A child hospitalized for treatment of osteomyelitis complains that he is tired of being sick and wants to know when the antibiotic protocol will end. How long will the nurse indicate that antibiotic therapy will probably last?
2 weeks.
6 weeks.
2 months.
3 months.
The Correct Answer is B
Choice A reason: Two weeks of antibiotics is insufficient for osteomyelitis, a bone infection requiring prolonged therapy to penetrate bone tissue and eradicate bacteria (e.g., Staphylococcus aureus). Short courses risk recurrence or chronic infection, as bone has poor vascularity, slowing antibiotic delivery.
Choice B reason: Osteomyelitis in children typically requires 4–6 weeks of antibiotics to ensure complete bacterial eradication from bone tissue, which has limited blood supply. This duration allows adequate penetration to prevent relapse or complications like abscesses, making it the standard treatment length.
Choice C reason: Two months (8 weeks) exceeds the typical 4–6 week course for uncomplicated pediatric osteomyelitis. Prolonged therapy may be needed for chronic cases or complications, but 6 weeks is sufficient for most acute cases, avoiding unnecessary antibiotic exposure.
Choice D reason: Three months is excessive for most cases of acute osteomyelitis in children. Such extended therapy is reserved for chronic osteomyelitis or resistant organisms, increasing risks of antibiotic resistance or side effects like renal toxicity without added benefit.

Correct Answer is B
Explanation
Choice A reason: Guiding a child to the floor during a seizure is unsafe, as it risks injury to both the child and nurse due to uncontrolled movements. Leaving to get help abandons the child, increasing injury risk during the seizure’s tonic-clonic phase.
Choice B reason: Moving objects away from a child during a tonic-clonic seizure prevents injury from striking hard surfaces. Generalized seizures cause uncontrolled muscle contractions, increasing the risk of trauma. Ensuring a safe environment is a priority to minimize harm during the seizure event.
Choice C reason: Inserting a tongue blade, even padded, risks dental injury or airway obstruction, as jaw clenching is common in tonic-clonic seizures. Current guidelines advise against placing objects in the mouth, as it does not prevent tongue biting and may cause harm.
Choice D reason: Restraining a child during a seizure can cause fractures or soft tissue injury due to forceful muscle contractions. It also increases stress and hypoxia risk. Allowing the seizure to occur while ensuring safety is the recommended approach to minimize complications.
Correct Answer is C
Explanation
Choice A reason: Stress fractures result from repetitive microtrauma, common in athletes, not typically associated with abuse. In children, they occur from overuse (e.g., sports), not acute trauma, making them less suspicious for non-accidental injury compared to other fracture types.
Choice B reason: Compound fractures, where bone pierces the skin, result from high-impact trauma (e.g., falls). While possible in abuse, they are less specific, as they occur in accidents, making them less indicative of non-accidental injury than spiral fractures.
Choice C reason: Spiral fractures occur from twisting forces, often seen in abuse when a limb is forcefully twisted (e.g., by an adult). In children, whose bones are flexible, spiral fractures suggest significant force, raising suspicion of non-accidental trauma.
Choice D reason: Greenstick fractures, where the bone bends and partially breaks, are common in children due to pliable bones. They occur in accidents or minor trauma, making them less specific to abuse compared to spiral fractures’ association with twisting mechanisms.
