The nurse is caring for a 15 year old male in the Emergency Department. Please complete the diagram by specifying what condition the patient is likely experiencing, what actions to take, and what parameters to monitor.

Exhibits

Rationale for correct choices:

• Osteomyelitis: This is the most likely condition due to the patient’s fever, localized pain, warmth, erythema, and elevated white blood cell count. Osteomyelitis is an infection of the bone, often presenting with these classic signs, especially in children and adolescents.

• Obtain blood specimen for culture and sensitivity: It is essential to collect blood cultures before starting antibiotics to identify the causative organism. This allows for targeted antimicrobial therapy and improves treatment effectiveness.

• Administer Antibiotics: Prompt empiric antibiotic therapy is critical in suspected osteomyelitis to halt infection progression and prevent complications. Antibiotics should be started after blood cultures are drawn.

• Bone Necrosis: Osteomyelitis can lead to bone tissue death if untreated. Monitoring for signs of necrosis, such as worsening pain or loss of function, is vital to intervene timely and prevent permanent damage.

• Sepsis: Because osteomyelitis can progress to systemic infection, it is critical to monitor for sepsis signs, including high fever, tachycardia, hypotension, and altered mental status. Early detection improves patient outcomes.

Rationale for incorrect choices:

• Sickle Cell Disease: The absence of a prior medical history and typical sickle cell symptoms (such as vaso-occlusive crises or anemia) makes this diagnosis unlikely. The localized signs of infection like warmth, erythema, and fever suggest an infectious process rather than sickling-related pain.

• Compartment Syndrome: Usually follows trauma or injury and is characterized by intense pain, swelling, and decreased pulses. This patient has no trauma history and normal pulses, so compartment syndrome is unlikely here.

• Bone Fracture: Bone fractures typically result from acute trauma with immediate pain and swelling. The patient denies any recent injury, and symptoms have developed over several days, which is not characteristic of a fracture.

• Administer Benadryl: This antihistamine is used to treat allergic reactions and is not indicated in bone infections or fever. It would not address the underlying infection causing the patient’s symptoms.

• Administer Hydroxyurea: Hydroxyurea is used primarily in sickle cell disease to reduce crises and improve red blood cell function. It has no role in managing infections like osteomyelitis and would not benefit this patient.

• Prepare to remove cast: There is no cast present on this patient, so cast removal is not relevant. This action is unnecessary and does not address the current clinical picture.

• Pulmonary Embolism: Pulmonary embolism presents with sudden respiratory distress and chest pain, which are not part of this patient’s symptoms. Monitoring for this is not the priority in localized bone infection.

• Cast tightness: Since the patient does not have a cast, monitoring for tightness or complications related to a cast is not applicable in this scenario.

• Acute Chest Syndrome: This is a complication specific to sickle cell disease and does not apply to this patient, who lacks a history or symptoms consistent with that diagnosis.

Rationale:

A. Demonstrates cog-wheeling in arm movements and in walking and shows a characteristic shuffling gait when walking: Cog-wheeling and shuffling gait are more characteristic of Parkinson’s disease and are not associated with Duchenne muscular dystrophy or Gower’s sign.

B. Walks flat footed with a duck-like walk, although the child will not walk unless someone insists and makes the child walk: A waddling gait can occur in Duchenne muscular dystrophy, but reluctance to walk unless prompted is not a defining feature of Gower’s sign.

C. Uses a series of maneuvers and walks the hands up the legs in order to rise from a sitting to a standing position: This is the hallmark of Gower’s sign. It occurs due to proximal muscle weakness, especially in the hips and thighs, forcing the child to push on their own legs to stand.

D. Grabs onto furniture or people in order to get from any position to a standing position: While this suggests difficulty rising, reliance on external support does not describe Gower’s sign, which specifically involves using one’s own body for leverage.
