A nurse is calculating a client's body mass index (BMI). Which of the following information does the nurse require?

A. Glucose is a simple sugar and is readily broken down and absorbed by the body for energy.
B. Fiber, a type of carbohydrate, cannot be digested by human digestive enzymes. It passes through the digestive system intact, aiding in bowel movements and promoting gut health.
C. Glycerol is a component of triglycerides (fats) and can be metabolized by the body for energy.
D. Fatty acids are the building blocks of fats and are broken down by digestive enzymes for absorption.

A. Lactose intolerance is more related to the absence of the enzyme lactase, commonly found in individuals who have a reduced ability to digest lactose (milk sugar), regardless of their dietary choices.
B. Vegan diets may lack sufficient iron intake as plant-based sources of iron (non-heme iron) are not as readily absorbed by the body compared to heme iron found in animal products. This can put vegans at a higher risk of iron deficiency.
C. Diabetes risk is influenced by various factors, including genetics and lifestyle, rather than specifically by following a vegan diet.
D. Pneumonia risk is not directly associated with following a vegan diet but can be influenced by overall health, immune function, and exposure to pathogens.
