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. During an assessment, a healthcare professional is evaluating an infant with pneumonia. Which of the following findings should be the priority for the healthcare professional to report to the provider?

• A. Nasal flaring
• B. WBC count of 11,300
• C. Diarrhea
• D. Abdominal distension

Correct answer: A

Rationale: When assessing an infant with pneumonia, the priority finding to report to the provider is nasal flaring. Nasal flaring indicates acute respiratory distress, which can be a life-threatening condition requiring immediate intervention. Monitoring and addressing respiratory distress take precedence over other symptoms or laboratory results in this situation.

3. A child is being cared for by a nurse and has rheumatic fever. Which of the following actions should the nurse plan to take?

• A. Administer aspirin to the child as prescribed based on the healthcare provider's instructions.
• B. Encourage adequate fluid intake for the child.
• C. Elevate the child's joints and provide warm compresses.
• D. Monitor the child's heart rate for dysrhythmias.

Correct answer: D

Rationale: Rheumatic fever can lead to cardiac complications, such as dysrhythmias. Therefore, it is essential for the nurse to monitor the child's heart rate closely for any signs of dysrhythmias. This will help in early identification and prompt management of potential cardiac issues associated with rheumatic fever. Choices A, B, and C are not the priority actions in this scenario. While aspirin may be used in the treatment of rheumatic fever, monitoring for cardiac complications takes precedence. Encouraging fluid intake and providing warm compresses are helpful interventions but do not directly address the cardiac risks associated with rheumatic fever.

4. What is the corrected age of a child born at 30 weeks gestation on May 2, 2014, who is being tested on August 5, 2014?

• A. 3 months
• B. 2 weeks
• C. 2.6 months
• D. 4 weeks

Correct answer: B

Rationale: To calculate the corrected age of a premature child, you need to adjust for the weeks of prematurity. In this case, the child was born at 30 weeks gestation. From May 2, 2014, to August 5, 2014, is a span of 14 weeks. Subtracting the 30 weeks of gestation from the total time passed (14 weeks) gives the corrected age, which is 14 - 30 = -16 weeks. Since negative weeks are not relevant here, the corrected age is 0 weeks, which is equivalent to 2 weeks. Choice A is incorrect because 3 months is not the correct adjustment for the given scenario. Choice C is incorrect as it provides a fractional value for age, which is not practical in this context. Choice D is incorrect as 4 weeks does not account for the weeks of prematurity.

5. When developing a home program for self-care, which approach is the most effective?

• A. Require the parent to practice the steps regularly and track progress.
• B. Introduce new home programs weekly with clear instructions for the parent to follow.
• C. List all the steps and have the parent teach them to the child without practicing.
• D. Practice the new steps until the child is ready to independently perform them at home.

Correct answer: D

Rationale: The most effective approach when developing a home program for self-care is to practice the new steps with the child until they are capable of independently carrying them out at home. This method ensures that the child has mastered the skills before transitioning to independent implementation. It is essential for the child's success in self-care activities and promotes their autonomy and confidence. Requiring the parent to practice the steps regularly and track progress, introducing new programs weekly, or having the parent teach the steps without practice may not be as beneficial in fostering the child's independence and skill acquisition.
