1. The nurse is caring for a child with acute renal failure. What laboratory findings should the nurse expect to find? (Select all that apply.)

A. Hyponatremia
B. Hyperkalemia
C. All are applicable
D. Elevated blood urea nitrogen level

Correct answer: C

Rationale: In acute renal failure, laboratory findings typically include hyperkalemia, hyponatremia, and elevated blood urea nitrogen (BUN) levels due to the kidneys' inability to excrete waste and balance electrolytes. Metabolic alkalosis is less common, with metabolic acidosis being more typical.

2. At which age can most infants sit steadily unsupported?

A. 4 months
B. 6 months
C. 8 months
D. 12 months

Correct answer: C

Rationale: Most infants can sit steadily without support by 8 months, indicating advanced gross motor skill development.

3. At what stage can infants raise their heads and gain control of their trunks before walking due to which directional pattern of development?

A. Cephalocaudal
B. Anterior to posterior
C. Proximodistal
D. Normal growth curve charts

Correct answer: A

Rationale: The correct answer is A: Cephalocaudal. The cephalocaudal pattern of development means that growth and motor control proceed from the head downward through the body. This explains why infants can raise their heads before they can sit and gain control of their trunks before walking. Choices B, C, and D are incorrect. Anterior to posterior refers to development from the front to the back, while proximodistal refers to development from the center of the body outward. Normal growth curve charts are used to track physical growth over time and are not directly related to the directional pattern of development in infants.

4. 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.

5. A school-age child with cancer is being prepared for a procedure. The child says, “I have had one of these before. They hurt.” The nurse bases her response on what knowledge related to pain in this patient?

A. Often misrepresent experiencing pain
B. Tolerate pain better than adults
C. Become accustomed to painful procedures
D. Commonly experience treatment-related moderate to severe pain when they have cancer

Correct answer: D

Rationale: The correct answer is D. Pain is frequently reported by children with cancer, with around 84% experiencing it. Most children report moderate to severe pain, with about half finding it highly distressing. There is no evidence to suggest that children often misrepresent their pain experiences. Pain tolerance is not solely based on age but is a complex phenomenon. Children do not become accustomed to painful procedures, as each experience of pain is unique.
