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 is functional behavior analysis?

• A. Systematic observation of behavior
• B. Standardized assessment
• C. Multiple choice examination
• D. Parent-teacher questionnaire

Correct answer: A

Rationale: Functional behavior analysis involves systematically observing behavior to understand its function and context. It focuses on identifying the antecedents and consequences that maintain or influence behavior. This systematic observation helps in determining patterns, triggers, and maintaining factors of behavior. Standardized assessments (choice B) involve using specific tools or tests to measure a person's performance or behavior but do not focus on observation. Multiple choice examinations (choice C) and parent-teacher questionnaires (choice D) are not synonymous with functional behavior analysis as they do not involve direct observation of behavior for analysis.

3. Which menu choices for a child diagnosed with renal failure and experiencing hyperkalemia indicate the need for further instruction by the nurse?

• A. Carrots and green, leafy vegetables
• B. Spaghetti and meat sauce with breadsticks
• C. Hamburger on a bun and cherry gelatin
• D. Chips, cold cuts, and canned foods

Correct answer: A

Rationale: Carrots and green, leafy vegetables are high in potassium, which should be avoided in hyperkalemia. Therefore, this choice requires further instruction by the nurse to prevent exacerbating the child's condition.

4. A healthcare professional is assessing a child who has nephrotic syndrome. Which of the following findings should the healthcare professional expect?

• A. Hypotension
• B. Hyperglycemia
• C. Facial edema
• D. Weight gain

Correct answer: D

Rationale: In nephrotic syndrome, there is increased permeability of the glomerular filtration barrier, leading to protein loss in the urine. This results in hypoalbuminemia, causing fluid retention and edema. Therefore, weight gain due to fluid retention is a common finding in children with nephrotic syndrome.

5. Which physical assessment technique should be omitted when caring for a 2-year-old child diagnosed with Wilms' tumor?

• A. Performing range-of-motion exercises on lower extremities
• B. Palpating the abdomen
• C. Assessing for bowel sounds
• D. Percussing ankle and knee reflexes

Correct answer: B

Rationale: Palpating the abdomen should be omitted when caring for a 2-year-old child diagnosed with Wilms' tumor because it could disturb the tumor and potentially cause the malignancy to spread. The other assessment techniques are safe to perform and provide valuable information about the child's condition. Range-of-motion exercises help assess mobility and joint health, assessing for bowel sounds is important to monitor gastrointestinal function, and percussing ankle and knee reflexes can help evaluate neurological responses.
