Psychomotor Learning vs. Affective learning
 
learning a skill that requires both mental and physical activity
involves changes in feelings, beliefs, attitudes, and values.
Factors affecting patient learning

Motivation-How can we motivate learning? Create a warm environment, convey interest in the patient. Remember they are motivated to learn only if they believe health is important.

Readiness-physical and emotional ability to learn: not before treatments, tests, or while in pain.
Timing- present items that can be used immediately; need time to absorb and apply the information given.
Factors affecting patient learning
Active Involvement- learners retain 10% of what they read, but 90% of what they do.
Feedback- positive feedback encourages the learner to continue in the educational process. Sometimes they need encouragement. Never use anger, punishment, ridicule, etc.
Repetition-each time you repeat the information the learner retains more.
Factors affecting patient learning

-Environment-Private, quiet, physically, and psychologically comfortable.

Scheduling the session- plan for uninterrrupted time

Amount & Complexity of Content- the more complex and detailed the content the more difficult it is to learn and retain.

Factors affecting patient learning
Communication-Verbal and non-verbal. Several factors including culture, language barriers, and distraction play an important role.
Special Populations-. learning disabilities: plan accordingly
Developmental Stage-12 common in children. Assess their level of development
Factors affecting patient learning
Cultural Factors- be aware of values, social structure, etc. of culture you are teaching to.
Literacy- about 20% of adults in the US cannot read and write at a level considered necessary for functioning in everyday life.

-Alterations in urinary elimination may affect all body systems
 
Micturition
1.Desire to urinate
Bacteriuria
 
2.Presence of bacteria in the urine
Urinary retention
3.lack of ability to urinate (BPH)
Residual urine
4.Residual urine is urine left in the bladder after a person has urinated (breeding for uti)
Urgency
5.sudden, compelling urge to urinate.
Dysuria
6.painful urination
Urosepsis
7.Sepsis from obstruction of infected urine
Proteinuria
8.means the presence of an excess of serum proteins in the urine
Anuria
 
1.absent production of urine
Enuresis
2.Bed-wetting
Hematuria
3.Presence of blood in the urine
Incontinence
4.involuntary excretion of urine: urge, stress (cough, sneeze), overflow, functional (mobility), transient (UTI), reflex (no urge to void but bladder is full).
Oliguria
5.Decreased production of urine
Polyuria
6.condition characterized by the passage of large volumes of urine
Nocturia
7.need to get up during the night in order to urinate, thus interrupting sleep.
Urinary diversion
8.Surgical created opening for urinary elimination.
Urinary elim: Ileal Conduit
 

Most common. Small piece of ileum removed and brought out through the abdominal wall creating a stoma. Urine and mucus from the ileum drain continuously. Mucous membrane protects the kidneys from ascending infection.

Continent Urostomy
 

Kock pouch: variation of ileal conduit. Urine drains from the ureters into a surgically created pouch. Stoma that is created contains a nipple valve to keep urine from leaking. Patient inserts a catheter into the stoma to drain the urine.

Factors affecting urinary elimination
 
Growth & Development- Increase in bladder size
Sociocultural factors- Assistance from same gender
Psychological factors- Loss of dignity
Personal habits- Putting off voiding
Muscle tone-After having a baby
Factors affecting urinary elimination continued

Fluid intake- Increase intake = increase output, caffeine, alcohol. Physical activity

Urinary elim Diagnostic studies: Cystoscopy
 
1.Cystoscopy is a test that allows your doctor to look at the inside of the bladder and the urethra using a thin, lighted instrument called a cystoscope
Urinary elim Diagnostic Studies: IVP
An intravenous pyelogram (IVP) is an X-ray test that provides pictures of the kidneys, the bladder, the ureters, and the urethra (urinary tract) During IVP, a dye called contrast material is injected into a vein in your arm. it travels through the blood stream and collects in the kidneys and urinary tract, turning these areas bright white. An IVP allows the radiologist to view and assess the anatomy and function of the kidneys and lower urinary tract.
Urinary elim Diagnostic Studies:  Retrograde Pyelography
  A retrograde pyelogram is a type of x-ray that allows visualization of the bladder, ureters, and renal pelvis. Generally, this test is performed during a procedure called cystoscopy - evaluation of the bladder with an endoscope (a long, flexible lighted tube). During a cystoscopy, contrast dye, which helps enhance the x-ray images, can be introduced into the ureters via a catheter.
Urinary elim Diagnostic Studies:  Ultrasonography
 
1.Pelvic ultrasound, bladder ultrasound, etc.
Urinary elim Lab Studies:
 
Routine urinalysis

Clean catch urine- Cleanse genitalia before voiding and collect the sample midstream so it will be free of organisms from the urethral meatus or distal urethra.

