A forensic nurse is using the epidemiological triangle to explain factors that contribute to violent behavior. Which of the following factors should the nurse identify as an environmental factor in the epidemiological triangle?

A. Loud volume of the television set. While a loud television may indicate hearing impairment, it does not pose an immediate safety risk. The nurse should assess the client’s hearing and provide recommendations if needed, but addressing environmental hazards that increase the risk of falls takes priority.

B. Wall-to-wall carpet in the living room. Unlike loose rugs, wall-to-wall carpeting reduces the risk of tripping and slipping. It provides better traction for walking, making it a safer flooring option for older adults compared to hard surfaces or throw rugs.

C. Low chairs without armrests. Low chairs make it difficult for older adults to stand up, increasing the risk of falls. The absence of armrests further reduces stability and support when rising from a seated position. Recommending higher chairs with armrests can enhance mobility and prevent injuries.

D. Use of indirect lighting. Soft, indirect lighting can help reduce glare and improve comfort, but it may not necessarily create safety concerns. However, inadequate lighting in critical areas, such as hallways or staircases, should be assessed to prevent falls.

A. Rubella: This disease is primarily spread through respiratory droplets, requiring standard precautions for management. It is important for nurses to understand that while rubella can be contagious, airborne precautions are not necessary for this condition.

B. Pertussis: Also known as whooping cough, pertussis is transmitted through respiratory droplets, which necessitates droplet precautions rather than airborne precautions. Understanding the mode of transmission helps healthcare workers implement the appropriate level of precautions to prevent the spread of infection.

C. Influenza: Influenza is primarily transmitted through respiratory droplets. Although droplet precautions are necessary when caring for patients with influenza, airborne precautions are not required. Knowledge of these distinctions is essential for nurses to ensure effective infection control measures.

D. Varicella: Varicella, or chickenpox, is classified as an airborne disease because it spreads through respiratory droplets and direct contact with the rash. Airborne precautions are necessary to prevent transmission, especially in healthcare settings where vulnerable populations may be present. Understanding the specific precautions for airborne diseases is crucial for maintaining patient and staff safety.
