1. Which medication is typically used for long-term control of asthma?

• A. Albuterol
• B. Theophylline
• C. Ipratropium
• D. Prednisone

Correct answer: B

Rationale: The correct answer is B, Theophylline. Theophylline is commonly used for long-term control of asthma by relaxing the muscles around the airways to keep them open, making breathing easier. Albuterol (choice A) is a short-acting bronchodilator for quick relief of asthma symptoms, not for long-term control. Ipratropium (choice C) is another short-acting bronchodilator that helps open the airways but is not typically used for long-term control. Prednisone (choice D) is a corticosteroid usually used for short periods to control asthma exacerbations or flare-ups, not as a long-term control medication.

2. Gram for gram, which class of nutrient provides the most energy?

• A. fats
• B. alcohols
• C. proteins
• D. carbohydrates

Correct answer: A

Rationale: The correct answer is fats. Fats provide 9 kilocalories per gram, which is more energy-dense compared to proteins and carbohydrates. While proteins and carbohydrates provide 4 kilocalories per gram, fats provide more than twice the energy, making them the most energy-providing nutrient. Alcohols are not considered essential nutrients and do not provide energy for the body, unlike fats, proteins, and carbohydrates. Therefore, fats are the correct answer for the most energy-providing nutrient.

3. What is the primary intervention for a child experiencing a tonic-clonic seizure?

• A. Administer intravenous fluids
• B. Place the child in a prone position
• C. Protect the child from injury
• D. Perform mouth-to-mouth resuscitation

Correct answer: C

Rationale: The primary intervention for a child experiencing a tonic-clonic seizure is to protect them from injury. Placing the child in a prone position can be dangerous as it may lead to further harm due to the risk of aspiration or airway obstruction. Administering intravenous fluids is not recommended during a seizure. Performing mouth-to-mouth resuscitation is also not indicated as the child will resume breathing spontaneously after the seizure stops. Ensuring the child's safety and preventing injury by removing harmful objects and cushioning their head is essential until the seizure subsides.

4. Which lab result should be abnormal in a child with hemophilia?

• A. Prothrombin time
• B. Bleeding time
• C. Platelet count
• D. Partial thromboplastin time

Correct answer: D

Rationale: In a child with hemophilia, the lab result that should be abnormal is the partial thromboplastin time (PTT). Hemophilia is a disorder that affects the clotting factors in the intrinsic pathway of coagulation, leading to a prolonged PTT. Prothrombin time (Choice A) assesses the extrinsic pathway and should be normal in hemophilia. Bleeding time (Choice B) evaluates platelet function, which is typically normal in hemophilia. Platelet count (Choice C) measures the number of platelets and is not directly affected by hemophilia.

5. What is the study of how a person's genes interact with nutrients?

• A. genetic counseling
• B. nutritional genomics
• C. genetic metabolomics
• D. nutritional genetics

Correct answer: B

Rationale: Nutritional genomics, the correct answer, specifically focuses on how a person's genes interact with nutrients, affecting health and disease. Genetic counseling (choice A) refers to the process of helping people understand and adapt to the medical, psychological, and familial implications of genetic contributions to disease. Genetic metabolomics (choice C) combines genetic and metabolomic data to study metabolic pathways. Nutritional genetics (choice D) generally refers to the broader field of genetics as it relates to nutrition, while nutritional genomics, the most precise term, delves into the specific gene-nutrient interactions.
