Question 2

Exercise is related to all of the following positive outcomes in adolescence,EXCEPT:

Accepted Answer

Question 4

Research has shown that infants born to adolescent mothers are more likely to have:

Accepted Answer

Research has shown that infants born to adolescent mothers are more likely to have childhood illnesses such as respiratory infections, gastrointestinal infections, and ear infections. This is likely due to the mother's lack of experience and knowledge in caring for an infant, as well as socioeconomic factors that may limit access to healthcare and proper nutrition. High birth weight is more commonly associated with maternal obesity or gestational diabetes, Down syndrome is a genetic disorder not related to maternal age, and type II diabetes is a long-term metabolic disorder that develops later in life.

Question 6

A number of leading experts on adolescent sexuality conclude that education programs that emphasize contraceptive knowledge:

Accepted Answer

Several studies have found that programs emphasizing contraceptive knowledge do not increase the incidence of sexual intercourse among adolescents. These programs have also been found to be effective in increasing condom use and reducing the incidence of sexually transmitted infections when used in conjunction with education about abstinence. However, some studies suggest that these programs may not be as effective in reducing the risk of adolescent pregnancy as abstinence-only programs.

Question 7

Question 9

Mary Carskadon and her colleagues concluded from their research of the sleep patterns of U.S.adolescents that:

Accepted Answer

Mary Carskadon and her colleagues found that early school starting times may be linked to negative outcomes for adolescents. Specifically, they found that many U.S. adolescents are not getting enough sleep, and this lack of sleep is associated with a range of negative outcomes including a decline in academic performance, mood disturbances, and an increased risk of accidents and injuries. The researchers recommended that schools consider starting classes later in the morning to better align with adolescents' natural sleep patterns.

Question 10

One strategy for reducing adolescent pregnancy is the _____ that focuses on engaging adolescents in volunteer community service and stimulates discussions that help adolescents appreciate the lessons they learn through volunteerism.

Accepted Answer

The Teen Outreach program is designed to reduce adolescent pregnancy by involving teens in community service and discussions, helping them learn valuable life lessons and develop a sense of responsibility.

Question 11

A recent national study revealed that approximately _____ percent of U.S.15-year-olds met the federal government's exercise recommendations (a minimum of 60 minutes of moderate to vigorous exercise per day).

Accepted Answer

The study found that only about 29% of U.S. 15-year-olds met the federal exercise recommendations.

Question 12

In the United States,_________ percent of pregnancies to mothers 15 to 19 years of age are unintended.

Accepted Answer

According to data from the Guttmacher Institute, 82 percent of pregnancies to mothers 15 to 19 years of age are unintended in the United States.

Question 13

Which of the following describes the federal government's exercise recommendations?

Accepted Answer

The federal government's exercise recommendations call for a minimum of 60 minutes of moderate to vigorous exercise per day for children and adolescents, and at least 150 minutes per week of moderate-intensity exercise or 75 minutes per week of vigorous-intensity exercise for adults. Option A and D suggest very low levels of physical activity, while option B suggests a low limit on exercise which is not accurate.

Question 14

A number of leading experts on adolescent sexuality conclude that abstinence-only programs:

Accepted Answer

Studies have shown that abstinence-only programs are less effective at reducing the risk of adolescent pregnancy than sex-education programs. These programs often neglect to provide information about contraception and safer sex practices, leaving teens uninformed and unprepared to make responsible decisions about their sexual health.

Question 15

Daughters of teenage mothers are:

Accepted Answer

Daughters of teenage mothers are at increased risk for teenage childbearing themselves. This is due to a variety of factors, including lack of access to effective contraception, lack of education about safe sex practices, and a cultural environment that may normalize teenage pregnancy.

Question 16

Which of the following ethnic groups had the highest teen birth rate in 2009?

Accepted Answer

In 2009, the Latino ethnic group had the highest teen birth rate in the United States compared to other ethnic groups.

Question 17

According to a national survey,_____ boys exercised the most,_____ girls the least.

Accepted Answer

The survey states that non-Latino White boys exercised the most, while African American and Latino girls exercised the least. Therefore, the best choice is D, which includes both non-Latino White and African American and Latino groups.

Question 18

Mary Carskadon and her colleagues' research on adolescent sleep patterns found that:

Accepted Answer

Mary Carskadon's research found that adolescents will sleep an average of 9 hours and 25 minutes a night when given the opportunity, which is more than the commonly believed 8 hours. Choice B is incorrect because older adolescents actually experience a shift in their biological clocks that makes them feel sleepy an hour later than younger adolescents. Choice C is incorrect because Carskadon's research found that younger adolescents tend to be more alert during the day than older adolescents. Choice D is also incorrect because the increased sleepiness in adolescents during the day was found to be primarily a result of their biological need for more sleep and not solely due to academic work or social pressures.

Question 19

The majority of unintentional injuries in adolescence involve:

Accepted Answer

Motor vehicle accidents are the leading cause of unintentional injuries in adolescence, accounting for more than half of all unintentional injury deaths in this age group. Firearms and homicide are also serious concerns, but do not occur as frequently as motor vehicle accidents. Sports-related injuries are also common, but typically do not result in fatalities to the same extent as motor vehicle accidents.

Question 20

Based on data from 2011,which of the following individuals was most likely to get pregnant as a teen?

Accepted Answer
