renal wrong Flashcards
what is a normal range for an anion gap
10-16
causes of a metabolic acidosis with a normal anion gap
ABCD
addisons, bicarb loss (vomiting etc), chloride (saline), drugs (acetaxolamide)
(lack of removing acid)
What does low c3/c4 indicated
give an example of a renal affected disease which would show low c3/c4
Active immune system as complement proteins are being used up.
Eg SLE shows there is low C3/C4
at the beginning of the loop of henle the fluid is…tonic, at the tip of the loop the fluid is…. tonic and as the flui dleave the loop to enter the distal tubule it is … tonic
isotonic
hypertonic
hypotonic
as the fluid at the tip has more fluid and salt etc than blood (1200mosmol vs 300mosmol)
and as it enters the distal tubule it is only 200mosmol (vs 300mosmol of blood)
how does urine get to the bladder from the kidneys
peristaltic contraction of the smooth muscle of the ureters
do you get hypokalemia or hyperkalemia in metabolic acidosis
hypokalemia
signs of hypocalcemia
tingling of hands and feet
normocytic anaemia, low platelets and AKI following diarrhoeal illness- consider…
Haemolytic uraemic syndrome
what is the main differentiation between post streptococcal glomerulonephritis and IgA glomerulonephritis
both present with nephritic syndrome
IgA occurs 2 days after URTI
PSGN occurs 1-2 weeks after URTI
how does acute interstitial nephritis present
‘allergic’ type picture consisting usually of raised urinary WCC, IgE, and eosinophils, alongside impaired renal function
most common causitive organism of peritonitis secondary to peritoneal dialysis
coagulese negative staphylococcus: staph epidermis
how does myeloma present
anaemia, hypercalcaemia, bone pain and AKI
(as well as other general cancer symptome eg weight loss)
when to give dialysis
A – Acidosis (severe and not responding to treatment)
E – Electrolyte abnormalities (severe and unresponsive hyperkalaemia)
I – Intoxication (overdose of certain medications)
O – Oedema (severe and unresponsive pulmonary oedema)
U – Uraemia symptoms such as seizures or reduced consciousness
what is the most common renal cancer
renal clear cell carcinoma
who is at risk of renal medullary carcinoma
young males with sickle cell trait
