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.

Which of the following is a function of carbohydrates in the body?
- A. They provide insulation and support for organs.
- B. They help regulate body temperature.
- C. They serve as the body's main structural components.
- D. They are the body's primary source of energy.
Correct Answer: D
Rationale: The correct answer is D. Carbohydrates are the body's primary source of energy, fueling daily activities and bodily functions. Choice A is incorrect because insulation and organ support are primarily provided by adipose tissue and structural proteins, not carbohydrates. Choice B is incorrect because the regulation of body temperature is mainly controlled by processes like sweating and shivering, not carbohydrates. Choice C is incorrect because structural components like proteins are responsible for building tissues and organs, not carbohydrates.
What is a key dietary consideration for a child with phenylketonuria (PKU)?
- A. High-fiber diet
- B. Low-phenylalanine diet
- C. Increased dairy intake
- D. High-sodium diet
Correct Answer: B
Rationale: A low-phenylalanine diet is crucial for managing PKU to prevent neurological damage and maintain normal development. Phenylalanine is an amino acid found in protein-containing foods, and individuals with PKU have difficulty metabolizing it. Consuming foods low in phenylalanine helps prevent the buildup of toxic byproducts in the body. Choices A, C, and D are incorrect. A high-fiber diet, increased dairy intake, and high-sodium diet are not specific dietary considerations for PKU management. In fact, dairy products are a source of protein and phenylalanine, which should be limited in PKU.
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.
How should a healthcare provider respond to a parent concerned about their child's frequent ear infections?
- A. Recommend over-the-counter ear drops
- B. Suggest an ENT specialist evaluation
- C. Advise on increasing fluid intake
- D. Encourage more physical exercise
Correct Answer: B
Rationale: When a parent expresses concerns about their child's frequent ear infections, suggesting an ENT specialist evaluation is the most appropriate response. This specialist can conduct a thorough examination to identify the underlying cause of the recurrent infections and recommend the most suitable treatment. Recommending over-the-counter ear drops (Choice A) may not address the root cause of the issue and could potentially lead to inappropriate treatment. Advising on increasing fluid intake (Choice C) and encouraging more physical exercise (Choice D) are unrelated to addressing the specific concern of frequent ear infections.
What is a common symptom of a respiratory infection in infants?
- A. Wheezing
- B. High appetite
- C. Increased thirst
- D. Lethargy
Correct Answer: A
Rationale: Wheezing is a common symptom of respiratory infections in infants, often associated with coughing and difficulty breathing. It occurs due to the narrowing of the airways. Choice B, 'High appetite,' is incorrect as respiratory infections usually lead to a decrease in appetite rather than an increase. Choice C, 'Increased thirst,' is incorrect as it is not a typical symptom of a respiratory infection in infants. Choice D, 'Lethargy,' can be a symptom of respiratory infections but is not as specific and common as wheezing.
