Which of the following is a poor food source of iron?
- A. Dried fruits
- B. Cheese
- C. Clams
- D. Legumes
Correct Answer: B
Rationale: Iron is an essential nutrient for the body, and while it can be found in many different types of foods, the amounts can vary significantly. Cheese, while a good source of other nutrients like calcium and protein, is not a particularly rich source of iron. On the other hand, clams, legumes, and dried fruits are known to contain higher levels of iron. Therefore, among the provided choices, cheese is considered a poor source of iron. It's important to note that a balanced diet should include a variety of foods to ensure the intake of all necessary nutrients.

For a patient with celiac disease, which dietary modification is necessary?
- A. Increase protein intake
- B. Avoid gluten
- C. Increase dairy intake
- D. Avoid lactose
Correct Answer: B
Rationale: The correct answer is B: Avoid gluten. Patients with celiac disease have an immune reaction to gluten, a protein found in wheat, barley, and rye. Therefore, it is crucial for individuals with celiac disease to avoid gluten-containing products. Increasing protein intake (Choice A) is not specifically necessary for celiac disease management. Increasing dairy intake (Choice C) is unrelated to the dietary requirements of individuals with celiac disease. Avoiding lactose (Choice D) is relevant for individuals with lactose intolerance, not celiac disease. Therefore, the only necessary modification for a patient with celiac disease is to avoid gluten.
What should be recommended to help prevent early childhood caries (ECC) in infants?
- A. Avoid giving the infant nighttime bottles
- B. Have the infant drink pasteurized skim milk
- C. Feed the infant iron-rich foods
- D. Give the infant fruit juice to drink
Correct Answer: A
Rationale: The correct answer is 'A: Avoid giving the infant nighttime bottles' because prolonged exposure to sugars in milk during the night can lead to caries. Options 'B: Have the infant drink pasteurized skim milk' and 'D: Give the infant fruit juice to drink' are not recommended as they contain sugars that can cause cavities, especially in infants. Option 'C: Feed the infant iron-rich foods' is incorrect because while a balanced diet is important, iron-rich foods do not directly prevent caries development.
What is the term for a barrier that prevents the normal emptying of stomach contents into the duodenum?
- A. Dumping syndrome
- B. Gastritis
- C. Gastric outlet obstruction
- D. Hypochlorhydria
Correct Answer: C
Rationale: Gastric outlet obstruction refers to a condition where the opening between the stomach and the duodenum is blocked, preventing the normal passage of food. This is why choice 'C' is correct. 'A: Dumping syndrome' is incorrect because it is a condition where stomach contents move too quickly through the small intestine, not a barrier preventing emptying. 'B: Gastritis' is inflammation of the stomach lining, not a blockage of the outlet. 'D: Hypochlorhydria' refers to low stomach acid, which may affect digestion but does not create a physical barrier blocking the outlet of the stomach.
What type of drug therapy is typically administered immediately after a heart attack?
- A. Antilipemic drugs
- B. Corticosteroids
- C. Diuretics
- D. Thrombolytic drugs
Correct Answer: D
Rationale: Thrombolytic drugs are typically administered immediately after a heart attack to dissolve the clot blocking the coronary artery and restore blood flow to the heart muscle. Antilipemic drugs are used to lower lipid levels and prevent atherosclerosis, but they are not typically administered immediately after a heart attack. Corticosteroids are used to reduce inflammation and suppress the immune response, which are not immediate concerns after a heart attack. Diuretics are used to reduce fluid build-up and lower blood pressure, but these are not the primary concerns immediately following a heart attack.
When is Prevident indicated?
- A. High caries risk
- B. Crown and bridge work
- C. Orthodontic decalcification
- D. All of the above
Correct Answer: D
Rationale: Prevident is indicated for all the situations listed in the choices. It is recommended for patients with a high risk of caries to reduce the risk of tooth decay. It is also used in dental procedures like crown and bridge work to strengthen enamel and prevent cavities. Furthermore, it is utilized for orthodontic decalcification to aid in remineralizing the tooth structure and prevent further damage. Therefore, the correct answer is 'All of the above.' While choices A, B, and C are individually correct, selecting 'All of the above' is the most appropriate as it encompasses all the possible indications for Prevident.
