1. What condition is the most common cause of acute renal failure in children?

• A. Pyelonephritis
• B. Tubular destruction
• C. Severe dehydration
• D. Upper tract obstruction

Correct answer: C

Rationale: Severe dehydration is the most common cause of acute renal failure in children, as it leads to prerenal azotemia, which can progress to renal failure if not corrected. Other causes like pyelonephritis and tubular destruction are less common and usually secondary to other conditions.

2. The nurse is caring for a child receiving chemotherapy with the following orders: Zantac 70 mg IV in normal saline 30 mL to infuse over 30 minutes. The nurse should set the infusion pump to deliver how many mL/hour?

• A. 60 mL/hour
• B. 45 mL/hour
• C. 30 mL/hour
• D. 15 mL/hour

Correct answer: A

Rationale: The correct answer is A: 60 mL/hour. The total volume to be infused is 30 mL over 30 minutes. To calculate the infusion rate in mL/hour, divide the total volume by the total time in hours. In this case, 30 mL / 0.5 hours = 60 mL/hour. Choice B, 45 mL/hour, is incorrect as it does not correspond to the calculated infusion rate. Choices C and D, 30 mL/hour and 15 mL/hour respectively, are also incorrect based on the calculation.

3. What is the most common piece of medical equipment that can transmit harmful microorganisms among patients?

• A. Thermometer
• B. Stethoscope
• C. Injection needle
• D. Disposable gloves

Correct answer: B

Rationale: The correct answer is B: Stethoscope. A stethoscope is commonly used between patients, and if not correctly disinfected, it can be a dangerous source of spreading microorganisms. Thermometers typically have barriers to prevent this type of transmission. Injection needles are discarded immediately after use and not reused, making them an unlikely source of transmission. Similarly, disposable gloves are not reused, so they are also not a common source of harmful microorganism transmission.

4. Which condition is most commonly associated with a 'sunset sign' in infants?

• A. Hydrocephalus
• B. Meningitis
• C. Cerebral palsy
• D. Encephalitis

Correct answer: A

Rationale: The 'sunset sign,' characterized by downward-driven eyes, is most commonly associated with hydrocephalus. This condition causes increased intracranial pressure, leading to the eyes appearing to be forced downward. Meningitis (choice B) typically presents with symptoms such as fever, headache, and a stiff neck, but not the 'sunset sign.' Cerebral palsy (choice C) is a group of disorders affecting movement and muscle coordination, not directly related to the 'sunset sign.' Encephalitis (choice D) is inflammation of the brain, which can cause symptoms like fever, headache, and confusion, but not the specific downward eye gaze seen in the 'sunset sign.'

5. For minimal change nephrotic syndrome (MCNS), prednisone is effective when what occurs?

• A. Appetite increases and blood pressure is normal
• B. Urinary tract infection is gone and edema subsides
• C. Generalized edema subsides and blood pressure is normal
• D. Diuresis occurs as urinary protein excretion diminishes

Correct answer: D

Rationale: The effectiveness of prednisone in treating MCNS is indicated by diuresis and a decrease in urinary protein excretion. Subsidence of generalized edema is also a positive sign, but the key indicator is the reduction in proteinuria, which is achieved through diuresis.
