Elimination Flashcards
What is elimination?
The removal, clearance, or separation of matter. The excretion of waste products.
How do we eliminate?
We eliminate through the skin (sweat), lungs, kidneys, and intestines.
Where is elimination on the Maslow’s Hierarchy of Needs?
Physiological Needs (Air, water, food, shelter, sex, sleep, breathing)
What is the main functional unit of the kidney? How many are there in a human body?
Nephron (If they are not working properly we have problems getting rid of waste and elimination and metabolic problems)
-Each kidney has 1Million of them
-Nephron has 2 parts: blood vessels and renal tubules
What is perfusion and what kinds of problems can it cause for the kidneys?
Blood flow through out the body. Average of 1 L/min to the kidneys and functional nephrons. Hypertension, Diabetes, and other conditions can affect the perfusion of the kidneys.
How does blood move through the kidneys?
Blood flows into your kidney through the renal artery. This large blood vessel branches into smaller and smaller blood vessels until the blood reaches the nephrons. In the nephron, your blood is filtered by the tiny blood vessels of the glomeruli and then flows out of your kidney through the renal vein. Unfiltered blood flows into your kidneys through the renal artery and filtered blood exits through your renal vein. The ureter(small tubes from kidney) carries urine from the kidney to your bladder, and out through the urethra to outside of the body.
*When people have bad stomach pain (kidney stones-jagged) normally are stuck in ureters.
How much urine can our bladder hold?
300-500 ml in adult. Output is measured in ml.
How do we control urine?
There is an internal/external sphincter that help us control the bladder flow. 1. The bladder contracts along with urethral sphincter and pelvic floor muscles relaxes signals micturition center. 2. The micturition center impulses in the brain responds to the urge to void or ignore it (making urination voluntary control). 3. When a person voids, the central nervous system sends a message to the micturition centers , the external sphincters relaxes and empties the bladder.
Anatomy of Stomach
We take in food down the esophagus and it goes down to the stomach (acids/food broken down) and goes into the small intestine (longer small lumen-interior). Absorption is going in small intestine and goes into the large intestine (Pulls water and primary place for stool formation).
What are the parts of the large intestine?
- The tail hanging off of the intestine is the appendix. Starting point of the large intestine is the Cecum, if it goes up it is called the (Ascending colon), if it goes across it is called the (Transverse colon), down is the (Descending colon), then the Sigmoid colon, and finally to the rectum.
If peristalsis is to slow what happens?
Pulling to much fluid out and causes the stool to become hardened and too difficult to pass.
Scope of Elimination
Range of things that can happen with elimination (normal/abnormal)
Physiological changes that affect the overall health condition of elimination
Age- Children are typically 18 to 24 months of age before they are able to identify the urge to urinate and defecate. Toilet training by the parent or caregiver helps the child obtain conscious control of his or her bowel/bladder functions
*Pregnancy can affect elimination patterns because the fetus in the abdominal cavity affects both bowel and bladder function.
* In elderly the reduced tone of the internal and external sphincter as well as reduced neural impulses (reducing the sensation of bowel evacuation) can make the older adult more susceptible to constipation or incontinence.
*Comorbidities
Babies Born
Normally have black stools (meconium)-Sterile stool clears with 2-3 days
* Yellow seedy stool -loose watery-breastfed baby
*diarrhea stool or more formed and brown -formula fed baby
When do toddlers have more control over their bladder/bowel?
*18-24 months
*2-3 years old for bowel control
*If a toddler still couldn’t control their bladder at 30 months would not be concerning because some children development faster than others.
Things that affect elimination
Growth factors, fluid intake, medications, and etc.
Look at Box 46.1 and Page 1278 for Influences on Urinary/Bowel Elimination
Factors that Influence Bowel Elimination: Age, Diet, Fluid Intake, Physical Activity, Psychological Factors, Personal Habits, Position During Defecation, Pain, Pregnancy, and Surgery/Anesthesia
Risk Factors for alterations in Urinary/Bowel Elimination
*Urinary-Age, Impaired Cognition (thinking), Kidney Failure, Impaired mobility, Trauma, Thirsty (people aren’t as thirsty), Females-Short urethra/Males (Retention), Pregnancy (urge to go in beginning/end of pregnancy)
*Bowel-Diet-High bulk fiber/foods/Water(Risks for constipation), Blockage(Impactation), Hemorrhoids, Immobility (Peristalsis slows down), IBS (Stomach problem), Pregnancy (Iron supplement), Debilitated-Can’t get to the bathroom
Kinds of medications that can cause problems with bowel elimination
Opioids (Constipation/Urinary retention), Laxative-Patients can depend on them
Neurological problems can affect bowel elimination how?
People who can’t control or strain down to have a bowel movement.

Physical Assessment Urinary/Bowel Elimination) What is involved?
A focused assessment on urinary/bowel elimination. When was the last time they voided/eliminated? Can you describe it-brown, loose, hard/Color, Clarity, and amount for urine/Any pain and any recent changes
