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 nurse is assessing a 2-year-old child with suspected Down syndrome. What characteristic physical feature is the nurse likely to observe?

• A. Epicanthal folds
• B. Webbed neck
• C. Enlarged head
• D. Polydactyly

Correct answer: A

Rationale: Epicanthal folds are a distinctive physical feature commonly observed in individuals with Down syndrome. These are horizontal skin folds that cover the inner corners of the eyes. Webbed neck (choice B) is not typically associated with Down syndrome but can be seen in conditions like Turner syndrome. Enlarged head (choice C) is not a characteristic feature of Down syndrome; however, individuals with hydrocephalus may present with this finding. Polydactyly (choice D) is the presence of extra fingers or toes, which is not a typical feature of Down syndrome.

3. Congenital heart defects have traditionally been divided into acyanotic or cyanotic defects. Based on the nurse’s knowledge of congenital heart defects, this system in clinical practice is

• A. helpful because it explains the hemodynamics involved
• B. helpful because children with cyanotic defects are easily identified
• C. problematic because cyanosis is rarely present in children
• D. problematic because children with acyanotic heart defects may develop cyanosis

Correct answer: D

Rationale: The classification is problematic because children with acyanotic heart defects may develop cyanosis, complicating the differentiation between acyanotic and cyanotic defects. Choice A is incorrect because the system is not solely based on explaining hemodynamics. Choice B is incorrect because the classification is not based on the ease of identifying children with cyanotic defects. Choice C is incorrect because cyanosis can indeed be present in children with congenital heart defects, especially acyanotic defects that may lead to cyanosis under certain circumstances.

4. 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.

5. What is the most important intervention for a nurse to implement for a child with sickle cell anemia admitted to the hospital during a vaso-occlusive crisis?

• A. Administering oxygen
• B. Ensuring adequate hydration
• C. Monitoring vital signs
• D. Administering pain medication

Correct answer: B

Rationale: Ensuring adequate hydration is crucial during a vaso-occlusive crisis in sickle cell anemia as it helps to reduce the viscosity of the blood and prevent further sickling of the cells. While administering oxygen may be necessary in some cases, ensuring hydration takes precedence as it directly impacts the underlying pathophysiology of the crisis. Monitoring vital signs is important for ongoing assessment but does not directly address the crisis as hydration does. Administering pain medication is important for pain relief but does not address the primary issue of vaso-occlusion and is not the most crucial intervention in this scenario.
