INCORRECT ULTRAFILTRATION RATE

ANTIHYPERTENSIVE MEDICATIONS

Question 7: IF A HIGH VENOUS PRESSURE MONITOR ALARM OCCURS DURING DIALYSIS,

YOU WOULD FIRST

Answer:

NO FLUID EXCESS IN THE

Answer:

INTERSTITIAL AND VASCULAR COMPARTMENT

Question 9: THE BLOOD LEAK DETECTOR IN MOST DELIVERY SYSTEMS

Answer:

IS A PHOTOELECTRIC CELL PLACED IN THE EFFLUENT DIALYSIS FLUID CIRCUIT, WHICH

CONTINUOUSLY MEASURES THE OPTICAL DENSITY OF THE FLUID PUMPED THROUGH IT

Question 10: SEQUENTIAL ULTRAFILTRATION IS BEST DESCRIBED AS

Answer:

FLUID REMOVAL WITHOUT DIFFUSION DIALYSIS

Question 11: SOLUTIONS THAT HAVE A HIGHER OSMOLARITY THAN BODY FLUIDS ARE

Answer:

PAIN IN VASCULAR ACCESS, EXTREMITIES, AND/OR CHEST, ABDOMINAL CRAMPS, DYSPNES,
