A patient is admitted with an open fracture of the tibia after a bicycle accident. What information would the nurse obtain when assessing the patient?
The status of tetanus immunization.
Whether the injury was exposed to dirt or gravel.
Any previous injuries to the leg.
The use of antibiotics in the last month.
The Correct Answer is A
Choice A reason: Assessing tetanus immunization status is critical for an open fracture, as wounds exposed to soil or debris risk Clostridium tetani infection. Tetanus prophylaxis (vaccine or immunoglobulin) prevents lockjaw and neuromuscular complications. This ensures timely immunization, reducing life-threatening infection risks in contaminated wounds like those from bicycle accidents.
Choice B reason: Determining exposure to dirt or gravel is essential, as open fractures are prone to bacterial contamination (e.g., Staphylococcus aureus or Pseudomonas). Contaminated wounds require urgent irrigation, debridement, and antibiotics. This assessment guides infection prevention, ensuring prompt surgical and antimicrobial interventions to minimize osteomyelitis or sepsis risks in open tibial fractures.
Choice C reason: Previous leg injuries are relevant for overall musculoskeletal history but not immediate for open fracture management. Current wound contamination and infection risk take precedence. Focusing on past injuries delays critical interventions like tetanus prophylaxis or debridement, potentially worsening outcomes in acute open fractures from bicycle accidents.
Choice D reason: Recent antibiotic use is less urgent than contamination or tetanus status in open fractures. While it may inform antibiotic resistance, it’s not a primary assessment focus. Prioritizing this risks delaying wound cleaning and prophylaxis, increasing infection risks like cellulitis or osteomyelitis in contaminated open tibial fractures.

Correct Answer is B
Explanation
priority. Protein aids long-term recovery by promoting bone healing, but infection control is critical to prevent systemic spread or bone necrosis. Nutritional support is secondary to addressing the acute bacterial infection driving the condition.
Choice B reason: Administering antibiotics is the priority in acute osteomyelitis, a bacterial bone infection (often Staphylococcus aureus). Prompt antibiotics target the infection, preventing sepsis, abscess formation, or chronic osteomyelitis. Delaying treatment risks bone destruction and systemic complications, making timely antibiotic administration essential to control the infection and preserve bone integrity.
Choice C reason: Teaching relaxation breathing reduces pain perception by calming the nervous system but does not address the underlying infection in osteomyelitis. Pain management is important but secondary to antibiotics, which target the bacterial cause. Without infection control, pain will persist, and complications like bone damage may worsen.
Choice D reason: Providing antipyretic therapy manages fever, a symptom of osteomyelitis, but does not treat the infection itself. Fever reflects the body’s immune response to bacteria, and while comfort is important, antibiotics are the priority to eradicate the pathogen, preventing progression to sepsis or chronic bone infection.
Correct Answer is D
Explanation
Choice A reason: Probenecid increases uric acid excretion by inhibiting renal reabsorption, used for chronic gout prevention, not acute attacks. It is ineffective for rapid symptom relief, as it does not address inflammation or pain directly. During an acute attack, uricosurics may even worsen symptoms by mobilizing uric acid, making this inappropriate.
Choice B reason: Ibuprofen, an NSAID, reduces inflammation and pain in acute gout but is not specific to gout’s pathophysiology. It provides symptomatic relief but does not target uric acid crystal-induced inflammation as effectively as colchicine. It is often used adjunctively, not as the primary treatment for an acute gout attack.
Choice C reason: Hydrocortisone, a corticosteroid, may be used for gout when NSAIDs or colchicine are contraindicated, reducing inflammation. However, it is not the first-line choice due to systemic side effects like immunosuppression. Colchicine is preferred for its specificity in targeting neutrophil-mediated inflammation in acute gouty arthritis.
Choice D reason: Colchicine is the primary medication for acute gout, inhibiting microtubule polymerization and neutrophil migration, reducing uric acid crystal-induced inflammation. Administered early, it relieves pain and swelling effectively. Its specificity for gout’s pathophysiology makes it the anticipated choice for both preventing and treating acute attacks, minimizing joint damage.
