Rationale: Periorbital ecchymosis, also known as raccoon eyes, is a classic sign of a basilar skull fracture. It presents as bruising around the eyes due to blood collecting in the tissues. Monitoring for periorbital ecchymosis is crucial in assessing a pediatric client with a basilar skull fracture because it can indicate the presence of this serious injury.

Correct Answer: B

Rationale: Angiotensin II is the most potent compound in the renin-angiotensin-aldosterone system for raising blood pressure. It acts as a powerful vasoconstrictor, leading to increased systemic vascular resistance. Angiotensin II is formed from angiotensin I through the action of the angiotensin-converting enzyme. While renin initiates the cascade by converting angiotensinogen to angiotensin I, it is angiotensin II that exerts the strongest pressor effect.

Correct Answer: B

Rationale: In nephrotic syndrome, edema is a common symptom that is generalized and not easily noticeable, even by parents.

This can be an initial indicator of nephrosis and may prompt further evaluation and intervention.

Correct Answer: B
