1. Which congenital heart defect causes a "boot-shaped" heart on a chest x-ray?

• A. Tetralogy of Fallot
• B. Coarctation of the aorta
• C. Transposition of the great arteries
• D. Ventricular septal defect

Correct answer: A

Rationale: The correct answer is A: Tetralogy of Fallot. Tetralogy of Fallot, a congenital heart defect with four distinct abnormalities, often presents with a "boot-shaped" heart on chest x-ray due to right ventricular hypertrophy. This characteristic finding is due to the specific combination of defects in this condition. Coarctation of the aorta (choice B), Transposition of the great arteries (choice C), and Ventricular septal defect (choice D) do not typically result in a "boot-shaped" heart on a chest x-ray like Tetralogy of Fallot does.

2. What is the recommended method to assess hydration status in infants?

• A. Capillary refill time
• B. Skin turgor
• C. Urine output
• D. Mucous membranes

Correct answer: C

Rationale: The correct answer is C: Urine output. Assessing urine output is a recommended method to determine hydration status in infants. Adequate urine output indicates good hydration, while decreased urine output may suggest dehydration. Capillary refill time (Choice A) is more indicative of circulatory status rather than hydration. Skin turgor (Choice B) is a useful assessment in adults but can be less reliable in infants. Checking mucous membranes (Choice D) can provide some information on hydration, but it is not as reliable as assessing urine output in infants.

3. A child who has just had definitive repair of a high rectal malformation is to be discharged. What should the nurse address in the discharge preparation of this family?

• A. Safe administration of daily enemas
• B. Necessity of firm stools to keep suture line clean
• C. Bowel training beginning as soon as the child returns home
• D. Changes in stooling patterns to report to the practitioner

Correct answer: D

Rationale: Postoperative care should focus on monitoring changes in stooling patterns, which could indicate complications such as stenosis or obstruction. It is crucial to educate the family on the importance of promptly reporting any changes in stooling patterns to the healthcare provider. Options A and B are not recommended unless specifically ordered by the physician as they can potentially cause harm or discomfort postoperatively. Option C may not be appropriate immediately after surgery and should be guided by the healthcare provider's recommendations.

4. When transitioning from intravenous to oral morphine, what would the nurse anticipate regarding the oral dose in comparison to the intravenous dose to achieve equianalgesia?

• A. Same as the intravenous dose
• B. Greater than the intravenous dose
• C. One half of the intravenous dose
• D. One fourth of the intravenous dose

Correct answer: B

Rationale: When switching from intravenous to oral morphine, a higher oral dose is required to achieve equianalgesia due to significant metabolism from the first-pass effect. Choosing the same oral dose as the intravenous dose would provide less pain relief. Opting for a dose greater than the intravenous dose is necessary to achieve the same analgesic effect. Therefore, options A, C, and D are incorrect.

5. In terms of gross motor development, what should the nurse expect an infant age 5 months to do?

• A. Sit erect without support
• B. Roll from the back to the abdomen
• C. Turn from the abdomen to the back
• D. Move from a prone to a sitting position

Correct answer: C

Rationale: At 5 months, infants typically can turn from their abdomen to their back. Rolling from back to abdomen and sitting erect without support occur later.
