Answer 19

Crying

Question 20

The pace at which infants develop relationships with their parents or caregivers varies greatly from one child to the next.
Bonding, the formation of a close, personal relationship, is generally fostered by a___, which results when the infant understands that his or her parents/caregivers will respond to his or her needs. Having this confidence that his or her parents will provide a “safety net” inspires the child to venture out and explore.

Answer 20

secure attachment

Question 21

The___ is displayed when something touches the neonate’s cheek and he or she intuitively turns his or her head in the direction of the touch.

Answer 21

rooting reflex

Answer 23

fontanelles

Question 24

By contrast,___ is the result of recurring rejection. Infants who acquire this form of attachment show little emotional response to their parents/caregivers and treat them as they would a stranger. These children may compensate by developing an isolated lifestyle wherein they avoid having to depend on the support and care of others.

Answer 24

anxious-avoidant attachment

Question 25

In older infants,___ is common. Characterized by clingy behavior and fear of unfamiliar places and people, it typically reaches its peak between the ages of 10 and 18 months. Crying as a means of protest is normal at this age. As they grow accustomed to their homes and families, infants have an inherent need for a secure, stable environment. An environment that is too unpredictable may trigger feelings of despair, causing the child to become withdrawn. This experience may even lead to trust issues later in life.

Answer 25

separation anxiety

Question 26

___refers to the stage of psychosocial development beginning at birth and concluding at approximately 18 months of age. As the name implies, it is a time when children learn whether they can trust the people around them. Because infants depend entirely on their parents/caregivers, a crucial element in the formation of this trust is the quality of care the infant receives from them. When their needs are met consistently in a stable environment, children learn to trust those responsible for their well-being. Conversely, if their parents/caregivers are inconsistent, emotionally unavailable, or rejecting, children may develop a sense of mistrust

Answer 26

Trust versus mistrust

__(61 Years and Older): • In the early 1900s, the average human life expectancy was 47 years of age. • In more modern times, that number has increased to approximately 78 years, with a maximum life expectancy of approximately 120 years, leading to more older adults (61 years and older). How long an individual lives is determined by many factors, including: • Birth year • Country of residence • Thanks to medical advances, older adults are often able to overcome numerous medical conditions but may need multiple medications to do so.

Answer 57

Older Adults

Question 58

Cardiac function declines with age as a result of anatomic and physiologic changes largely related to atherosclerosis. • Cholesterol and calcium build up inside the walls of coronary blood vessels, forming plaque, which leads to a partial or complete blockage of blood flow. • More than 60% of people older than 65 years have atherosclerotic disease, leading to decreased blood supply to the organs of the body. Other age-related changes typically include: • Decrease in heart rate. • Decline in cardiac output. • Inability to elevate cardiac output to match the demands of the body. • Because heart muscle may weaken with age, the increase in heart rate can damage the heart. • The vascular system becomes stiff and diastolic blood pressure increases. • Bone marrow is replaced with fatty tissue. • Results in a decrease in the ability of the bones to manufacture more blood cells.

Answer 58

Older adults

Question 59

A disorder in which cholesterol and calcium build up inside the walls of blood vessels, eventually leading to partial or complete blockage of blood flow

Answer 59

Atherosclerosis

Question 60

The size of the airway increases and the surface area of the alveoli decreases. • As the elasticity of the lungs decreases, the overall strength of the intercostal muscles and diaphragm decreases. • This rigidity makes the chest more fragile. • The older person will then have less respiratory reserve to use to maintain adequate breathing. The structures that protect the upper airway decrease in function. Results in making it more difficult to maintain the upper airway, resulting in a greater risk of aspiration and airway obstruction. • Collapsing airways result in low flow rates and air trapping, because air does not completely exit the alveoli (incomplete expiration). Immune cells are less functional, leading to an increased risk of lung infections. By age 75, vital capacity decreases and residual volume (the amount of air left in the lungs after expiration of the maximum possible amount of air) increases with age. • Vital capacity may amount to only 50% of the vital capacity of a young adult. Factors contributing to this decline include: • Loss of respiratory muscle mass. • Increased stiffness of the thoracic cage. • Decreased surface area available for the exchange of air.

Answer 60

Older adults

Question 61

Glucose metabolism slows, while insulin production decreases. • Sexually, men continue to produce sperm long into their 80s (although the rigidity of the penis typically diminishes over time). The size of a woman's uterus and vagina decreases. Hormone production in both sexes gradually declines.

Answer 61

Older adults

Question 62

Taste bud sensitivity to salty and sweet sensations decreases. Saliva secretion decreases, which reduces the body's ability to process complex carbohydrates. Older people may have loss of teeth that impacts their ability to chew. The ability of the intestines to contract and move food along diminishes. Gastric acid secretion diminishes. Blood flow may drop by as much as 50%, decreasing the ability of the intestines to extract vitamins and minerals from digested food. Gallstones become increasingly common. Anal sphincter changes reduce elasticity and can produce fecal incontinence.

Answer 62

Older adults

Question 63

Filtration function declines by 50% from age 20 to 90 years. • Kidney size decreases by 20%, due in part to the decreased effectiveness of the blood vessels that supply blood to the nephrons. • Loss of renal function means: • A decrease in the ability to clear waste from the body. • A decreased ability to conserve fluids when needed.

Answer 63

Older adults

Question 64

The basic filtering units in the kidneys

Answer 64

Nephrons

Question 65

Brain weight shrinks 10% to 20% by age 80. Motor and sensory neural networks become slower and less responsive. The metabolic rate in the older brain does not change and oxygen consumption remains constant throughout life. Brain cells (neurons) decrease, but there is great flexibility in the operation of the brain. • Interconnections between brain cells continue as people age and provide redundancy, allowing for loss of neurons without loss of knowledge or skill. Sleep patterns change. • Age-related shrinkage creates a void between the brain and the outermost layer of the meninges, which creates room for the brain to move when stressed. Functioning of the peripheral nervous system slows. Sensation becomes diminished and misinterpreted. Kinesthetic sense diminishes. Slower reactions cause longer delays between stimulation and motion. • Nerve endings deteriorate. • The ability of the skin to sense the surroundings fails.

Answer 65

Older adults

Question 66

Pupillary reaction and ocular movements become more restricted. • Pupils are smaller, and the opacity of the eye's lens diminishes visual acuity and makes the pupils sluggish when responding to light. • Visual distortions are common. • Hearing loss is four times more common than loss of vision in late adulthood. • Changes in several hearing-related structures may lead to a loss of high-frequency hearing or even deafness.

Answer 66

Older adults

Question 67
