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. A caregiver is learning about administering digoxin to a toddler. Which statement by the caregiver indicates an understanding of the teaching?

• A. I will mix the medication with a small amount of juice.
• B. I will give the medication with meals.
• C. I will give a second dose if my child vomits.
• D. I will give my child water after giving the medication.

Correct answer: D

Rationale: The correct statement is D because giving the child water after administering digoxin helps ensure the medication is swallowed properly. Mixing the medication with juice (choice A) may affect its absorption. Giving the medication with meals (choice B) may interfere with its effectiveness. Administering a second dose if the child vomits (choice C) is not recommended as it may lead to an overdose.

3. Which assessment data would cause suspicion that a 3-year-old child has Hirschsprung disease?

• A. Clay-colored stools and dark urine
• B. History of early passage of meconium in the newborn period
• C. History of chronic, progressive constipation and failure to gain weight
• D. Continual bouts of foul-smelling diarrhea

Correct answer: C

Rationale: Hirschsprung disease is characterized by chronic, progressive constipation and failure to gain weight. These symptoms are indicative of the disorder due to the absence of ganglion cells in the distal colon, leading to impaired motility and obstruction.

4. Which of the following is a common issue experienced by families of children with ASD?

• A. Financial limitations
• B. Social isolation
• C. Difficulty accessing needed services
• D. Difficulty obtaining early diagnosis

Correct answer: C

Rationale: Families of children with ASD commonly experience challenges in accessing needed services. This can include difficulties in obtaining appropriate therapies, educational support, and specialized interventions. While financial limitations and social isolation are also significant issues faced by these families, the primary concern often revolves around the challenges in accessing essential services for their children.

5. Which standardized test would be most appropriate for assessing the motor development of a 2-month-old infant in a high-risk clinic?

• A. Peabody Developmental Motor Scale (PDMS-2)
• B. Bruininks-Oseretsky Test of Motor Proficiency (BOT-2)
• C. Pediatric Evaluation of Disability Index (PEDI)
• D. School Assessment of Motor and Process Skills (School-AMPS)

Correct answer: A

Rationale: The Peabody Developmental Motor Scale (PDMS-2) is specifically designed to assess the motor development of infants and young children, making it the most appropriate choice for evaluating a 2-month-old infant in a high-risk clinic setting.
