Question 1 of 5
A nurse believes a new mouth care procedure (MCP) is causing more mouth problems than it
Correct Answer: B
Rationale: Rationale for Correct Answer (B): A plausible explanation of how the new MCP could cause harm is crucial for the nurse to confidently present concerns to administration. Without understanding how the MCP could be causing issues, it would be challenging to convince administration of the need for changes. This step ensures that the nurse has a solid basis for their argument and can clearly articulate the potential risks associated with the new procedure. Summary of Incorrect Choices: A: While having specific criteria present can strengthen the case, it is not the primary factor for determining if the MCP is causing problems. C: Relying solely on personal feelings or intuition is not sufficient evidence to support the claim that the MCP is causing harm. D: Observing consistent mouth inflammation is important but does not provide a clear causal relationship between the MCP and the issues, lacking the necessary explanation of how harm is being caused.
Question 2 of 5
In which stage of disease progression would the nurse classify a client who has elevated blood pressure but no symptoms?
Correct Answer: B
Rationale: The correct answer is B: Subclinical stage. In this stage, the client has elevated blood pressure but no symptoms are present. This stage is characterized by the presence of the disease without noticeable symptoms. It is important for the nurse to identify and monitor clients in the subclinical stage to prevent progression to more severe stages. Choice A: Susceptibility stage refers to the stage where the client is at risk of developing the disease but has not yet been affected. Elevated blood pressure without symptoms indicates that the disease has already manifested, ruling out the susceptibility stage. Choice C: Clinical stage would involve the presence of symptoms, which is not the case with the client in question. Therefore, this choice is incorrect. Choice D: Carrier stage typically refers to individuals who harbor a pathogen without showing symptoms themselves, which is not applicable to a client with elevated blood pressure. Hence, this choice is incorrect.
Question 3 of 5
Which disease does the elementary school nurse identify as being spread via airborne transmission?
Correct Answer: A
Rationale: The correct answer is A: Measles. Measles is spread through airborne transmission by respiratory droplets, making it highly contagious. The virus can remain suspended in the air for hours. Influenza (choice B) is also spread through the air but is less contagious than measles. Pertussis (choice C) is primarily spread through respiratory droplets but can also be transmitted through direct contact. Pneumonia (choice D) is not a communicable disease and is typically caused by bacteria or viruses that are not transmitted through the air.
Question 4 of 5
Which manifestation would the nurse include when teaching about mild to moderate food poisoning at a community health fair?
Correct Answer: C
Rationale: The correct answer is C: Dehydration. In mild to moderate food poisoning, dehydration is a common manifestation due to fluid loss from vomiting and diarrhea. Dehydration can lead to complications and requires prompt medical attention. Bloody diarrhea (A) is more indicative of severe cases or specific types of food poisoning. Diarrhea lasting more than 3 days (B) may indicate a more serious infection or underlying condition. Fever less than 102°F (D) is a common symptom, but dehydration is a more critical manifestation that requires immediate focus. Therefore, C is the most appropriate choice to emphasize during community education on mild to moderate food poisoning.
Question 5 of 5
Which of the following statements describes how nursing in the community is more challenging than nursing in an acute care setting?
Correct Answer: D
Rationale: The correct answer is D because controlling the environment in the community is more challenging compared to an acute care setting. In the community, nurses face various environmental factors such as social determinants of health, limited resources, and diverse cultural backgrounds, making it harder to maintain a controlled and predictable environment for patient care. This can impact the delivery of care and outcomes. A: Limited access to information is not specific to community nursing and can also be a challenge in acute care settings. B: More paperwork and forms may be burdensome but do not inherently make community nursing more challenging than acute care. C: This choice is incomplete and does not provide a clear rationale for community nursing being more challenging.
