WEEK 7 Flashcards
what is the urinary tract’s primary function?
convert and remove excess waste and fluids from the body in the form of urine.
what does the urinary tract also do when a person is healthy?
regulates levels of electrolytes and the production of red blood cells, produces hormones that are important for blood pressure regulation, and helps to keep bones strong
how does urine travel?
through the urinary system which is:
kidneys, ureters, bladder, and urethra
first stop of the urinary tract?
kidneys
two bean-shaped organs located below the ribcage, each adjacent to the spine
how many quarts of blood can kidneys filter daily?
120 to 150 quarts
what do kidneys also do?
convert waste products and excess fluid into urine to be removed from the body.
During this process, approximately 1 to 2 quarts of urine is produced each day. From the kidneys, urine is transported to the bladder by ureters, which are thin tubes of muscle. There is one ureter from each kidney.
how many ureter for EACH kidney
one for each
3rd stop in the urinary tract?
bladder
a hollow ballon-shaped muscle
what does the bladder do?
begins to fill and stretches to accommodate the urine, holding up to two cups.
how much can the bladder hold up to?
2 cups
urine filling: bladder
During urine filling, the bladder muscles remain relaxed. Once the bladder reaches capacity, receptors inside the bladder send signals to the brain to let the client know it is time to empty the reservoir.
what is the amount of produced determined by?
kidney function
urination
Once the bladder has filled, the body releases the urine through the urethra and out of the body,
second stop in urinary tract
ureter
final stop of urinary tract
urethra
muscles that work together to prevent accidental urination
The first muscle, the urethra, connects to the bladder at the bladder neck. The bladder neck consists of an internal sphincter (the second muscle), which holds urine inside the bladder. The last set of muscles, known as the pelvic floor muscles, along with the external sphincter, helps to support the urethra.
brown urine can mean?
dehydration
kidney or liver issues
red tint urine can mean?
blood in the urine
what is considered effective urine production?
in adults, 1.5-1.8 liters daily
what does expected urine production do as you age?
decrease
how much urine does infants produce?
2 mL/kg/hr
how much urine does toddlers produce?
1.5 mL/kg/hr
how much urine do teens produce?
1 mL/kg/hr
how much urine do adults produce?
0.5 mL/kg/hr
why is observing the amount and characteristics of urine is an important assessment skill?
deviations from the norm may suggest other health issues such as dehydration or kidney dysfunction.
what can drinking a larger amount of fluid may result in
more urine volume and a clearer color as well as little odor
what food makes urine appear red so that you make think its blood?
blackberries, beets, and rhubarb may turn urine a reddish color
what can dark brown urine mean with regards to doo>
eating aloe or fava beans
what food can increase odor of urine
asparagus
what does the digestive system consist of?
liver, pancreas, gallbladder, and a series of hollow organs that originate at the mouth and terminate at the anus. These organs, which include the mouth, esophagus, stomach, small and large intestines, and anus, make up the gastrointestinal (GI) tract.
peristalsis
Contractions that occur throughout the digestive system that move food along a pathway to be digested.
define digestion
Food and liquid enter the body at the mouth. Once chewing begins, food is broken down and pushed into the throat and swallowed. A small flap of cartilage, called the epiglottis, prevents food and liquid from entering the airway, but allows them to continue into the esophagus. In the esophagus, the process called peristalsis continues to move food along a pathway to be digested. Once in the stomach, food and liquid are mixed with digestive secretions before slowly being emptied into the small intestine.
what happens in the small intensine?
In the small intestine, food and liquid continue to mix with digestive secretions from the pancreas, liver, and small intestine as peristalsis continues to aid in the transport of food to the large intestine. During this time, digested nutrients are absorbed by the intestinal walls and enter into the bloodstream, where they are transported to other tissues for use by the body.
order in which food or liquid contents are transported through the gastrointestinal tract?
mouth
esophagus
stomach
small intestine
large intestine
anus
Bristol Stool Chart
constipation (types 1 and 2), to expected or ideal stools (types 3 and 4), to diarrhea (types 5 to 7).
what foods can increase risk of diarrhea?
Alcohol
Caffeinated beverages and foods
Dairy (milk, cheese, cream, and ice cream)
Foods that are high in fat or are highly greasy
Beverages that contain fructose
Spicy foods
Apples, peaches, and pears
Products that contain sweeteners, such as sorbitol, mannitol, xylitol, and maltitol
what should urine be?
clear (not cloudy), light yellow in color, and odorless
stress incontinence
Coughing, sneezing, laughing, or physical activity that increases pressure on the bladder, resulting in urine leakage.
urge incontinence
A strong need or urge to urinate, but leaking occurs before the client gets to the toilet.
reflex incontinence
Urinary leakage as a result of nerve damage.
overflow incontinence
Incomplete bladder emptying that results in the bladder overfilling when full, leading to urine leakage.
functional incontinence
Physical inability to reach the toilet in time. This may be due to a physical impairment such as being wheelchair bound or having arthritis of the hands, which can hinder the fine motor skills needed to unbutton clothing.
nocturnal enuresis
(nighttime bedwetting): Common in children but may occur in adults who have consumed too much alcohol, who consume caffeine at night, or who take certain medications.
urinary retention
Incomplete emptying of the bladder.
