Answer to Question 1

B
In a patient receiving fat-free parenteral nutrition, eczema may be a sign of essential fatty acid deficiency. Vitamin C deficiency is not affected by fat intake; symptoms include bleeding gums and breakdown of scar tissue. Eczema is not a sign of protein-energy malnutrition. The body makes phospholipids and sterol and so deficiency does not occur.

Answer to Question 2

2
Rationale: Phospholipids are present in cell walls and are comprised of phosphorous containing compounds. Cells that have a high content of ribonucleic acid (RNA) or nerve cells with a high myelin content have more phosphorous than other cells. Calcium, potassium, and magnesium are considered essential minerals and each play an important role in maintaining health.
