Protein energy malnutrition leads to?

Appeared in: IGNOU Post B. SC. Nursing entrance-2019

Explanation

Kwashiorkor is a severe form of protein-energy malnutrition (PEM), which is a spectrum of conditions caused by inadequate intake of protein and/or energy.
It is specifically caused by a diet that is deficient in protein, even if the calorie intake is sufficient.
The hallmark signs of Kwashiorkor include bilateral pitting edema (swelling), hypoalbuminemia, fatty liver, and characteristic skin lesions often described as 'flaky paint' dermatitis.

Option B: Pellagra is caused by a deficiency of niacin (vitamin B3), not a general protein-energy deficit.
Option C: Rickets is a condition of bone softening in children caused by a deficiency or impaired metabolism of vitamin D, phosphorus, or calcium.
Option D: Gum bleeding is a classic symptom of scurvy, which results from a severe deficiency of vitamin C (ascorbic acid).

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Nutritional Deficiency Disorders as background academic context rather than a clinical decision trigger.
Nurses are pivotal in identifying PEM through nutritional assessments, including measuring Mid-Upper Arm Circumference (MUAC) and checking for bilateral pitting edema, especially in vulnerable populations like children and the elderly.
Early detection and initiation of a structured refeeding program are critical to prevent irreversible physical and cognitive damage and to reduce mortality.
What if? If the question described a child with severe wasting, loss of muscle and fat, and a 'skin and bones' appearance but no edema, the correct answer would be Marasmus, the other major form of severe PEM.

How to Approach the Question

This is a factual recall question that tests your knowledge of major nutritional disorders.
First, identify the core concept in the stem: 'Protein energy malnutrition' (PEM).
Recall the two primary clinical syndromes resulting from severe PEM: Kwashiorkor (protein-deficient) and Marasmus (energy and protein deficient).
Scan the options provided. 'Kwashiorkor' is listed as an option.
To confirm, quickly evaluate the other options. Pellagra (B3), Rickets (Vit D), and Gum bleeding/Scurvy (Vit C) are all caused by specific vitamin deficiencies, not a general protein-energy deficit.
Therefore, Kwashiorkor is the most direct and correct answer for a condition resulting from PEM.
