1. In the scientific method, a tentative solution to a problem is called a what?

Correct answer: C

Rationale: In the scientific method, a hypothesis is a tentative solution or educated guess that is tested through research. A theory (choice A) is a well-substantiated explanation based on evidence and extensive testing. A prediction (choice B) is a statement about what will happen in the future based on existing knowledge. Correlation (choice D) refers to a mutual relationship between two or more things, indicating how they may change together but not providing a solution to a problem.

2. What is a common symptom of congenital heart disease in infants?

Correct answer: B

Rationale: Difficulty breathing is a common symptom of congenital heart disease in infants. Infants with congenital heart disease may experience difficulty breathing due to impaired cardiac function, which affects the heart's ability to pump blood effectively. This symptom is often due to issues like heart failure or fluid accumulation in the lungs. Excessive weight gain (Choice A) is not typically associated with congenital heart disease in infants. High blood pressure (Choice C) is less common in infants with congenital heart disease compared to adults. Increased appetite (Choice D) is not a typical symptom of congenital heart disease in infants.

3. Which statement is true of minerals in their role as nutrients?

Correct answer: C

Rationale: The correct statement is that some minerals become dissolved in body fluids, making them available for absorption and utilization by the body. Minerals are not organic compounds, so choice A is incorrect. Choice B is incorrect because minerals do not provide energy like macronutrients such as carbohydrates and fats. Choice D is incorrect because minerals are elements and cannot be destroyed by cooking; however, their availability and absorption may be affected by cooking methods.

4. What is the primary treatment for a child with an anaphylactic reaction?

Correct answer: C

Rationale: The correct answer is C: Epinephrine injection. An epinephrine injection is the primary treatment for an anaphylactic reaction in children. Epinephrine acts quickly to reverse severe symptoms such as difficulty breathing, low blood pressure, and hives. Oral antihistamines, although useful for milder allergic reactions, are not sufficient to manage the potentially life-threatening symptoms of anaphylaxis. Intravenous fluids may be necessary to support blood pressure in a child with anaphylaxis but are not the primary treatment. Antipyretics, on the other hand, are medications used to reduce fever and are not indicated as the primary treatment for an anaphylactic reaction.

5. The motive for a person who alters their diet due to religious convictions is most likely related to their ___.

Correct answer: A

Rationale: The correct answer is A, 'values.' When individuals alter their diet due to religious convictions, it is primarily driven by their personal or cultural values associated with their faith. This choice reflects the strong influence that religious beliefs can have on dietary choices. Choice B, 'body image,' is incorrect because altering one's diet for religious reasons is more about spiritual beliefs than physical appearance. Choice C, 'ethnic heritage,' is incorrect as it pertains more to cultural background rather than religious convictions. Choice D, 'functional association,' is incorrect as it does not directly relate to the motivation behind altering one's diet for religious reasons.
