Dental Caries

Tooth decay, loose teeth, and lost teeth-ongoing problem Poor nutrition & decreased appetite-often caused by

dental problems Decay [caries/cavites]-caused by bacteria

penetrates through enamel that protects tooth Destruction of inner structures of tooth

infection

3

caries

Periodontal Disease

less obvious than caries potentially more serious

complication of poor oral care Food debris & plaque build up in mouth & on teeth

Bacteria multiply-lots of “food “ for them Disrupts “seal” between gum and tooth Infection; bone loss

bacteria cause bad breath, or halitosis. disturbing to the older person and anyone in close contact

8

Periodontal Disease (cont.)

Gingivitis-the beginning of periodontal disease gum swelling, tenderness, and bleeding eventually recession of gum tissue away from the tooth

11

Healthy gums

Gingivitis

Gingivitis with some recession

Pain

caries & periodontal disease most common reason for oral pain Sometimes oral lesions, stomatitis

may be limited to mouth or may affect the face and jaw can cause loss of appetite, decreased food/fluid intake negative effect on the overall quality of life

17

Dentures

Partial plates-tend to catch particles of food-can weaken healthy teeth

Complete dentures-difficult to fit Dentures may not fit properly if a significant amount of

weight is gained or lost Dentures can cause irritation, inflammation, and

ulceration of gums and oral mucous membranes

18

Dry Mouth

Xerostomia, or dry mouth is common normal age-related reduction in saliva medication side effects inadequate hydration diseases such as diabetes

Makes chewing and swallowing more difficult, promotes tooth decay, and alters the sense of taste

22

Leukoplakia

White patches in the mouth Often are precancerous and require prompt medical

attention Can also be med s/e or thrush Lesions on the posterior third or sides of the tongue

often are abnormal and should be brought to the attention of the physician

23

Leukoplakia (cont.)

24

A disease that is suspected to play a role in thromboembolic disorders, bacterial endocarditis, and myocardial infarction is:A. dental caries.B. halitosis.C. gingivitis.D. periodontal disease.

25

Cancer

Oral or pharyngeal cancer have poor prognosis Early recognition and treatment before mets to other

tissues offer the best hope Symptoms- include leukoplakia or erythroleukoplakia,

sores in the mouth that do not heal, oral bleeding, pain or difficulty swallowing, difficulty wearing dentures, swollen lymph nodes in the neck, earache

26

Disorders Caused by Vitamin Deficiencies

deficiencies of riboflavin, niacin, and vitamin C can affect oral mucous membranes

A smooth purplish sore tongue may be related to riboflavin deficiency

Complaint of a burning sensation or soreness of the mouth may indicate niacin deficiency

27

Superinfections

relatively common Caused by broad-spectrum antibiotic therapy for some

other infection Antibiotics destroy the normal mouth flora allow opportunist bacteria or yeast colonies to become

established and grow

28

Superinfections (cont.)

A hairy tongue result of enlargement of the papillae on the tongue often follows antibiotic therapy

Black or brown discoloration on the tongue may be caused by tobacco use or by a chromogenic (color-producing) bacterium

29

Alcohol- and Tobacco-Related Problems

Alcohol and tobacco, even in small amounts, can harm the mucous membranes

Alcohol- chemically irritating and drying to the mucous membranes

Tobacco- smoked, chewed, or snuff, increases risk for oral cancer

32

Problems Caused by Neurologic Conditions

Neuro conditions such as stroke, multiple sclerosis, or Parkinson’s disease decrease coordination and strength difficult to manipulate toothbrush & floss Can be difficult to open mouth Difficult to raise arm[s]

33

Problems Caused by Neurologic Conditions (cont.)

severe arthritis-equipment difficult to manipulate difficult to open the mouth Can’t hold toothbrush or floss Raise arms to be able to get to mouth

medication for seizure or other neuro disorders need to use special precautions medications often cause gum problems

34

Nursing Interventions for Impaired Oral Mucous Membranes

Complete a thorough assessment of the oral mucous membranes

Initiate referral to a dentist or dental hygienist Provide oral hygiene

35

Nursing Interventions for Impaired Oral Mucous Membranes (cont.)

Promote adequate intake of nutrients and fluids lozenges or topical analgesics as prescribed Report suspected side effects of medication therapy to

the physician and dentist

36

Dental care

Access to dental care is often an issue for people with impaired mobility Getting to the office Ability to tolerate time in wheel chair/use walker Getting on to the chair Ability to cooperate with personnel Ability to open their mouth

Chapter 18Elimination

38

Objectives

Describe normal elimination processes. Identify people who are most at risk for problems with

elimination. Describe age-related changes in bladder and bowel

elimination.

39

Normal Elimination Patterns

40

Bowel Elimination

typical adult: moderate amount formed brown stool passed without

difficulty every 1- 2 days urge usually occurs 30 to 45 minutes p meal

gastrocolic and defecation reflexes stimulate peristalsis

41

Urinary Elimination

Usual adult: urge when bladder has about 300 mL of urine

This varies greatly Voluntary control of external sphincter

allows healthy adults to hold larger amounts until it’s convenient

Most adults void between 6 and 10 times per day

42

Elimination and Aging

44

Constipation

Hard, dry stools- difficult to passIncreased risk associated with aging

decreased abdominal muscle toneInactivity &/or immobilityinadequate fluid intake

Especially combined with bulk forming agents [metamucil]

46

Constipation

inadequate dietary bulkdisease conditions [parkinsons, gastroparisis +

more]Medicationsdependence on laxatives or enemasvarious environmental conditions

Inability to get to toiletholding too long, lack of privacy

47

Constipation (cont.)

