A nurse is reinforcing teaching with a group of adolescents about safety. Which of the following information should the nurse include in the teaching?

Choice A rationale:
Contact precautions are indicated when the client has a condition that can be easily transmitted through direct contact with the client or their environment. Measles, which is an airborne disease, requires more stringent precautions due to its mode of transmission.
Choice B rationale:
The correct choice. Measles is spread through airborne particles, making airborne precautions necessary. These precautions include placing the client in a negative pressure room, wearing appropriate respiratory protection (e.g., N95 mask), and ensuring that healthcare providers are properly protected from inhaling infectious particles.
Choice C rationale:
A protective environment is a specialized form of isolation used for clients with compromised immune systems, such as those undergoing stem cell transplants. It involves maintaining a sterile environment to prevent the introduction of pathogens. This level of precautions is not applicable to clients with measles.
Choice D rationale:
Droplet precautions are appropriate for diseases that are transmitted through respiratory droplets generated by coughing, sneezing, or talking. Measles, however, is transmitted through smaller airborne particles that can remain suspended in the air for longer periods, making airborne precautions the most suitable choice.

Choice A rationale:
A 2 cm scalp laceration, while a concern, is not the nurse's priority in this scenario. The child's head injury could potentially be serious, but priority should be given to neurological assessments and signs of increased intracranial pressure.
Choice B rationale:
Nasal discharge negative for glucose is not indicative of a major issue in this context. While cerebrospinal fluid (CSF) leaking from the nose after head trauma is a concern, it is not mentioned in this scenario, and this choice does not take precedence over other neurological signs.
Choice C rationale:
This is the correct answer. Asymmetric pupils can be a sign of a serious neurological issue, such as a brain injury or increased intracranial pressure. It requires immediate attention and further evaluation to assess the child's neurological status and determine the extent of the injury.
Choice D rationale:
A negative Babinski reflex is a normal finding in this context and does not require immediate priority attention. The Babinski reflex is typically present in infants and disappears as the child grows older. Its absence is expected in older children and adults.
