Correct Answer is A

Explanation

A. Body weight – Correct; the best indicator of fluid loss in infants is a change in weight because infants have higher water content and small changes can significantly impact hydration status.

B. Blood pressure – Incorrect; infants can maintain blood pressure until dehydration becomes severe.

C. Respiratory rate – Incorrect; respiratory rate may increase with dehydration but is not the most reliable indicator.

D. Skin integrity – Incorrect; poor skin turgor is a sign of dehydration, but weight loss is more objective and accurate.

A. Lightening B. Decreasing chest diameter C. Decreased carbon dioxide production D. Hyperventilation

Correct Answer is A

Explanation

A. Lightening – Correct; "lightening" occurs when the fetal head descends into the pelvis, reducing pressure on the diaphragm, making it easier to breathe.

B. Decreasing chest diameter – Incorrect; the chest diameter does not decrease; instead, the diaphragm moves upward due to uterine growth.

C. Decreased carbon dioxide production – Incorrect; CO₂ production remains stable during pregnancy.

D. Hyperventilation – Incorrect; while pregnancy increases respiratory effort, the client is experiencing relief, not hyperventilation.