Sterile specimenindwelling catheter

24 hour urine collectionVoid record time, discard first voiding and collect all the urine for the next 24 hours. (post signs, ice, etc)

Kidney function studies- Blood tests: assess renal function and hydration.  Creatinine ,Creatinine clearance, BUN
Urinary elim Possible nursing diagnosis
 
Altered urinary elimination r/t frequency, urgency, aeb urinating in small amounts often, constant sensation of full bladder.
Urinary elim Planning Goals: Short term (example)
Patient will urinate 100-200ccs at a time within 48 hours.
Urinary elim. Planning Goals: Long term (Example)
Patient will return to usual voiding pattern without discomfort within one week.
Possible Implementations for Urinary elim.
Assess intake & output, record.
Assess urinary voiding pattern.
Assess discomfort during urination.
Assess for bladder distention, urinary retention.
Administer antibiotics as ordered.
Encourage increased fluid intake.
Strengthen muscle tone (Kegel exercises )
Purpose of G.I. tract
 
Prepare food products for use by the body’s cells,

Promote the absorption of fluid and nutrients,

Eliminate wastes.
Peristalsis
the rhythmic contraction of smooth muscles to propel contents through the digestive tract.
Flatus
presence of a mixture of gases produced during digestion
Feces
waste product from the digestive tract expelled through the anus
Defecation
the Act or process by which organisms eliminate solid or semisolid waste material (feces) from the digestive tract via the anus.
Valsalva Maneuver
Increase the pressure to expel the feces by contracting the abdominal muscles while maintaining a closed airway.
Fecal impaction
a solid, immobile bulk of stool that can develop in the rectum as a result of chronic constipation
Anorexia
is the decreased sensation of appetite
Mastication/chewing
is the process by which food is mashed and crushed by teeth.
Factors affecting Bowel elimination
Age- Meconium to toilet training and problems again in the elderly.-loss of tonus smooth muscle of colon
Diet- Eating at regular time promotes a regular pattern. High fiber, yogurt help while calcium and carbs may not.
Pregnancy- Increase progesterone slows peristalsis plus effect of growing uterus.
Fluid intake- Low intake slows peristalisi and leads to dry hard stools
Factors affecting Bowel elimination
Pain- From hemmorhoids
Medications- Iron antacids pain meds and antimotility drugs may cause constipatin while antibotics and laxatives will cause diarrhea. NSAID irritate the stomach.
Surgery or Anesthesia- Anesthesia slows motility. Bowel surgery may lead to paralytic ileus. Usually have NG tube inserted to suction secretions until peristalisis returns (decreases bloating and discomfort).
Factors affecting bowel elimination
Pathologic Conditions- food allergies, diverticulosis (saclike outpuchings of the mucosa through muscle layers. Diverticulitis when these outpouchings become infected.
Psychological Factors- Diet, work (avoiding using the bathroom)
Personal habits-
Activity- Decreased movement slows peristalsis.
Position- Privacy
Diagnostic tests: Colonoscopy
The doctor puts a thin tube that has a light through the rectum and into the colon. This allows the doctor to "see" the lining of the whole colon.
Diagnostic tests: Flexible sigmoidoscopy
The doctor puts a thin tube that has a light into the rectum. It allows the doctor to check the rectum and the lower part of the colon.
Diagnostic tests: Upper endoscopy
This is more accurate than a barium swallow radiograph and may be performed in a hospital or a doctor's office. The doctor sprays the throat to numb it and then slides a thin, flexible plastic tube called an endoscope down the throat. A tiny camera in the endoscope allows the doctor to see the surface of the esophagus and to search for abnormalities. The doctor may use tiny tweezers (forceps) in the endoscope to remove a small piece of tissue for biopsy.
Diagnostic tests: Barium Enema
The doctor injects fluid containing a substance called barium into the rectum. Barium allows the doctor to see the colon on an X-ray.
Diagnostic tests:

Means of Regulating Fluid Balance
Kidneys *
Endocrine system
Cardiovascular system
Lungs*
GI system

