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 C
Explanation
Choice A rationale
Incisions into the renal pelvis for stone removal describe open surgical methods, not ultrasonic lithotripsy. This invasive approach is reserved for cases where less invasive techniques fail or stones are inaccessible through standard methods. Lithotripsy avoids direct incisions, utilizing external energy for stone fragmentation.
Choice B rationale
Kidney incisions for stone removal align with nephrolithotomy procedures rather than ultrasonic lithotripsy. This alternative represents open surgical intervention, distinct from non-invasive lithotripsy technologies. Lithotripsy eliminates stones using sound waves or lasers, reducing surgical risks and recovery times.
Choice C rationale
Ultrasonic lithotripsy employs high-frequency sound waves to break stones into small fragments. This minimally invasive method allows natural passage through the urinary tract or facilitates removal via catheterization. It reduces complications compared to invasive surgeries and is highly effective for calculi management.
Choice D rationale
Laser fragmentation techniques differ from ultrasonic lithotripsy, involving concentrated light energy to break stones. While both are minimally invasive, ultrasonic methods utilize sound waves rather than light energy for disintegration. This technical distinction outlines lithotripsy's use of external sound waves for stone management.
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.
