Shave hair with razor immediately before the incision
Remove hair with a depilatory the night before surgery
Remove hair with clippers the night before surgery

For patients who require hemodialysis, which type of vascular access device (VAD) poses the
lowest risk of infection?
Arteriovenous graft
Subclavian catheter
Arteriovenous fistula
Right internal jugular catheter - ANSWER Arteriovenous fistula. Placed in the arm rather
the thigh. Patients w/ catheters have 7x the risk of infection (subclavian catheters have high
risk). Patients w/ chronic kidney disease should have vascular access preserved and AV fistu-
las created as soon as possible
Which items in medical facility require most frequent environmental cleaning?:
Bedrails
Floors
Ventilation grilles
Window curtains - ANSWER Bedrails, because they are high touch. Others only require
frequent cleaning if visibly soiled

A distribution curve that has a skew value of +3 will exhibit what shape? - ANSWER An
enlarged tail to the right. This is indicating there are more data than expected on the right
(or positive) end of the distribution curve. Skew is positive when the mean is greater than
the median, negative when the mean is lesser than the median. Value of 0 = normal bell
curve with no skew. Negative value = skew to the left.
