A nurse is working in a shelter following a disaster. Which of the following is the priority action for the nurse to take?

Choice A reason: A humidifier should be placed beside the child's bed is not the information that the nurse should include, as it is not relevant to pertussis. Pertussis, or whooping cough, is a bacterial infection that causes severe coughing spells, difficulty breathing, and a characteristic whooping sound. A humidifier may help with other respiratory conditions, such as bronchitis or asthma, but it does not affect pertussis.

Choice B reason: Household contacts will receive prophylactic antibiotics is the information that the nurse should include, as it is an important measure to prevent the spread of pertussis. Pertussis is highly contagious and can be transmitted through respiratory droplets from coughing or sneezing. Household contacts, especially those who are not fully vaccinated or have a weakened immune system, are at risk of contracting pertussis from the child. Prophylactic antibiotics, such as azithromycin or erythromycin, can reduce the risk of infection and complications.

Choice C reason: Transmission will be prevented because of herd immunity is not the information that the nurse should include, as it is not true for pertussis. Herd immunity is the protection that occurs when a large proportion of the population is immune to a disease, either through vaccination or natural infection. Herd immunity can reduce the transmission of some diseases, such as measles or polio, but it is not effective for pertussis. This is because pertussis immunity wanes over time, and the current vaccines do not provide long-lasting protection. Therefore, even vaccinated people can get or spread pertussis.

Choice D reason: The child is most contagious after the rash develops is not the information that the nurse should include, as it is not true for pertussis. Pertussis does not cause a rash, unlike some other childhood diseases, such as measles or chickenpox. The child is most contagious during the first two weeks of the illness, when the symptoms are similar to a common cold. The coughing spells usually start after the first week and can last for several weeks or months.

Choice A reason: Blood pressure screening is not the first thing that the nurse should perform, as it is a physical assessment that can be done later in the visit. Blood pressure screening is important to monitor the client's cardiovascular health and risk of hypertension, but it is not a priority for the initial visit.

Choice B reason: Mental status examination is not the first thing that the nurse should perform, as it is a psychological assessment that can be done later in the visit. Mental status examination is important to evaluate the client's cognitive, emotional, and behavioral functioning and identify any mental health issues, but it is not a priority for the initial visit.

Choice C reason: Review of the neighborhood is the first thing that the nurse should perform, as it is an environmental assessment that can provide valuable information about the client's living conditions, safety, and resources. Review of the neighborhood is important to identify any potential hazards, barriers, or needs that may affect the client's health and well-being, and to plan appropriate interventions and referrals.

Choice D reason: Family history is not the first thing that the nurse should perform, as it is a genetic and social assessment that can be done later in the visit. Family history is important to determine the client's risk of inheriting or developing certain diseases, and to understand the client's family dynamics and support system, but it is not a priority for the initial visit.
