1. Which pediatric disorder is associated with a 'boot-shaped' heart on a chest x-ray?

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

Correct answer: A

Rationale: The correct answer is A: Tetralogy of Fallot. Tetralogy of Fallot is often associated with a 'boot-shaped' heart appearance on a chest x-ray due to the characteristic heart anatomy in this condition. This appearance is caused by the combination of pulmonary stenosis, overriding aorta, ventricular septal defect, and right ventricular hypertrophy. Choice B, Transposition of the great arteries, is incorrect because it presents with a 'egg-on-a-string' appearance on x-ray due to the abnormal position of the aorta and pulmonary artery. Choice C, Coarctation of the aorta, typically presents with rib notching on x-ray. Choice D, Ventricular septal defect, does not produce the 'boot-shaped' heart appearance seen in Tetralogy of Fallot.

2. The nurse on a pediatric unit is writing guidelines for age-specific preparation of children for procedures based on developmental characteristics. What guideline is accurate?

• A. Inform toddlers about an upcoming procedure 2 hours before the procedure is to be performed.
• B. Inform school-age children about an upcoming procedure immediately before the procedure is scheduled to occur.
• C. Discourage parent presence during procedures on infants and toddlers.
• D. Use simple diagrams of anatomy and physiology to explain a procedure to a school-age child.

Correct answer: D

Rationale: Using simple diagrams helps school-age children understand what to expect in a procedure, catering to their developmental level and reducing anxiety. Informing toddlers too early can increase anxiety, and parents' presence is generally comforting, not discouraging.

3. What is the most appropriate action for a child with epistaxis?

• A. Have the child lie flat
• B. Pinch the nose and lean forward
• C. Apply a warm compress to the nose
• D. Encourage deep breathing

Correct answer: B

Rationale: The most appropriate action for a child with epistaxis is to pinch the nose and lean forward. This technique helps stop the bleeding and prevent aspiration of blood. By applying pressure to the bleeding vessels and allowing the blood to drain out of the nostrils instead of being swallowed, the risk of nausea and airway obstruction is reduced. Having the child lie flat (Choice A) may lead to blood flowing down the throat, causing potential choking. Applying a warm compress (Choice C) is not typically recommended for epistaxis as cold compresses are more effective. Encouraging deep breathing (Choice D) is not directly related to managing epistaxis.

4. Which family theory explains how families react to stressful events and suggests factors that promote adaptation to these events?

• A. Interactional theory
• B. Family stress theory
• C. Erikson's psychosocial theory
• D. Developmental systems theory

Correct answer: B

Rationale: Family stress theory explains how families respond to stress and identifies factors that help families adapt to and manage stressful events effectively.

5. Evidence-based practice (EBP), a decision-making model, is best described as which?

• A. Using information in textbooks to guide care
• B. Combining knowledge with clinical experience and intuition
• C. Using a professional code of ethics as a means for decision-making
• D. Gathering all evidence that applies to the child’s health and family situation

Correct answer: D

Rationale: Evidence-based practice involves gathering and integrating all relevant evidence to guide clinical decision-making, ensuring that care is based on the best available research.
