A partially emptied bladder
What do secretions allow?
Allows the nephrons to add to the filtrate substances the body does not need, which now looks like urine
How is creatine measured?
As an indicator of kidney function
Urinary incontinence is caused by what?
By poor muscle tone, poor blood circulation, damaged bladder or urethra, urinary tract infection, confusion, neurological changes, and some medications
What do alpha-adrenergic blockers do?
Block receptors in the smooth muscle of the bladder and prostate, causing them to relax
Fluid in the body is distributed into what three compartments?
Blood (5 percent), between cells (15-30 percent), and inside cells (50-60 percent)
What do the kidney's control and how?
Blood pressure by adjusting the amount of fluid excreted into the urine
What are the treatments for BPH?
Can be relieved with medication, but surgery is often needed
What should the medication aide must be alert on?
Changes in urination, urine pattern, or the resident's ability to urinate
What do cholinergic cause?
Contractions of the bladder to relieve urinary retention
What are some of the other methods of excretion?
Diarrhea, vomiting, difficulty breathing or excessive sweating, there is often a change in urination that should be reported
What are the warning signs for dehydration?
Dry mouth, cracked lips, sunken eyes, and dark urine
The kidneys actively reabsorb what substances?
Glucose, water, and electrolytes
Where are the kidneys located?
Each side of the spinal column just above the waist
What are the causes of dehydration?
Excessive vomiting, diarrhea, or pyloric (stomach) obstruction
What are the symptoms of renal failure?
Fatigue, weakness, edema, cough, difficulty breathing, excessive urination, confusion, and decreased level of consciousness
What urethra is shorter, male or female?
Female (it's about 3 cm long)
What are the factors increasing risks of UTI?
Female, urinary stasis: stagnation or normal urine flow, sexual activity, catheterization, and institutionalization: living in a facility
What do nephrons do?
Filter waste products from the blood
What are the three processes that the urine formation occurs through?
Filtration, reabsorption, and secretion
What are the side effects of diuretics?
Fluid and electrolyte imbalance, potassium depletion, dehydration, weakness, lethargy, and low blood pressure
Where is the control for emptying your bladder?
In the brain, which tells the bladder sphincters to relax, allowing the bladder to empty
What do diuretics do?
Increase urine excretion; they work on different chemicals and parts of the nephron
What are the causes of edema?
Increased permeability of capillaries where excess fluid leaks out into the tissues (may include burns, deficiencies in vitamins B and C, and heart or kidney disease)
What is urinary tract infection (UTI)?
Infection of one or more structures in the urinary system
What can incontinence lead to?
Infection, skin breakdown and emotional upsets
How do kidney's work?
Kidney's work as an overflow mechanism to maintain optimal fluid balance
Most of the liquid portion of the blood is filtered through where?
Kidneys
What do the ureters lead from?
Lead from each kidney to the bladder and transport urine from the kidneys into the bladder
What can BPH lead to?
Lead to urethral obstruction, blocking the flow of urine
What do minerals do?
Maintaining proper fluid balance in the body (such as sodium and potassium)
What urethra is longer, male or female?
Male (it's about 20 cm long and passes through the donut-shaped prostate gland)
What are the treatments for urinary incontinence?
Medications, bladder retraining programs, fluids, and/or surgery
What gender is more common to have a BPH?
Men (over the age of 50)
When does reabsorption occur?
Occurs as the filtrate passes through the nephron
What are the symptoms of UTI?
Odor, cloudy urine, incontinence, frequency, chills, and burning, pain with urination
What do each kidneys contain?
One million nephrons
What do antiandrogens do?
Reduce the size of the prostate; can cause fetal damage if handled by pregnant women
What do antispasmodics/anticholinergics do?
Reduce the strength of bladder contractions and increase bladder capacity
What do the kidney's do?
Regulate fluid and electrolyte balance, blood pressure, and pH, and remove waste products such as ammonia and creatinine
What do beta blockers do?
Relax muscles of the bladder and reduce the number of contractions
What do analgesics do?
Relive pain or burning associated with an infection of the bladder
What should the medication aide do if they notice changes in urination, urine patter, or the resident's ability to urinate?
Report any changes to the person providing direction and monitoring
Electrolytes are often what?
Salt compounds
What are the side effects of antibiotics?
Stomach distress, drowsiness, dizziness, rash, allergic reactions, diarrhea, photosensitivity, nausea, and vomiting
What does the bladder act as?
Storage bag for urine
What is edema?
The expansion of fluid between the cells
What happens when a bladder infection is left untreated?
The infection can travel up to the kidney, causing a kidney infection
What is urinary incontinence?
The involuntary passing of urine out of the body
What are the age-related changes?
The kidneys reduce in size and weight, working nephrons decrease, decrease in blood flow also decreases filtering efficiency, loss of muscle tone in the bladder, and pelvic muscles makes it more difficult to hold large amounts of urine in the bladder
What is filtrate?
The liquid in the kidneys
Where does blood passes through?
The nephrons via filtration with blood pressure as the force
Who is more likely to receive a UTI, female or male?
Women are more likely to get bladder infections because the female urethra is shorter and close to the vagina and rectum
What do antibiotics do?
Treat infection; nausea, vomiting, and diarrhea are common side effects
What does the urinary system consists of?
Two kidneys, two ureters, a bladder and a urethra
Where does urine leave the body through?
Urethra

Urinary frequency, dribbling, UTIs, nocturia - urination at night, Dysuria - painful urination, interference with urine flow, and erectile dysfunction
The kidneys refuse to reabsorb what harmful substances?
Waste products of metabolism
What do antigout drugs do?
Work on the kidney by promoting excretion of the waste product uric acid (gout is a buildup of uric acid in a joint that causes severe pain, warmth, redness, and swelling)
What can be life-threatening for a bladder infection?
When the infection travels up into the blood, causing a blood infection (sepsis)
When does filtration occur?
When there is the movement of a substance from a high concentration area to a low concentration area, aided by a force
