Many fractures are caused by traumatic injuries, but some fractures are caused by disease processes.
True.
False.
The Correct Answer is A
Choice A rationale
Fractures caused by disease processes are termed pathological fractures. Diseases like osteoporosis weaken bones, increasing susceptibility to fractures. Conditions like cancer can invade bone tissue, causing structural fragility. Pathological fractures occur without significant trauma, distinguishing them from those caused by external injuries, which require high-impact forces to break otherwise healthy bones. By definition, trauma fractures arise from external forces, while pathological ones involve internal conditions compromising bone integrity.
Choice B rationale
Traumatic fractures stem from external forces, not from disease processes. This assertion neglects the reality of pathological fractures, which result from diseases undermining the bone's natural strength. Healthy bones typically endure significant stress before fracturing, and the absence of disease makes fractures from minimal trauma highly unlikely. This reasoning excludes pathological fractures caused by internal illnesses or conditions weakening bone structures.

Correct Answer is A
Explanation
Choice A rationale
Twelve hours without voiding indicates potential acute urinary retention due to ureteral obstruction, risking hydronephrosis or kidney damage, which requires immediate attention to preserve renal function.
Choice B rationale
Hematuria is common with kidney stones and generally not urgent unless accompanied by clots causing retention or excessive bleeding causing hemodynamic instability.
Choice C rationale
Fever indicates infection but at 37.7°C, it is considered low-grade and less urgent compared to obstruction. Normal body temperature is typically 36.1-37.2°C.
Choice D rationale
Cloudy urine suggests infection but lacks the immediacy of urinary retention or acute obstruction, which are potentially life-threatening.
Correct Answer is C
Explanation
Choice A rationale
Applying a warm pack is inappropriate for controlling active bleeding, as it can exacerbate blood flow to the site, worsening the hemorrhage rather than controlling it effectively.
Choice B rationale
Using a tourniquet above the bleeding site is a last-resort method typically reserved for life-threatening bleeding. It may cause complications such as nerve damage or ischemia, so other measures are prioritized first.
Choice C rationale
Direct pressure or sterile pressure dressing with elevation minimizes blood loss effectively by compressing the damaged vessels, promoting clot formation, and utilizing gravity to reduce the pressure at the wound site. It is the recommended first-line method.
Choice D rationale
Placing an ice pack on the bleeding site may reduce localized blood flow by inducing vasoconstriction but is less effective than direct pressure for stopping active hemorrhage. It is secondary to other control measures.
