A 10-year-old sustained a spider bite on his ankle a week ago and now presents with redness, swelling, and tenderness. He denies any other fall or injury. X-ray of the ankle is unremarkable. CBC shows elevated WBC. What is the most likely diagnosis for this child?
Compartment syndrome
Osteomyelitis
Osteogenesis imperfecta
Juvenile idiopathic arthritis
The Correct Answer is B
Choice A reason:
Compartment syndrome is a condition where increased pressure within a muscle compartment leads to decreased blood flow, which can cause muscle and nerve damage. It is typically associated with severe trauma, fractures, or crush injuries. The symptoms include severe pain, swelling, and decreased sensation or movement in the affected limb. In this case, the child’s symptoms of redness, swelling, and tenderness following a spider bite, along with an elevated WBC, are more indicative of an infection rather than compartment syndrome.
Choice B Reason:
Osteomyelitis is an infection of the bone, which can occur following an injury or infection elsewhere in the body. The symptoms include redness, swelling, tenderness, and pain in the affected area, along with fever and elevated WBC. Given the child’s history of a spider bite and the presence of redness, swelling, tenderness, and elevated WBC, osteomyelitis is the most likely diagnosis. The unremarkable X-ray does not rule out osteomyelitis, as early stages of the infection may not show changes on X-ray.
Choice C Reason:
Osteogenesis imperfecta, also known as brittle bone disease, is a genetic disorder characterized by fragile bones that break easily. It is not associated with infections or elevated WBC. The symptoms of osteogenesis imperfecta include frequent fractures, blue sclerae, and hearing loss. The child’s symptoms of redness, swelling, and tenderness following a spider bite, along with an elevated WBC, are not consistent with osteogenesis imperfecta.
Choice D Reason:
Juvenile idiopathic arthritis (JIA) is a type of arthritis that occurs in children. It is characterized by persistent joint inflammation, pain, and swelling. While JIA can cause joint tenderness and swelling, it is not typically associated with a recent injury or infection, such as a spider bite. Additionally, JIA does not usually cause elevated WBC. The child’s symptoms are more indicative of an infection, making osteomyelitis the more likely diagnosis.

Correct Answer is D
Explanation
The correct answer is d) Recurrent kidney infections.
Choice A reason:
Infarction of the renal vessels is not a common consequence of vesicoureteral reflux (VUR). Infarction refers to tissue death due to a lack of blood supply, which is not typically associated with VUR1. VUR primarily affects the urinary tract, leading to the backward flow of urine from the bladder into the ureters and kidneys. This condition can cause other complications, but infarction of the renal vessels is not one of them.
Choice B reason:
Renal calculi, or kidney stones, are not directly caused by vesicoureteral reflux. While VUR can lead to urinary tract infections (UTIs), which may increase the risk of developing kidney stones, it is not the primary outcome. Kidney stones are typically formed due to an imbalance of minerals and salts in the urine, leading to crystallization. VUR itself does not directly cause the formation of renal calculi.
Choice C reason:
Urinary obstruction is not a typical result of vesicoureteral reflux. VUR involves the backward flow of urine, but it does not usually cause a physical blockage in the urinary tract. Urinary obstruction can occur due to other conditions, such as congenital abnormalities, tumors, or kidney stones, but it is not a direct consequence of VUR.
Choice D reason:
Recurrent kidney infections are a common complication of vesicoureteral reflux. The backward flow of urine can carry bacteria from the bladder into the kidneys, leading to repeated episodes of pyelonephritis (kidney infection). These recurrent infections can cause kidney damage over time if not properly managed. Therefore, it is crucial to monitor and treat VUR to prevent recurrent kidney infections and preserve kidney function.
Correct Answer is C
Explanation
Choice A: Apply antibiotic ointment to pin sites daily
Applying antibiotic ointment to pin sites daily is not relevant in the context of Buck extension traction. Buck’s traction is a type of skin traction, which does not involve pins or pin sites. Pin site care is typically associated with skeletal traction, where pins are inserted directly into the bone.
Choice B: Remove the traction boot during baths
Removing the traction boot during baths is not recommended. The traction boot should remain in place to maintain the alignment and immobilization of the affected limb. Removing the boot can disrupt the traction and potentially worsen the condition.
Choice C: Assess neurovascular status every 2 hours
Assessing neurovascular status every 2 hours is crucial for a child in Buck extension traction. This involves checking the circulation, sensation, and movement of the affected limb to ensure there are no complications such as nerve damage or impaired blood flow. Regular neurovascular assessments help in early detection and prevention of complications.
Choice D: Reduce fluid intake
Reducing fluid intake is not a standard care practice for a child in Buck extension traction. Adequate hydration is important for overall health and recovery. There is no indication that fluid intake should be restricted in this scenario.
