A nurse is reviewing the laboratory report of a newly admitted school-age child who has a fever. The nurse should identify which of the following laboratory results is an indication of an infection and should be reported to the charge nurse immediately.
Urine osmolality 500 mOsm/kg.
WBC 17,500/mm3.
BUN 12 mg/dL.
Urine specific gravity 1.014.
The Correct Answer is B
Choice A rationale:
Urine osmolality 500 mOsm/kg. Urine osmolality is a measure of urine concentration and is not a reliable indicator of infection. It reflects the kidney's ability to concentrate urine and can vary based on hydration status and other factors. An elevated urine osmolality could suggest dehydration, not necessarily infection.
Choice B rationale:
WBC 17,500/mm3. This is the correct choice. An elevated white blood cell count (WBC) is a hallmark sign of infection. The body's immune response to an infection often includes an increase in WBC count, particularly the neutrophil count. This elevation is known as leukocytosis and is a red flag for infection.
Choice C rationale:
BUN 12 mg/dL. Blood Urea Nitrogen (BUN) measures kidney function and hydration status. While an elevated BUN can indicate dehydration, it is not a specific marker for infection. BUN levels can be influenced by various factors, including diet and renal function.
Choice D rationale:
Urine specific gravity 1.014. Urine-specific gravity reflects the concentration of solutes in urine and the kidney's ability to concentrate or dilute urine. While changes in urine specific gravity can indicate dehydration or overhydration, it is not a direct indicator of infection. An infection is better detected through changes in WBC count and other clinical signs.

Correct Answer is B
Explanation
Choice A rationale:
Avoiding discussions about the child's diagnosis with the sibling might create confusion and anxiety for the sibling. Open communication is essential for helping siblings understand their brother or sister's condition and cope with the changes in the family dynamic.
Choice B rationale:
Encouraging phone calls between the siblings is a positive step in promoting sibling adaptation when one of them has a chronic illness like cystic fibrosis. Maintaining connections through communication helps siblings feel involved, valued, and informed about each other's lives and challenges.
Choice C rationale:
Designating one parent to stay at home with the sibling might lead to feelings of isolation and neglect for the child with cystic fibrosis. Siblings also need support and attention during this time, and isolating one parent could hinder healthy sibling relationships.
Choice D rationale:
Avoiding having the sibling visit the child in the facility may prevent the sibling from understanding the condition and create a sense of fear or confusion. Controlled, supervised visits can actually be beneficial, as they allow the siblings to interact and support each other in a safe environment.
Correct Answer is ["B","D"]
Explanation
Choice A rationale:
Allowing an adolescent driver to answer their phone while driving can lead to distraction, increasing the risk of accidents. Engaging in conversations on the phone diverts the driver's attention from the road, which is unsafe. It's crucial for drivers, especially new ones, to focus solely on driving to prevent accidents.
Choice B rationale:
This choice is correct. Not answering the phone while driving is a responsible behavior that indicates an understanding of the dangers of distracted driving. Parents should encourage their children to focus on the road and avoid distractions like phone calls, promoting safe driving practices.
Choice C rationale:
This statement is incorrect. Adolescents should continue wearing helmets when riding their bikes even after age 13. Wearing helmets helps prevent head injuries in case of accidents. While older adolescents might perceive themselves as less prone to accidents, they are still at risk, and helmets are essential for their safety.
Choice D rationale:
This choice is correct. Wearing appropriate protective clothing, like long pants, while driving an all-terrain vehicle (ATV) is crucial. Long pants can provide some degree of protection against scrapes, scratches, and minor injuries that can occur while operating an ATV. It's a safety measure that shows an understanding of the importance of protective gear.
