Nursing Elites

1. A healthcare provider is assessing a 3-month-old infant with suspected pyloric stenosis. What clinical manifestation is the healthcare provider likely to observe?

• A. Projectile vomiting
• B. Diarrhea
• C. Constipation
• D. Abdominal distension

Correct answer: A

Rationale: Projectile vomiting is a classic clinical manifestation of pyloric stenosis in infants. This occurs due to the narrowing of the pyloric sphincter, leading to the forceful expulsion of gastric contents in a projectile manner. Diarrhea (choice B) is not typically associated with pyloric stenosis. Constipation (choice C) is also not a common symptom of this condition. Abdominal distension (choice D) may occur in pyloric stenosis but is not as specific or characteristic as projectile vomiting in diagnosing this condition.

2. The nurse is teaching a group of students about myelination in a child. Which statement by the students indicates that the teaching was successful?

• A. Myelination continues into adolescence and beyond.
• B. The process occurs in a cephalocaudal (head-to-toe) pattern.
• C. Myelination decreases the speed of nerve impulses.
• D. Myelination decreases the specificity of nerve impulses.

Correct answer: B

Rationale: The correct answer is B. Myelination occurs in a cephalocaudal (head-to-toe) pattern, improving nerve function progressively. Choice A is incorrect as myelination continues into adolescence and beyond, not just during childhood. Choice C is incorrect because myelination actually increases the speed of nerve impulses rather than decreasing it. Choice D is incorrect as myelination enhances the specificity of nerve impulses, making them more efficient and precise rather than less specific.

3. A 1-week-old infant has been in the pediatric unit for 18 hours following placement of a spica cast. The nurse observes a respiratory rate of fewer than 24 breaths/min. No other changes are noted. Because the infant is apparently well, the nurse does not report or document the slow respiratory rate. Several hours later, the infant experiences severe respiratory distress and emergency care is necessary. What should be considered if legal action is taken?

• A. Most infants have slow respirations when they are uncomfortable.
• B. The respirations of young infants are irregular, so a drop in rate is unimportant.
• C. Vital signs that are outside the expected parameters are significant and should be documented.
• D. The respiratory tract of young infants is underdeveloped, and their respiratory rate is not significant.

Correct answer: C

Rationale: In this scenario, the correct answer is C. Any vital signs outside the expected range in an infant should be documented and reported, as they may indicate a developing condition that requires prompt attention. Choice A is incorrect because slow respirations in infants should not be dismissed without assessment and documentation. Choice B is incorrect because a drop in respiratory rate in this case was significant and should have been documented. Choice D is incorrect because even though infants have underdeveloped respiratory tracts, any abnormal respiratory rate should be taken seriously and documented for monitoring and intervention if necessary.

4. What should the nurse recommend to reduce the risk of sudden infant death syndrome (SIDS) in a 6-month-old infant?

• A. Place the infant on their back to sleep
• B. Use a pacifier during sleep
• C. Have the infant sleep on their side
• D. Keep the infant's room cool

Correct answer: A

Rationale: Placing the infant on their back to sleep is the correct recommendation to reduce the risk of sudden infant death syndrome (SIDS). This sleep position has been shown to significantly decrease the incidence of SIDS. Using a pacifier during sleep (Choice B) can also help reduce the risk, but it is secondary to the back sleeping position. Having the infant sleep on their side (Choice C) is not recommended, as it increases the risk of SIDS. Keeping the infant's room cool (Choice D) may provide a comfortable sleeping environment but does not directly reduce the risk of SIDS.

5. A 3-year-old child with a history of frequent respiratory infections is being evaluated for cystic fibrosis. What diagnostic test should the nurse anticipate will be ordered?

• A. Chest X-ray
• B. Sweat chloride test
• C. Pulmonary function test
• D. Sputum culture

Correct answer: B

Rationale: The correct answer is the sweat chloride test. This test is crucial in diagnosing cystic fibrosis as it measures the amount of chloride in sweat, which is typically elevated in individuals with cystic fibrosis. A chest X-ray (Choice A) may show characteristic findings like hyperinflation or bronchiectasis, but it is not a definitive diagnostic test for cystic fibrosis. Pulmonary function tests (Choice C) may help assess lung function but are not specific for cystic fibrosis. Sputum culture (Choice D) may be used to identify specific pathogens causing respiratory infections but is not a primary diagnostic test for cystic fibrosis.
