A nurse is reviewing the laboratory results of an adolescent who has chronic glomerulonephritis. Which of the following findings should the nurse expect?

BUN 50 mg/dL.

Serum phosphorus 4.0 mg/dL.

Serum potassium.8 mEq/L.

Absence of proteinuria.

Answer and Explanation

The Correct Answer is A

Chronic glomerulonephritis is a condition that causes inﬂammation of the glomeruli, which are tiny ﬁltering units in the kidneys.
This can lead to poor kidney function and an increase in waste products in the bloodstream.
Blood urea nitrogen (BUN) is a waste product that is normally ﬁltered by the kidneys and excreted in urine.
A BUN level of 50 mg/dL is higher than the normal range, indicating poor kidney function.
Choice B is incorrect because a serum phosphorus level of 4.0 mg/dL is within
the normal range for adults.
Choice C is incorrect because a serum potassium level of.8 mEq/L is within the normal range for adults.
Choice D is incorrect because proteinuria (the presence of protein in urine) is a
common ﬁnding in glomerulonephritis.

Correct Answer is C

Explanation

In the event of a potential poisoning, the ﬁrst step should be to contact the poison control center for guidance on how to proceed.
Choice A is not correct because rapid infusion of deferoxamine is not the ﬁrst step in managing iron overdose.
Choice B is not correct because syrup of ipecac is no longer recommended for use in cases of poisoning.
Choice D is not correct because providing a high-carbohydrate meal is not an appropriate intervention for iron overdose.

A. Negative Chvostek's sign. B. Muscle tremors. C. Dry, sticky mucous membranes. D. Polyuria.

Correct Answer is B

Explanation

A calcium level of 8.0 mg/dL is below the normal range for adults, which is 8.8 to 10.4 mg/dL.
This condition is known as hypocalcemia and can cause muscle spasms and aches.
Choice A is incorrect because a positive Chvostek’s sign, not a negative one, is a clinical sign of hypocalcemia.
Choice C is incorrect because dry, sticky mucous membranes are not a symptom of hypocalcemia.
Choice D is incorrect because polyuria (frequent urination) is a symptom of hypercalcemia (high calcium levels), not hypocalcemia.
