Question 1: A nephron is made up of:

• A glomerulus and a tubule
• The neurons and a capsule
• The loop of Henle and the capillary ball
• The bladder and the ureter

Answer:

• A glomerulus and a tubule

Question 2: Which of the following will increase the amount of solutes that will diffuse across the semipearmeable membrane?

• Higher equilibrium
• Lower equilibrium
• High concentration gradients
• Lower concentration gradients

Answer:

• High concentration gradients

Question 3: the buttonhole technique results in fewer infections, missed needle insertions,

hematomas and infiltrations. Steps for creating the buttonhole include:

• prepare the site with an approved antimicrobial, cannulate with a dull 16 guage needle
• remove the scab, cannulate the same site at the same angle, by the same caregiver with

sharp needles for 3-4 weeks to create a tunnel.

• rotating the needle sites with each cannulation to prevent one-site-itis
• alternating a dull needle to a sharp needle every other week

Answer:

• remove the scab, cannulate the same site at the same angle, by the same caregiver with sharp

needles for 3-4 weeks to create a tunnel Question 4: According to AAMI standards, bacteriologic testing for water and dialysate should

take place:

• yearly

Answer:

• monthly

• a gradual increase in venous pressure and blood flow

Answer:

• the appearance of air or foam in any bloodline

Answer:

• From an area of higher concentration

• increase on skin temperature at site of stenosis

Answer:

• changes in the thrill and bruit
