5.

What are the symptoms of bulimia nervosa?

6.

What are serious health risks of bulimia nervosa

A.

Electrolyte imbalance
B.

Inflammation of esophagus
C.

Tooth decay and staining
D.

Swollen salivary glands

Correct Answer(s)
A. Electrolyte imbalance
B. Inflammation of esopHagus
C. Tooth decay and staining
D. Swollen salivary glands

Explanation
Bulimia nervosa is an eating disorder characterized by binge eating followed by purging. Electrolyte imbalance occurs due to the frequent vomiting, which leads to abnormal levels of minerals in the body. Inflammation of the esophagus is a result of the stomach acid repeatedly coming into contact with the lining of the esophagus during vomiting. Tooth decay and staining are caused by the acid from the stomach eroding the tooth enamel. Swollen salivary glands occur due to the constant stimulation of saliva production during vomiting. These serious health risks highlight the damaging effects of bulimia nervosa on various body systems.

12.

What is body composition?

Correct Answer(s)
Fat Mass vs Lean Muscle Mass

Explanation
Body composition refers to the proportion of fat mass and lean muscle mass in the body. It is a measure of the amount of fat and muscle tissue present, which can vary from person to person. Fat mass refers to the amount of adipose tissue or body fat, while lean muscle mass refers to the amount of muscle tissue. Understanding body composition is important for assessing overall health and fitness levels, as it can help determine the risk of certain diseases and guide appropriate exercise and nutrition plans.

What are 5 methods used to measure body composition

A.

Skin Folds
B.

Bioelectrical impedance
C.

Underwater weighing
D.

DEXA(dual-energ x-ray absorptiometry
E.

Waist-hip ratio
F.

BMI

Correct Answer(s)
A. Skin Folds
B. Bioelectrical impedance
C. Underwater weighing
D. DEXA(dual-energ x-ray absorptiometry
E. Waist-hip ratio

Explanation
The answer is correct because skin folds, bioelectrical impedance, underwater weighing, DEXA (dual-energy x-ray absorptiometry), and waist-hip ratio are all commonly used methods to measure body composition. Skin folds involve measuring the thickness of skin folds at specific sites on the body. Bioelectrical impedance measures the resistance of electrical flow through the body to estimate body fat percentage. Underwater weighing measures body density by weighing a person underwater. DEXA uses x-ray technology to measure bone density and estimate body fat percentage. Waist-hip ratio compares the circumference of the waist to the circumference of the hips, which can indicate the distribution of body fat. BMI (body mass index) is not a direct measure of body composition, but it is commonly used to estimate body fatness based on height and weight.

How many kilocalories of excess energy = to one pound of gain

A.

2800
B.

4500
C.

3500
D.

1400

Correct Answer
C. 3500

Explanation
One pound of body weight gain is equivalent to 3500 kilocalories of excess energy. This means that in order to gain one pound of weight, a person needs to consume an excess of 3500 kilocalories more than what their body needs for daily activities and functions. This excess energy is stored as fat in the body, leading to weight gain.
