HESI LPN
Community Health HESI Practice Exam
1. A child and his family were exposed to Mycobacterium tuberculosis about 2 months ago. To confirm the presence or absence of an infection, it is most important for all family members to have a
- A. Chest x-ray
- B. Blood culture
- C. Sputum culture
- D. PPD intradermal test
Correct answer: D
Rationale: The PPD (purified protein derivative) intradermal test is the standard screening method for detecting tuberculosis infection. It helps identify individuals who have been infected with Mycobacterium tuberculosis. A chest x-ray (Choice A) is used to assess the extent of active disease, not for screening purposes. Blood culture (Choice B) is not typically used for tuberculosis screening. Sputum culture (Choice C) is used to confirm active tuberculosis in symptomatic individuals, not for initial screening purposes.
2. Under the present system, which of the following is the local government unit responsible for?
- A. Operation and maintenance of health facilities
- B. All of these activities
- C. Implementation of health programs/projects
- D. Delivery of health services
Correct answer: B
Rationale: Under the present system, the local government unit is responsible for all the listed activities. This includes the operation and maintenance of health facilities, implementation of health programs/projects, and delivery of health services. Therefore, choice B, 'All of these activities,' is the correct answer. Choices A, C, and D are incorrect because they are all responsibilities that fall under the local government unit's jurisdiction as well.
3. Epidemiology is directly concerned with which of the following?
- A. factors influencing occurrence and distribution of diseases, defects, disability, or death of groups of individuals
- B. vital health statistics
- C. environmental sanitation
- D. treatment of a communicable disease
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.
4. The healthcare provider is screening children at a local community health clinic for infectious diseases. Which child is at the highest risk for hepatitis B virus?
- A. a newborn
- B. a 3-year-old
- C. a 7-year-old
- D. an 11-year-old
Correct answer: A
Rationale: Newborns are at the highest risk for hepatitis B virus due to potential transmission from the mother. The hepatitis B virus can be transmitted from an infected mother to her baby during childbirth. Children born to mothers infected with hepatitis B are at the highest risk of acquiring the infection. Choices B, C, and D are at lower risk compared to a newborn as they are less likely to have been exposed to the virus during childbirth.
5. The Philippine Family Program seeks to improve and maintain which of the following life-saving measures?
- A. proper spacing of pregnancies
- B. proper timing of pregnancies
- C. fewer pregnancies
- D. all of the above
Correct answer: D
Rationale: The correct answer is D, all of the above. The Philippine Family Program aims to enhance and sustain proper spacing of pregnancies, proper timing of pregnancies, and reducing the number of pregnancies. These measures are essential for promoting maternal and child health, preventing complications, and ensuring better outcomes. Choices A, B, and C are all part of the comprehensive approach taken by the program to safeguard the well-being of families and contribute to overall public health.
