Answer All Questions Please!
1. What causes high-altitude cerebral edema (HACE)?
a. HACE occurs when a reduction in blood volume causes urine production to decrease.
b. HACE occurs when increased blood pressure causes fluid build up in the lungs.
c. HACE occurs when blood vessels in the brain constrict, causing fluid to leak out into the extracellular space.
d. HACE occurs when individuals experience headaches and shallow breathing after one hour at high altitude.
2. Mary has been at high altitude for seven hours and is experiencing nausea, rapid breathing, and headaches. What common issue is she likely experiencing?
a. HAPE
b. HACE
c. Dehydration
d. Acute mountain sickness
3. What are the four sets of effectors that help with thermoregulation of the body?
a. Skin arterioles, eccrine sweat glands, skeletal muscles, and endocrine glands.
b. Skin arterioles, eccrine sweat glands, left ventricle, and brain.
c. Eccrine sweat glands, left ventricle, hypothalamus, and skin.
d. Endocrine glands, sweat glands, blood vessels, and heart.
4. What exercise guidelines apply to pregnant women? Select all that apply.
a. Pregnant women who were sedentary before pregnancy, should not start exercising for the first time during pregnancy.
b. Pregnant women should perform repetitive exercise that target all major muscle groups (ex. walking or swimming).
c. During the first trimester, exercise can start at 15 minutes per day, 3 days per week, or as comfort and symptoms dictate.
d. Pregnant woman should focus on hydration and avoid exercising in hot environments.
e. Pregnant women should avoid strength training during pregnancy.
5. Ann is a healthy 65-year-old female who is interested in meeting physical activity guidelines for senior adults. Which of the following statements are true about those guidelines? Select all that apply.
a. Ann should only exercise for 2 hours or less per week.
b. Ann should strength train at least twice per week, focusing on all major muscle groups.
c. An should also focus on maintaining balance, flexibility, and agility.
d. Walking, cycling, and swimming are good options for starting out and accumulating exercise minutes.
e. Ann should complete at least 2.5 hours of moderate physical activity each week.
f. Ann should avoid strength training due to her older age.
6. Mark is out for a long run on a hot day. He is dehydrated and does not have water with him. As he tries to maintain a high exercise intensity, his body is likely experiencing the dual cardiovascular demand.
Which two factors make up this demand?
a. The need for additional blood plasma
b. The need to produce more sweat
c. The need for more ATP
d. The need for additional hydration
e. The need to pump additional blood to the surface of the skin
f. The need to pump additional blood to working muscles
7. True or false? Children and adolescents can improve bone health with regular physical activity, especially if they focus on high impact activities such as running and repeated jumping.
a. False
b. Children can only stimulate bone health by lifting weights in a gym setting.
c. True
8. How does non shivering thermogenesis contribute to thermoregulation?
a. It increases heat production by speeding up the rate of blood flow throughout the body.
b. It increases heat production by increasing metabolic activity.
c. It increases sweat production in hot environments
d. It vasoconstricts peripheral blood vessels and directs blood flow to the core of the body.
9. What is the term for the loss of muscle mass and function associated with aging?
a. Sarcopenia
b. Age-induced bioenergetics
c. Hyperplasia
d. Hypertrophy
10. How many minutes of physical activity should children accumulate each day?
a. 15 Minutes
b. 60 minutes
c. 120 minutes
d. 30 Minutes
Explanation / Answer
1. d. HACE occurs when individuals experience headaches and shallow breathing after one hour at high altitude.
2.Acute mountain sickness
3.d. Endocrine glands, sweat glands, blood vessels, and heart.
4.c. During the first trimester, exercise can start at 15 minutes per day, 3 days per week, or as comfort and symptoms dictate.
5.a. Ann should only exercise for 2 hours or less per week.
6. Mark is out for a long run on a hot day. He is dehydrated and does not have water with him. As he tries to maintain a high exercise intensity, his body is likely experiencing the dual cardiovascular demand.
Which two factors make up this demand?
ans:
e. The need to pump additional blood to the surface of the skin
f. The need to pump additional blood to working muscles
When prolonged intense exercise is performed at high ambient temperatures, cardiac output must meet dual demands for increased blood flow to contracting muscle and to the skin.
7. True or false? Children and adolescents can improve bone health with regular physical activity, especially if they focus on high impact activities such as running and repeated jumping.
c. True
8. How does non shivering thermogenesis contribute to thermoregulation?
c. It increases sweat production in hot environments
9. What is the term for the loss of muscle mass and function associated with aging?
a. Sarcopenia (Muscle Loss With Aging)
10. How many minutes of physical activity should children accumulate each day?
b. 60 minutes
