A nurse is teaching a class about the steps of the inflammatory response. The nurse should include that which of the following is the first step in the inflammatory response?
Inflammatory cells are activated
Release of inflammatory markers, such as C-reactive protein
Inflammatory pathways are triggered
Recognition of harmful stimuli by patern receptors on cell surfaces
The Correct Answer is D
The first step in the inflammatory response is the recognition of harmful stimuli by pattern recognition receptors (PRRs) on the surfaces of various cells, including immune cells and non-immune cells. PRRs recognize specific patterns associated with pathogens, damage-associated molecular patterns (DAMPs), and pathogen-associated molecular patterns (PAMPs), among others. This recognition leads to the activation of signaling pathways that promote the recruitment and activation of immune cells and the release of inflammatory mediators, such as cytokines and chemokines.
Once the PRRs recognize the harmful stimuli, inflammatory cells are activated, including neutrophils, macrophages, and dendritic cells. These cells then release inflammatory markers, such as C-reactive protein, which promote the recruitment and activation of more immune cells and further amplify the inflammatory response. Inflammatory pathways are also triggered, leading to the production of various inflammatory mediators and the activation of transcription factors that regulate the expression of genes involved in the inflammatory response.

Correct Answer is B
Explanation
According to the CDC, practicing hand hygiene is a simple yet effective way to prevent infections in healthcare settings. Hand hygiene means cleaning your hands by washing with soap and water or using an alcohol-based hand sanitizer. When washing hands with soap and water, healthcare workers should wash their hands for at least 20 seconds1. Holding their hands below the elbows while rinsing off soap is a proper hand hygiene technique
Correct Answer is C
Explanation
Answer: C. Place a surgical mask on the client when they leave their room.
Rationale:
A) Wear a surgical mask when within 0.6 m (2 ft) of the client.
While it is necessary to wear a surgical mask when in close proximity to a client on droplet precautions, the distance specified (0.6 m or 2 ft) is less than the standard recommended distance of 1 meter (3 feet). Therefore, this option is not fully aligned with best practices.
B) Move the client to a positive airflow room.
Positive airflow rooms are typically used for clients with immunosuppression or those who need protection from airborne pathogens, not for those on droplet precautions. This action is not appropriate for a client requiring droplet precautions.
C) Place a surgical mask on the client when they leave their room.
This action is appropriate and essential to minimize the risk of transmission of infectious agents to others when the client is moving outside their isolation area. The client wearing a mask is a key part of droplet precautions.
D) Remove fresh flowers from the client’s room.
While it may be necessary to remove fresh flowers in certain cases (such as for neutropenic clients), this is not specifically related to droplet precautions. Droplet precautions focus primarily on respiratory secretions and do not directly involve the presence of flowers.
