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. 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. Which characteristic is most typical of a chronic disease?

• A. It has a rapid onset.
• B. It rarely has noticeable symptoms.
• C. It produces sharp pains.
• D. It progresses gradually.

Correct answer: D

Rationale: The correct answer is D. Chronic diseases are characterized by a gradual progression over time, affecting individuals for an extended period. Option A is incorrect as chronic diseases do not have a rapid onset like acute conditions. Option B is incorrect as chronic diseases often manifest noticeable symptoms. Option C is incorrect as sharp pains are not a defining characteristic of chronic diseases. Chronic diseases can present a variety of symptoms depending on the specific condition, but gradual progression is a common feature distinguishing them from acute illnesses.

4. What should be a priority for a 4-year-old child with nephrosis?

• A. Impaired body image
• B. Skin impairment
• C. Nutritional deficit
• D. Injury

Correct answer: B

Rationale: The correct answer is B: Skin impairment. Skin care is a priority in nephrosis due to edema and increased risk of skin breakdown, requiring careful monitoring and management. While impaired body image (Choice A) can be a concern, it is not typically a priority in a 4-year-old with nephrosis. Nutritional deficit (Choice C) is important but addressing skin impairment takes precedence due to the immediate risk of complications related to skin breakdown. Injury (Choice D) is a general concern for children but is not the priority in a child with nephrosis.

5. The parents of a child with sickle cell anemia ask why their child experiences pain. What is the most likely cause?

• A. Inflammation of the vessels
• B. Obstructed blood flow
• C. Overhydration
• D. Stress-related headaches

Correct answer: B

Rationale: In sickle cell anemia, pain is primarily caused by the obstruction of blood flow by sickle-shaped cells. This obstruction leads to inadequate oxygen supply to tissues, resulting in tissue damage and pain. Choice A, inflammation of the vessels, is incorrect as it is not the primary cause of pain in sickle cell anemia. Choice C, overhydration, is unrelated to the pathophysiology of sickle cell anemia and would not lead to the characteristic pain experienced. Choice D, stress-related headaches, is also unrelated to the underlying mechanisms of pain in sickle cell anemia.
