A nurse is admitting a child who has pertussis. Which of the following transmission-based precautions should the nurse initiate?

Choice A reason: While exposure to secondhand smoke is unhealthy and should be avoided, it is not commonly listed as a trigger for seizures. The primary concern with secondhand smoke is its impact on respiratory health.

Choice Breason: A prolonged headache can be a symptom of various conditions, but it is not generally considered a direct trigger for seizures. However, if a headache is related to a neurological condition, it may be associated with an increased risk of seizures.

Choice Creason: Decreased temperature, or being cold, is not typically a trigger for seizures. Seizure triggers are usually related to changes in the body's internal environment or external stimuli that affect the nervous system.

Choice D reason: Inadequate sleep is a well-known trigger for seizures. Sleep deprivation can lead to increased seizure activity in individuals with seizure disorders. Ensuring adequate and regular sleep is an important part of managing seizure disorders.

Choice A reason: Weight loss is not typically an indication of heart failure. In fact, patients with heart failure may experience weight gain due to fluid retention.

Choice B reason: Decreased respirations are not a common sign of heart failure. Instead, heart failure can cause increased respiratory rate and effort due to fluid accumulation in the lungs.

Choice C reason: Exercise intolerance, or difficulty in engaging in physical activity, is a classic symptom of heart failure. It occurs due to the heart's inability to pump enough blood to meet the body's demands during exercise.

Choice D reason: Bradycardia, or a slower than normal heart rate, is not a direct indication of heart failure. While it can be associated with certain cardiac conditions, it is not a specific sign of heart failure.
