Community Health HESI Practice Exam
1. Which bioterrorism agent poses a high risk for use as a potential biological weapon due to its ability to be readily transmitted through several portals of entry?
- A. Anthrax.
- B. Smallpox.
- C. Botulism.
- D. Tularemia.
Correct answer: A
Rationale: The correct answer is Anthrax. Anthrax is a high-risk bioterrorism agent because it can be readily transmitted through multiple portals of entry such as inhalation, ingestion, or skin contact. This makes it a significant concern for use as a biological weapon. Smallpox, though highly contagious, is not known for multiple portals of entry like Anthrax. Botulism is a potent toxin but is not as easily transmissible through various routes as Anthrax. Tularemia, while a serious bacterial infection, does not have the same ease of transmission through multiple portals of entry as Anthrax.
2. A client was admitted with a diagnosis of pneumonia. When auscultating the client's breath sounds, the nurse hears inspiratory crackles in the right base. Temperature is 102.3 degrees Fahrenheit orally. What finding would the nurse expect?
- A. Flushed skin
- B. Bradycardia
- C. Mental confusion
- D. Hypotension
Correct answer: C
Rationale: The correct answer is C: Mental confusion. In this scenario, the client's high fever and pneumonia diagnosis indicate an infection. Infections, especially in older adults, can lead to mental confusion due to the body's systemic response to the infection. Flushed skin (choice A) is more commonly associated with fever but does not specifically relate to the client's condition. Bradycardia (choice B) and hypotension (choice D) are less likely findings in a client with pneumonia and a high fever; instead, tachycardia and increased blood pressure are more commonly seen in response to infection.
3. 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.
4. The Food Fortification Act of 2000 provides for the mandatory fortification of staple foods, which includes:
- A. Flour with iron
- B. Refined sugar with iron
- C. Cooking oil with vitamin A
- D. Rice with vitamin A
Correct answer: A
Rationale: The correct answer is A: Flour with iron. The Food Fortification Act of 2000 mandates the fortification of flour with iron to address iron deficiency in the population. Refined sugar is not typically fortified with iron, making choice B incorrect. While cooking oil fortification with vitamin A is common in some regions, it is not specified under the Food Fortification Act of 2000, rendering choice C incorrect. Similarly, rice fortification with vitamin A is not included in the mandatory fortification list according to the act, making choice D incorrect.
5. The nurse is reviewing a depressed client's history from an earlier admission. Documentation of anhedonia is noted. The nurse understands that this finding refers to:
- A. Reports of difficulty falling and staying asleep
- B. Expression of persistent suicidal thoughts
- C. Lack of enjoyment in usual pleasures
- D. Reduced senses of taste and smell
Correct answer: C
Rationale: The correct answer is C: Lack of enjoyment in usual pleasures. Anhedonia is the inability to feel pleasure in normally pleasurable activities. Choice A, reports of difficulty falling and staying asleep, is more indicative of insomnia rather than anhedonia. Choice B, expression of persistent suicidal thoughts, is related to suicidal ideation and not anhedonia. Choice D, reduced senses of taste and smell, is more associated with disturbances in the sense of taste and smell, not anhedonia.
