Correct Answer: A

Rationale: Pizza with a fruit plate is the most suitable choice for a 6-year-old child with hypokalemia due to its potassium content. Potassium-rich foods like fruits can help replenish potassium levels in the body, aiding in the treatment of hypokalemia.

Correct Answer: B

Rationale: The vital signs of bradycardia, hypertension, and irregular respirations indicate increased intracranial pressure. Bradycardia (heart rate of 48), hypertension (blood pressure of 148/74 mmHg), and irregular respirations are typical signs of increased intracranial pressure in a pediatric client with a traumatic brain injury and loss of consciousness.

Correct Answer: D

Rationale: The correct answer is D because infants' kidneys are less developed compared to older children, making them less efficient at concentrating urine. This results in a lower specific gravity in infants. The other choices do not directly explain why the specific gravity is lower in infants.

Correct Answer: C

Rationale: The correct answer is hypotonic dehydration. The combination of high hemoglobin and hematocrit with low serum sodium indicates hypotonic dehydration. In this condition, there is an excess of solutes relative to water, leading to higher red blood cell concentration (elevated hemoglobin and hematocrit) and low serum sodium levels.

Correct Answer: B

Rationale: The correct answer is B: Ileal conduit. The ileal conduit diverts urine to the colon, and the urine is excreted with the feces. Unlike urostomy, nephrostomy, and suprapubic placement, the ileal conduit does not require an external appliance, which can be less damaging to an adolescent's body image.
