Renal

True or false.

Serum creatinine levels are slightly higher in men than women because men tend to have a larger muscle mass than women do

• True

• False

What does an elevated creatine level means?

Bun measures the effective of kidney excretion of

• creatine level

• urea nitrogen

• protein

• muscle mass

A serum creatine of ________or greater place a patient at risk for acute kidney injury from iodinated contrast media and some drugs.

Notify provider of increases in serum creatinine greater than_________baseline and urine ouput values of less than ________for 6 hours or more hours.

Bun is not always elevated with kidney disease and is not the best indicator of kidney function. What are other reasons for Bun elevations?

• dehydration

• infection

• low cardiac output

• cancer treatment

• steriod therapy

When elevation of both serum creatinine and BUN levels rises this may suggests_______that not related to dehydration or poor perfusion

Normal blood osmolarity

• 350-400

• 100-120

• 0-20

• 280-300

What happens when blood osmolarity is decreased

What happened when blood osmolarity is increased?

• vasopressin causes increase in water reabsorptions in the distal tubules as a result blood osmolarity is decreased

• vasopressin causes decrease in water reabsorptions in the distal tubules as a result blood osmolarity is increase

• vasopressin causes and equalization in water reabsorptions in the distal tubules as a result blood osmolarity is equalizes
