1. 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.

2. The parents of a child who is scheduled for open-heart surgery ask why their child must be subjected to chest tubes after surgery. What should the nurse consider before responding in language the parents will understand?

• A. They will increase tidal volumes.
• B. Drainage of air and fluid will be facilitated.
• C. They will maintain positive intrapleural pressure.
• D. Pressure on the pericardium and chest wall will be regulated.

Correct answer: B

Rationale: Chest tubes are used to drain air and fluid from the chest cavity to prevent complications such as pneumothorax or cardiac tamponade after surgery. Choice A is incorrect as chest tubes are not used to increase tidal volumes. Choice C is incorrect as chest tubes do not maintain positive intrapleural pressure; instead, they assist in removing excess air or fluid. Choice D is incorrect as chest tubes do not regulate pressure on the pericardium and chest wall; they primarily aid in drainage.

3. What should be included in the nursing plan of care for a 6-month-old infant admitted to the pediatric unit with a diagnosis of respiratory syncytial virus (RSV)?

• A. Place the infant in a warm, dry environment.
• B. Allow parents and siblings to visit.
• C. Maintain standard and contact precautions.
• D. Administer prescribed antibiotics immediately.

Correct answer: C

Rationale: The correct answer is C: Maintain standard and contact precautions. RSV is highly contagious, primarily spread through respiratory secretions. Therefore, it is crucial to implement infection control measures such as standard and contact precautions to prevent the spread of the virus to other patients, staff, and visitors. Choice A is incorrect because warmth and dryness are not specific interventions for RSV; the focus should be on infection control. Choice B may increase the risk of exposing others to RSV, so limiting visitors is recommended. Choice D is unnecessary because RSV is a viral infection, and antibiotics are not effective against viruses.

4. A child with sickle cell anemia develops severe chest pain, fever, a cough, and dyspnea. What should the nurse do first?

• A. Administer 100% oxygen to relieve hypoxia
• B. Administer pain medication to relieve symptoms
• C. Notify the practitioner because chest syndrome is suspected
• D. Notify the practitioner because the child may be having a stroke

Correct answer: C

Rationale: The correct action to take first when a child with sickle cell anemia presents with severe chest pain, fever, cough, and dyspnea is to notify the practitioner because acute chest syndrome is suspected. This condition is a medical emergency requiring prompt intervention. Administering oxygen or pain medication may be necessary interventions but should not precede notifying the practitioner. Stroke is not typically associated with these symptoms in sickle cell anemia.

5. Which cardiac defects are associated with tetralogy of Fallot?

• A. Right ventricular hypertrophy, atrial and ventricular defects, and mitral valve stenosis
• B. Origin of the aorta from the right ventricle and of the pulmonary artery from the left ventricle
• C. Right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta
• D. Altered connection between the pulmonary artery and the aorta, right ventricular hypertrophy, and an atrial septal defect

Correct answer: C

Rationale: Tetralogy of Fallot is characterized by a combination of four specific cardiac defects: right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta. Choice A is incorrect as it includes mitral valve stenosis, which is not typically part of tetralogy of Fallot. Choice B describes transposition of the great arteries rather than tetralogy of Fallot. Choice D includes an atrial septal defect, which is not part of the classic presentation of tetralogy of Fallot.