*systems that will be our focus
Maintaining Homeostasis
Lungs
  • exhalation (exchange of gases)
Kidneys
  • regulation of ECF by retention/excretion of fluids and electrolytes (Na+ and K+)
  • regulation of pH by retention/excretion of H+ ions
  • excretion of wastes
Heart and blood vessels
  • pumping action

Examples of Kidneys Acting to Maintain Homeostasis (all temporary)
Hypothalamus (sensing thirst/activated by increase in serum osmolarity ) releases ADH (anti-diruretic hormone) which acts on the kidneys (retain more water/go to the bathroom less)

Adrenal cortex (increase response to increase levels of K+) release Aldosterone, which acts on kidney tubules to recycle Na+ (which recoups H20)

Adrenal gland (in response to hypovolemia or low BP) releases RENIN, which in then converted into Angioteninogen then into Angiotensin I and then Angiotensin II which increases
Examples of Kidneys Acting to Maintain Homeostasis (all temporary) CONTINUED
Adrenal gland (in response to hypovolemia or low BP) releases RENIN, which is then converted into Angioteninogen then into Angiotensin I and the Angiotensin II which increase Na+ reabsorption (via Aldosterone), water retention by the kidneys, salt appepite/water intake, increased BP, and the release of ADH
Daily Fluid Gains
Metabolism - 250-300 ml
Oral fluids - 1100-1400 ml

Skin - 500-600 ml
Lungs - 400 ml
GI Tract - 100-200 ml (3-6 l are reabsorbed)
Additional loses - wounds, external bleeding, third space loss


Insensible Fluid Loss

Sensible Fluid Loss
The loss of both water and electrolytes
Disorders of Fluid Balance
HYPOVOLEMIA

  • caused by abnormal skin, GI, renal losses, bleeding, decreased intake, movement of fluid to third space
  • signs/symptoms - weakness, fatigue, syncope, confusion, oliguria, low BP, weight loss, tachycardia, sunken eyeballs
Disorder of Fluid Balance
HYPERVOLEMIA
expansion of the ECF volume, increase amount of intravascular fluid
cases are chronic stimulus of kidneys or abnormal kidney function to conserve Na+ and water, excessive IV fluids, interstitial to plasma fluid shift
signs/symptoms - edema, weight gain, increased BP, bounding pulses, SOB, rales, tachypnea, distended neck, veins, ascites
Fluid Volume Deficits
Fluids and electrolytes lost in proportion
(ratio of H2O/electrolytes remains the same)

Non-dehydration
Causes are fistulas, GI suctioning, Third Space shifts, Anorexia, inability to obtain fluids
Dehydration
Excessive, repaid loss of H2O from body tissues
Results in disturbance of Na+, K+, and Cl- balance

Causes - prolonged fever, diarrhea, vomitting
Arterial pH
Indirect measurement of hydrogen ion (H+) concentration

Normal values - range between 7.35 - 7.45

Below 7.35 - Acidosis
Above 7.45 - Alkalosis

Maintaining pH
pH is maintained by utilization of a buffer

Buffer - a substance that can absorb or release H+ to correct an acid/base imbalance

examples: HCO-3 (bicarbonate), Phosphate (PO3), Ammonium, Protein, CO2
Acid Base Balance
Acid base balance is based upon H+ concentration

Increased H+ --> decreased pH/Acidosis
Decreased H+ --> increased pH/Alkalosis
Lungs/Kidneys - Buffer Systems
Lungs - eliminate/retain CO2 in direct relation to arterial pH

Kidneys - increase/decrease HCO-3 concentration in body fluids


Acid Base Imbalances/ABG's (just the ones we need to know)
pH - 7.35-7.45

PaCO2 - 35-45mm

HCO-3 - 22-26 mEq/L
Arterial Blood Gases/Lab Values
If pH is outside the parameter of 7.35-7.45, then ABC is labeled UNCOMPENSATED

If pH is within the parameter of 7.35-7.45 (and other values are outside the range), then the ABG is labeled as COMPENSATED

If all parameters are within their specified range, the ABG is labeled as NORMAL
Uncompensated ABG
Value is OUTSIDE the range
Lower than 7.35 = Acidosis
Higher than 7.45 = Alkalosis
Respiratory Acidosis
Increased PaCO2
Decreased pH (increased H+)
Respiratory depression leads to hypoxemia (COPD)
Respiratory Alkalosis
Decreased PaCO2
Increased pH (decreased H+)
Seen in anxiety with hyperventilation and initial phase of asthma attack
