Quiz zum Vortrag
Which of the following explains why the serum creatinine level is a useful measure for estimating GFR?
- Creatinine is freely filtered across the glomerulus and is neither reabsorbed nor metabolized by the kidneys.
- Serum creatinine can be used to estimate the GFR in individuals with unstable kidney function.
- Creatinine production remains constant among individuals with significant variations in muscle mass.
- Serum creatinine is sensitive to changes in GFR in the early stages.
Which of the following statements regarding serum creatinine and GFR is true?
- In the initial stages of renal failure, a small rise in serum creatinine reflects a marked change in GFR.
- Creatinine clearance slightly underestimates GFR because creatinine is moderately secreted by renal tubules.
- The relationship between serum GFR and creatinine clearance is inversely proportional and linear.
- The relationship between serum creatinine and GFR is directly proportional and nonlinear.
Which of the following variables is not used in the CKD-EPI equation?
- Body mass index
- Age
- Ethnicity
- Sex
- Serum creatinine
Which of the following statements is correct regarding GFR estimation equations?
- The MDRD study equation is less accurate than the CKD-EPI equation when GFR is > 60 mL/min/1.73 m^2.
- MDRD study equation has no clinical value when GFR is < 60 mL/min/1.73 m^2.
- CKD-EPI provides an accurate estimate of GFR in patients with acute kidney injury.
- These equations estimate GFR by incorporating muscle mass and creatinine clearance.
Which of the following medications can increase serum creatinine without a change in overall kidney function?
- Trimethoprim
- Naproxen
- Valproate
- Gentamicin
- Atorvastatin
Which of the following is used to describe the rate at which a substance is removed from the body by the kidneys?
- Clearance
- GFR
- Effective renal plasma flow
- Secretion rate
Which of the following is NOT an important reason to measure GFR?
- To assess acid/base status
- To dose medications cleared by the kidneys
- To evaluate patients with kidney disorders
- To know when to avoid nephrotoxic medications
- To stage chronic kidney disease

Una explicación completa y sencilla, me gustó que dió ejemplos de casos. Se la recomiendo a estudiantes de medicina en etapa clínica y como repaso para profesionales de atención primaria.
