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. Which of the following is a key feature of the diagnosis of ASD according to the DSM V?

• A. Unusual responses to sensory input
• B. Social isolation
• C. Repetitive behaviors
• D. Delayed motor development

Correct answer: A

Rationale: In the DSM V, one of the key diagnostic criteria for Autism Spectrum Disorder (ASD) is unusual responses to sensory input. These atypical responses can include hypersensitivity or hyposensitivity to sensory stimuli, such as sound, touch, taste, or smell. These sensory processing differences are important in the diagnosis of ASD because they can significantly impact an individual's daily functioning and behavior. Social isolation and repetitive behaviors are associated features of ASD but are not the key diagnostic criteria according to the DSM V. Delayed motor development may be observed in some individuals with ASD, but it is not a key feature used for diagnosis in the DSM V.

3. Which law provides for infants and toddlers aged 0-2 who are in need of comprehensive early intervention services?

• A. IDEA- Part B
• B. IDEA- Part A
• C. IFSP
• D. IDEA- Part C

Correct answer: D

Rationale: The correct answer is D, IDEA Part C. IDEA Part C specifically focuses on providing early intervention services to infants and toddlers with disabilities. This law ensures that children aged 0-2 receive the necessary support and services to aid in their development and address any disabilities or developmental delays early on. Choices A, B, and C are incorrect. IDEA Part B pertains to services for school-aged children with disabilities, IDEA Part A does not exist in the context of the Individuals with Disabilities Education Act (IDEA), and IFSP stands for Individualized Family Service Plan, which is a document outlining services for children from birth to age 3 who are experiencing developmental delays or disabilities, but it is not a law in itself.

4. A nurse is planning care for a school-age child who has thrombocytopenia. Which of the following interventions should the nurse include in the plan?

• A. Administer aspirin as needed for fever.
• B. Avoid venipunctures whenever possible.
• C. Encourage the child to participate in contact sports.
• D. Administer ibuprofen for pain.

Correct answer: B

Rationale: The correct answer is B: 'Avoid venipunctures whenever possible.' Thrombocytopenia is a condition characterized by a low platelet count, which can lead to an increased risk of bleeding. Venipunctures can cause bleeding in these patients; therefore, they should be avoided whenever possible. Choice A is incorrect because aspirin should be avoided in patients with thrombocytopenia as it can further increase the risk of bleeding due to its antiplatelet effects. Choice C is incorrect because participating in contact sports can also increase the risk of injury and bleeding in a child with thrombocytopenia. Choice D is incorrect as ibuprofen, like aspirin, can also increase the risk of bleeding and should be avoided in these patients.

5. A nurse is teaching a parent of a child who has asthma. Which of the following instructions should the nurse include?

• A. Use a peak flow meter daily.
• B. Administer the medication with meals.
• C. Provide a low-carbohydrate diet.
• D. Limit exposure to cold air.

Correct answer: A

Rationale: The nurse should instruct the parent to use a peak flow meter daily to monitor the child�s respiratory status and detect early signs of an asthma attack.
