Test #4 Slide Questions Flashcards
What is the function of the kidneys?
They filter the blood to remove waste products and maintain normal hydration status
What are the main organs of the urinary system?
Kidneys, ureters, bladder, and urethra
What physiological part of the kidney has high blood pressure?
Glomerus
What physiological part of the kidney makes urine either concentrated or diluted?
The collecting tubule
What are some of the main symptoms of urinary tract diseases? (x5)
- dysuria
- frequency
- urgency
- hematuria
- pain
What two things might you find on an examination of a pt with a urinary tract diesease?
CVA tenderness and suprapubic tenderness
What urinary tract disease is very common in athletes? How common?
Proteinuria (62%)
What causes proteinuria?
With exercise there is increased blood flow to the kidneys, which leads to more small proteins to be filtered through, and then all of the extra protein that was filtered cannot be absorbed
True or false:
In most cases of proteinuria, the extra protein in the urine is not indicative of disease.
True
What is the MOI for a kidney contusion/laceration?
Blow to the flank
What are the S/S of a kidney contusion/laceration? (x4) How should you deal with a suspected case of this?
Severe pain in the flank, hematuria, possible nausea and vomiting, and symptoms of shock; refer to the ED immediately (if they are hemodynamically stable they will stay overnight for observation, but if not stable then surgery will be required)
With traumatic hematuria, will the patient exhibit flank pain?
No they will have minimal to no flank pain
What does it indicate if urine is tea or cola colored?
That there is a lower concentration of blood in the urine than if it was redder
How would you deal with a traumatic hematuria?
Their exam will be normal (no CVA tenderness or peritoneal signs) but the urine dipstick will be positive for blood. They should cease all activity and be referred to the physician. Push fluids and repeat dipsticks daily until its clear…they allow non-contact activity and if they urine continues to be clear then allow contact activity
How can traumatic hematuria be prevented?
Empty bladder before contact sports
What is atraumatic hematuria? What is it caused by? Who does it affect the most?
Mild gross or microscopic hematuria that is very common in athletes (especially with long runs or intense exercise–20% of marathoners). It is caused by the bladder walls slapping against one another
What are two possible causes of false hematuria? Are they positive or negative on the dipstick analysis for blood in the urine? What about a microscope?
1) V8 juice or beets (- dipstick)
2) myoglobinuria (+ dipstick but - microscope)
What are six causes of true hematuria?
- Kidney stones
- Bladder infection
- Glomerulonephritis
- NSAIDs
- Kidney or bladder tumor
- Sickle cell trait
True or false:
Most traumatic hematurias will resolve with time.
True
What are some common causes of UTIs? (x3)
- Urethritis (stds)
- Cystitis
- Pyelonephritis
True or false:
UTIs are not very common.
False
What are the risk factors for a UTI? (x5)
- Female
- Age
- Urinary tract instrumentation/catheterization
- Urinary statis (not emptying the bladder…allows things to grow…?)
- Sexual activity
What are the two main sources of a UTI? What species of bacteria are usually the cause?
- bacteria from stool
- blood or lymphatic borne
- *E. coli, proteus, klebsiella, and enterobacter
What is cystitis? Describe the pathogenesis of this and pyelonephritits.
Infection of the bladder…if left untreated then theres virulent bactera–>obstruction leading to reflux of the bladder–> the infection travels up the ureters and to the kidneys
What are the S/S of cystitis? (x6)
Dysuria Urgency Frequency Fever Suprapubic (mostly) or flank pain Tenderness over the suprapubic area
If a patient is suffering from pyelonephritis, how will they present as compared to cystitis?
They will have the same symptoms as cystitis but will be more ill, have more flank pain or back pain, a higher fever, chills, nausea and vomiting, and CVA tenderness
True or false:
If someone has an uncomplicated UTI, the typical treatment includes an i.v. of medicine.
False…this is for a complicated UTI
True or false:
The old wives’ tale of cranberry juice being helpful for an UTI is correct.
