Q

Facts about the Musculoskeletal system:

A

-The human body has 206 bones.

-Two bones meet at joint (for movement). Joints make movement possible in either all directions or in one direction only.

-Muscles provide movement and produce body heat.

-Physical activity/exercise increases circulation= increasing blood flow to organs and tissues.

-Inactivity can cause depression, pneumonia, constipation, UTIs, loss of self-esteem, and blood clots. = every body system is affected negatively by inactivity

-Muscles develop atrophy or contractures from inactivity.

-ROM exercises ( range of motion ) help prevent atrophy or contractures.

42
Q

Normal changes of aging in the musculoskeletal system:

A

*Muscles weaken, begin to sag and loose tone = increase risk of falls

*Body movement slows.

*Bones lose density and become more brittle = osteoporosis (As name suggests, bones become porous)

*Joints can stiffen/become painful = arthritis

*Height is gradually lost = posture stoops forward, shrinks

43
Q

Report these signs and symptoms:

A

*Changes in movement and activity

*many report feeling very stiff upon awakening, which sometimes lessens throughout the day-may need frequent rest periods

*Changes in ability to do ROMs

*Pain with movement

*many require around the clock pain patches or analgesics to manage the pain

*New or increased swelling of joints

*White, shiny, red, or warm areas over joints

*Bruising

44
Q

Nervous system:

A

2 main parts:

-central nervous system (CNS)
*part of the nervous system that is composed of the brain and spinal cord. Page 135 in textbook describes the sections.

-peripheral nervous system (PNS)
*part of the nervous system made up of the nerves that extend throughout the body.

45
Q

Nervous system, what it does:

A

*Control and message center of body

*Controls and coordinates all body functions

*Senses information from outside the body – interprets information from the eyes, ears, nose, tongue,

46
Q

Normal changes of aging:

A

*Slower responses and reflexes

*Decrease in sensitivity of nerve endings in skin

*Some memory loss, more often with short-term memory

47
Q

Report these signs and symptoms :

A

*Fatigue or pain with movement

*Shaking or trembling – Parkinson’s residents

*Inability to move one side of body - hemiplegia

*Difficulty speaking or slurring of speech – from various neurological diseases, but mostly due to stroke or CVA

difficult speech, or aphasia – loss of speech

49
Q

dysphagia –

A

difficulty chewing and swallowing

50
Q

The body’s major sense organs are part of the CNS –

A

eyes, ears, nose, tongue and skin

they contain receptors that receive impulses that are relayed to the nerves

51
Q

Normal changes associated with aging:

A

*Reduced vision and hearing – sense of balance may be affected with inner ear problems

*Decreased senses of taste, touch, and smell = decrease in appetite

*Decreased sensitivity to heat, cold, touch = unable to tell water temperature

*All of these types of sensory changes puts the person at greater risk for safety issues with falls, burns etc.

52
Q

Circulatory system:

A

*Made up of heart, blood vessels, and blood

*Blood carries food, oxygen, and essential substances such as hormones to cells.

*A healthy circulatory system is essential for life.

53
Q

Heart has how many chambers? And what are they called.

A

Heart has four chambers: two upper chambers called the left atrium and right atrium, and two lower chambers called ventricles.

54
Q

What is the heart?

A

\The heart is a muscle made up of three layers: pericardium, myocardium, and endocardium.

55
Q

Heart functions in two phases:

A

*contracting phase= systole (ventricles pump blood) and

*resting phase= diastole (chambers fill with blood)

56
Q

Contracting phase=

A

systole (ventricles pump blood) and

57
Q

Resting phase=

A

diastole (chambers fill with blood)

58
Q

Blood Pressure readings are comprised of two numbers:

A

Systolic measurement/Diastolic measurement = for example 120/80

59
Q

Other major functions of circulatory system:

A

*Produces and supply antibodies

*Remove waste products from cells

*Control body temperature

60
Q

Normal changes of aging in the circulatory system:

A

*Heart pumps less efficiently – less oxygen is reaching the body

*Decreased blood flow – again, less oxygen is circulating

*Narrowed blood vessels – more resistance to blood flow = less oxygen is reaching the cells

61
Q

Report these signs and symptoms:

A

*Changes in pulse rate

*Weakness or fatigue – inability to do ADL’s

*Swelling of hands and feet, weight gain

*Pale or blue hands, feet, or lips

*Chest pain

*Shortness of breath, changes in breathing patterns, inability to catch breath

*Severe headache

*Inactivity, which can lead to circulatory problems

62
Q

Respiration

A

the process of inhaling air into the lungs and exhaling air out of the lungs.