Dietary fiber-important role in promoting normal eliminationindigestible substance traps moisture & provids

bulk Repeatedly ignoring the urge to defecate can lead to problems with defecation reflex

48

Fecal Impaction

mass of hardened feces trapped in the rectum & can’t be passed result of unrelieved constipation

Symptoms longer-than-usual delay in defecation Passage of small amounts of liquid stool without any formed

fecal material Digital examination of the rectum may reveal presence

of a hardened mass of feces

50

Objectives

Discuss methods for assessing elimination practices. Identify selected nursing diagnoses related to elimination

problems. Describe interventions used to prevent or reduce

problems related to elimination.

53

Nursing Interventions for Constipation

Assess bowel elimination patterns and contributing factors

Increase physical activity Increase intake of dietary fiber and fluids Schedule or encourage toileting at times when the

person’s defecation urge is strongest r/t meals Cup of warm liquid in am

Position to facilitate ease of elimination Provide privacy for elimination

54

Nursing Process for Diarrhea

55

Diarrhea

Frequent passage of liquid, unformed stools Stools are liquid because they pass through the large intestine too

rapidly and are expelled before sufficient water can be absorbed in the large intestine

Symptom of another problem many causes

malabsorption syndromes Obstruction- tumors of the GI tract or stool lactose intolerance Diverticulosis pathogenic organisms medications

57

Nursing Interventions for Diarrhea

Assess the elimination pattern and suspected causative factors

Maintain adequate fluid intake Institute measures to maintain skin integrity Promptly report observations to the physician, and follow

up on physician’s orders regarding medications that decrease intestinal motility

Stool testing as ordered

59

Bowel Incontinence

common for those who are unable to recognize &/or respond to normal sensation mental impairment Mobility Delayed assistance

Less frequently disorders of color or rectum Cancer inflammatory bowel disease Diverticulitis weak rectal muscles diarrhea

60

Nursing Goals/Outcomes

Exhibit regular patterns of bowel elimination Identify behaviors that promote normal bowel

functioning Modify behaviors to enhance regular bowel elimination

61

Nursing Interventions

Assess patterns of elimination and causative factors Establish a toileting schedule

Bowel training program Take measures to prevent or reduce episodes of

constipation Use appropriate aids or garments Clean the person promptly after each episode of

incontinence

62

Nursing Process for Impaired Urinary Elimination

63

Urinary Retention

Abnormal accumulation of urine in the bladder; bladder unable to empty completely Normally, no more than 50 mL of urine remains in the bladder after voiding

decreased muscle tone in the bladder wall medications prostate gland enlargement/uterine prolapse trauma to the muscles of the perineum neurologic problems anxiety Decreased fluid intake

65

Urinary Retention (cont.)

Symptoms feeling of fullness, discomfort, or tenderness Small frequent voids Frequent bladder infections Restlessness diaphoresis

66

Urinary Retention Treatment

If caused by perineal trauma or anxiety noninvasive tx such as medications, peppermint oil [inhaled scent] or a

sitz bath may be enough to stimulate effective voiding If severe retention is caused by an obstruction such as an

enlarged prostate, catheterization or surgery may be necessary prevent serious bladder damage that could result from persistent or

excessive bladder distention Pessarys were once commonly used with uterine prolapse, now

usual tx is surgery

71

Urinary Incontinence

The involuntary loss of urine social or hygiene problem

In some cases, incontinence is curable using surgery ,medications, or other treatments

Kegel exercises In others- better managed, thus allowing the older

person a more normal lifestyle

72

Types of Urinary Incontinence

Stress incontinence Leakage of urine

conditions that increase intra-abdominal pressure exercise, lifting heavy objects, laughing, coughing, or sneezing

Urge incontinence Caused by involuntary contraction of the detrusor muscle of

the bladder Overflow incontinence

Leakage of small amounts of urine from an overly full bladder

Common with retention problems

73

Types of Urinary Incontinence (cont.)

Functional incontinence normal urethral and bladder function cognitive or physical in nature

Total incontinence A condition in which older adults experience continuous and

unpredictable loss of urine

74

Nursing Goals/Outcomes

Exhibit a reduction in episodes of urinary incontinence or retention

Urinate at acceptable times in acceptable places Identify measures that reduce episodes of urinary

incontinence or retention Ie-toilet every 2 hours Bladder training program

Establish a routine to reduce or prevent the occurrence of bladder elimination problems

75

Nursing Interventions

Assess elimination and fluid intake patterns Explain measures that help improve tone of the

sphincter muscles Kegel exercises

Modify clothing to make toileting easier Reduce environmental barriers

grab bars in the bathroom, installing toilet risers, keeping the urinal or bedpan readily available, and providing a call signal for assistance

76

Nursing Interventions (cont.)

Answer call signals promptly Develop a toileting schedule Familiarize older adults with the locations of bathrooms

throughout the facility Provide support and encouragement Initiate actions to maintain skin integrity Provide incontinence pads or garments when appropriate

77

Disposable and Reusable Incontinence Garments
