Correct Answer: D

Rationale: The correct answer is D: Hypertension. Nephroblastoma, also known as Wilms' tumor, often causes hypertension due to its impact on the kidney, which plays a role in regulating blood pressure. Atrial fibrillation (choice A) and endocarditis (choice B) are not typically associated with nephroblastoma. Hyperlipidemia (choice C) is also not a common clinical manifestation of nephroblastoma.

Correct Answer: B

Rationale: Hypotonic dehydration occurs when the loss of electrolytes exceeds the loss of water, leading to a decrease in plasma osmolarity. This often occurs when sodium loss is greater than water loss, as in diarrhea or vomiting.

Correct Answer: C

Rationale: Infants have immature kidneys that are less efficient at concentrating urine, making them more susceptible to fluid imbalances. Their higher surface area to volume ratio also contributes to greater insensible fluid losses.

Correct Answer: C

Rationale: The correct answer is C. By age 5, children should be able to state their name and address. If a child cannot do this, it may indicate a developmental delay that requires further assessment. Choices A, B, and D do not indicate a need for further education as they reflect typical developmental milestones for preschool-age children, such as gradually improving counting skills, asking many questions, and improving speech clarity over time.

Correct Answer: A

Rationale: Decompensated shock is characterized by signs such as oliguria, confusion, pale extremities, hypotension, and a thready pulse. These indicate that the body is no longer able to maintain adequate circulation to vital organs.
