Which of the following is a major complication in a child with chronic renal failure?
Congestive heart failure.
Metabolic alkalosis.
Excessive excretion of blood urea nitrogen.
Hypokalemia.
The Correct Answer is A
Choice A reason: This is the correct choice. Congestive heart failure can occur in chronic renal failure due to fluid overload and the inability of the kidneys to manage fluid balance.
Choice B reason: Metabolic alkalosis is not typically a major complication of chronic renal failure; metabolic acidosis is more common due to the accumulation of acids in the body.
Choice C reason: Excessive excretion of blood urea nitrogen is not a complication; rather, in renal failure, the kidneys cannot excrete urea nitrogen effectively.
Choice D reason: Hypokalemia (low potassium) can occur, but it is not as major a complication as congestive heart failure in the context of chronic renal failure.

Explanation
Choice A reason: An elevated white blood count (WBC) is not typically a side effect of chemotherapy; in fact, chemotherapy often leads to a decreased WBC count.
Choice B reason: This is the correct choice. Bone marrow suppression is a common side effect of chemotherapy, leading to a decreased production of blood cells and necessitating precautions to prevent infection.
Choice C reason: T-cell mediated hypersensitivity is not a common side effect of chemotherapy that would dictate the type of precautions needed.
Choice D reason: Stomatitis is a possible side effect of chemotherapy, but it does not primarily determine the type of precautions required as bone marrow suppression does.
Correct Answer is A
Explanation
Choice A reason: This response is the most appropriate as it correctly identifies Down syndrome as a genetic condition caused by an extra chromosome and acknowledges that the exact cause of the chromosomal abnormality is unknown.
Choice B reason: This choice is incorrect because Down syndrome is not carried on the X chromosome nor is it inherited from the mother alone.
Choice C reason: This statement is false; Down syndrome is not caused by birth trauma but is a genetic disorder.
Choice D reason: This choice is misleading; while genetics play a role in Down syndrome, it is not typically inherited from both parents in the way this choice suggests.
