The skin thins and sags. Wrinkles appear. Secretions from oil and sweat glands decrease. Dry skin and itching occur. The skin is fragile and easily injured. The skin's blood vessels are fragile, increasing the risk for: • Skin breakdown • Skin tears (Chapter 33) • Pressure ulcers (Chapter 34) • Bruising • Delayed healing Brown spots appear on sun-exposed areas. They are called "age spots" or "liver spots." They are common on the wrists and hands. Loss of the skin's fatty tissue layer affects body temperature. The person is more sensitive to cold. Protect the person from drafts and cold. Sweaters, lap blankets, and extra blankets are helpful. So are higher thermostat settings. Dry skin causes itching. It is easily damaged. A shower or bath twice a week is enough for hygiene. Partial baths are taken at other times. Mild soaps or soap substitutes are used to clean the underarms, genitals, and under the breasts. Often soap is not used on the arms, legs, chest, and abdomen. Lotions and creams prevent drying and itching. Deodorants may not be needed because sweat gland secretion is decreased. See Chapter 20 for hygiene. Nails become thick and tough. Feet usually have poor circulation. A nick or cut can lead to a serious infection. See Chapter 21 for nail and foot care. The skin has fewer nerve endings. This affects sensing heat, cold, pressure, and pain. Burns are great risks. Fragile skin, poor circulation, and decreased sensing of heat and cold increase risk of burns. Older persons often complain of cold feet. Socks provide warmth. Do not use hot water bottles and heating pads because of the risk for burns. White or gray hair is common. Hair loss occurs in men. Hair thins on men and women. Thinning occurs on the head, in the pubic area, and under the arms. Women and men may choose to wear wigs. Some color hair to cover graying. Facial hair (lip and chin) may occur in women. Hair is drier from decreases in scalp oils. Brushing promotes circulation and oil production. Shampoo frequency depends on personal choice. Usually it decreases with age. It is done as needed for hygiene and comfort. Skin disorders increase with age. They rarely cause death if treated early. The risk of skin cancers increases with age. Prolonged sun exposure is a cause. Skin changes can be seen. Gray hair, hair loss, brown spots, wrinkles, and sagging skin are some examples. These changes can affect selfesteem and body image. The Musculo-Skeletel System Muscle cells decrease in number. Muscles atrophy (shrink). They decrease in strength. Bones lose minerals, especially calcium. Bones lose strength. They become brittle and break easily. Sometimes just turning in bed can cause fractures (broken bones). Vertebrae shorten. Joints become stiff and painful. Hip and knee joints flex (bend) slightly. These changes cause gradual loss of height and strength. Mobility also decreases. Older persons need to stay active. Activity, exercise, and diet help prevent bone loss and loss (of muscle strength. Walking is good exercise. Exercise groups and range-of-motion exercises are helpful (Chapter 27). A diet high in protein, calcium, and vitamins is needed. Bones can break easily. Protect the person from injury and falls (Chapters 12 and 13). Turn and move the person gently and carefully (Chapter 17). Some persons need help and support getting out of bed. Some need help walking. The Nervous System Nerve cells are lost. Nerve conduction and reflexes slow. Responses are slower. For example, an older person slips. The message telling the brain of the slip travels slowly. The message from the brain to prevent the fall also travels slowly. The person falls. Blood flow to the brain is reduced. Dizziness may occur. It increases the risk for falls. Practice measures to prevent falls (Chapter 13). Remind the person to get up slowly from 2 Mosby’s Textbook For Nursing Assistants CHAPTER 11 Care of the Older Person bed or chair. This helps prevent dizziness (Chapter 27). Changes occur in brain cells. This affects personality and mental function. So does reduced blood flow to the brain. Memory is shorter. Forgetfulness increases. Responses slow. Confusion, dizziness, and fatigue may occur. Older persons often remember events from long ago better than recent ones. Many older people are mentally active and involved in current events. They show fewer personality and mental changes. (See Chapter 46 for confusion and dementia.) Sleep patterns change. Falling asleep is harder for older persons. Sleep periods are shorter. They wake often at night and have less deep sleep. Less sleep is needed. Loss of energy and decreased blood flow may cause fatigue. They may rest or nap during the day. They may go to bed early and get up early. The Senses. Aging affects touch, smell, taste, sight, and hearing. Touch. Touch and sensitivity to pain and pressure are reduced. So is sensing heat and cold. These changes increase the risk for injury. The person may not notice painful injuries or diseases. Or the person feels minor pain. You need to: Protect older persons from injury (Chapters 12 and 13). Follow safety measures for heat and cold (Chapter 35). Check for signs of skin breakdown (Chapters 20, 33, and 34). Give good skin care (Chapter 20). Prevent skin tears (Chapter 33) and pressure ulcers (Chapter 34) Taste and smell. Taste and smell dull. Appetite decreases. Taste buds decrease in number. The tongue senses sweet, salty, bitter, and sour tastes. Sweet and salty tastes are lost first. Older people often complain that food has no taste or tastes bitter. They like more salt and sugar on food. The eye. Eyelids thin and wrinkle. Tear secretion is less. Dust and pollutants can