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 B
Explanation
Choice A rationale
Moving the legs independently before turning can strain the spine and disrupt the surgical site. It does not ensure spinal alignment, which is critical after a laminectomy and discectomy to promote healing and prevent complications.
Choice B rationale
Placing a pillow between the legs and turning the body as a unit maintains spinal alignment, reducing stress on the surgical site. This technique, known as logrolling, ensures the spine remains stable during movement.
Choice C rationale
Turning the head and shoulders first, followed by the hips, legs, and feet, can result in twisting of the spine, which could compromise the surgical site and delay healing. It is not recommended.
Choice D rationale
Using side rails for movement requires significant upper body strength and may cause twisting of the spine, which is contraindicated post-spinal surgery. This method poses a risk of disrupting the surgical repair.
Correct Answer is A
Explanation
Choice A rationale
Insulin glargine (Lantus) is a long-acting insulin used for basal glycemic control in diabetic patients. It has a slow onset and a steady release over approximately 24 hours, mimicking natural insulin secretion to stabilize blood glucose levels and prevent fluctuations.
Choice B rationale
Rapid-acting insulins, such as insulin lispro or aspart, have fast onsets and short durations to manage postprandial glucose spikes. Insulin glargine does not have these properties, as it is used for long-term basal control rather than immediate blood sugar regulation.
Choice C rationale
Intermediate-acting insulins like NPH have a shorter duration and peak effect compared to long-acting insulins. Insulin glargine provides a consistent effect over 24 hours, distinguishing it from intermediate-acting options.
Choice D rationale
Short-acting insulins are designed for pre-meal blood sugar control with a quick onset and limited duration. Insulin glargine does not fit this description due to its long-acting properties.
