Nursing Elites

1. 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.

2. After corrective surgery for hypertrophic pyloric stenosis (HPS), what should the nurse teach a parent to do immediately after a feeding to limit vomiting?

• A. Rock the infant.
• B. Place the infant in an infant seat.
• C. Place the infant flat on the right side.
• D. Keep the infant awake with sensory stimulation.

Correct answer: B

Rationale: After corrective surgery for hypertrophic pyloric stenosis (HPS), placing the infant in an infant seat is the correct action to take immediately after feeding to limit vomiting. This position helps keep the head elevated, reducing the risk of vomiting. Rocking the infant (Choice A) may agitate the stomach and increase the likelihood of vomiting. Placing the infant flat on the right side (Choice C) is not recommended as it does not encourage proper digestion and may increase the risk of vomiting. Keeping the infant awake with sensory stimulation (Choice D) does not address the positioning concern related to vomiting in this specific post-operative scenario.

3. A child is being assessed for suspected intussusception. What clinical manifestation is the nurse likely to observe?

• A. Projectile vomiting
• B. Currant jelly stools
• C. Abdominal distension
• D. Constipation

Correct answer: C

Rationale: The correct clinical manifestation that a nurse is likely to observe in a child with suspected intussusception is abdominal distension. Intussusception is a medical emergency where a part of the intestine folds into itself, causing obstruction. Abdominal distension is a common symptom due to the obstruction and the build-up of gases and fluids. While currant jelly stools (Choice B) are a classic sign of intussusception, they are typically seen in later stages of the condition and may not be present during the initial assessment. Projectile vomiting (Choice A) is more commonly associated with conditions like pyloric stenosis. Constipation (Choice D) is not a typical manifestation of intussusception; the condition usually presents with severe colicky abdominal pain and possible passage of blood and mucus in stools.

4. When administering IV fluids to a dehydrated infant, what intervention is most important at this time?

• A. Continuing the prescribed flow rate
• B. Monitoring the intravenous drop rate
• C. Calculating the total necessary intake
• D. Maintaining the fluid at body temperature

Correct answer: B

Rationale: Monitoring the intravenous drop rate is crucial when administering IV fluids to ensure that the correct amount of fluids is delivered to the dehydrated infant. Choice A assumes the initial rate is correct without ongoing assessment. Choice C, while important, does not address the immediate need for monitoring the infusion rate. Choice D, maintaining the fluid at body temperature, is essential for comfort but is not as critical as ensuring the correct fluid delivery rate. By monitoring the intravenous drop rate, healthcare providers can adjust the flow as needed to prevent overhydration or underhydration, helping to manage the infant's fluid balance effectively.

5. What is an early sign of congestive heart failure that the nurse should recognize?

• A. tachypnea
• B. bradycardia
• C. inability to sweat
• D. increased urinary output

Correct answer: A

Rationale: Tachypnea is an early sign of congestive heart failure that nurses should recognize. Tachypnea refers to rapid breathing, which can be an indication of the body's attempt to compensate for decreased cardiac output in congestive heart failure. Bradycardia (choice B) is a slow heart rate and is not typically associated with congestive heart failure. Inability to sweat (choice C) and increased urinary output (choice D) are not specific early signs of congestive heart failure and are not typically recognized as such.
