Nursing Elites

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. What should be taught to the child and parents about using a peak flow meter for a child diagnosed with asthma?

• A. Use the device before taking medication
• B. Use the device during asthma attacks
• C. Record the best of three attempts
• D. Use the device after eating

Correct answer: C

Rationale: The correct answer is to 'Record the best of three attempts.' This method provides an accurate measure of peak expiratory flow using a peak flow meter. By taking the best of three attempts, the child and parents can obtain a more reliable assessment of the child's lung function. Choices A, B, and D are incorrect because using the device before taking medication, during asthma attacks, or after eating does not ensure an accurate measurement of peak flow, which is essential for managing asthma effectively. Monitoring peak flow regularly and accurately can help in adjusting asthma treatment plans and assessing response to medications.

3. During the health assessment of a school-age child, on which problem would the nurse focus more attention based on the child's developmental level?

• A. Infections
• B. Poisonings
• C. Risk-taking behaviors
• D. Accidents and injuries

Correct answer: D

Rationale: During the school-age years, children are more physically active and curious, which increases their risk of accidents and injuries. This developmental stage is characterized by increased exploration and engagement in physical activities. While infections and poisonings are important health concerns, school-age children are more likely to be affected by accidents and injuries due to their active nature. Risk-taking behaviors may become more prevalent in adolescence rather than during the school-age period, making it a less likely focus for the nurse during the health assessment of a school-age child.

4. 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.

5. After a child returns from surgery for a tracheostomy, what is the priority nursing action?

• A. Suctioning the tracheostomy tube
• B. Changing the tracheostomy dressing
• C. Monitoring respiratory status
• D. Ensuring the tracheostomy ties are secure

Correct answer: A

Rationale: The priority nursing action after a tracheostomy surgery is to suction the tracheostomy tube. Suctioning helps maintain a clear airway and prevent complications such as airway obstruction or respiratory distress. While monitoring respiratory status is important, suctioning takes precedence immediately post-surgery to ensure adequate air exchange. Changing the tracheostomy dressing and ensuring tracheostomy ties are secure are also essential tasks but are secondary to the critical need for airway maintenance through suctioning.
