Week 6 - Elimination and Health Promotion Flashcards
(56 cards)
What organs are included in the gastrointestinal (GI) system?
Mouth, esophagus, stomach, small and large intestines, liver, pancreas, gallbladder, and anus.
What is the primary function of the GI system?
To ingest, digest, absorb nutrients, and eliminate waste.
What is the function of the stomach?
Mixes food and liquids with acid and digestive secretions before emptying into the small intestine.
What are the parts of the small intestine and their function?
Duodenum, jejunum, ileum; absorb nutrients into the bloodstream.
What does the large intestine do?
Absorbs liquid from waste and forms stool for evacuation through the anus.
What is the function of the liver?
Produces bile for fat digestion, synthesizes proteins, breaks down proteins, and stores glycogen.
What role does the gallbladder play?
Stores bile and releases it into the small intestine to help digest fats.
What function does the pancreas serve?
Releases enzymes that help break down fats, proteins, and carbohydrates in the small intestine.
Describe the movement of food through the GI tract.
Mouth → Esophagus → Stomach → Small Intestine → Large Intestine → Rectum → Anus.
What are age-related changes in the GI system?
Peristalsis slows, elasticity diminishes, muscle tone decreases, and medication effects increase.
Which organs make up the genitourinary (GU) system?
Kidneys, ureters, bladder, and urethra.
What is the primary function of the GU system?
Remove waste and excess fluids as urine, regulate electrolytes, blood pressure, and support bone health.
What do the kidneys do?
Filter 120-150 quarts of blood daily to produce urine.
What is the function of the ureters?
Transport urine from the kidneys to the bladder.
Describe the function of the bladder.
Stores urine (up to 2 cups) until it signals the brain to release it.
What does the urethra do?
Carries urine from the bladder to the outside of the body.
How does age affect the GU system?
Decline in kidney function, loss of bladder tone, risk for incontinence, leakage, or retention.
What dietary factors influence urine production and characteristics?
Diet, fluid intake, and beverages like coffee, alcohol, and soda.
What are the steps of abdominal assessment and why in that order?
Inspection, auscultation, percussion, palpation — least to most invasive, to avoid altering bowel sounds.
What do you assess during inspection of the abdomen?
Contour, symmetry, skin color, scars, bruising, lesions, hair distribution, and pulsations.
How do you auscultate the abdomen?
Use the diaphragm for bowel sounds in all 4 quadrants; use the bell for bruits over the aorta.
Describe percussion in abdominal assessment.
Assess tissue density; tympany indicates gas, dullness suggests organs or masses.
What is CVA tenderness and what does it indicate?
Pain at the costovertebral angle; suggests kidney inflammation.
How is palpation performed during abdominal assessment?
Lightly press with fingertips about 1 cm deep, checking for tone, tenderness, masses, or pain.
