A community health nurse is working with a group of homeless veterans who have posttraumatic stress disorder (PTSD). Which of the following interventions should the nurse implement?

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: Having the client's daughter communicate information about the procedure is not an action that the nurse should take. The daughter may not be a reliable or accurate interpreter, as she may have limited language skills, lack medical knowledge, or be influenced by her emotions or biases. The nurse should use a qualified interpreter who can ensure the confidentiality, accuracy, and completeness of the communication.

Choice B reason: Arranging for a member of the client's community to interpret the teaching is not an action that the nurse should take. The member of the client's community may not be a qualified or impartial interpreter, as he or she may have a personal or professional relationship with the client, or may have a conflict of interest or a hidden agenda. The nurse should use a professional interpreter who can maintain the boundaries, objectivity, and neutrality of the communication.

Choice C reason: Identifying the client's spoken dialect prior to contacting an interpreter is an action that the nurse should take. This will help the nurse to find an appropriate interpreter who can communicate effectively and respectfully with the client. The nurse should also consider the client's cultural background, preferences, and needs when selecting an interpreter.

Choice D reason: Using professional terminology when providing education prior to the procedure is not an action that the nurse should take. The nurse should use simple and clear language that the client can understand, and avoid using jargon, slang, or idioms that may confuse or offend the client. The nurse should also check the client's comprehension and ask for feedback throughout the communication.
