- B. Encouraging family dependence on health care systems
- C. Recognizing that the family is the constant in a child's life

Rationale: Family-centered care in pediatric nursing involves recognizing that the family is the constant in a child's life. This approach focuses on involving families in the care of the child, considering their preferences, needs, and beliefs. It acknowledges the important role that families play in the well-being of the child and aims to support and empower them in the care process. By centering care around the family, healthcare providers can ensure that the care provided is holistic, culturally sensitive, and tailored to meet the unique needs of the child and their family.
The renin-angiotensin-aldosterone system plays an important role in maintaining blood pressure. Which compound in this system is most powerful at raising blood pressure?
- A. Angiotensin I
- B. Angiotensin II
- C. Angiotensin III
- D. Renin
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.
