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. Which characteristic best describes the fine motor skills of an infant at age 5 months?

• A. Neat pincer grasp
• B. Strong grasp reflex
• C. Builds a tower of two cubes
• D. Able to grasp object voluntarily

Correct answer: D

Rationale: By 5 months, infants develop the ability to grasp objects voluntarily, showing improved motor control. The neat pincer grasp and building towers are skills that develop later.

3. A child is admitted with renal failure. Which of these findings should the nurse expect?

• A. Decreased BUN
• B. Azotemia and oliguria
• C. Increased glomerular filtration rate (GFR)
• D. Polyuria and elevated creatinine clearance

Correct answer: B

Rationale: Azotemia (elevated BUN and creatinine) and oliguria (reduced urine output) are classic signs of renal failure, indicating impaired kidney function. In renal failure, the kidneys are unable to effectively filter waste products, leading to an increase in BUN and creatinine levels in the blood. Additionally, oliguria occurs due to decreased kidney function. Increased GFR (Choice C) is not expected in renal failure as it signifies improved kidney function, which is not the case in renal failure. Polyuria and elevated creatinine clearance (Choice D) are not typical findings in renal failure. Polyuria is more commonly associated with conditions like diabetes insipidus, while elevated creatinine clearance would indicate increased kidney function, which is contrary to the impaired function seen in renal failure.

4. Identification and treatment of cryptorchid testes should be done by age 2 years. What is an important consideration?

• A. Medical therapy is not effective after this age.
• B. Treatment is necessary to maintain the ability to be fertile when older.
• C. The younger child can tolerate the extensive surgery needed.
• D. Sexual reassignment may be necessary if treatment is not successful.

Correct answer: B

Rationale: Early treatment of cryptorchidism is essential to preserve fertility and prevent complications such as testicular cancer. Surgery is usually well-tolerated, and sexual reassignment is not typically related to this condition.

5. Which assessment findings should the nurse expect in a child with sickle cell anemia experiencing an acute vaso-occlusive crisis?

• A. Circulatory collapse, hypovolemia
• B. Cardiomegaly, systolic murmur
• C. Hepatomegaly, intrahepatic cholestasis
• D. Painful swelling of joints in hands and feet, tissue engorgement

Correct answer: D

Rationale: The correct answer is D. Vaso-occlusive crises in sickle cell anemia are characterized by painful swelling of the joints in the hands and feet (hand-foot syndrome) and tissue engorgement due to the obstruction of blood flow by sickled cells. Choices A, B, and C are incorrect because circulatory collapse, hypovolemia, cardiomegaly, systolic murmur, hepatomegaly, and intrahepatic cholestasis are not typically associated with an acute vaso-occlusive crisis in sickle cell anemia.
