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.

Correct Answer is B
Explanation
Choice A reason: Assessing pedal pulses is important, but it does not provide complete information about the circulatory status of the infant.
Choice B reason: This is the correct choice. Discrepancies in pulse strength between the upper and lower extremities may indicate a cardiovascular problem such as coarctation of the aorta, which can be further evaluated by comparing blood pressures in all four extremities.
Choice C reason: Lower extremity reflexes are not directly related to the strength of pulses.
Choice D reason: Hemoglobin and hematocrit values are important but would not be the next step in assessing the significance of the difference in pulse strength.
Correct Answer is C
Explanation
Choice A reason: This choice is incorrect. It is not unusual for a 5-year-old to have difficulty with zippers.
Choice B reason: This choice is incorrect. Reciting a phone number is not expected of a 2-year-old.
Choice C reason: This is one of the correct choices. A 6-year-old should be able to sit still for a short story, and difficulty doing so may indicate a developmental delay.
Choice D reason: This choice is incorrect. A 2-year-old typically does not have the fine motor skills to cut with scissors.
Choice E reason: This is one of the correct choices. An 18-month-old should be starting to phrase simple sentences, and the inability to do so may indicate a developmental delay.
