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
ADH increases tubular permeability to water, allowing water to leave the tube and be reabsorbed in the capillaries
True
During watery absorption, the membrane of the distal convoluted tubule is more permeable to water due to the influence of ADH
True
The nurses taking a history on a 55-year-old patient denies any serious chronic health problems. With sudden onset sign or symptom suggests possible kidney disease in a patient
Hypertension
Which patient narrative describes the symptom of dysuria?
It burns when I pee
The nurse and nutritionist are evaluating the diet and nutritional therapies for patient with kidney problems. Blood urea nitrogen levels for this patient are tracked because of the direct relationship to the intake and metabolism of which substance?
Protein
The nurses taking a history of a patient with a change and urinary patterns. In addition to the medical and surgical history, what is the nurse application about to complete the assessment?
- Occupational exposure to toxins
- Use of illicit substances such as cocaine
- Potential exposure to sexually-transmitted disease
The nurse is determining whether patient has a history of hypertension because of the potential for kidney problems. Which question is best to illicit this information?
Have you ever been told that your blood pressure was high
Patient appears very uncomfortable with the nurses questions about your night functions and patterns. What is the best technique for the nurse to use to elicit relevant information and decrease the patients discomfort?
Use the patients own terminology
The nurses taking a nutritional history on a patient. The patient states I really don’t drink as much water as I should what is the nurses that’s response?
What would encourage you to drink the recommended 3 L per day
When patients having problems with the kidneys or urinary tract, what is common symptom the prompt them to seek medical attention?
Pain in the flank or abdomen or pain when urinating
Which ethnic group have the highest risk for end-stage kidney disease secondary to diabetes mellitus and hypertension?
African Americans
Which over-the-counter product use that patient is a nurse explore further the potential impact on kidney function?
NSAIDs
The nurses performing assessment of the renal system. What is the first step in the assessment process?
Observe the flank region for asymmetry or discoloration
The patient has anorexia, nausea and vomiting, muscle cramping, and pruritus. How does the nurse interpret these findings?
Uremia
The nurse is auscultating the renal artery and here’s the bruit. What does this finding indicates?
Renal artery stenosis
The patient is diagnosed with renal artery stenosis. Which sound does the nurse expect to hear by auscultation when a bruit is present in renal artery?
Swishing sound
