1. A major reason for the development of respiratory distress syndrome in the preterm infant is:

• A. Excessive surfactant
• B. Lack of surfactant
• C. Immature immune system
• D. Lack of body fat

Correct answer: B

Rationale: The correct answer is B: Lack of surfactant. Respiratory distress syndrome (RDS) in preterm infants is primarily due to a lack of surfactant, which is crucial for keeping the lungs inflated. Without adequate surfactant, the alveoli collapse, leading to breathing difficulties. Choice A, Excessive surfactant, is incorrect as RDS is caused by an insufficient amount of surfactant. Choice C, Immature immune system, and Choice D, Lack of body fat, are not directly related to the development of respiratory distress syndrome in preterm infants.

2. Which laboratory test would be most important for the nurse to assess when caring for a toddler suspected of having cystic fibrosis?

• A. Liver enzymes
• B. Serum calcium
• C. Sweat chloride test
• D. Urine creatinine

Correct answer: C

Rationale: The sweat chloride test is the primary diagnostic test for cystic fibrosis. Cystic fibrosis is characterized by abnormal transport of chloride and sodium across epithelial cell membranes, leading to increased chloride in sweat. This test is crucial for diagnosing cystic fibrosis in suspected cases. Liver enzymes (Choice A), serum calcium (Choice B), and urine creatinine (Choice D) are not specific tests for cystic fibrosis and would not provide the necessary information for diagnosis in this case.

3. What is the most appropriate action for a healthcare provider if a child presents with suspected meningitis?

• A. Administer antibiotics immediately
• B. Perform a lumbar puncture
• C. Isolate the child
• D. Obtain a complete blood count

Correct answer: C

Rationale: Isolating the child is a priority to prevent the spread of infection until meningitis is confirmed or ruled out. Meningitis, particularly bacterial, is highly contagious and can lead to outbreaks if not properly managed. Isolation and prompt treatment are critical in preventing serious complications. Administering antibiotics immediately without confirmation of the diagnosis can be harmful if the cause is viral or non-infectious. Performing a lumbar puncture is a diagnostic procedure that should be done by a healthcare provider but is not the initial action when suspecting meningitis. Obtaining a complete blood count may be part of the diagnostic workup but is not the most appropriate initial action in suspected meningitis.

4. One of the major differences in clinical presentation between Crohn disease (CD) and ulcerative colitis (UC) is that UC is more likely to cause which clinical manifestation?

• A. Pain
• B. Rectal bleeding
• C. Perianal lesions
• D. Growth retardation

Correct answer: B

Rationale: Rectal bleeding is more commonly associated with ulcerative colitis (UC) than with Crohn disease (CD). While both conditions can cause abdominal pain and growth issues, bleeding is a hallmark of UC due to its superficial mucosal inflammation. Perianal lesions are more characteristic of CD, and growth retardation is typically not a direct clinical manifestation of either CD or UC.

5. The nurse is caring for a child who had a tonsillectomy. Which clinical manifestation should the nurse observe the child for in the postoperative period?

• A. Arrhythmias
• B. Increased swallowing
• C. Increased blood sugar
• D. Increased urinary output

Correct answer: B

Rationale: Correct Answer: B. Increased swallowing can indicate bleeding at the surgical site, which is a potential complication after tonsillectomy. Choice A, Arrhythmias, are not typically associated with tonsillectomy. Choice C, Increased blood sugar, is not a common clinical manifestation after a tonsillectomy. Choice D, Increased urinary output, is not a typical clinical manifestation to observe for in the postoperative period after a tonsillectomy.
