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. A newborn is diagnosed with metatarsus adductus. The parents ask the nurse how this occurred. Which response by the nurse would be most appropriate?

• A. This condition is due to a genetic defect in the bones.
• B. It's most likely from how the baby was positioned in utero.
• C. They really don't know what causes this condition.
• D. There is probably an underlying deformity of the baby's hip.

Correct answer: B

Rationale: Metatarsus adductus is a condition characterized by the inward turning of the front part of the foot. It is often caused by the baby's position in the womb, leading to the foot adopting this position. Choice A is incorrect because metatarsus adductus is primarily related to positioning in utero rather than a genetic defect. Choice C is incorrect as there is an understanding of the common cause of this condition. Choice D is incorrect because metatarsus adductus specifically refers to a foot deformity, not a hip deformity.

3. A 10-year-old girl is living with a foster family. Which intervention is the priority for the child in this family structure?

• A. Determining if the child is being bullied at school
• B. Dealing with mixed expectations of parents
• C. Establishing who is the child's actual caretaker
• D. Performing a comprehensive health assessment

Correct answer: D

Rationale: Performing a comprehensive health assessment is crucial for a child living with a foster family as they may have moved between different homes, leading to incomplete medical records. This assessment helps identify any existing health issues, ensure appropriate care, and address any unmet health needs. While addressing issues like bullying or parental expectations is important, the immediate priority should be ensuring the child's overall health and well-being. Establishing the actual caretaker is also important but may not be as urgent as addressing potential health concerns.

4. A nurse is caring for an infant with a tentative diagnosis of hypertrophic pyloric stenosis (HPS). What is most important for the nurse to assess?

• A. Quality of the cry
• B. Signs of dehydration
• C. Coughing up feedings
• D. Characteristics of the stool

Correct answer: B

Rationale: The correct answer is B: Signs of dehydration. Assessing for signs of dehydration is crucial in infants with hypertrophic pyloric stenosis (HPS) because they are at high risk due to frequent vomiting. Dehydration can lead to serious complications if not promptly addressed. Choices A, C, and D are not the priority assessments for HPS. While the quality of the cry can provide some information on the infant's distress level, dehydration assessment takes precedence. Coughing up feedings may not be specific to HPS, and characteristics of the stool, although important in general assessments, are not the priority in this situation.

5. An infant who has had diarrhea for 3 days is admitted in a lethargic state and is breathing rapidly. The parent states that the baby has been ingesting formula, although not as much as usual, and cannot understand the sudden change. What explanation should the nurse give the parent?

• A. Cellular metabolism is unstable in young children.
• B. The proportion of water in the body is less than in adults.
• C. Renal function is immature in children until they reach school age.
• D. The extracellular fluid requirement per unit of body weight is greater than in adults.

Correct answer: D

Rationale: The correct answer is D. Infants have a higher extracellular fluid requirement per unit of body weight, making them more susceptible to dehydration and electrolyte imbalances during illnesses such as diarrhea. Choice A is incorrect because cellular metabolism being unstable is not the primary explanation for the symptoms described. Choice B is incorrect as the proportion of water in the body alone does not fully explain the increased risk of dehydration in infants. Choice C is incorrect because while renal function is immature in children, it is not the most relevant factor in this scenario compared to the increased fluid requirements.
