Renal Flashcards
What is the glomerulus?
A series of specialized capillary loops
True or false ADH is also known as vasopressin
True
What acts on distal tubule and collecting ducts to increased sodium and water excretion
Prostaglandin E
What is bradykinin?
Small hormone that dilates the afferent arterial and increases capillary membrane permeability to some solutes
The patient has sustained a minor kidney injury. Which structure must remain functional in order for urine to be removed from the blood?
The nephron
Blood flows into ….., and through the specialized capillaries, water and small particles are filtered from the blood to make urine
Glomerulus
Renin is a hormone that helps regulate which functions?
- Bloodflow,
- glomerular filtration rate,
- blood pressure
Which substance increases kidney reabsorption of sodium and water?
Aldosterone
…….. Is a hormone produced in the kidneys parenchyma that stimulates the bone marrow to make red blood cells
Erythropoietin
Which hormone is released from the posterior pituitary and makes the distal convoluted tubule and the collecting duct permeable to water to maximize reabsorption and produce a concentrated urine?
Vasopressin
Based on the knowledge of the normal function of the kidney, which large particles are not found in the urine because they’re too large to filter through the glomerular capillary walls?
- Blood cells
- albumen
- other proteins
What is the average urine output of a healthy adult for a 24 hour period?
1500 to 2000 mL a day
Kidney function, in particular the GFR, is compromised when systolic blood pressure drops below what reading?
70 mm HG
Damage to which renal structure or tissues can change the actual production of urine?
Convoluted tubule’s
The patient has been in my life for several days after motor vehicle accident the nurse encourages ambulation to stimulate the movement of urine through the ureter by what phenomenon?
Peristalsis
Which renal changes associated with aging does the nurse expect an older adult patients report ?
Nocturnal polyuria
An older male patient has a history of an enlarged prostate. The patient is most likely to report which symptom associated with this condition?
Difficulty starting the urine stream
Impairment in the thirst mechanism associated with aging makes an older adult patient more vulnerable to which disorder?
Hypovolemia
The nurses talking to a group of older women about changes in the urinary system related to aging what symptom is likely to be the common concern for this group?
Incontincence
True or false
The most important role of the kidneys are to maintain body fluid volume and composition, and to filter waste products for elimination
True
The kidneys help regulate blood pressure and acid-base balance
True
True or false
The kidneys have a rich blood supply and receive 20 to 25% of the total cardiac output
True
Normal GFR average is 125 mL a minutes
True
GFR is controlled by blood pressure and blood flow
True
