What type of nutrient is needed by the body and must be supplied by foods?
- A. nutraceutical
- B. metabolic nutrient
- C. organic nutrient
- D. essential nutrient
Correct Answer: D
Rationale: The correct answer is D, essential nutrient. Essential nutrients are substances that the body needs for normal functioning but cannot produce in sufficient amounts, so they must be obtained through the diet. Nutraceuticals (choice A) are products derived from food sources that are purported to provide extra health benefits beyond basic nutrition. Metabolic nutrients (choice B) and organic nutrients (choice C) are not standard terms used to describe nutrients needed by the body. Therefore, choices A, B, and C are incorrect.

When an increase in exercise is accompanied by a decrease in body weight, it is an example of what?
- A. variable effect
- B. positive correlation
- C. negative correlation
- D. randomization effect
Correct Answer: C
Rationale: When an increase in exercise is accompanied by a decrease in body weight, it demonstrates a negative correlation. This means that as one variable (exercise) increases, the other variable (body weight) decreases. Choice A, 'variable effect,' is vague and does not accurately describe the relationship between exercise and body weight. Choice B, 'positive correlation,' is incorrect because in a positive correlation, both variables would increase or decrease together. Choice D, 'randomization effect,' is unrelated to the scenario described.
What is a common sign of a respiratory infection in infants?
- A. Increased appetite
- B. Rapid breathing
- C. Decreased urine output
- D. Lethargy
Correct Answer: B
Rationale: Rapid breathing is a common sign of a respiratory infection in infants. When infants have a respiratory infection, their breathing may become rapid as their body tries to get more oxygen. This symptom is often seen alongside cough and fever. Increased appetite (Choice A) is not typically associated with respiratory infections but can be seen in other conditions. Decreased urine output (Choice C) is more indicative of dehydration or kidney issues rather than a respiratory infection. Lethargy (Choice D) can be a symptom of various illnesses but is not as specific to respiratory infections as rapid breathing.
What is the primary treatment for a child with an anaphylactic reaction?
- A. Oral antihistamines
- B. Intravenous fluids
- C. Epinephrine injection
- D. Antipyretics
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.
What is a common sign of a urinary tract infection in older children?
- A. Frequent urination
- B. Increased appetite
- C. Elevated blood pressure
- D. Decreased energy levels
Correct Answer: A
Rationale: Frequent urination is a common sign of a urinary tract infection in older children. It is often accompanied by other symptoms such as pain or discomfort. Increased appetite (Choice B) is not typically associated with urinary tract infections. Elevated blood pressure (Choice C) is more commonly linked to conditions like hypertension, not urinary tract infections. Decreased energy levels (Choice D) can be a sign of various health issues but are not a typical symptom of a urinary tract infection.
How should a healthcare professional handle a child with a new diagnosis of type 2 diabetes?
- A. Focus on increasing physical activity and dietary management
- B. Initiate insulin therapy immediately
- C. Limit all carbohydrate intake
- D. Recommend frequent fasting
Correct Answer: A
Rationale: In managing type 2 diabetes in a child, focusing on increasing physical activity and dietary management is crucial, especially in the initial treatment phase. This approach helps improve insulin sensitivity and overall glycemic control. Initiating insulin therapy immediately is not the first-line treatment for type 2 diabetes in children. Limiting all carbohydrate intake is not advisable as carbohydrates are essential for providing energy and nutrients. Recommending frequent fasting can be harmful and is not a recommended strategy for managing type 2 diabetes in children.
