1. 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.

2. What is a common symptom of an upper respiratory infection in children?

A. Constipation
B. Excessive vomiting
C. Nasal congestion
D. Abdominal pain

Correct answer: C

Rationale: Nasal congestion is a common symptom of an upper respiratory infection in children. It is typically accompanied by cough and sore throat. Constipation (choice A) and excessive vomiting (choice B) are not typical symptoms of upper respiratory infections. Abdominal pain (choice D) is more commonly associated with gastrointestinal issues rather than upper respiratory infections.

3. Which nutrient is an example of a macronutrient?

A. proteins
B. minerals
C. water-soluble vitamins
D. fat-soluble vitamins

Correct answer: A

Rationale: Proteins are indeed macronutrients as they are required by the body in larger quantities for various functions such as growth, repair, and energy production. Choice B, minerals, are micronutrients needed in smaller amounts for various physiological processes. Choices C and D, water-soluble vitamins and fat-soluble vitamins, respectively, are also micronutrients that play essential roles in the body but are not classified as macronutrients.

4. What is one benefit of using controls in an experiment?

A. The size of the groups does not matter.
B. The subjects are unaware of the experiment's details.
C. The subjects who are treated are balanced against the placebos.
D. The subjects are similar in all respects except for the treatment being tested.

Correct answer: D

Rationale: The correct answer is D. Controls in an experiment ensure that the subjects are similar in all respects except for the treatment being tested. This allows for a fair comparison between the treatment group and the control group. Choice A is incorrect because the size of the groups is not the primary benefit of using controls. Choice B is incorrect as blinding, not controls, refers to subjects not knowing about the experiment. Choice C is incorrect as it pertains more to randomization than the use of controls.

5. Following diarrhea, which foods should be offered to the school-age child?

A. Apricots and peaches
B. Chocolate milk
C. Applesauce and milk
D. Bananas and rice

Correct answer: D

Rationale: After a bout of diarrhea, it is important to offer foods that are gentle on the stomach and help in recovery. Bananas and rice are commonly recommended as they are easily digestible and can help firm up stools. Apricots, peaches, and applesauce may be too acidic and fibrous, potentially aggravating the stomach. Chocolate milk is high in sugar and can worsen diarrhea due to its lactose content.
