1. Which of the following parameters would be LEAST reliable when assessing the perfusion status of a 2-year-old child with possible shock?

• A. distal capillary refill
• B. systolic blood pressure
• C. skin color and temperature
• D. presence of peripheral pulses

Correct answer: B

Rationale: Systolic blood pressure is the least reliable parameter when assessing the perfusion status of a 2-year-old child with possible shock. In pediatric patients, especially young children, blood pressure may not decrease until significant shock has already occurred, making it a late indicator of inadequate perfusion. Depending solely on systolic blood pressure to evaluate perfusion status in this age group can lead to a delay in appropriate interventions. Distal capillary refill time, skin color, and temperature changes, and the presence of peripheral pulses are more sensitive and early indicators of perfusion status in pediatric patients. Monitoring distal capillary refill provides information on peripheral perfusion, while changes in skin color and temperature can signal circulatory compromise. Evaluating the presence or absence of peripheral pulses offers insights into vascular perfusion. These parameters offer more reliable and prompt feedback on a child's perfusion status compared to systolic blood pressure.

2. An infant is diagnosed with Hirschsprung disease. What nursing intervention is essential before surgery?

• A. Administering antibiotics
• B. Ensuring bowel rest
• C. Performing regular enemas
• D. Maintaining NPO status

Correct answer: D

Rationale: Maintaining NPO (nothing by mouth) status is essential before surgery for a patient with Hirschsprung disease to prevent aspiration. Administering antibiotics, ensuring bowel rest, and performing regular enemas are not the priority interventions before surgery for this condition. Administering antibiotics may be necessary in the postoperative period to prevent infection, ensuring bowel rest can be beneficial but is not the priority, and performing regular enemas is not typically recommended before surgery for Hirschsprung disease.

3. What should be included in the teaching plan for parents of an infant diagnosed with phenylketonuria (PKU)?

• A. Mental retardation occurs if PKU is untreated.
• B. Testing for PKU is done immediately after birth.
• C. Treatment for PKU includes lifelong dietary management.
• D. PKU is transmitted as an autosomal recessive trait.

Correct answer: A

Rationale: The correct answer is A: 'Mental retardation occurs if PKU is untreated.' Phenylketonuria (PKU) is a metabolic disorder that results in the inability to metabolize phenylalanine properly. Without proper dietary management, high levels of phenylalanine can lead to severe mental retardation and other neurological problems. Therefore, educating parents about the importance of early and consistent treatment to prevent mental retardation is crucial. Choice B is incorrect because testing for PKU is typically done shortly after birth, not immediately. Choice C is incorrect because treatment for PKU primarily involves strict dietary management to control phenylalanine intake, not lifelong medications. Choice D is incorrect because PKU is inherited in an autosomal recessive pattern, not as an autosomal dominant gene.

4. 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.

5. 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.
