A home health nurse is planning care for a client following a stroke. The nurse plans to interview each member of the family to see how they might help the client progress towards recovery. The nurse is using which of the following approaches to family health?

Rationale:
A. Next-door neighbor is incorrect because while neighbors may observe certain behaviors, they typically do not have consistent access to comprehensive information about a child’s health, behavior, or social risk factors, making them less reliable for identifying at-risk children.

B. Parent is incorrect because although parents provide valuable insight, they may not always recognize signs of victimization or aggressive behavior in their child, and relying solely on parental reporting can lead to underestimation of risk.

C. School nurse is correct because the school nurse regularly interacts with children in a structured environment, has access to health records, observes social interactions, and can identify early warning signs of both victimization and aggression. School nurses are uniquely positioned to help public health departments target prevention and intervention efforts effectively.

D. Pediatric primary care provider is incorrect because although they monitor children’s overall health and development, they may see the child infrequently and have limited observation of day-to-day social interactions and behaviors that indicate risk for violence in the school or community setting.

Rationale:

A. Mucous membranes are a major portal of entry for disease. They line areas such as the respiratory tract, gastrointestinal tract, genitourinary tract, and mouth, and provide a moist environment where pathogens can easily enter the body through inhalation, ingestion, or sexual contact.

B. Eyes are considered a portal of entry because they are lined with mucous membranes (conjunctiva). Pathogens can enter through direct contact, contaminated hands, droplets, or splashes, leading to local or systemic infection.

C. Hair is not a portal of entry. Hair itself does not provide a pathway into the body. While hair can carry microorganisms on its surface, it does not allow pathogens to penetrate the body or access internal tissues.

D. Skin is a portal of entry when it is not intact. Breaks in the skin such as cuts, abrasions, puncture wounds, surgical incisions, IV sites, or insect bites allow microorganisms to enter the body and cause infection.
