A nurse is caring for a child who has an exacerbation of cystic fibrosis. Which of the following laboratory findings should the nurse report to the provider immediately?
Blood glucose 140 mg/dL
Serum sodium 156 mEq/L
RBC 3.2 million/ul
Oxygen saturation 85%
The Correct Answer is D
D. An oxygen saturation level of 85% is significantly below the normal range and indicates hypoxemia (low blood oxygen levels). This finding is concerning, especially in a child with cystic fibrosis, which can lead to respiratory complications such as airway obstruction, infection, or mucus plugging.
A. A blood glucose level of 140 mg/dL is within the normal range for children, so this finding would not typically require immediate reporting to the provider.
B. A serum sodium level of 156 mEq/L is significantly elevated and above the normal range. However, hypoxia is the priority.
C. A red blood cell (RBC) count of 3.2 million/µL falls within the normal range for children, so this finding would not typically require immediate reporting to the provider.

Correct Answer is A
Explanation
A. Exposure to environmental tobacco smoke (passive smoking) is a known risk factor for otitis media, as it can irritate the upper respiratory tract and increase susceptibility to respiratory infections, including those affecting the ears.
B. Excessive earwax buildup can sometimes contribute to ear discomfort or hearing problems but it is not a common cause of persistent otitis media. However, it's still important for the nurse to assess for any earwax issues as part of the overall assessment of the child's ear health.
C. Drinking water is generally beneficial for overall health but is not directly linked to otitis media unless there are specific concerns about hydration status or exposure to contaminated water sources.
D. Water entering the ears during bathing is not generally considered a significant risk factor for otitis media, but it can be associated with otitis externa, which is an infection of the outer ear canal.
Correct Answer is A
Explanation
A. Rheumatic fever often develops as a complication of untreated or inadequately treated streptococcal throat infections, particularly group A Streptococcus. A history of a recent sore throat in a family member could suggest a streptococcal infection, which is a risk factor for developing rheumatic fever.
B. Chickenpox is caused by the varicella-zoster virus and is not directly related to rheumatic fever. While viral infections can trigger or exacerbate rheumatic fever in susceptible individuals, chickenpox itself is not a significant risk factor for rheumatic fever.
C. Fifth disease, also known as erythema infectiosum, is caused by parvovirus B19 and is not associated with rheumatic fever. Fifth disease primarily affects the skin, causing a characteristic rash, and is typically a mild illness in children.
D. Gastritis, inflammation of the stomach lining, is not directly related to rheumatic fever. While some gastrointestinal conditions may be associated with autoimmune disorders, gastritis itself is not a known risk factor for rheumatic fever.
