1. What is the primary purpose of a placebo in an experiment?

• A. To reduce the cost of the experiment.
• B. To make the experiment double-blind.
• C. To increase the number of participants.
• D. To serve as a control for comparison with the treatment group.

Correct answer: D

Rationale: The correct answer is D. A placebo serves as a control for comparison with the treatment group, helping to eliminate bias and ensure the results are due to the treatment itself. Placebos are crucial in research to distinguish the actual effect of the treatment from psychological or subjective factors. Choice A is incorrect because the purpose of a placebo is not related to reducing the cost of the experiment. Choice B is incorrect because while placebos are used in double-blind studies, their primary purpose is not to make the experiment double-blind. Choice C is incorrect because the purpose of a placebo is not to increase the number of participants but rather to serve as a comparison group for the treatment being tested.

2. What is an important nursing intervention for a child with a newly inserted central venous catheter?

• A. Regularly monitor for signs of infection
• B. Administer intravenous fluids only as ordered
• C. Restrict the child's movement
• D. Perform daily dressing changes only

Correct answer: A

Rationale: Regularly monitoring for signs of infection is a critical nursing intervention for a child with a newly inserted central venous catheter. This intervention is essential to detect any early signs of infection, such as redness, swelling, or drainage at the catheter site, which can lead to serious complications like sepsis. Administering intravenous fluids as ordered is important but not the most crucial intervention for a newly inserted central venous catheter. Restricting the child's movement is unnecessary unless specified by the healthcare provider. Performing daily dressing changes alone is not sufficient to ensure the catheter's integrity and the child's safety; monitoring for signs of infection is key.

3. What should be monitored in a child receiving chemotherapy?

• A. Blood glucose levels
• B. Blood cell counts
• C. Weight gain
• D. Skin elasticity

Correct answer: B

Rationale: The correct answer is monitoring blood cell counts. During chemotherapy, it is crucial to monitor blood cell counts to detect potential side effects such as neutropenia (low white blood cell count) and anemia (low red blood cell count). These conditions can increase the risk of infections and fatigue. Monitoring blood glucose levels (Choice A) is not typically a primary concern in children receiving chemotherapy unless they have pre-existing conditions like diabetes. Weight gain (Choice C) and skin elasticity (Choice D) are not directly related to monitoring the effects of chemotherapy in children. Therefore, the most important parameter to monitor in a child receiving chemotherapy is blood cell counts.

4. What is an essential aspect of managing a child with juvenile idiopathic arthritis (JIA)?

• A. Encouraging joint mobility and physical therapy
• B. Restricting all forms of exercise
• C. Increasing sugar intake
• D. Using only oral medications

Correct answer: A

Rationale: Encouraging joint mobility and physical therapy is crucial in managing juvenile idiopathic arthritis (JIA). This approach helps maintain joint function, reduce stiffness, and improve the overall quality of life for children with JIA. Restricting all forms of exercise (Choice B) is not recommended, as appropriate physical activity is beneficial for joint health and overall well-being. Increasing sugar intake (Choice C) is not a recommended practice for managing JIA, as a healthy diet is important for overall well-being and can help reduce inflammation. Using only oral medications (Choice D) may not be sufficient for managing JIA, as a comprehensive treatment plan often includes a combination of medications, physical therapy, and other interventions to effectively manage the condition.

5. What is a common early sign of RSV (respiratory syncytial virus) in infants?

• A. High fever
• B. Nasal congestion
• C. Rash
• D. Jaundice

Correct answer: B

Rationale: Nasal congestion is a common early sign of RSV in infants, often accompanied by cough and wheezing. High fever, rash, and jaundice are not typically associated with RSV. While RSV can lead to fever, it is usually not one of the earliest signs. Rash and jaundice are unrelated to RSV symptoms.
