1. A nurse is caring for an infant with intractable vomiting. For what complication is it most important for the nurse to assess?
- A. Acidosis
- B. Alkalosis
- C. Hyperkalemia
- D. Hypernatremia
Correct answer: B
Rationale: When an infant experiences intractable vomiting, it can lead to the loss of stomach acids, resulting in metabolic alkalosis. Alkalosis is characterized by elevated blood pH and can lead to serious complications. Assessing for alkalosis is essential in this scenario to monitor and manage the infant's condition. Choices A, C, and D are incorrect because in this context, the primary concern is the metabolic imbalance caused by excessive vomiting, leading to alkalosis rather than acidosis, hyperkalemia, or hypernatremia.
2. An order is written for an isotonic enema for a 2-year-old child. What is the maximum amount of fluid the nurse should administer without a specific order from the healthcare provider?
- A. 100 to 150 mL
- B. 155 to 250 mL
- C. 255 to 360 mL
- D. 365 to 500 mL
Correct answer: B
Rationale: For a 2-year-old child, the maximum recommended amount of fluid for an isotonic enema is between 155 to 250 mL. This range is considered safe to prevent overdistension and potential harm to the child's rectum. Choices A, C, and D exceed the safe range for a 2-year-old child and can lead to complications such as bowel perforation or electrolyte imbalances.
3. What is an important nursing consideration for a child with a diagnosis of juvenile idiopathic arthritis (JIA) being treated with methotrexate?
- A. Monitor liver function tests regularly
- B. Encourage regular exercise
- C. Provide high-calorie snacks
- D. Encourage frequent handwashing
Correct answer: A
Rationale: Monitoring liver function tests regularly is crucial when a child with JIA is on methotrexate due to the potential hepatotoxicity associated with this medication. Methotrexate can lead to liver damage, hence monitoring helps in early detection and intervention. Encouraging regular exercise (Choice B) is generally good for children with JIA to maintain joint mobility and muscle strength, but it is not directly related to methotrexate therapy. Providing high-calorie snacks (Choice C) is not a priority consideration for a child on methotrexate. Encouraging frequent handwashing (Choice D) is important for infection control, but it is not specifically associated with methotrexate therapy in a child with JIA.
4. When teaching a class of new parents about positioning their infants during the first few weeks of life, which position is safest?
- A. On the back, lying flat
- B. On either side, lying flat
- C. Head slightly elevated on the left side
- D. Head slightly elevated on the right side
Correct answer: A
Rationale: The correct answer is A: 'On the back, lying flat'. Placing infants on their back to sleep is recommended to reduce the risk of sudden infant death syndrome (SIDS). This position helps ensure the baby's airway remains clear and reduces the likelihood of suffocation. Choices B, C, and D are not as safe as placing the infant on their back, as they may increase the risk of accidental suffocation or SIDS.
5. How is the diagnosis of Hirschsprung disease confirmed in a 1-month-old infant admitted to the pediatric unit?
- A. Colonoscopy
- B. Rectal biopsy
- C. Multiple saline enemas
- D. Fiberoptic nasoenteric tube
Correct answer: B
Rationale: Rectal biopsy is the definitive diagnostic procedure for Hirschsprung disease in infants. It confirms the absence of ganglion cells in the affected bowel segment, which is characteristic of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for confirmation as it may not provide a definitive result. Multiple saline enemas (Choice C) are utilized in the treatment of meconium ileus, a complication of cystic fibrosis, and not in the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a diagnostic tool for Hirschsprung disease; it is commonly used for gastrointestinal decompression or feeding purposes but does not confirm the diagnosis.
