HESI LPN
Community Health HESI Practice Exam
1. The term 'epidemiology' is best defined as the study of:
- A. The causes of disease
- B. The distribution and determinants of health-related states in populations
- C. The treatment and prevention of disease
- D. The healthcare system and its effectiveness
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.
2. When the Public Health Nurse assesses needs and plans health interventions for a group of people in coordination with other health professionals, they are demonstrating which of the following features of community health nursing:
- A. CHN involves interdisciplinary collaboration
- B. The use of an epidemiologic approach is an essential part of nursing practice
- C. CHN is oriented towards populations
- D. CHN encourages the client's participation in determining their own health
Correct answer: A
Rationale: The correct answer is A. Interdisciplinary collaboration is a fundamental feature of community health nursing. In this scenario, the nurse works with other health professionals to assess needs and plan interventions for a group of people, emphasizing the importance of teamwork and cooperation. Choice B is incorrect because while epidemiology plays a role in community health nursing, it is not the primary focus of this particular situation. Choice C is incorrect as it describes the population-focused nature of community health nursing, which is related but not directly demonstrated in the given scenario. Choice D is incorrect because while client participation is essential in community health nursing, it is not the primary feature demonstrated in the scenario provided.
3. Which of these tests with frequency would the nurse expect to monitor for the evaluation of clients with poor glycemic control in persons aged 18 and older?
- A. A glycosylated hemoglobin (A1c) should be performed during an initial assessment and during follow-up assessments, which should occur at no longer than 3-month intervals
- B. A glycosylated hemoglobin should be obtained at least twice a year
- C. A fasting glucose and a glycosylated hemoglobin should be obtained at 3-month intervals after the initial assessment
- D. A glucose tolerance test, a fasting glucose, and a glycosylated hemoglobin should be obtained at 6-month intervals after the initial assessment
Correct answer: A
Rationale: Glycosylated hemoglobin (A1c) testing every 3 months is recommended for clients with poor glycemic control to monitor their average blood sugar levels and adjust treatment as necessary. Choice A is correct as it aligns with the guideline of performing A1c testing every 3 months. Choice B is incorrect because testing at least twice a year may not provide adequate monitoring for clients with poor glycemic control. Choice C is incorrect as it only mentions testing at 3-month intervals without specifying the importance of A1c testing. Choice D is incorrect as it includes unnecessary tests like glucose tolerance test and does not emphasize the importance of more frequent A1c monitoring for clients with poor glycemic control.
4. A client with asthma has low-pitched wheezes present on the final half of exhalation. One hour later the client has high-pitched wheezes extending throughout exhalation. This change in assessment indicates to the nurse that the client
- A. Has increased airway obstruction
- B. Has improved airway obstruction
- C. Needs to be suctioned
- D. Exhibits hyperventilation
Correct answer: A
Rationale: The correct answer is A: 'Has increased airway obstruction.' High-pitched wheezes extending throughout exhalation indicate a worsening airway obstruction, leading to increased resistance in the airways. Low-pitched wheezes present on the final half of exhalation may suggest some level of obstruction, but the change to high-pitched wheezes throughout exhalation indicates a progression in the obstruction. Choice B is incorrect as the change in wheeze characteristics signifies deterioration rather than improvement. Choice C is incorrect as suctioning is not indicated based on the wheeze assessment findings. Choice D is incorrect as hyperventilation does not typically present with wheezes and is not supported by the information provided.
5. A client presents at a community-based clinic with complaints of shortness of breath, headache, dizziness, and nausea. During the assessment, the nurse learns that the client is a migrant worker who often uses a gasoline-powered pressure washer to clean equipment and farm buildings. Which type of poisoning is the most likely etiology of this client's symptoms?
- A. asbestos
- B. silica dust
- C. histoplasmosis
- D. carbon monoxide
Correct answer: D
Rationale: The client's symptoms of shortness of breath, headache, dizziness, and nausea are indicative of carbon monoxide poisoning, which can result from exposure to gasoline-powered equipment like pressure washers. Asbestos (Choice A) exposure would typically present with respiratory issues and cancer but not the rapid onset of symptoms described. Silica dust (Choice B) exposure is associated with respiratory conditions like silicosis, not the multisystem symptoms in the scenario. Histoplasmosis (Choice C) is a fungal infection that primarily affects the lungs and is not related to the client's exposure to a gasoline-powered pressure washer.
