1. What is a common side effect of the antibiotic tetracycline in children?

• A. Discoloration of teeth
• B. Increased appetite
• C. Elevated blood glucose levels
• D. Decreased bone density

Correct answer: A

Rationale: Discoloration of teeth is a well-known side effect of tetracycline, especially when administered to children below 8 years of age. Tetracycline can bind to calcium ions in developing teeth, causing them to become discolored and appear yellow or brown. Increased appetite, elevated blood glucose levels, and decreased bone density are not commonly associated with the use of tetracycline in children, making them incorrect choices.

2. What is a common early sign of type 1 diabetes in children?

• A. Excessive thirst and frequent urination
• B. Severe abdominal pain
• C. Frequent headaches
• D. Sudden weight gain

Correct answer: A

Rationale: Excessive thirst and frequent urination are common early signs of type 1 diabetes in children. These symptoms occur due to high blood glucose levels, leading to increased thirst and urination. Severe abdominal pain (choice B) is not typically associated with type 1 diabetes. Although frequent headaches (choice C) can occur in some cases, they are not as specific to type 1 diabetes as excessive thirst and frequent urination. Sudden weight gain (choice D) is not a common early sign of type 1 diabetes; in fact, unexplained weight loss is more characteristic of the condition.

3. 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.

4. How does a double-blind experiment work?

• A. Both subject groups take turns receiving each treatment.
• B. Neither subjects nor researchers know which subjects are in the control or experimental group.
• C. Neither group of subjects knows whether they are in the control or experimental group, but the researchers do not know.
• D. Both subject groups know whether they are in the control or experimental group, but the researchers do not know.

Correct answer: B

Rationale: The correct answer is B. In a double-blind experiment, neither the subjects nor the researchers know which subjects are in the control or experimental group. This helps to eliminate bias and ensure that the results are more objective. Choice A is incorrect as in a double-blind experiment, subjects do not take turns receiving each treatment; it is about masking the treatment allocation. Choice C is incorrect because it implies that the researchers are aware of the group allocation, which goes against the principle of blinding in a double-blind study. Choice D is incorrect as both subject groups should not know whether they are in the control or experimental group to maintain the blindness of the study.

5. Which statement best describes the composition of most foods?

• A. Most foods contain a mixture of the three energy nutrients, with one or two predominating.
• B. Foods do not typically contain equal amounts of the three energy nutrients.
• C. Most foods contain mixtures of the three energy nutrients, although only one or two may predominate.
• D. Most foods contain all three energy nutrients in varying amounts.

Correct answer: C

Rationale: The correct answer is C. Most foods contain a mixture of the three energy nutrients (carbohydrates, proteins, fats), with one or two predominating. Choice A is correct because most foods do contain a combination of energy nutrients, with one or two types usually being predominant. Choice B is incorrect as foods typically do not contain equal amounts of carbohydrates, proteins, and fats. Choice D is incorrect because most foods contain all three energy nutrients, not just one or two types.
