**Question:** One of the following is false regarding complications of protein energy malnutrition:

A. Kwashiorkor
B. Marasmus
C. Delayed wound healing
D. Increased risk of infections

**Core Concept:**
Protein Energy Malnutrition (PEM) is a severe deficiency in dietary protein and energy leading to impaired growth, development, and functioning of the body. It is classified into two main types: Kwashiorkor and Marasmus, both with their unique clinical features. Delayed wound healing is a common complication associated with PEM, while increased infections are a result of the weakened immune system due to malnutrition.

**Why the Correct Answer is Right:**
Marasmus is a severe malnutrition characterized by wasting, emaciation, and low body fat, while Kwashiorkor is a form of PEM characterized by edema, oedema, and elevated body fat. Both types of PEM lead to impaired wound healing due to the deficiency of essential nutrients, particularly proteins and energy, which are crucial for tissue repair and regeneration.

**Why Each Wrong Option is Incorrect:**
Option A (Kwashiorkor) and Option B (Marasmus) are both types of severe malnutrition and are thus relevant complications of PEM. However, "Delayed wound healing" is not a complication of Kwashiorkor, as it is associated with Marasmus.

**Clinical Pearl:**
In cases of severe malnutrition, clinicians should be aware of the increased risk of infections and impaired wound healing due to weakened immune system and tissue repair capabilities, respectively. This knowledge can help guide appropriate management strategies and timely interventions for patients with PEM.
