A nurse is caring for a male client who has chronic glomerulonephritis. Which of the following findings should the nurse expect?
Urine specific gravity 1.035
Serum creatinine 7 mg/dL
Creatinine clearance 120 mL/min
BUN 15 mg/dL
The Correct Answer is B
Choice A reason:
Urine specific gravity is a measure of urine concentration. The normal range is typically from 1.005 to 1.030. A specific gravity of 1.035 indicates very concentrated urine, which could be due to dehydration or other factors, but it is not specifically indicative of chronic glomerulonephritis.
Choice B reason:
Serum creatinine is a waste product from the normal breakdown of muscle tissue. Normal levels are approximately 0.6 to 1.2 mg/dL for males. A level of 7 mg/dL is significantly elevated and can indicate severe kidney dysfunction, which is consistent with chronic glomerulonephritis. This condition can lead to a decreased ability of the kidneys to filter waste, causing an accumulation of creatinine in the blood.
Choice C reason:
Creatinine clearance is a test that measures how well creatinine is removed from the blood by the kidneys. The normal range is about 95 to 120 mL/min. A clearance of 120 mL/min is within the normal range and would not typically be expected in a client with chronic glomerulonephritis, as this condition usually results in reduced kidney function.
Choice D reason:
Blood urea nitrogen (BUN) is another waste product filtered by the kidneys. Normal BUN levels are between 7 and 20 mg/dL. A BUN of 15 mg/dL is within the normal range and does not necessarily indicate kidney dysfunction from chronic glomerulonephritis.

Correct Answer is D
Explanation
Choice A reason:
The lack of insulin production by the pancreas is related to diabetes mellitus, not Addison's disease. Insulin is a hormone that regulates blood sugar levels, and its deficiency leads to diabetes, not Addison's disease.
Choice B reason:
The overproduction of growth hormone by the pituitary gland leads to conditions such as acromegaly or gigantism, depending on the age at which the hormone levels become elevated. It is not related to Addison's disease, which involves the adrenal glands, not the pituitary gland.
Choice C reason:
The overproduction of parathormone by the parathyroid glands leads to hyperparathyroidism, which can cause a variety of symptoms including bone pain, kidney stones, and abdominal pain. This condition is not related to Addison's disease.
Choice D reason:
Addison's disease is indeed caused by the lack of production of hormones by the adrenal glands, particularly cortisol and aldosterone. Aldosterone helps to maintain blood pressure and the balance of sodium and potassium in the blood. When the adrenal glands do not produce enough aldosterone, it can lead to symptoms such as low blood pressure and salt cravings, which are characteristic of Addison's disease.
Correct Answer is B
Explanation
Choice A reason:
The Mantoux test, also known as the tuberculin skin test, is used to detect latent TB infection but is not the most reliable for confirming active pulmonary TB. It can indicate if someone has been infected with TB bacteria, but it cannot differentiate between latent and active TB.
Choice B reason:
A sputum culture for acid-fast bacillus is the gold standard for diagnosing active pulmonary TB. It involves culturing a sample of sputum (phlegm) to see if TB bacteria grow, which confirms the diagnosis. This test is the most definitive and reliable method, although it may take several weeks to obtain results.
Choice C reason:
A sputum smear can detect TB bacteria in sputum samples quickly, but it is less sensitive than a culture. It can miss cases, especially if the bacterial load is low. Therefore, while useful for initial screening, it is not as reliable as a culture for confirming active TB.
Choice D reason:
A chest x-ray can show signs suggestive of TB, such as infiltrates or cavities in the lungs, but it cannot confirm the presence of TB bacteria. It is a supportive diagnostic tool but not definitive for active TB diagnosis.
