1. 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.

2. What type of characteristic is described in this scenario?

• A. Mode Change
• B. Social
• C. Enduring
• D. Situational

Correct answer: D

Rationale: The scenario describes a temporary change in Ava's emotional state due to a specific event - the fight with her friend. This aligns with the definition of a situational characteristic, which is influenced by specific circumstances or events. Ava's sadness and tearfulness in this situation are not reflective of a permanent trait but rather a response to a particular situation. Choices A, B, and C are incorrect. 'Mode Change' does not accurately describe the situation; 'Social' is too broad and does not specifically address Ava's emotional state change; 'Enduring' implies a long-lasting trait, which is not the case in this scenario.

3. The healthcare provider is caring for a 9-month-old infant who just returned from the postanesthesia care unit (PACU) after a shunt placement for hydrocephalus. Which healthcare provider prescription should the nurse question?

• A. Vital signs and neurologic checks hourly
• B. Small, frequent formula feedings
• C. Elevate the head of the bed
• D. Daily head circumference measurements

Correct answer: C

Rationale: Elevating the head of the bed in a child with hydrocephalus can potentially increase intracranial pressure. This can be counterproductive and may lead to complications after shunt placement surgery. Keeping the head of the bed flat or slightly elevated is often recommended to optimize cerebral perfusion and reduce the risk of increased intracranial pressure.

4. When teaching a parent of a 2-month-old infant with acute gastroenteritis who is bottle feeding, which of the following statements should the nurse include?

• A. Offer Pedialyte between formula feedings.
• B. Feed the infant every 6 hours.
• C. Give diluted apple juice if the infant becomes dehydrated.
• D. Switch to soy-based formula permanently.

Correct answer: A

Rationale: In the case of acute gastroenteritis in a 2-month-old infant who is bottle feeding, the nurse should recommend offering Pedialyte between formula feedings. This helps prevent dehydration and ensures that the infant receives essential electrolytes and fluids to aid in recovery. Pedialyte is specifically formulated to help replace lost fluids and electrolytes due to vomiting and diarrhea, making it a suitable choice for infants with gastroenteritis. Choice B is incorrect because infants with acute gastroenteritis should be fed more frequently to prevent dehydration. Choice C is incorrect as apple juice is not recommended for infants with gastroenteritis; Pedialyte or oral rehydration solutions are preferred. Choice D is incorrect because switching to soy-based formula permanently is not necessary for managing acute gastroenteritis; Pedialyte and continuing with the current formula are more appropriate.

5. Which statement is not a principle of family-centered care?

• A. Respect family autonomy
• B. Provide flexible services
• C. Collaborate with family members
• D. Set strict rules for families to follow

Correct answer: D

Rationale: Family-centered care focuses on respecting family autonomy, providing flexible services, and collaborating with family members to ensure individualized care. Imposing strict rules contradicts the core principles of family-centered care, which prioritize partnership, communication, and shared decision-making between healthcare providers and families. Therefore, setting strict rules for families to follow goes against the collaborative and individualized nature of family-centered care, making it the statement that is not a principle of this approach.
