Which of the following data would a clinician consider as most indicative of acute renal failure?
 
  A)
  Alterations in blood pH; peripheral edema
  B)
  Increased nitrogenous waste levels; decreased glomerular filtration rate (GFR)
  C)
  Decreased serum creatinine and blood urea nitrogen (BUN); decreased potassium and calcium levels
  D)
  Decreased urine output; hematuria; increased GFR

Question 2

A male patient with a history of heavy alcohol use has been admitted to hospital for malnutrition and suspected pancreatitis.
 
  The patient's diagnostic workup suggests alcoholic ketoacidosis as a component of his current health problems. He is somewhat familiar with the effect that drinking has had on his nutrition and pancreas but is wholly unfamiliar with the significance of acid-base balance. How best could his care provider explain the concept to him?
  A)
  The chemical processes that take place throughout your body are thrown off very easily when your body is too acidic or not acidic enough.
  B)
  The multitude of chemical reactions that take place in your body depend on your body fluids being slightly acidic.
  C)
  The healthy function of your kidneys and your lungs requires a specific level of pH in your body.
  D)
  Your body is highly dependent on what food and fluid you consume to keep itself at a functioning level of slight nonacidity.

Answer to Question 1

Ans:
B

Feedback:

The hallmark of acute renal injury is azotemia, an accumulation of nitrogenous wastes such as creatinine, urea nitrogen, and uric acid, plus a decrease in the GFR of the kidneys. While pH alterations, edema, electrolyte imbalances, and decreased urine output may accompany acute renal failure, they are all potentially attributable to other pathologies. Creatinine, GFR, and BUN would unlikely rise during renal failure.

Answer to Question 2

Ans:
A

Feedback:

Metabolic activity is highly contingent on a narrow range of pH. Normal pH is slightly basic, not acidic, and appropriate pH is maintained by the lungs and kidneys, not vice versa. The action of the respiratory and renal systems, not particular food or fluid intake, has the most salient effect on the acid-base balance.
