Which of the following is NOT a cause of stress related mucosal injury?
**Core Concept**
Stress-related mucosal injury refers to the damage of the gastric mucosa due to stress, leading to complications such as bleeding. The underlying principle involves the imbalance between mucosal protective factors and aggressive factors like acid and pepsin.
**Why the Correct Answer is Right**
Since the correct answer is not provided, let's discuss the general causes of stress-related mucosal injury, which include severe physiological stress, such as that caused by severe illness, trauma, or burns, leading to a reduction in mucosal blood flow and the release of inflammatory mediators.
**Why Each Wrong Option is Incorrect**
**Option A:** Would be incorrect if it listed a known cause of stress-related mucosal injury, such as severe physiological stress.
**Option B:** Similarly, would be incorrect if it mentioned another recognized cause.
**Option C:** Incorrect if it referred to a factor known to contribute to mucosal injury.
**Option D:** Might be the correct answer if it listed a factor not typically associated with stress-related mucosal injury.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that stress-related mucosal injury can be prevented with early enteral nutrition and the use of medications that reduce acid production, such as **H2 receptor antagonists** or **proton pump inhibitors**.
**Correct Answer:** D. Normal eating
