Question 1

How many hours of sleep do medical authorities recommend getting each night?

Accepted Answer

Medical authorities recommend getting 7 to 9 hours of sleep each night for optimal health and well-being.

Question 2

In what condition do the bones become thin and brittle as a result of rapid calcium depletion?

Accepted Answer

Osteoporosis is a condition where bones become thin and brittle due to rapid calcium depletion, making them more susceptible to fractures. Atherosclerosis is a condition where plaque builds up in arteries, causing them to narrow and harden. Ossicle depletion and phosphoritis are not recognized medical conditions.

Question 3

Your grandmother is a 56-year-old smoker and just read an article concerning osteoporosis. The article did not really cover much, just stated that the likelihood of osteoporosis increases with age. What would you say to her about her risk factor? She should ____.

Accepted Answer

Smoking is a significant risk factor for osteoporosis, as it accelerates bone loss. Yearly bone density checks can help monitor bone health and catch any issues early on. Quitting smoking can also help reduce the risk of osteoporosis. Drinking milk and starting an exercise routine can be helpful for preventing osteoporosis, but they may not be enough for someone with multiple risk factors such as smoking and advanced age.

Question 4

Which of the following pairs of individuals have a higher concordance rate of osteoporosis than the rest?

Accepted Answer

Monozygotic twins have a higher concordance rate of osteoporosis than dizygotic twins, biological sisters, and adopted sisters because they share 100% of their genetic material, whereas dizygotic twins, biological sisters, and adopted sisters share only a portion of their genes. Therefore, the environmental factors have a greater impact on the latter groups, resulting in a lower concordance rate.

Question 5

Medical authorities recommend ____ of sleep per night as optimal, but among midlife adults in the United States, more than ____ report receiving less than 7 hours of sleep at least occasionally.

Accepted Answer

Medical authorities recommend 7-9 hours of sleep per night as optimal, and more than one-fourth (25%) of midlife adults in the United States report receiving less than 7 hours of sleep at least occasionally. Therefore, option C is the best choice.

Question 6

What is the risk factor for osteoporosis?

Accepted Answer

Smoking is a risk factor for osteoporosis, as it can decrease bone density and increase the risk of fractures. Eating soy-based foods, too much exercising, and obesity are not necessarily risk factors for osteoporosis.

Question 7

In what condition do the bones become thin and brittle as a result of rapid calcium depletion?

Accepted Answer

Osteoporosis is a condition in which bones become thin and brittle as a result of rapid calcium depletion, making them more susceptible to fractures. Scoliosis is a condition characterized by an abnormal curvature of the spine. Jaundice is a condition in which the skin, whites of the eyes, and mucous membranes turn yellowish as a result of high levels of bilirubin. Diabetes is a condition in which the body is unable to properly regulate blood sugar levels. None of these conditions are related to rapid calcium depletion or thinning and weakening of bones.

Question 8

Evolutionary biologist Jared Diamond (1992) hypothesised that the danger that childbirth poses to human mothers, and the danger that a mother's death poses to human children, were related to what characteristically human experience?

Accepted Answer

Jared Diamond hypothesized that menopause evolved in humans because it allows women to live long enough to care for their grandchildren, thus increasing the survival chances of their genes. This relates to the danger of childbirth and the importance of a mother's survival for the child's well-being.

Question 9

By age 40 years, many individuals in midlife experience sleep problems. What are the consequences? Adults in midlife are ____.

Accepted Answer

By age 40, individuals are already experiencing a reduction in slow wave or deep sleep, which is associated with physical restoration and cognitive functioning. Therefore, adults in midlife are less likely to experience the deepest type of sleep.

Question 10

How often do health authorities recommend that women over 50 have their bone density checked?

Accepted Answer

The answer of How often do health authorities recommend that...

Question 11

What is unique to human females during midlife that does not happen to any other primate species?

Accepted Answer

Menopause is unique to human females during midlife and does not occur in any other primate species.

Question 12

Eighty percent of people who are diagnosed with osteoporosis are women. What is the simple explanation for this phenomenon?

Accepted Answer

During menopause, women lose oestrogen and this puts women at a greater risk for the development of osteoporosis.

Question 13

Which of the following is the leading cause of death for adults worldwide?

Accepted Answer

Cardiovascular disease is the leading cause of death for adults worldwide, accounting for approximately 17.9 million deaths annually. Starvation and war, while significant issues, do not have as high of a death toll on a global scale. Cancer is a close second to cardiovascular disease, but statistics show that cardiovascular disease is the number one cause of death globally.

Question 14

Your 46-year-old uncle is about 60 pounds overweight and is having difficulty sleeping at night. If he were interested in your advice, you could tell him that ____.

Accepted Answer

Being overweight can contribute to difficulty sleeping, particularly sleep apnea, which can cause interruptions in breathing during sleep. Losing weight can improve overall health and lead to better sleep quality. It is important for your uncle to speak to a healthcare professional about his weight and sleeping issues to develop a safe and effective plan for weight loss and symptom management. The other options provided are not accurate or helpful advice.

Question 15

During middle adulthood, which of the following are factors related to sleep disturbances and sleep disorders?

Accepted Answer

Obesity, cardiovascular disease, and depression are all common factors related to sleep disturbances and sleep disorders in middle adulthood. Arthritis, jaundice, diabetes, restless legs syndrome, myopic vision, hypertension, anxiety, eczema, and psoriasis may also contribute to poor sleep quality, but they are not as strongly associated with sleep disturbances and sleep disorders as obesity, cardiovascular disease, and depression.

Question 16

From middle adulthood onward, women lose about what percentage of their bone mass?

Accepted Answer

Women lose about 50% of their bone mass from middle adulthood onward due to decreased levels of estrogen.

Question 17

What is a problem that is commonly experienced by individuals in midlife who are obese, have cardiovascular disease or who are depressed?

Accepted Answer

Sleep problems are commonly experienced by individuals in midlife who are obese, have cardiovascular disease, or who are depressed. Obesity, cardiovascular disease, and depression can all contribute to sleep disturbances such as insomnia or sleep apnea. Poor sleep has been linked to a range of negative health outcomes, including increased risk of cardiovascular disease, depression, and obesity, creating a vicious cycle.

Question 18

Your 59-year-old uncle is convinced that he will have osteoporosis. He is in good health and is quite active. What would you tell him?

Accepted Answer

While osteoporosis is more commonly associated with women, it can still affect men. However, only 20% of individuals with osteoporosis are male, making it less likely that your uncle will develop osteoporosis solely based on his gender. It is important to note that there are other risk factors for osteoporosis, such as age, family history, and lifestyle factors such as smoking and excessive alcohol use. Encouraging your uncle to maintain his active lifestyle and consume a healthy diet, including adequate calcium and vitamin D, can help reduce his risk of osteoporosis.

Question 19

At what rate do testosterone levels decline during midlife?

Accepted Answer

The answer of At what rate do testosterone levels decline...

Question 20

Your father, who is 45 years old, has recently been discussing the desire to father another child. He is worried that he will not able to do so even though he and your mother are strongly considering it. What would you tell him regarding his ability to father another child? He should _____.

Accepted Answer

While fertility decreases somewhat as men age, many men are still capable of fathering a child at 45 years old. Sperm quality and mobility do decrease with age, but it is not an automatic barrier to fatherhood. It may be moderately more difficult to conceive a child at this age, but it is certainly not impossible.
