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. Clear the immediate area around the child of hazardous objects
• B.
• C. assist the child to a side-lying position on the floor
• D. apply an oxygen mask to the child

Correct answer: C

Rationale: The greatest risk to this child is aspiration, occlusion of the airway, and bodily injury from falling out of the chair. The nurse should ease the child down to the floor in a side-lying position immediately.

3. A child is being assessed for Kawasaki disease. Which of the following findings should be expected?

• A. Decreased heart rate
• B. Dry, scaly skin
• C. Fever unresponsive to antipyretics
• D. Nontender cervical lymphadenopathy

Correct answer: C

Rationale: In Kawasaki disease, a child typically presents with a fever that is unresponsive to antipyretics because the disease is characterized by systemic inflammation. The persistent fever is a hallmark feature of the disease and can last for more than five days despite treatment with antipyretics.

4. The healthcare provider discussed strategies with a parent to prevent a recurrence of urinary tract infection in the child. Which statement made by the parent indicates a need for further teaching?

• A. My daughter should wash and wipe the perineal area from front to back.
• B. I am only going to have my daughter wear cotton underwear.
• C. It is acceptable to take frequent bubble baths.
• D. She needs to drink lots of fluids and void frequently.

Correct answer: C

Rationale: The statement 'It is acceptable to take frequent bubble baths' indicates a need for further teaching. Oils in bubble bath and similar products can irritate the urethra, potentially leading to recurrent urinary tract infections. The other choices are correct: wiping from front to back helps prevent the spread of bacteria, wearing cotton underwear promotes breathability and reduces moisture, and drinking fluids and voiding frequently help flush out bacteria.

5. A preschool-age child is admitted to the hospital with acute postinfectious glomerulonephritis (APIGN). Which is the priority nursing diagnosis for this child?

• A. Risk for Injury related to hypertension.
• B. Altered Growth and Development related to chronic disease.
• C. Risk for Infection related to hypertension.
• D. Fluid Volume Excess related to decreased plasma filtration.

Correct answer: A

Rationale: The priority nursing diagnosis for a preschool-age child with acute postinfectious glomerulonephritis (APIGN) is 'Risk for Injury related to hypertension' due to the potential complications such as hypertensive encephalopathy. Hypertension poses an immediate threat to the child's well-being, making it crucial to address the risk for injury associated with elevated blood pressure as the top priority.
