Insulin glargine (Lantus) is what type of insulin?
Long-acting insulin.
Rapid-acting insulin.
Intermediate-acting insulin.
Short-acting insulin.
The Correct Answer is A
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.

Correct Answer is ["A","B","D"]
Explanation
Choice A rationale
Keeping the patient NPO minimizes gastrointestinal motility and prevents further accumulation of intestinal contents, reducing the risk of perforation and worsening obstruction. Bowel rest is crucial in promoting resolution.
Choice B rationale
Nasogastric tube placement alleviates distention by decompressing the stomach and removing gastric contents, reducing vomiting and the risk of aspiration while improving patient comfort.
Choice C rationale
Rectal tubes are not effective in decompressing small bowel obstructions since the obstruction prevents material from reaching the rectum.
Choice D rationale
Frequent oral care prevents mucosal dryness and infection risk in patients who are NPO and receiving suction therapy, promoting overall oral hygiene.
Correct Answer is A
Explanation
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.
