Patients will typically have a dialysis catheter, be careful to avoid catheter related infections

44
Q

How do you protect kidneys from further injury AKI

A

Avoid substances to the kidneys which may be toxic (radiographic contrast, amphotericin b, low dose aspirin, NSAIDs)

45
Q

What is important when monitoring weight and BP AKI

A

Keep a little extra fluid on the patient so it is available to the kidneys when they start filtering/ultra-filtrating on their own

46
Q

AKI patients are at increased risk for which complications?

A

Hypovolemia and hypotension

47
Q

What is the difference between OSHA and CMS infection control requirements?

Handwashing with soap and water per policy is the only acceptable hand hygiene

50
Q

51
Q

What organism causes the most common infections in hemodialysis patients

A

Methicillin resistant staphylococcus aureus (MRSA)
Must pay attention to infection control. Proper hand hygiene, cleaning and disinfecting procedures to prevent the spread of infection (viable on surfaces for days)

52
Q

What is the importance of wearing gloves

A

Reduces the risk of hand contamination and prevents the transfer of organisms already on hands to a patient

53
Q

Why do you need to preform hand hygiene before and after wearing gloves

A

Gloves are not impervious and have microscopic pores

54
Q

Who can use clean sinks for hand washing

A

Teammates and patients

55
Q

Is a cleaned dialysis machine considered a clean area

A

No

56
Q

How can you tell when an area or sink is clean or dirty in your facility

A

It is clearly labeled with a clean or dirty sign

57
Q

What is a strike through of an external pressure transducer and why is it of concern

A

It is when fluid could have entered the machine and contaminated the internal pressure transducer protector providing a reservoir for microorganisms and causing subsequent patient blood infections

58
Q

When should sharps containers be removed from the treatment floor

A

When they are 3/4 full

59
Q

Explain the HBV classification and state which test is preformed monthly on HBV susceptible patients

A

HBsAG: hepatitis B surface antigen- tested monthly for susceptible pts and non-responders

HBsAB (anti-HBs) hepatitis B surface antibody

HBcAb (anti HBc) hepatitis B core antibody

60
Q

How do surveyors verify teammates have completed infection control training and education

A

Documentation of infection control training in the teammates file or transcript

61
Q

Which patient care assignments are appropriate when caring for hepatitis B patients

A

Caring for HBsAG positive and hepatitis B immune patients at the same time

Caring for hepatitis B susceptible patients and those in the process of receiving the vaccination at the same time

Caring for hepatitis B immune and susceptible patients at the same time

62
Q

State 3 strategies recommended to decrease the risk of infection when working with a CVC

A

Using a face mask when lumens or exit site is exposed

Wearing clean gloves and avoid touching exposed surfaces

Minimizing catheter lumen or exit sites from being exposed

63
Q

What is the most common transmission route for HAIs

A

Contact transmission

64
Q

What is the reason that dialysis patients are at increased risk for acquiring a HAI at the facility

A

CKD patients are immunosuppressed and more vulnerable to infection. Infection is the second most common cause of death in dialysis patients

65
Q

What contributes to hemodialysis patients being placed at increased risk for acquiring a HAI at the facility

A

Kidney failure weakens the immune system making patients more vulnerable to infection. Dialysis patients oftentimes have multiple comorbid conditions, which further weakens the immune system. The dialysis procedure itself requires prolonged access to the patients blood, especially those involving CVC accesses, making them more at risk

66
Q

What is the correct procedure in regards to your hands when you have casual contact with a patient

A

Gloves are not necessary for casual contact, but hand hygiene is required after every direct contact with a patient and between patient contacts, even if it is casual

Preforming hand hygiene

A

45x

69
Q

What are the two most frequent physician potassium strengths of dialysate concentrate used at Davita

A

2.0 K and 3.0 K

70
Q

A

Glomerulus

71
Q

What are the two waste products removed by dialysis that we monitor with monthly labs

A

Blood, Urea Nitrogen BUN
Creatinine

72
Q

How often are dialysis machine alarm tests performed

A

Before initiation of each patient treatment

73
Q

Checking independent conductivity

A

The manual conductivity value must match +/- 0.4 mS on the Fresenius (FMC) 2008K and k2 dialysis delivery system displayed conductivity in

Checking independent conductivity is not required when using Fresenius 2008T or T Blue Star models

The B Braun machine does not require manual conductivity testing but conductivity must be verified on the ENDLF machine screen

74
Q

What is the safe dialysate pH range

A

Between 6.9-7.6

75
Q

Why is it important for patient care teammates to know when the water treatment system disinfection was preformed

A

Brother end to end disinfection process will also introduce the disinfectant solution to the dialysis delivery systems through there water inlet lines

76
Q

Following recirculation, how long can a dialyzer and blood lines be set up

A

2 hours

77
Q

Why are the Dialyzer and blood lines not used for dialysis treatment once recirculating for longer than 2 hours

A

Because of the potential for bacterial growth

78
Q

What is the correct procedure for residual bleach testing after the chemical disinfection of loops and equipment fluid pathways

A

 Residual, bleach testing should be performed after bleach, disinfection, and prior to equipment use
