious meals throughout the day rather than having three large meals. This behavior is typical for this age group as their appetites fluctuate. Choices A, C, and D are incorrect because while children of this age may start to prefer feeding themselves and begin using a toothbrush with assistance, they typically do not speak in longer sentences at this stage.
