1. 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.

2. How does a double-blind experiment work?

• A. Both subject groups take turns receiving each treatment.
• B. Neither subjects nor researchers know which subjects are in the control or experimental group.
• C. Neither group of subjects knows whether they are in the control or experimental group, but the researchers do not know.
• D. Both subject groups know whether they are in the control or experimental group, but the researchers do not know.

Correct answer: B

Rationale: The correct answer is B. In a double-blind experiment, neither the subjects nor the researchers know which subjects are in the control or experimental group. This helps to eliminate bias and ensure that the results are more objective. Choice A is incorrect as in a double-blind experiment, subjects do not take turns receiving each treatment; it is about masking the treatment allocation. Choice C is incorrect because it implies that the researchers are aware of the group allocation, which goes against the principle of blinding in a double-blind study. Choice D is incorrect as both subject groups should not know whether they are in the control or experimental group to maintain the blindness of the study.

3. In what units are energy measurements expressed by most scientists and nutritionists outside the United States?

• A. newtons
• B. liters
• C. kilojoules
• D. kilocalories

Correct answer: C

Rationale: Kilojoules are the standard units of energy used by most scientists and nutritionists worldwide. Newtons are units of force, liters are units of volume, and kilocalories are more commonly used in the United States but not as widely adopted internationally for energy measurements. Therefore, the correct answer is 'kilojoules.'

4. What is a common early sign of RSV (respiratory syncytial virus) in infants?

• A. High fever
• B. Nasal congestion
• C. Rash
• D. Jaundice

Correct answer: B

Rationale: Nasal congestion is a common early sign of RSV in infants, often accompanied by cough and wheezing. High fever, rash, and jaundice are not typically associated with RSV. While RSV can lead to fever, it is usually not one of the earliest signs. Rash and jaundice are unrelated to RSV symptoms.

5. What intervention is recommended for a child with severe dehydration?

• A. Oral rehydration therapy
• B. Intravenous fluid replacement
• C. High-protein diet
• D. Increased physical activity

Correct answer: B

Rationale: Intravenous fluid replacement is the recommended intervention for a child with severe dehydration because it allows for rapid restoration of fluid and electrolyte balance. In severe cases, oral rehydration therapy (Choice A) may not be tolerated due to the child's condition. A high-protein diet (Choice C) is not the primary intervention and does not address the immediate fluid and electrolyte imbalance. Increased physical activity (Choice D) is contraindicated in severe dehydration as it can exacerbate fluid loss, making intravenous fluid replacement the most suitable choice for prompt correction of the severe dehydration.
