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:
Monitoring temperature is important postoperatively as it can indicate infection or inflammation. However, it is not the immediate priority following a thyroidectomy. The primary concern post-thyroidectomy is ensuring the airway is not compromised due to swelling or bleeding.
Choice B reason:
Monitoring urination is part of postoperative care to ensure kidney function and that the body is adequately eliminating fluids. While important, it is not the priority in the immediate postoperative period following a thyroidectomy.
Choice C reason:
Pain control is essential for patient comfort and recovery. However, while managing pain is a significant aspect of postoperative care, it is not the most critical priority following a thyroidectomy. The nurse must first ensure that the airway is clear.
Choice D reason:
Airway patency is the priority for monitoring a client post-thyroidectomy. Due to the proximity of the surgery to the trachea, there is a risk of swelling, hematoma, or other complications that could lead to airway obstruction. Ensuring the client has a patent airway is crucial to prevent respiratory distress or compromise.
Correct Answer is C
Explanation
Choice A reason:
Bradycardia, which is a slower than normal heart rate, is not typically associated with diabetes insipidus. Diabetes insipidus primarily affects the kidneys and fluid balance in the body, leading to frequent urination and thirst but not directly affecting heart rate.
Choice B reason:
Moist mucous membranes are not expected in diabetes insipidus. In fact, due to excessive urination, a person with diabetes insipidus is more likely to experience dry mucous membranes from dehydration unless they are adequately hydrating.
Choice C reason:
Urine specific gravity 1.002 is a key finding in diabetes insipidus. This condition is characterized by the excretion of large amounts of dilute urine with low specific gravity. Normal urine specific gravity ranges from 1.005 to 1.030⁴. A value of 1.002 indicates very dilute urine, which is consistent with the inability of the kidneys to concentrate urine in diabetes insipidus.
Choice D reason:
Bounding peripheral pulses are not a finding associated with diabetes insipidus. Bounding pulses may be associated with other conditions such as fever, anemia, or hyperthyroidism but not typically with diabetes insipidus.