True because there is bacteria static in the juice that can help
True or false:
Carbonated beverages cause UTIs.
False…but the extra acidity can mimic UTI problems??
What is incidence of new cases of the following STDs each year?
Chlamydia, gonorrhea, syphilis, herpes, HPV, and tricomonas?
Chlamydia= 3 million Gonorrhea= 650,000 Syphilis= 70,000 Herpes= 1 million HPV- 5.5 million Tricomonas= 5 million
How are STDs spread? (x3)
Genital, oral, and rectal
When does urethritis (std) develop symptoms? What are the S/S? (x3)
4 days to 2 weeks after contact with an infected partner. S/S= urethral discharge, dysuria, and urethral itching between urinations.
What percentage of men are asymptomatic with urethritis> Women?
Males- 25%
Females- 75%
When does vaginitis(std) develop symptoms? What are the S/S? (x3)
4 days to 2 weeks after contact with an infected partner. S/S- vaginal discharge, itching, and odor.
What is another common cause of vaginitis besides as an STD?
Yeast (candida)…this is common after antibiotics
How is a yeast infection treated?
Topical or oral antifungal
What are the S/S of herpes? (x3)
Parasthesias, painful blisters on an erythmeatous base, and recurrences
What is the treatment for herpes?
Antiviral medications, decrease the length of the treatment, or suppressive treatment (taking antiviral all the time so as to help the outbreaks happen less often)
What causes genital warts?
Human papillomavirus (HPV)
Does HPV increase or decrease a pt’s risk for cervical cancer?
Increase
What is the medical term for a kidney stone?
Nephrolithiasis
What percentage of kidney stones occur in men? Women?
Men- 15%
Women- 7%
What is the most common type of kidney stone? What are the other three types?
Most common- calcium oxalate…others= calcium phosphate, uric acid, and struvite
A combination of three factors makes up the pathogenesis of kidney stones. What are these three factors?
1) increased concentration of calculi components
2) lack of components that inhibit stone formation
3) organic material (dead cells that line the tubules) that serves as a matrix
What are the risk factors for kidney stone development? (x8)
Male, increasing age, low urine volume, SE US/Mediterranean/Middle East, increase dietary uptake (of protein, salt, or oxalate–tea), decreased dietary calcium, hyperparathyroidism, and acidosis
What are the three most common locations for a kidney stone?
1) Kidney (at the isthmus)
2) Iliac vessels (where they cross over the ureter)
3) Bladder (where the ureters insert)
What are the S/S of a kidney stone? (x5)
Renal colic (cramping pain)–excruciating flank and abdominal pain that may radiate to the scrotum or labia, nausea/vomitting, diaphoresis (sweating), urgency, and frequency
True or false:
As a primary method of treatment for kidney stones, it is common for the doctors to want the patient to try to “catch” the stone when they pass it so it can be analyzed.
True
If primary methods of treatment for a kidney stone don’t work, what would the possible three next steps be?
Lithotripsy, cystoscopy, and surgery
How can you help prevent the reoccurance of a kidney stone?
Increase fluid intake, decrease dietary protein, decrease dietary oxalate (chocolate, nuts, dark green leafy veggies), and alkalinizing the urine.
What are the three etiologies of acute renal failure?
- Prerenal (before the kidney)
- Renal (in the kidney)
- Postrenal (in the urinary tract after the kidney)
What prerenal causes lead to acute renal failure?
Not enough blood flow to the kidneys (such as during shock, dehydration, hypertension, and vascular obstruction such as a blood clot in the renal artery)
What renal causes lead to acute renal failure?
1) Nephrotic syndrome (polyuria or massive edema)
2) Nephritic syndrome (hematuria, oliguria, or hypertension)
What causes nephrotic syndrome?
Damage to the basement menbrane of the glomerus (or the filter of the kidneys). This increase the permeability to the proteins, leading to a large loss of protein in the urine. This large loss of protein in the urine leads to polyuria to try and dilute the urine, and hypoalbuminemia because of the change in osmotic pressure leading to massive edema
