HESI LPN
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. An occupational health nurse is caring for an employee who was exposed to an unknown dry chemical, resulting in a chemical burn. Which of the following interventions should the nurse include in the plan of care?
- A. Irrigate the affected area with running water.
- B. Wash the affected area with antibacterial soap.
- C. Brush the chemical off the skin and clothing.
- D. Leave the clothing in place until emergency personnel arrive.
Correct answer: C
Rationale: The correct intervention for an employee exposed to an unknown dry chemical is to brush off the chemical from the skin and clothing. This helps prevent further skin contact before irrigation can be done. Irrigating the affected area with running water is crucial after brushing off the chemical to minimize the exposure. Washing the affected area with antibacterial soap is not appropriate for chemical burns, as soap can react with certain chemicals and worsen the situation. Leaving the clothing in place until emergency personnel arrive may allow the chemical to continue to harm the skin and should be avoided.
3. The caregiver is teaching parents about accidental poisoning in children. Which point should be emphasized?
- A. Call the Poison Control Center as soon as the situation is identified
- B. Empty the child's mouth in any case of possible poisoning
- C. Have the child move minimally if a toxic substance was inhaled
- D. Do not induce vomiting if the poison is a hydrocarbon
Correct answer: B
Rationale: The correct answer is to emphasize emptying the child's mouth in any case of possible poisoning. This action is crucial to prevent further ingestion of the poisonous substance. Choice A is incorrect because calling the Poison Control Center should be one of the first steps, not waiting until the situation is identified. Choice C is incorrect as moving the child may spread or exacerbate the effects of the toxic substance. Choice D is incorrect because inducing vomiting can be harmful if the poison is a hydrocarbon, as it may lead to aspiration.
4. The client with Parkinson's disease spends over 1 hour to dress for scheduled therapies. What is the most appropriate action for the nurse to take in this situation?
- A. Ask family members to dress the client
- B. Encourage the client to dress more quickly
- C. Allow the client the time needed to dress
- D. Demonstrate methods on how to dress more quickly
Correct answer: C
Rationale: The most appropriate action for the nurse is to allow the client the time needed to dress. Patients with Parkinson's disease may experience difficulties with activities of daily living due to their condition. Allowing the client sufficient time to dress promotes independence and dignity, which are essential aspects of patient-centered care. Asking family members to dress the client may undermine the client's autonomy and self-esteem. Encouraging the client to dress more quickly may lead to frustration and feelings of inadequacy. Demonstrating methods on how to dress more quickly may not address the underlying challenges the client faces and could be perceived as insensitive or dismissive of the client's needs.
5. In planning care for a client with a surgical wound healing by secondary intention, the nurse can anticipate that the client will:
- A. Be at an increased susceptibility for infection
- B. Have a wound that heals more slowly
- C. Experience more pain during the healing process
- D. Require more frequent dressing changes
Correct answer: A
Rationale: Wounds healing by secondary intention involve the gradual filling of the wound with granulation tissue, leading to a higher risk of infection due to prolonged exposure. This makes choice A the correct answer. Choices B and C are incorrect because wounds healing by secondary intention take longer to heal and often result in more pain compared to wounds healing by primary intention. Choice D is also incorrect as wounds healing by secondary intention usually require more frequent dressing changes to prevent infection and promote healing.