63
Q

A full respiration consists of both inspiration + expiration.

Inspiration:

Expiration:

A

Inspiration: the process of breathing into the lungs – brings oxygen into the body

Expiration: the process of breathing out of the lungs – carbon dioxide is sent out of the body

64
Q

Sputum

A

thick mucus coughed up from the lungs.

65
Q

Normal changes of aging:

A

*Loss of lung strength – alveoli sacs have lost elasticity, they do not expand and contract as readily

*Decreased lung capacity – less likely to breath with deep, full breaths (shallow breathing)

*Decreased oxygen in the blood – less deep, full breaths results in less oxygen being drawn into the lungs, slower rate of gas exchange

*Weakened voice – larynx changes, voice can be high pitched

*Increased respiratory rates in the elderly – normal adult range is 12-20 respiration/ minutes – they have higher rates

66
Q

Report these signs and symptoms:

A

67
Q

The Urinary system:

A

Main functions are:

*To eliminate wastes

*To maintain water balance

68
Q

Normal changes of aging in the urinary system:

A

*Reduced ability of kidneys to filter blood

*Bladder holds less urine causing more frequent urination

*(Bladder may not empty completely, causing greater chance of infection

*UTI’s (urinary tract infection) is a very common infection

69
Q

Weakened bladder muscle tone=

A

problems with incontinence

70
Q

urinary incontinence =

A

the inability to control the bladder, which leads to an involuntary loss of urine.

Many older adults take medications known as diuretics, which help the body eliminate fluid.

When a resident takes these meds, they will need to urinate more frequently – thus the need to answer the call light quickly

Residents might be more prone to urinary incontinence while taking these meds, if their bladders fill quickly or overfill.

71
Q

Report these signs and symptoms:

A

*Weight loss or gain - (signals function of this system may be impaired)

*Swelling in extremities, abdomen or bladder area (water retention is not normal)

*Painful urination or burning during urination = infection

*Changes in urine appearance (cloudy, odor, color)

*Change in frequency or amount of urine – more or less

*Complaints that bladder feels full or painful kidney area

*Urinary incontinence

*Inadequate fluid intake

*Confusion – an atypical but common sign of UTI in the elderly

72
Q

The Gastrointestinal System: (GI System):

A

*Digestion
*Peristalsis
*Absorption
*Elimination
*Fecal incontinence
*

73
Q

Digestion:

A

*the process of preparing food physically and chemically so that it can be absorbed into the cells.

*Digestion begins in the mouth with chewing; the body breaks down food into chyme (a semi-liquid substance); then it travels down the digestive tract through the stomach, small intestine, then large intestine then is eliminated from the body through the anus.

*The liver, pancreas, and gallbladder also aid in digestion with juices or enzymes that further breakdown the food.

*Any alteration in the ability to digest food, at any point along the GI tract, causes symptoms of GI dysfunction

74
Q

Peristalsis:

A

involuntary contractions that move food through the gastrointestinal system.

75
Q

Absorption:

A

*the transfer of nutrients from the intestines to the cells.

*The small intestine absorbs most of the nutrients through capillaries

*The large intestine absorbs most of the water from the end product of digestion, or solid waste (feces)

*People unable to normally absorb nutrients from food, usually suffer from weight loss and vitamin deficiencies

76
Q

Elimination:

A

*the process of expelling solid wastes

*waste products of food and fluids that the body has not reabsorbed

77
Q

Fecal Incontinence:

A

the inability to control the bowels, leading to an involuntary passage of stool or feces

78
Q

Normal changes of aging in the gastrointestinal system:

A

*Decreased saliva production = affects chewing/swallowing.

*Dulled sense of taste = may result in poor appetite.

*Absorption of vitamins/minerals decreases.

*Vitamin deficiencies and weight loss

*Digestion takes longer, is less efficient.

