A. The body cell mass compartment reflects the body's:

1. Muscle and organ tissues
2. Stored fat and lean body mass tissues
3. Carbon dioxide producing, glucose burning tissues
4. The compartment where most anabolic and catabolic metabolic processes occur
5. 1, 3 and 4

B. Extracellular mass (or extracellular tissue) reflects the body's:

1. Fat storage
2. Bone and collagen tissues
3. Extracellular fluids
4. Transport fluids for plasma proteins, gases, lipids and carbohydrates
5. 2, 3 and 4

C. Most of the weight lost during simple starvation is from the:

1. Body cell mass compartment
2. Extracellular mass compartment
3. Fat compartment
4. Lean body mass compartment
5. None of the above

D. When weight is lost from exercise:

1. More fat is lost than in starvation
2. More lean tissue is typically lost
3. Is due to the loss of potassium in the cells
4. It is less effective than dieting at producing the maximum weight loss
5. 1 and 4

E. The gold stand used to validate other methods for estimating fat volume is:

1. Total body potassium counting
2. Dual energy x-ray absorptiometry
3. Hydrodensitometry
4. Anthropometry
5. Bioelectrical Impedance Analysis

F. Fat-free mass reflects which of the following combinations of tissues:

1. Body cell mass and essential fat mass
2. Stored fat tissues and extracellular tissues
3. Bone, collagen and total body water
4. Body cell mass and extracellular tissues
5. Extracellular mass and essential fat tissues

G. The limitations to the accurate estimates of body compartments by bioelectrical impedance analysis include:

1. Error in recorded height
2. Misplacement of electrodes
3. Patient lying flat on a non-conducting surface
4. All of the above
5. 1 and 2

H. Optimal and appropriate body cell mass should be calculated based on:

1. Current body weight
2. Muscularity
3. Height
4. Ideal body weight
5. 3 and 4

I. Frame size can change the estimate of body cell mass:

1. +/- fat mass
2. +/- 10%
3. +/- 2 kg
4. +/- extracellular tissue
5. +/- 20%

J. Estimates for appropriate levels of extracellular tissue are based on:

1. Ideal body weight
2. Desired body weight
3. Frame size and sex
4. Current body weight and sex
5. Change in body weight and frame size

K. Estimates for appropriate levels of fat tissue are based upon:

1. Ideal body weight
2. desired body weight
3. Frame size and sex
4. Current body weight and frame size
5. Change in body weight and frame size

L. Which of the following may be reasons for a decrease in body cell mass?:

1. Starvation
2. Stress (infection or injury)
3. Metabolic alteration (altered hormonal balance)
4. Increased food intake
5. a, b and c

M. Which of the following may be reasons for an increase in body cell mass?:

1. re-feeding and overfeeding
2. Recovery from stress
3. Anabolic therapy
4. Exercise
5. 1, 2, 3 and 4

N. Variations in body weight of more than 0.5 kg:

1. Is a normal variation
2. depends on if you have emptied your bladder before weighing in
3. Suggests an imbalance of energy or water or both
4. Is a result of uncomplicated semi-starvation
5. Stops occurring after the second day of dieting

O. The raw data used to estimate body compartments using bioelectrical impedance analysis include:

1. Resistance, age, sex and most recent meal
2. Reactance, exercise, age and sex
3. Resistance, reactance, height, weight and sex
4. Age, resistance, reactance, height and weight
5. Anthropometry, resistance, reactance and weight
