HESI LPN
HESI Fundamental Practice Exam
1. A healthcare professional is admitting a client who has tuberculosis. Which of the following types of transmission precautions should the healthcare professional plan to initiate?
- A. Contact
- B. Droplet
- C. Airborne
- D. Protective environment
Correct answer: C
Rationale: Tuberculosis is transmitted through airborne particles, so airborne precautions are necessary to prevent the spread of the disease. Airborne precautions (Choice C) involve measures such as negative pressure rooms and N95 respirators to prevent the transmission of infectious agents that remain infectious over long distances when suspended in the air. Contact precautions (Choice A) are used for diseases that spread through direct contact with the patient or their environment. Droplet precautions (Choice B) are for diseases transmitted through respiratory droplets, typically over short distances. Protective environment (Choice D) is used for clients who are immunocompromised to protect them from environmental pathogens, not for diseases like tuberculosis that spread through the air.
2. A nurse is caring for a client with major depressive disorder who is withdrawn and refuses to participate in group activities. What is the best nursing intervention?
- A. Encourage the client to attend at least one group session.
- B. Respect the client's wish to remain isolated.
- C. Arrange for individual therapy sessions.
- D. Offer the client a list of activities to choose from.
Correct answer: A
Rationale: Encouraging the client to attend at least one group session is the best nursing intervention in this scenario. By gently encouraging participation, the nurse can help the client start to engage with others, which may gradually improve their mood and social interaction. Choice B, respecting the client's wish to remain isolated, may further exacerbate the client's withdrawal and depression by reinforcing avoidance behavior. Choice C, arranging for individual therapy sessions, can be beneficial but may not address the specific need for social interaction. Choice D, offering a list of activities to choose from, does not directly address the client's difficulty in participating in group activities and may not provide the necessary support in overcoming social withdrawal.
3. Which of the following statements is true of mutations?
- A. Mutations can only occur by chance.
- B. Mutations produce sperm and ova cells.
- C. Mutations occur through radiation or other environmental influences.
- D. Mutations help adenine combine with guanine to form the single spiral structure of DNA.
Correct answer: C
Rationale: The correct answer is C. Mutations can occur due to environmental influences such as radiation, chemicals, or other external factors, leading to changes in the DNA sequence. Choice A is incorrect because mutations can also occur due to errors in DNA replication, not solely by chance. Choice B is incorrect as mutations affect the DNA sequence itself, not the production of specific cells. Choice D is incorrect because mutations involve changes in the DNA sequence and do not specifically involve the formation of the DNA structure.
4. A client with a diagnosis of hypothyroidism is prescribed levothyroxine (Synthroid). What is the most important instruction the nurse should provide?
- A. Take the medication in the morning on an empty stomach
- B. Take the medication with food
- C. Report any symptoms of hyperthyroidism
- D. Do not discontinue the medication abruptly
Correct answer: C
Rationale: The correct answer is C: 'Report any symptoms of hyperthyroidism.' Symptoms of hyperthyroidism, such as palpitations or tremors, may indicate an excessive dose of levothyroxine and should be reported to the healthcare provider for proper adjustment of the medication. Choice A is incorrect because levothyroxine is usually taken in the morning on an empty stomach to maximize absorption. Choice B is incorrect because taking levothyroxine with food can interfere with its absorption. Choice D is incorrect because discontinuing levothyroxine abruptly can lead to a worsening of hypothyroidism symptoms.
5. Which of the following is an example of a positive outcome for one of the Leading Health Indicators of Healthy People 2020?
- A. A community has adopted a no smoking policy.
- B. A rural community has a public transportation system.
- C. The high school dropout rate has decreased by 15%.
- D. A county has decreased its divorce rate by 10%.
Correct answer: A
Rationale: The correct answer is A. A community adopting a no smoking policy is a positive outcome for the Leading Health Indicators of Healthy People 2020 as it promotes a healthier environment by reducing exposure to secondhand smoke and decreasing smoking-related illnesses. Choices B, C, and D do not directly align with the goals of the Leading Health Indicators. While public transportation and reduced dropout rates are beneficial for community well-being, they are not specific examples of Leading Health Indicators. Decreasing divorce rates, while potentially beneficial for family stability, is not a focus area of the Leading Health Indicators.
