1. What does a positive correlation between two variables indicate?

• A. One variable causes the other.
• B. Both variables move in the same direction.
• C. Both variables move in opposite directions.
• D. There is no relationship between the variables.

Correct answer: B

Rationale: A positive correlation between two variables indicates that they move in the same direction. This means that as one variable increases (or decreases), the other variable also increases (or decreases). Choice A is incorrect because correlation does not imply causation; it only shows a relationship between variables. Choice C is incorrect as it describes a negative correlation where variables move in opposite directions. Choice D is incorrect as a positive correlation implies a relationship between the variables.

2. 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.

3. An essential nutrient is one that ___

• A. must be made in large quantities by the body
• B. can only be synthesized by the body
• C. cannot be made in sufficient quantities by the body
• D. is used to synthesize other compounds in the body

Correct answer: C

Rationale: An essential nutrient is a substance that cannot be made in sufficient quantities by the body itself, so it must be obtained from the diet. Choice A is incorrect because essential nutrients are required in specific amounts, not necessarily large quantities. Choice B is incorrect as essential nutrients cannot be synthesized by the body at all. Choice D is incorrect because although essential nutrients may be used in the synthesis of other compounds, that is not the defining characteristic of an essential nutrient.

4. Before publication in a reputable journal, the findings of a research study must undergo scrutiny by experts in the field in a process known as what?

• A. peer review
• B. cohort review
• C. research intervention
• D. double-blind examination

Correct answer: A

Rationale: The correct answer is A: peer review. Before publication, research findings must undergo peer review, where experts in the field evaluate the validity and significance of the study. Choice B, cohort review, is incorrect as it does not involve the same level of evaluation by experts. Choice C, research intervention, is not a term used to describe the evaluation process before publication. Choice D, double-blind examination, refers to a study design where neither the participants nor the researchers know who is receiving a particular treatment, which is not the same as the peer review process.

5. How should a healthcare professional approach the care of a child with a newly diagnosed type 1 diabetes?

• A. Emphasize the importance of blood glucose monitoring
• B. Avoid insulin therapy
• C. Encourage a high-carbohydrate diet
• D. Recommend alternative therapies only

Correct answer: A

Rationale: Corrected Rationale: Emphasizing the importance of blood glucose monitoring is crucial for managing type 1 diabetes effectively. Monitoring blood glucose levels helps in maintaining optimal control of the condition, adjusting treatment plans as necessary, and preventing complications. Choice B is incorrect because insulin therapy is the mainstay treatment for type 1 diabetes to regulate blood sugar levels. Choice C is incorrect because while diet is important, encouraging a high-carbohydrate diet can lead to fluctuations in blood sugar levels. Choice D is incorrect because alternative therapies should not replace standard medical treatment like insulin therapy in type 1 diabetes management.
