This is a loss of voluntary ability to control fecal and gaseous discharges through the anal sphincter
Bowel Incontinence
Inability to control flatus or minor soiling is called _________
Partial Bowel Incontinence
Inability to control feces of normal consistency is called ____________

Temporary colostomies
This procedure is performed when the rectum or anus is nonfunctional as a result of a birth defect or disease such as cancer of the bowel
Permanent colostomies
This procedure produces a constant liquid fecal drainage. It contains digestive enzymes which are damaging to the skin. Odor is minimal because few bacteria are present
This Colostomy causes the drainage of liquid with digestive enzymes present. There is an increased odor that requires a deodorant to be utilized inside the appliance due to the presence of bacteria
Ascending Colostomy
This procedure causes the removal of malodorous mushy drainage with no control
Transverse Colostomy
This colostomy produces an increasingly solid fecal drainage
Descending Colostomy
After this procedure, stool will be normal and have a formed consistency. Frequency can be regulated. Patient may not have to wear appliance at all times and odors can usually be controlled
During the assessment of a patient with an ostomy, the RN should _____________
nursing history, performing a physical examination of the abdomen, rectum and anus and inspecting the feces for color, consistency, shape, amount, odor and the presence of abnormal constituents
True / False
During the physical exam of a patient with an ostomy, Auscultation should take precedence over palpation?
Auscultation precedes palpation because palpation can alter peristalsis
The primary regulators of fluid and acid-base balance in the body
This hormone is released from the adrenal cortex and causes sodium and water to be reabsorbed in greater quantities which in turn increases blood volume and decreases urine output
This is the reservoir for urine and is the organ of excretion
The wall of the bladder is made up of how many layers?
1 - Inner mucous layer
2 - Connective tissue layer
3 - Three layers of smooth muscle fibers
4 - Outer serous layer
Where is the voiding reflex center located at in the body?
Second to Fourth sacral vertebra
This substance will cause a retention of urinary fluids
These substances will cause an excessive amount of urinary fluids to be excreted from the body
Alcohol and Caffeine
The abnormal production of large amounts of urine is called __________
Excessive fluid intake
Low urine output is called ___________
Oliguria. Usually indicated impaired blood flow to the kidneys or impending renal failure
Oliguria is defined as eliminating < or > __ ml daily or __ ml/hr of urine
< 500 ml a day or 30 ml/hr
Voiding of urine more than usual is also known as
The involuntary urination in children beyond the age of normal bladder control (usually age 4-5)
Painful or difficult voiding possibly caused by a UTI or injury to the bladder and urethra
Urgency to urinate can be caused by _____________
Psychological stress, irritation of the trigone and urethra, poor external sphincter control
Voiding of urine more than twice nightly is also known as _________
This is a symptom, not a disease. It can be caused from stress, sneezing, coughing, laughing and lifting as well as other more serious conditions
Urinary Incontinence
Urinary incontinence that follows a strong sense of urgency is called ______
Urge urinary incontinence
This urinary incontinence occurs at predictable intervals when a specific bladder volume is reached
Reflex urinary incontinence
This urinary incontinence occurs from sneezing, coughing and lifting
Stress urinary incontinence
This type of urinary incontinence occurs involuntary. It is the unpredictable passage of urine
Functional urinary incontinence
This type of urinary incontinence is continuous and occurs at unpredictable times

List the three regions of the kidneys
Renal Cortex
Renal Medulla
Renal Pelvis
This is the functional unit of the kidney and is responsible for making urine
Nephron unit - composed of tubular and vascular structures
Hormone that stimulates the distal tubule to reabsorb Na+ and H2O and excrete K+
Aldosterone - secretion is regulated by the renin-angiotension-aldosterone system
This hormone stimulates the collection duct to reabsorb water as it is released from the posterior pituitary gland in response to low blood volume and increased concentration of solute in the plasma
Antidiuretic Hormone (ADH)
Inhibits the reabsorption of Na+ and H2O causing natriuresis
Atrial natriuretic factor
Stimulates the renal absorption of calcium and the excretion of phosphate
