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. When picked up by a parent or the nurse, an 8-month-old infant screams and seems to be in pain. After observing this behavior, what should the nurse discuss with the parent?

• A. Accidents and the importance of accident prevention
• B. Limiting playtime with other children in the family
• C. Any other behaviors that the parent may have noticed
• D. Food and appropriate vitamins for infants

Correct answer: C

Rationale: Discussing any other observed behaviors can help identify patterns or potential issues, which is crucial for assessing the infant's overall well-being. Option A about accidents and prevention is not pertinent to the situation described. Option B regarding playtime with other children does not address the infant's behavior and potential causes. Option D about food and vitamins is not relevant to the presented scenario and the observed behavior of the infant.

3. After a discussion with the health care provider, the parents of an infant with patent ductus arteriosus (PDA) ask the nurse to explain once again what PDA is. How should the nurse respond?

• A. The diameter of the aorta is enlarged.
• B. The wall between the right and left ventricles is open.
• C. It is a narrowing of the entrance to the pulmonary artery.
• D. It is a connection between the pulmonary artery and the aorta.

Correct answer: D

Rationale: The correct answer is D: 'It is a connection between the pulmonary artery and the aorta.' Patent ductus arteriosus (PDA) is an abnormal connection between the pulmonary artery and the aorta, which normally closes after birth. Choices A, B, and C describe different cardiac conditions and do not accurately define PDA. Choice A is incorrect because PDA does not involve the diameter of the aorta being enlarged. Choice B is incorrect because PDA does not involve the wall between the right and left ventricles being open. Choice C is incorrect because PDA is not a narrowing of the entrance to the pulmonary artery.

4. What is an important nursing responsibility when a dysrhythmia is suspected?

• A. order an immediate electrocardiogram
• B. count the radial pulse every 1 minute for five times
• C. count the apical pulse for 1 full minute, and compare the rate with the radial pulse rate
• D. have someone else take the radial pulse simultaneously with the apical pulse

Correct answer: C

Rationale: When a dysrhythmia is suspected, an important nursing responsibility is to count the apical pulse for 1 full minute and then compare this rate with the radial pulse rate. This method helps in identifying dysrhythmias as it allows for a direct comparison of the heart's rhythm at two different pulse points. Ordering an immediate electrocardiogram (Choice A) may be necessary but should not be the first step. Counting the radial pulse multiple times (Choice B) is not as accurate as comparing rates directly. Having someone else take the radial pulse simultaneously (Choice D) may introduce errors and inconsistencies in the measurement.

5. A parent asks the nurse what to do for their child who has an earache and fever. What should the nurse suggest?

• A. Applying a warm compress to the affected ear
• B. Giving the child a cold drink
• C. Administering acetaminophen
• D. Taking the child to the emergency department

Correct answer: A

Rationale: Applying a warm compress to the affected ear is a recommended home remedy for earaches as it can help reduce pain and discomfort. The warmth can also help improve circulation and promote drainage if there is fluid buildup. Giving a cold drink (Choice B) is not typically beneficial for earaches and fever. Administering acetaminophen (Choice C) can help reduce fever and alleviate pain, but addressing the earache directly with a warm compress is a more targeted approach. Taking the child to the emergency department (Choice D) is not necessary for a common earache unless there are severe symptoms or complications present.
