A patient with a humeral fracture is returning for a 4-week checkup. The nurse explains that initial evidence of healing on x-ray is indicated by

Choice A reason: Applying pediculicide lotion is inappropriate for tick removal, as it targets lice, not ticks. This could irritate the skin or prompt the tick to regurgitate, increasing the risk of pathogen transmission, such as Borrelia burgdorferi causing Lyme disease. Proper removal uses mechanical extraction to minimize infection, ensuring safe and effective tick removal without chemical interference.

Choice B reason: Using a hot ember to remove a tick is hazardous and ineffective. Heat may cause the tick to release pathogens into the bite site, heightening infection risk, and can burn the skin. Safe removal involves tweezers grasping the tick near the skin for intact extraction, reducing complications like Lyme disease or Rocky Mountain spotted fever transmission.

Choice C reason: Grasping the tick close to the skin with fine-tipped tweezers is the standard method. This ensures complete removal, including mouthparts, minimizing infection risk from pathogens like Borrelia burgdorferi, which causes Lyme disease. The technique prevents tissue damage and pathogen spread, promoting safe extraction and reducing complications from tick-borne illnesses.

Choice D reason: Using a twisting motion risks breaking the tick’s mouthparts, leaving them embedded, which increases infection risk and complicates removal. A steady, upward pull without twisting is recommended to extract the tick fully, preventing transmission of diseases like Lyme disease or babesiosis, ensuring effective and safe tick removal.

Choice A reason: Localized erythema is a key manifestation of acute osteomyelitis, reflecting bacterial infection (often Staphylococcus aureus) in bone tissue following a puncture wound. Inflammation causes vasodilation and immune cell infiltration, producing redness, warmth, and swelling. Recognizing this prompts urgent antibiotic therapy and possible surgical debridement to prevent bone destruction and systemic infection.

Choice B reason: Hypothermia is not typical of acute osteomyelitis, which often presents with fever due to systemic inflammatory response to bone infection. Hypothermia may occur in sepsis or unrelated conditions but isn’t a hallmark. Expecting hypothermia misguides assessment, potentially delaying critical interventions like antibiotics for osteomyelitis’s infectious process.

Choice C reason: Bradycardia is not associated with acute osteomyelitis, which may cause tachycardia from fever and inflammation. Bradycardia suggests cardiac or autonomic issues, not bone infection. Assuming bradycardia misdirects focus from osteomyelitis’s infectious signs like erythema, risking delayed treatment and progression to chronic infection or abscess formation.

Choice D reason: Numbness of toes suggests nerve compression or vascular compromise, not acute osteomyelitis. Osteomyelitis causes localized pain, erythema, and swelling from bone infection, not sensory loss. Expecting numbness misdiagnoses the condition, potentially overlooking infection and delaying antibiotics or surgical intervention critical for preventing bone necrosis and systemic spread.
