28
Gastrointestinal System and Older Adults
* Difficulties with chewing and swallowing are generally associated with lack of teeth and diseases * Gastric motility appears to slow modestly, which results in delayed emptying of stomach contents and early satiety (feeling of fullness) * Dysphagia increases * Constipation common
29
Genitourinary System and Older Adults
* Urinary retention; irritative voiding symptoms including frequency, feeling of incomplete bladder emptying, multiple nighttime voiding * Male: Benign prostatic hyperplasia * Female: Relaxed perineal muscles; detrusor instability leads to urge incontinence; urethral dysfunction (stress urinary incontinence)

33
Pathological Aging: AD
* Forgetfulness is manifested in many daily actions; patients may lose their ability to recognize familiar faces, places, and objects and they may become lost in a familiar environment. * Primary goal is to help maintain mental function as well as manage the cognitive and behavioral symptoms, and slow down the symptoms of the disease. * Promoting the patient’s physical safety, promoting independence in self-care activities, reducing anxiety and agitation, improving communication, providing for socialization and intimacy, promoting adequate nutrition, promoting balanced activity and rest, and supporting and educating family caregivers.

38
Metabolic Panel
Measures 14 different substances in your blood Provides important information about your body's chemical balance and metabolism * glucose, calcium, total protein, bilirubin, BUN, creatinine, albumin, sodium, potassium, bicarb, chloride, ALP, ALT, AST
39
Renal Functioning Labs
H+ Ions: in renal failure will be high or low * increase: metabolic acidosis * decrease: metabolic alkalosis Urea/BUN: biproduct of protein waste * Normal: 10-20 * Elevated: dehydration Creatinine: waste product from muscles * Elevated over 1.3: can clog kidneys - kidney impairment Urine Specific Gravity * 1.003-1.030 Urine less than 30mL/hr - bad kidneys
40
Liver Functioning Labs
* Alanine transaminase (ALT). ALT is an enzyme found in the liver that helps convert proteins into energy for the liver cells. When the liver is damaged, ALT is released into the bloodstream and levels increase. * Aspartate transaminase (AST). AST is an enzyme that helps metabolize amino acids. Like ALT, AST is normally present in blood at low levels. An increase in AST levels may indicate liver damage, disease or muscle damage. * Alkaline phosphatase (ALP). ALP is an enzyme found in the liver and bone and is important for breaking down proteins. Higher-than-normal levels of ALP may indicate liver damage or disease, such as a blocked bile duct, or certain bone diseases. * Albumin and total protein. Albumin is one of several proteins made in the liver. Your body needs these proteins to fight infections and to perform other functions. Lower-than-normal levels of albumin and total protein may indicate liver damage or disease. * Bilirubin. Bilirubin is a substance produced during the normal breakdown of red blood cells. Bilirubin passes through the liver and is excreted in stool. Elevated levels of bilirubin (jaundice) might indicate liver damage or disease or certain types of anemia. * Prothrombin time (PT). PT is the time it takes your blood to clot. Increased PT may indicate liver damage but can also be elevated if you're taking certain blood-thinning drugs, such as warfarin.
41
Coag Labs
Coagulation tests measure your blood's ability to clot, and how long it takes to clot. * APTT (activated partial thromboplastin time) – measures one part of the clotting pathway known as the “intrinsic pathway” * INR (international normalised ratio) – measures one part of the clotting pathway known as the “extrinsic pathway” * Fibrinogen – this protein is a precursor to fibrin, which is an essential part of a blood clot.
42
Glucose Test
Measures the glucose levels in your blood * High: possible diabetess, hyperthyroidism, pancreas disorder, stress from surgery or trauma * Low: liver disease, kidney disease, hypothyroidism, alcohol use disorder
43
Lipid Panel
* Total cholesterol: This is your overall cholesterol level — the combination of LDL-C, VLDL-C and HDL-C. * Low-density lipoprotein (LDL) cholesterol: This is the type of cholesterol that’s known as “bad cholesterol.” It can collect in your blood vessels and increase your risk of cardiovascular disease. * Very low-density lipoprotein (VLDL) cholesterol: This is a type of cholesterol that’s usually present in very low amounts when the blood sample is a fasting samples since it’s mostly comes from food you’ve recently eaten. An increase in this type of cholesterol in a fasting sample may be a sign of abnormal lipid metabolism. * High-density lipoprotein (HDL) cholesterol: This is the type of cholesterol that’s known as “good cholesterol.” It helps decrease the buildup of LDL in your blood vessels. * Triglycerides: This is a type of fat from the food we eat. Excess amounts of triglycerides in your blood are associated with cardiovascular disease and pancreatic inflammation.
