1. Which lab result should be abnormal in a child with hemophilia?

• A. Prothrombin time
• B. Bleeding time
• C. Platelet count
• D. Partial thromboplastin time

Correct answer: D

Rationale: In a child with hemophilia, the lab result that should be abnormal is the partial thromboplastin time (PTT). Hemophilia is a disorder that affects the clotting factors in the intrinsic pathway of coagulation, leading to a prolonged PTT. Prothrombin time (Choice A) assesses the extrinsic pathway and should be normal in hemophilia. Bleeding time (Choice B) evaluates platelet function, which is typically normal in hemophilia. Platelet count (Choice C) measures the number of platelets and is not directly affected by hemophilia.

2. You have been asked to help a top nutrition researcher conduct human experiments on vitamin C. As the subjects walk into the laboratory, you distribute all the vitamin C pill bottles to the girls and all the placebo pill bottles to the boys. What should you have done?

• A. Giving all the boys the vitamin C and the girls the placebo, and telling them what they were getting.
• B. Distributing the bottles randomly, randomizing the subjects, and telling them what they were getting.
• C. Telling the subjects which group they were in, but preventing yourself from knowing the contents of the pill bottles.
• D. Preventing yourself from knowing what is in the pill bottles, and distributing the bottles randomly to the subjects.

Correct answer: D

Rationale: The correct approach in a scientific experiment is to prevent yourself from knowing the contents of the pill bottles and distribute them randomly to the subjects. This randomization helps to avoid bias and ensures that the results are not influenced by preconceived notions. Option A is incorrect because it introduces gender bias by assigning pills based on gender. Option B is incorrect as it mentions telling the subjects what they are getting, which could lead to placebo effects. Option C is incorrect as it suggests disclosing group information to the subjects, which can also introduce bias.

3. What is a key preventive measure for avoiding urinary tract infections (UTIs) in children?

• A. Restrict fluid intake
• B. Encourage frequent urination
• C. Use topical antibiotics
• D. Increase dietary calcium

Correct answer: B

Rationale: Encouraging frequent urination is a key preventive measure for avoiding urinary tract infections (UTIs) in children. It helps flush bacteria from the urinary tract, reducing the risk of UTIs. Restricting fluid intake (Choice A) is not recommended as it may lead to concentrated urine and increase the risk of UTIs. Using topical antibiotics (Choice C) is not a preventive measure for UTIs and should only be used under medical guidance. Increasing dietary calcium (Choice D) is not directly linked to preventing UTIs in children.

4. How should a healthcare provider approach the care of a child with a suspected fracture?

• A. Immobilize the affected limb and seek medical evaluation
• B. Apply heat to the injury
• C. Allow the child to continue normal activity
• D. Administer over-the-counter pain relief only

Correct answer: A

Rationale: When a child is suspected to have a fracture, it is essential to immobilize the affected limb to prevent further injury. Seeking immediate medical evaluation is crucial for an accurate diagnosis and appropriate treatment. Applying heat to a suspected fracture can worsen the condition by increasing swelling and pain. Allowing the child to continue normal activity can lead to further damage. Administering only over-the-counter pain relief is insufficient and does not address the need for immobilization and professional evaluation.

5. How should a caregiver manage a child with a new diagnosis of sickle cell anemia?

• A. Ensure the child receives frequent blood transfusions
• B. Promote adequate hydration and pain management
• C. Restrict physical activity
• D. Administer high doses of vitamin C

Correct answer: B

Rationale: Promoting adequate hydration and pain management is crucial for managing sickle cell anemia to prevent crises and complications. Adequate hydration helps prevent sickling of red blood cells, while effective pain management is essential for addressing the frequent pain episodes associated with the condition. Ensuring the child receives frequent blood transfusions is not the initial management for sickle cell anemia; transfusions are usually reserved for specific complications. Restricting physical activity should be individualized based on the child's condition; some physical activity is beneficial for overall health. Administering high doses of vitamin C is not a standard treatment for sickle cell anemia and does not address the underlying pathology of the disease.