irritate the eyes. The pupil becomes smaller and responds less to light. Vision is poor at night or in dark rooms. The eye takes longer to adjust to lighting changes, causing vision problems when: Going from a dark to a bright room Going from a bright to a dark room Clear vision is reduced. Eyeglasses are often needed. The lens of the eye yellows, making greens and blues harder to see. Older persons become more farsighted. This is called presbyopia. (Presby relates to aging. Opia means eye.) The lens becomes more rigid with age. It is harder for the eye to shift from far to near vision and from near to far vision. These changes increase the risk of falls and accidents. The risk is greater on stairs and where lighting is poor. Eyeglasses are worn as needed. Keep rooms well-lit. Nightlights help at night. The ear. Changes occur in the acoustic nerve. Eardrums atrophy. High-pitched sounds are hard to hear. Severe hearing loss occurs if these changes progress. A hearing aid may be needed. It must be clean and correctly placed in the ear. Wax secretion decreases. Wax becomes harder and thicker. It is easily impacted (wedged in the car). This can cause hearing loss. A doctor or nurse removes the wax. The Circulatory System The heart muscle weakens. It pumps blood with less force. Problems may not occur at rest. Activity, exercise, excitement, and illness increase the body's need for oxygen and nutrients. A damaged or weak heart cannot meet these needs. Arteries narrow and are less elastic. Less blood flows through them. Poor circulation occurs in many body parts. A weak heart works harder to pump blood through narrowed vessels. Exercise helps maintain health and wellbeing. Many older persons exercise daily. They walk, jog, golf, and bicycle. They also hike, ski, play tennis, swim, and play other sports. Older persons need to be as active as possible. Sometimes circulation changes are severe. Rest is needed during the day. Over-exertion is avoided. The person should not walk far, climb 3 Mosby’s Textbook For Nursing Assistants CHAPTER 11 Care of the Older Person many stairs, or carry heavy things. Personal care items, TV, phone and other needed items are kept nearby. Some exercise helps circulation. It also prevents blood clots in leg veins. Some persons need to stay in bed. They need range-ofmotion exercises (Chapter 27). Doctors may order certain exercises and activity limits. The Respiratory System Respiratory muscles weaken. Lung tissue becomes less elastic. Often lung changes are not noted at rest. Difficult, labored, or painful breathing (dypsnea) may occur with activity. (Dys means difficult. Pnea means breathing.) The person may lack strength to cough and clear the airway of secretions. Respiratory infections and diseases may develop. These can threaten life. Normal breathing is promoted. Avoid heavy bed linens over the chest. They prevent normal chest expansion. Turning, re-positioning, and deep breathing are important. They help prevent respiratory complications from bedrest. Breathing usually is easier in semi-Fowler's position (Chapter 18). The person should he as active as possible. The Digestive System Saliva glands produce less saliva. This can cause difficulty in swallowing (dysphagia). (Dys means difficult. Phagia means swallowing.) Dry foods may be hard to swallow. Taste and smell dull. This decreases appetite. Secretion of digestive juices decreases. This makes fried and fatty foods hard to digest. This may cause indigestion. Loss of teeth and ill-fitting dentures cause chewing problems. This causes digestion problems. Hard-to-chew foods are avoided. Ground or chopped meat is easier to chew and swallow. Dry, fried, and fatty foods are avoided. This helps swallowing and digestion problems. Oral hygiene and denture care improve taste. Some people do not have teeth or dentures. Their food is pureed or ground. Peristalsis decreases. The stomach and colon empty slower. Flatulence and constipation can occur (Chapter 23). High-fiber foods help prevent constipation. However, they are hard to chew and can irritate the intestines. They include apricots, celery, and fruits and vegetables with skin and seeds. Persons with chewing problems or constipation often need foods that provide soft bulk. They include whole-grain cereals and cooked fruits and vegetables. Fewer calories are needed. Energy and activity levels decline. More fluids are needed for chewing, swallowing, digestion, and kidney function. Foods are needed to prevent constipation and bone changes. High-protein foods are needed for tissue growth and repair. However, some older persons lack protein in their diets. High-protein foods (meat and fish) are costly. The Urinary System Kidney function decreases. The kidneys shrink. Blood flow to the kidneys is reduced. Waste removal is less efficient. The ureters, bladder, and urethra lose tone and elasticity. Bladder muscles weaken, Bladder size decreases, storing less urine. Urinary frequency or urgency may occur. Many older persons have to urinate (void) during the night. Urinary incontinence (the loss of bladder control) may occur (Chapter 22). In men, the prostate gland enlarges. This puts pressure on the urethra. Difficulty voiding or frequent urination occurs. Urinary tract infections are risks. Adequate fluids are needed. The person needs water, juices, milk, and gelatin. Provide fluids according to the care plan. Remind the person to drink. Offer fluids often to those who need help. Most fluids should be taken before 1700 (5:00 PM). This reduces the need to void during the night. Persons with incontinence may need bladder training programs. Sometimes catheters are needed (Chapter 22). 4
