Question 4

Aaron is 5 years old.What does the U.S.Department of Health and Human Services consider to be the most hazardous to his health?

Accepted Answer

Lead poisoning is a major public health concern, especially for children. Lead can damage the brain and nervous system, and can cause learning disabilities, behavioral problems, and other health issues. The U.S. Department of Health and Human Services considers lead poisoning to be the most hazardous to Aaron's health because it is a preventable condition that can have serious lifelong consequences.

Question 5

What is the name of the protective insulation that surrounds parts of neurons and speeds the transmission of electrical impulses along brain cells but also adds to brain weight?

Accepted Answer

The protective insulation that surrounds parts of neurons and speeds the transmission of electrical impulses along brain cells is called myelin. Myelin also adds to the weight of the brain, as it forms a significant portion of the white matter in the brain. Therefore, the correct option is C. The reticular formation (A) is a network of neurons in the brainstem involved in regulating sleep and arousal.

Accepted Answer

Accidents are the greatest risk to the health and well-being of a preschool-age child. This is because they are still learning and exploring their environment, and may not have fully developed their coordination and judgment skills. It is important for caregivers to provide a safe and secure environment and closely supervise young children to prevent accidents. Illness, nutritional problems, and neglect are also concerns, but do not pose as immediate or frequent a risk as accidents.

Question 9

Which of the following most likely contributes to the high level of accidents in the preschool-age group?

Accepted Answer

Question 10

What is the term for body weight that is more than 20% higher than the average weight for a person of a given age and height?

Accepted Answer

Obesity is defined as having a body weight that is more than 20% higher than the average weight for a person of a given age and height. This is different from being overweight, which is defined as having a body weight that is above what is considered healthy for a certain height, but less than 20% higher than the average weight for that height. Underweight refers to having a body weight that is below what is considered healthy for a certain height, while malnutrition refers to a lack of proper nutrients in the diet, regardless of body weight.

Question 11

What does the U.S.Department of Health and Human Services consider to be the most hazardous health hazard to children under the age of 6?

Accepted Answer

Lead can be found in old paint, contaminated soil, and drinking water in some areas. Lead exposure can cause developmental delays, learning difficulties, and other health problems.

Question 12

By the time a child is 6 years old,he/she weighs,on average,about _______ pounds and stands approximately ______ inches tall.

Accepted Answer

According to the CDC growth charts for children ages 2-20 years old, the average weight for a 6-year-old falls between 36-60 pounds, with the median weight being around 46 pounds. The average height for a 6-year-old falls between 39-50 inches, with the median height being around 46 inches. Therefore, choice C is the most accurate answer.

Question 13

Which of the following is considered a permanent result of lead poisoning in children?

Accepted Answer

Lead poisoning in children can lead to permanent damage to the brain and nervous system, resulting in lower intelligence and problems with verbal and auditory language processing. Low weight and inadequate growth/height, loss of appetite, and depression may also be symptoms of lead poisoning, but are not necessarily permanent results.

Question 14

Which of the following may be a factor in how much a preschooler weighs and how tall he/she is?

Accepted Answer

Sex is a biological factor that affects how much weight and height a preschooler gains. Boys tend to gain more weight and height than girls. Other factors such as nutrition, genetics, and environment also play a role, but sex is a significant factor.

Answer: D
 The quality of preschool can indirectly affect a preschooler's weight and height. Children who attend quality preschool programs receive better snacks and lunches, which can lead to a more balanced and nutritious diet. This, in turn, can lead to healthier growth and development. However, other factors such as genetics, environment, and access to healthcare also play a role.

Question 15

What is the term used to describe a caregiver placing covers over electrical outlets,child locks on cabinets,using child car seats,and preventing long-term hazards such as lead poisoning?

Accepted Answer

Question 16

As an infant,Baby Sarah had typical childhood illnesses and no significant earaches.However,Sarah is now 4 years old and she is experiencing frequent earaches.What is the most likely reason for this?

Accepted Answer

The change in the position of the eustachian tube as a child grows can sometimes lead to an increase in earaches. This is a common reason for earaches in preschool-aged children. Options A and B may also be factors, but without more information, it is not clear if these are the primary reasons for Sarah's earaches. Option D is less likely since it is uncommon for a shampoo allergy to cause inflammation in the eustachian tubes.

Question 17

Of all of the different types of preschoolers,which preschooler is two times more likely to die of injuries?

Accepted Answer

According to research, inner-city boys are two times more likely to die of injuries compared to other types of preschoolers.

Question 18

Which of the following is NOT considered a likely source for exposure to lead poisoning?

Accepted Answer

Farm products such as fruits, vegetables, and milk are not considered a likely source for exposure to lead poisoning. However, it is important to note that there are other potential sources of contamination in food, such as pesticides and other environmental contaminants.

Question 19

Because the rate of Alex's growth during preschool years is ____ than during infancy,Alex needs ______ food to maintain his growth.

Accepted Answer

During the preschool years, a child's growth rate slows down compared to the rapid growth experienced during infancy. Therefore, Alex would need less food to maintain his slower rate of growth during this period.
