What is the most common cause of a urinary tract infection?

Choice A reason: Sweating, trembling, and confusion indicate hypoglycemia in type 1 diabetes, likely from excess insulin. Administering fast-acting carbohydrates (e.g., glucose tablets, juice) rapidly raises blood glucose by providing readily absorbable sugars, reversing neuroglycopenic symptoms. This is the first action to prevent seizures or coma, ensuring immediate stabilization.

Choice B reason: Administering insulin during hypoglycemia would further lower blood glucose, exacerbating symptoms and risking severe outcomes like unconsciousness. Insulin drives glucose into cells, worsening the deficit. This action is contraindicated and dangerous, as it directly opposes the need to raise blood sugar immediately.

Choice C reason: Complex carbohydrates and proteins digest slowly, providing delayed glucose release, unsuitable for acute hypoglycemia requiring rapid correction. While appropriate for long-term glucose stability, this is not the first action, as it fails to address the urgent need for fast-acting sugars to reverse symptoms.

Choice D reason: Calling the healthcare provider delays treatment of hypoglycemia, which requires immediate carbohydrate administration to prevent neurological damage. While provider consultation may follow for insulin adjustment, it is not the first action. This choice is inappropriate, as it postpones critical intervention needed for symptom resolution.

Choice A reason: Ecchymosis, or bruising, may occur with a fracture due to soft tissue injury and bleeding but is not specific to fractures. It results from ruptured blood vessels in the skin, not bone disruption, and can occur in many trauma scenarios, making it less definitive than crepitus for fracture assessment.

Choice B reason: Crepitus, the grating sound or sensation from bone fragments rubbing together, is a hallmark of fractures. It occurs due to disrupted bone continuity, detectable during physical examination. This clinical manifestation is highly specific to fractures, making it the most accurate choice for a nurse’s assessment focus.

Choice C reason: Shock can occur with severe fractures due to blood loss or pain but is not a direct manifestation of the fracture itself. It reflects systemic response to trauma, not the localized bone injury, making it less specific than crepitus for identifying a fracture during assessment.

Choice D reason: Deformity is a common fracture sign due to bone misalignment but is not always present, especially in hairline or non-displaced fractures. Crepitus is more consistently detectable in physical exams, as it directly results from bone fragment movement, making it a more reliable clinical manifestation.
