Which statement is true regarding renal blood flow?
No autoregulation is found in renal blood flow.
The kidneys receive 50% of cardiac output.
The kidneys receive 1000-1200 mL of blood per minute.
The glomerular filtration rate (GFR) is not related to renal blood flow. - CORRECT
ANSWER -The kidneys receive almost a quarter of cardiac output.
A patient with untreated strep throat is more likely to have with kidneys - CORRECT
ANSWER -Nephritic syndrome is caused by an antibody/antigen reaction seen after
group a-beta hemolytic strep. Antistreptolysin is produced in the antibody/antigen
reaction. You can use the HAD STREP mnemonic to help you remember:
H = hypertension
A = +ASO (antistreptolysin O)
D = decreased GFR (glomerular filtration rate)
STREP = Streptococcus
Briefly explain why edema occurs with nephritic syndrome. - CORRECT ANSWER -
Inflammation in the nephron causes increased permeability in the nephron.
Describe the pathology of nephrotic syndrome.
, Submit and Compare, displayed below - CORRECT ANSWER -Nephrotic syndrome is
caused by damage to the filtering system in the kidney. Massive amounts of protein are
lost in the urine which depletes the blood of albumin. The patient often presents with
frothy urine and anasarca (not hematuria).
Explain why patients with nephrotic syndrome are at high risk for infection. -
CORRECT ANSWER -Nephrotic syndrome is an idiopathic condition often treated with
corticosteroids and/or immunosuppressants. Massive swelling puts skin at risk for
breakdown because the skin becomes friable and fluid filled
What is the two-word technical term for kidney stones? - CORRECT ANSWER -Renal
calculi is the technical term for kidney stones.
Describe what caused the pain that sent this patient to the emergency department. with
renal calculi - CORRECT ANSWER -At least one of the renal calculi was obstructing the
ureter because it was too large to move easily through the ureter.
List the adverse effects that could arise if a renal calculus completely blocks a ureter,
and briefly explain why. - CORRECT ANSWER -Hydroureter and hydronephrosis
could occur because the kidney continues to produce urine even if the ureter is blocked.
The blockage would cause urine to accumulate, dilating the ureter first, and then the
renal pelvis. This leads to a buildup of waste products in the body and can lead to
kidney injury.
Explain why it is important for the patient to learn to increase her fluid intake to 8-10
glasses of fluid per day. with renal calculi - CORRECT ANSWER -Drinking 8-10 glasses
of fluid per day will keep her urine dilute, which will help keep renal calculi from
forming and will help move stones along the passageway to excretion should they
recur.
Produced in the mouth and breaks down starch - CORRECT ANSWER -Amylase
Produced in the stomach and breaks down protiens - CORRECT ANSWER -pepsin
