Davita PCT Final Version Exam Questions and Answers
(2022/2023) (Verified Answers)
what treatment factors decrease K in the Kt/v to decrease?
not waiting 3-5 minutes after heparin, decreasing BFR, DFR, and BVP
what factors influence "V" in Kt/v
accurate data entry by nurses in snappy, sex age, weight, and amputation
what are the needle gauges and prescribed blood flow rates?
they are inversely related
17g 200-250
15g 250-350
15g 350-400
14 g 400 - 450
what is the procedure for post BUN lab draw?
if pt wants off early, still draw the labs and educate patient about the risks. Redraw next
time a pt runs full tx to show pt difference
what lab draw mistakes would falsely increase Kt/V
not waiting the full 15 seconds
What is important when monitoring weight and BP in AKI patients?
keep patients wet (hydrated) and avoid hypotensive episodes = cause renal ischemia
What do you need to consider in regards to CVCs?
follow P&P b/c the risk of infection is so high
Why is it important to know what caused a patients chronic renal failure?
we need to know about possible problems during data collection and assessment
What is the role of the PCT prior to tx initiation?
assessment of pt if any abnormal findings or if the pt is in an acute condition
what happens in the BP cuff is the wrong size
loose BP--> high reading
tight BP --> low reading
why is it so bad to squeeze the BP cuff if its connected to the machine?
it can damage the internal BP mechanism
Why is it so important that we document in the medical record?
it provides data for continuity and planning of care
when do pre-treatment data collection and assessment take place?
collection: before tx
assessment: w/in 1 hr if pt is stable
when is post-treatment data collection and assessment performed?
post treatment-- not before treatment or when they are disconnected
what are the consequences of poor or incomplete documentation
can open attack on your care
What are the six items needed in charting meds?
1. med/dosage
2. date/time
3. route
, 4. reason (remember this!)
5. pt response
6. signature
What are the 5 Ws to be used when completing an AOR?
who
what
when
where
why
how
What are the 4 consequences of sodium loading during dialysis?
1. increased thirst
2. increased fluid intake
3. increased intradialytic weight gain = htn
4. increased UFR
what is the purpose of UF profiling?
change the way fluid is remodeled during the tx and allows for vascular refilling
what are the consequences of hypovolemia during tx?
attempting to remove a lot of fluid --> hypovolemia during tx --> loss of renal function,
ischemia, and increased mortality rate
what must the machine's conductivity and pH reading supposed to be?
machine and manual conductivity: w/in +/-0.4
pH range: 6.9 - 7.6, measured to verify acid/base balance is in acceptable range
at what temperature does hemolysis occur?
42 degrees C
What do we do in a power outage?
remove venous line from air detector, clamp, before starting hand crank and be diligent
in watching for air in blood lines
what causes a high venous pressure alarm?
kink in tubing, clotting in venous drip chamber, infiltration, venous stenosis
what are the risks of doing things "your way" and not the P&P way?
it can lead to civil liabiliy
what makes dialysis pts more susceptible to healthcare acquired infections?
prolonged access to pts blood, and immunocompramised
why are dialysis pts at an increased risk for acquiring HAIs at the facility?
contact transmission
what is the most common transmission route for HAIs
contact transmission--> hands
what is the most important invention you can do to prevent HAIs?
handwashing
what is the most common infectious complication in hemodialyisis pts?
per the CDC, the most common factor contributing to bacteremia is use of CVCs
What germ causes the most common infections in hemodialysis pts?
MRSA which can remain on surfaces for days w/ plastic vinyl being most favorable to
their survival
why is wearing gloves so important?
