Question 1

What is the primary formula used to calculate the estimated glomerular filtration rate (eGFR) in adults?

Accepted Answer

Modification of Diet in Renal Disease (MDRD) equation

Answer

Schwartz formula

Answer

Cockcroft-Gault equation

Answer

Brescia method

Question 2

Which substance is primarily measured in the blood to estimate eGFR?

Accepted Answer

Creatinine

Answer

Urea

Answer

Albumin

Answer

Bilirubin

Question 3

What impact does a higher muscle mass have on the estimated glomerular filtration rate (eGFR)?

Accepted Answer

It may lead to a higher eGFR value.

Answer

It has no impact on eGFR.

Answer

It artificially inflates serum creatinine levels.

Answer

It may lead to a lower eGFR value.

Question 4

In which scenario might the eGFR not accurately reflect kidney function?

Accepted Answer

In patients with rapidly changing kidney function

Answer

In patients with diabetes

Answer

In athletes with high muscle mass

Answer

In patients who are older than 70

Question 5

What is the significance of adjusting the estimated glomerular filtration rate (eGFR) for body surface area (BSA)?

Accepted Answer

To provide a more accurate assessment of kidney function relative to body size

Answer

To increase the eGFR value

Answer

To simplify the calculation

Answer

To account for age differences

Question 6

What is the recommended threshold eGFR value indicating moderate to severe kidney damage?

Accepted Answer

Less than 60 mL/min/1.73 m²

Answer

Less than 30 mL/min/1.73 m²

Answer

Less than 120 mL/min/1.73 m²

Answer

Less than 90 mL/min/1.73 m²

Question 7

Which of the following factors can cause an increase in serum creatinine levels, potentially affecting eGFR calculations?

Accepted Answer

Dehydration

Answer

Increased fluid intake

Answer

Regular aerobic exercise

Answer

Low protein diet

Question 8

Which factor is NOT typically used in the calculation of eGFR using the MDRD equation?

Accepted Answer

Height

Answer

Sex

Answer

Age

Answer

Serum creatinine

Question 9

What role does race play in the estimation of eGFR using the MDRD equation?

Accepted Answer

It may adjust for differences in muscle mass and dietary habits.

Answer

It is only used in clinical trials.

Answer

It is only considered for African Americans.

Answer

It has no effect on eGFR calculation.

Question 10

What does a decrease in eGFR indicate regarding kidney function?

Accepted Answer

Progressive decline in kidney function

Answer

Improved kidney function

Answer

Stable kidney health

Answer

Increased kidney filtration
