1. 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.

2. Which statement best describes the relationship between diet and chronic diseases?

A. Diet has no impact on chronic diseases.
B. A poor diet can increase the risk of developing chronic diseases.
C. Diet is the sole cause of chronic diseases.
D. A balanced diet can help prevent or manage chronic diseases.

Correct answer: B

Rationale: Choice B is the correct answer. A poor diet can increase the risk of developing chronic diseases due to the lack of essential nutrients or the presence of harmful components like excessive sugar, salt, or saturated fats. While diet plays a significant role in the development of chronic diseases, it is not the sole cause (choice C). Choice A is incorrect because diet does indeed have a significant impact on chronic diseases. Choice D is not the best answer as it does not acknowledge the negative impact of a poor diet on chronic diseases.

3. By chemical analysis, what nutrient is present in the highest amounts in most foods?

A. fats
B. water
C. proteins
D. carbohydrates

Correct answer: B

Rationale: The correct answer is B. Water is the most abundant nutrient in many foods. Water content varies across different foods, but in general, it is present in the highest amounts. Fats (Choice A) are essential but are not found in higher amounts compared to water. Proteins (Choice C) and carbohydrates (Choice D) are also important nutrients, but they are typically found in lower quantities in most foods compared to water.

4. What should be included in the medical management of a sickle cell crisis?

A. Information for parents on home care
B. Adequate hydration and pain management
C. Pain management and iron supplements
D. Adequate oxygenation and factor VIII

Correct answer: B

Rationale: The correct answer is B: Adequate hydration and pain management. During a sickle cell crisis, it is essential to provide hydration to prevent vaso-occlusive events and manage pain effectively with analgesics. Adequate hydration helps maintain blood flow and prevent further sickling of red blood cells. Pain management is crucial to alleviate the severe pain associated with sickle cell crises. Options A, C, and D are incorrect. Providing information for parents on home care (Option A) may be important for ongoing management but is not specific to an acute crisis. Iron supplements (Option C) are not typically indicated during a sickle cell crisis. Adequate oxygenation and factor VIII (Option D) are not primary interventions for managing a sickle cell crisis; instead, oxygen therapy may be considered in severe cases, and factor VIII is not a standard treatment for sickle cell disease.

5. Which statement best describes the composition of most foods?

A. Most foods contain a mixture of the three energy nutrients, with one or two predominating.
B. Foods do not typically contain equal amounts of the three energy nutrients.
C. Most foods contain mixtures of the three energy nutrients, although only one or two may predominate.
D. Most foods contain all three energy nutrients in varying amounts.

Correct answer: C

Rationale: The correct answer is C. Most foods contain a mixture of the three energy nutrients (carbohydrates, proteins, fats), with one or two predominating. Choice A is correct because most foods do contain a combination of energy nutrients, with one or two types usually being predominant. Choice B is incorrect as foods typically do not contain equal amounts of carbohydrates, proteins, and fats. Choice D is incorrect because most foods contain all three energy nutrients, not just one or two types.
