, Question 1
Each of the following statements are true regarding control over the GFR except:
Correct Answer
The RAA responds when blood pressure rises above normal limits.
(false b/c the RAA responds when blood pressure drops below normal limits.)
Rationale:
The Renin-Angiotensin-Aldosterone (RAA) system responds to low blood volume or decreased blood pressure by increasing blood
pressure through vasoconstriction and fluid retention, thereby correcting the drop in blood pressure. By responding to low blood
pressure, the statement that the RAA system responds when blood pressure drops below normal limits is a correct exception to the
assertion that it only responds when blood pressure rises above normal limits.
Question 2
Which of the following statements is false regarding ADH?
Correct Answer
Elevated levels of ADH will lead to dilute urine.
(false b/c DECREASED levels of ADH will lead to dilute urine)
Rationale:
ADH (Antidiuretic Hormone) regulates water reabsorption in the kidneys, and high levels of ADH increase water reabsorption, leading
to concentrated urine. Conversely, low levels of ADH decrease water reabsorption, resulting in dilute urine, making the statement false
because elevated ADH leads to concentrated urine, not dilute urine.
Question 3
Cortical nephrons are characterized by the following except:
Correct Answer
they originate deep in the cortex (false b/c they originate superficially in the cortex)
Rationale:
Cortical nephrons originate superficially in the cortex, meaning they are found close to the surface of the kidney, whereas true
nephrons originate deep within the renal cortex, closer to the medulla. This superficial origin is a key characteristic that distinguishes
cortical nephrons from true nephrons, making the statement about cortical nephrons originating deep in the cortex incorrect.
Question 4
Excess accumulation of fluid within the interstitial compartment is characteristic of which of the following fluid
imbalances?
Correct Answer
edema
Rationale:
The term "edema" accurately describes the condition because it specifically refers to the accumulation of excess fluid within the
interstitial compartment, which is the space between cells and tissues outside of blood vessels. This accumulation of fluid in the
interstitial space results from an imbalance in fluid distribution, either due to increased fluid leakage from blood vessels or decreased
fluid removal, leading to the characteristic swelling associated with edema.
