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 healthcare provider is assessing a child with acute lymphocytic leukemia. Which of the following findings is the priority for the healthcare provider to report?

• A. Bruising
• B. Petechiae
• C. Elevated WBC count
• D. Elevated platelet count

Correct answer: B

Rationale: The priority finding to report for a child with acute lymphocytic leukemia is petechiae. Petechiae indicate a low platelet count, which increases the risk of bleeding. Therefore, the healthcare provider should promptly report petechiae to initiate appropriate interventions to prevent bleeding complications.

3. When providing teaching to the family of a school-age child with juvenile idiopathic arthritis, which instruction should the nurse include?

• A. Limit the child's movement of the large joints.
• B. Encourage the child to perform independent self-care.
• C. Provide the child with a soft mattress for sleeping.
• D. Schedule a 2-hour daily nap for the child in the afternoon.

Correct answer: B

Rationale: Encouraging the child to perform independent self-care is essential when managing juvenile idiopathic arthritis. This instruction helps minimize pain and stiffness in the child's joints while promoting mobility and independence. It is crucial for the child to learn self-management skills early to cope better with the condition in the long term.

4. A patient with Parkinson’s disease who takes levodopa/carbidopa (Sinemet) comes to the clinic for a semi-annual physical examination. Which question is the most important for that nurse to ask?

• A. Have you noticed any swelling in your feet?
• B. Are you having vivid dreams or hallucination?
• C. Have you noticed any changes in your stool?
• D. Have you had your flu vaccine?

Correct answer: B

Rationale: Patients taking levodopa/carbidopa (Sinemet) are at increased risk for the psychiatric side effects of levodopa, including visual hallucinations, vivid dreams, nightmares, and paranoid ideation. The other questions are not directly related to problems that are likely to occur with this drug.

5. A 6-year-old child with daytime enuresis complains of dysuria and urgency. What does the nurse recognize these signs and symptoms indicate?

• A. Urinary tract infection
• B. Nephrotic syndrome
• C. Acute glomerulonephritis
• D. Vesicoureteral reflux

Correct answer: A

Rationale: The signs and symptoms of dysuria and urgency in a child with daytime enuresis typically indicate a urinary tract infection (UTI). These symptoms, along with urinary frequency and pain during urination, are common manifestations of a UTI in children. Nephrotic syndrome is characterized by edema, proteinuria, hypoalbuminemia, and hyperlipidemia, rather than dysuria and urgency. Acute glomerulonephritis presents with hematuria, proteinuria, hypertension, and oliguria, not dysuria and urgency. Vesicoureteral reflux can lead to recurrent UTIs but does not directly cause dysuria and urgency.