44
Urine Specific Gravity
Measures the density of urine compared to water. It is a measure of the concentration of solutes in the urine. Assesses kidneys ability to excrete water * Normal: 1.005-1.030
45
Homeostatic Mechanisms: Kidneys
Major functions in order to maintain fluid balance * Regulation of ECF volume and osmolality by selective retention and excretion of body fluids * Regulates electrolytes and pH * Excretion of metabolic wastes and toxic substances
46
Homeostatic Mechanisms: Heart
The pumping action of the heart circulates blood through the kidneys under sufficient pressure to allow for urine formation.
47
Homeostatic Mechanisms: Lungs
Exhalation: removes 300mL of water daily (insensible water loss) * Decrease breathing rate = more CO2, more acidic * Increase breathing rate = less CO2, less acidic
48
Homeostatic Mechanisms: Pituitary
Hypothalamus makes ADH – stored in posterior pituitary and released as needed to conserve water * ADH - secreted when dehydration or blood loss is present
49
Homeostatic Mechanisms: Adrenal
Cortisol secreted produces sodium and fluid retention Aldosterone secreted by zona glomerulosa * Increased secretion: sodium retention, potassium loss * Decreased: sodium loss, potassium retention
50
Homeostatic Mechanisms: Baroreceptors
Respond to changes in blood volume and regulate symp and parapsymp activity * Decrease in impulses stim SNS -> stim SA node * Increase HR, conduction, and contractility * Constricts renal arterioles, triggers renin release and stim of RAAS system
51
Homeostatic Mechanisms: RAAS
Kidney's sense low profusion -> secrete renin II stim adrenal gland to secrete aldosterone -> increases Na and water reabsorption at nephron * raises blood volume and BP
52
HM: Antidiuretic Hormone and Thirst
As serum concentration or osmolality increases or blood volume decreases, neurons in the hypothalamus are stimulated by intracellular dehydration; thirst then occurs, and the person increases their intake of oral fluids.
53
HM: Osmoreceptors
Osmotic pressure increases -> neurons become dehydrated and release impulses to posterior pituitary to release ADH * This causes reabsorption of water and decreased urine output
54
HM: Natriuretic Peptide
Affect fluid volume and cardiovascular function through natriuresis (the excretion of sodium), direct vasodilation, and the opposition of the renin–angiotensin–aldosterone system.
55
Hypovolemia
Patho * Loss of ECF volume exceeds the intake of fluid Causes * abnormal fluid losses from vomiting, diarrhea, GI suctioning, and sweating * decreased fluid intake * DI * adrrenal insufficiency * osmotic diuresus * hemorrhage * coma Assessment * HIGH: H&H, serum and urine osmolality and specific gravity, BUN and creatinine (greater than 20:1), urine specific gravity and osmolarity * LOW: low urine sodium S/S * weight loss, decreased skin turgor, oligouria, conc urine, low BP, flattened neck veins, thirst, confusion, high pulse, muscle cramps, high temp, cool/clammy/pale skin Prevention: Identifies patients at risk and takes measures to minimize fluid losses NM * I&Os every 8 hrs, or hourly * skin and tongue monitored - longitudinal furrows * mental functioning - decreasing cerebral perfusion * oral fluids, oral rehydration solutions
56
Hypervolemia
Patho * Simple fluid overload or diminished function of the homeostatic mechanisms Causes * heart failure * kidney dysfunction, cirrhosis, excessive salt S/S * Edema, distended jugular veins, and crackles (abnormal lung sounds due to interstitial pulmonary fluid) * high BP, high RR, high urine output Assessment * LOW H&H, serum and urine osmolality, urine sodium and specific gravity, BUN Prevention: sodium-restricted diets NM * diuretics * restrict sodium * may have increased protein intake * I&Os, weighed daily * restore intravascular volume
57
Hyponatremia
Patho * less than 135 * imbalance of water S/S * Poor skin turgor, dry mucosa, headache, decreased saliva production, orthostatic fall in blood pressure, nausea, vomiting, and abdominal cramping * Neurologic changes, including altered mental status, status epilepticus, and coma, are related to the cellular swelling and cerebral edema * Anorexia, muscle cramps, and a feeling of exhaustion Assessment * serum osmolality decreased * Lack of Na ingestion: urinary Na content = less than 20 and specific gravity is low - 1.002 to 1.004 * SIADH: urinary sodium content is greater than 20 mEq/L, urine specific gravity is usually greater than 1.012 NM * sodium replacement * water restriction * monitor I&Os
58
Hypernatremia
Patho * more than 145 * Caused by a gain of sodium in excess of water or by a loss of water in excess of sodium. Causes * DI: can lead to lack of adequate reabsorption of water into the bloodstream * heatstroke * nonfatal drowning in seawater S/S * Skin: flushed, edema, low grade fever * excess thirst * dry tongue * N/V * increased muscle tone Assessment * Serum osmolality exceeds 300 mOsm/kg (300 mmol/L) * The urine specific gravity and urine osmolality are increased as the kidneys attempt to conserve water NM * hypotonic solutions * Observing for changes in neurologic status, such as confusion, disorientation, and possible decreased level of consciousness * Don’t want rapid reduction – could cause cerebral edema
