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:
Reducing the dosage of methotrexate during pregnancy is not a safe option because methotrexate is contraindicated during pregnancy due to its potential to cause birth defects and other adverse pregnancy outcomes.
Choice B reason:
While dietary modifications may be necessary during pregnancy, this is not specifically related to the use of methotrexate. The primary concern with methotrexate and pregnancy is the risk it poses to the developing fetus, not dietary interactions.
Choice C reason:
Breastfeeding while taking methotrexate is not recommended. Methotrexate can be excreted in breast milk and may harm a nursing infant.
Choice D reason:
Methotrexate should indeed be discontinued at least 3 months prior to a planned pregnancy. This is to ensure that the drug is completely cleared from the body, as it can cause serious birth defects and other pregnancy-related complications.
Correct Answer is C
Explanation
Choice A reason:
Lightheadedness is generally not an indication of effective treatment for dehydration. It is often a symptom of dehydration itself, as it can result from decreased blood volume and reduced blood flow to the brain. Effective rehydration should alleviate symptoms like lightheadedness, not present as an indication of it.
Choice B reason:
Decreased pulse pressure may indicate a drop in the volume of blood circulating through the body, which is not a sign of effective rehydration. Pulse pressure is the difference between systolic and diastolic blood pressure readings, and a narrow pulse pressure can be a sign of hypovolemia, or low blood volume, often due to dehydration.
Choice C reason:
Urine output of 75 mL in 1 hr can be considered within the normal range of urine output for an adult, which is typically about 0.5 to 1 mL/kg/hr⁵. This indicates that the kidneys are functioning and the body is excreting waste, suggesting effective rehydration.
Choice D reason:
A urine specific gravity of 1.038 is higher than the normal range of 1.005 to 1.030[^10^]. This indicates concentrated urine, which is commonly seen in dehydration as the body attempts to conserve water. Therefore, this is not an indication of effective treatment for dehydration.
