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 mother of a 3-month-old breastfed infant asks about giving her baby water because it is summer and very warm. What should the nurse tell her?

• A. Fluids in addition to breast milk are not needed.
• B. Water should be given if the infant seems to nurse longer than usual.
• C. Clear juices are better than water to promote adequate fluid intake.
• D. Water once or twice a day will make up for losses resulting from environmental temperature.

Correct answer: A

Rationale: Breast milk provides adequate hydration, even in warm weather, so additional fluids like water are not necessary and can interfere with breastfeeding.

3. The mother of a child with cognitive impairment calls the nurse because her son has been gagging and drooling all morning. The nurse suspects foreign body ingestion. What physiologic occurrence is most likely responsible for the presenting signs?

• A. Gastrointestinal perforation may have occurred.
• B. The object may have been aspirated.
• C. The object may be lodged in the esophagus.
• D. The object may be embedded in the stomach wall.

Correct answer: C

Rationale: The symptoms of gagging and drooling suggest that the foreign object is likely lodged in the esophagus. This can cause significant discomfort and potential complications, requiring immediate medical evaluation.

4. Using knowledge of child development, what approach is best when preparing a toddler for a procedure?

• A. Avoid asking the child to make choices.
• B. Plan for a teaching session to last about 20 minutes.
• C. Demonstrate on a doll how the procedure will be done.
• D. Show the necessary equipment without allowing child to handle it.

Correct answer: C

Rationale: Demonstrating on a doll helps the toddler understand what will happen in a non-threatening way, making the procedure less intimidating. Long teaching sessions or avoiding choices can increase anxiety.

5. The mother of an infant diagnosed with bronchiolitis asks the nurse what causes the disease. How should the nurse respond?

• A. Respiratory syncytial virus (RSV)
• B. Haemophilus influenzae
• C. Parainfluenza
• D. Rotavirus

Correct answer: A

Rationale: The correct answer is A: Respiratory syncytial virus (RSV). RSV is the most common cause of bronchiolitis, especially in infants. Bronchiolitis is characterized by inflammation of the small airways in the lungs. Choice B, Haemophilus influenzae, is a bacterium that can cause respiratory infections but is not the primary cause of bronchiolitis. Choice C, Parainfluenza, is a common viral infection that can cause croup and other respiratory illnesses but is not the main cause of bronchiolitis. Choice D, Rotavirus, is a virus that primarily affects the gastrointestinal system, causing diarrhea and vomiting, and is not associated with bronchiolitis.
