A nurse is explaining the role of blood tests in diagnosing glomerulonephritis to a client. Which blood test is frequently performed to assess kidney function and determine the glomerular filtration rate (GFR)?
Complete blood count (CBC)
Blood urea nitrogen (BUN)
Serum creatinine
C-reactive protein (CRP)
The Correct Answer is C
A) Incorrect. A complete blood count (CBC) provides information about red and white blood cell counts and is not primarily used to assess kidney function or GFR.
B) Incorrect. Blood urea nitrogen (BUN) is a blood test that can be influenced by factors other than kidney function and is not a direct measure of GFR.
C) Correct. Serum creatinine is a commonly used blood test to assess kidney function and estimate the glomerular filtration rate (GFR).
D) Incorrect. C-reactive protein (CRP) is a marker of inflammation and is not typically used to assess kidney function or GFR in glomerulonephritis.

Correct Answer is B
Explanation
A) Incorrect. ACE inhibitors do not enhance sodium reabsorption; they actually decrease sodium reabsorption in the kidneys.
B) Correct. ACE inhibitors are commonly prescribed to reduce proteinuria (excessive protein in the urine), which is a common symptom of glomerulonephritis.
C) Incorrect. ACE inhibitors do not promote potassium excretion; they can lead to hyperkalemia (high potassium levels) in some cases.
D) Incorrect. While ACE inhibitors can affect aldosterone levels, their primary role in glomerulonephritis is to reduce proteinuria and manage blood pressure.
Correct Answer is B
Explanation
A) Incorrect. Hypertension can be a complication of glomerulonephritis, but it is not a cause of poststreptococcal glomerulonephritis (PSGN).
B) Correct. PSGN is often linked to recent respiratory infections, particularly those caused by streptococcal bacteria.
C) Incorrect. Diabetes mellitus is not a common cause of PSGN.
D) Incorrect. Familial history may be a risk factor for some kidney diseases, but it is not a direct cause of PSGN.