*Peristalsis is slower, not as hungry between meals

*Body waste moves more slowly through intestines= constipation

*Elderly also tend to drink insufficient water/fluids = constipation

79
Q

Dysphagia =

A

difficulty swallowing, usually has some neurologic basis, but less saliva adds to the problem

80
Q

Report these signs and symptoms:

A

*Difficulty swallowing or chewing/choking or coughing while eating

*Fecal incontinence

*Diarrhea = loose watery stools

*Weight gain or loss

*Loss of appetite

*Abdominal pain or cramping

*Nausea and vomiting = “coffee ground” appearance to vomit would indicate some form of bleeding

*Constipation – in LTC there is a great deal of emphasis on record keeping of bowel movements

*fecal impaction = is an extreme form of constipation when hard stool cannot be expelled; requires nursing or medical intervention. Textbook: p.305

*Flatulence = passing of gas

*Hiccups, belching = usually from indigestion

*Bloody, or black stools = can be an indication of internal bleeding(black stools are also common when taking iron tabs)

*Poor nutritional intake = record of food/fluid intake is kept

81
Q

Heartburn =

A

burning sensation to stomach region

82
Q

Glands

A

*organs that produce and secrete bio-chemicals called hormones that control various body functions

*The body has 8 major glands

83
Q

Hormones

A

*chemical substances created by the organs that control numerous body functions.

*Every gland produces and secretes one or more hormones

*the primary hormone to focus on is Insulin, which is produced by the Pancreas

84
Q

Insulin =

A

hormone that helps cells use glucose (sugar)

85
Q

Gonads:

A

male (testes) and female(ovaries) sex glands.

86
Q

Hormones are carried in the blood to organs in order to achieve the following:

A

*Maintain homeostasis = master gland = pituitary gland

*Influence growth and development = growth hormone from the pituitary gland

*Regulate blood sugar levels = insulin from the pancreas

*Regulate calcium levels in bones = parathyroid gland

*Regulate body’s ability to reproduce = ovaries produce estrogen and progesterone; testes = testosterone

*Determine how fast cells burn food for energy (metabolism) = thyroid gland hormones

87
Q

Normal changes in the endocrine system:

A

*In general, decrease in levels of hormones – insulin, estrogen, progesterone

*Less able to handle stress – less adrenaline production from the adrenal glands

*this hormone regulates, muscle power, HR, BP, and energy levels during stressful situations

88
Q

Report these signs and symptoms which could be related to dysfunction of various endocrine systems, but are mostly signs and symptoms that could signal Hyper (high) or Hypo (low) blood sugar issues, which are a constant issue with LTC residents.

A

*Headache, dizziness, blurred vision, confusion

*Irritability, sweating, change in normal behavior

*Change in mobility, weakness

*Change in sensation, numbness, tingling

*Weight gain/loss; sweet or fruity breath

*Loss of or/increase in appetite

*Dry skin, skin breakdown

*Hyperactivity – more related to hyperactive thyroid

89
Q

Males -

produce sperm =

produce =

A

Males: testes (located in the scrotum)

sperm: male sex cells

Produce: testosterone; which is needed for the male reproductive organ to function properly

90
Q

Females -

ovaries =

ovaries also produce =

A

Females: ovaries, uterus, fallopian tubes

Ovaries= produce female sex cells (ova)

Ovaries also produce: estrogen and progesterone which are needed for the female reproductive organ to function properly

91
Q

Normal changes of aging in the reproductive system:

Male:

Female:

A

Male:
*Decrease in sperm production

*Decrease in testosterone

*Enlargement of the prostate gland = difficult urination

Female:
*Menstruation ends = menopause, end of reproductive ability

*Decrease in estrogen may lead to loss of calcium, causing brittle bones = osteoporosis

*Drying and thinning of vaginal walls, lubrication decreases, = more prone to vaginal infections

92

Report these signs and symptoms:

A

*Discomfort or difficulty with urination

*Discharge from penis or vagina

*Swelling of genitals

*Blood in urine or stool

*Breast changes, lumps, or discharge

*Reports of painful intercourse

93
Q

The Lymphatic System:

A

*It is closely related to the circulatory system and the immune system

*It has no pump, but is circulated by muscle activity, massage, and breathing = more muscle movement = more lymphatic circulation

94
Q

Functions of the Lymphatic System:

A

*removes excess fluids and waste products

*helps the immune system fight infections.

*lymph fluid, after being purified in the lymph nodes, flows into the bloodstream.

95
Q

Specific immunity

A

a type of immunity that protects against a particular disease that is invading the body at a given time.
-the person already has antibodies in the cells from a previous infection or immunization

96
Q

100
Q

Lymph

A

a clear yellowish fluid that carries disease-fighting cells = lymphocytes.

101
Q

Normal changes in the immune and lymphatic systems:

A

*Weaker immune system = increased risk of infection

*Takes long to recover from an illness
