1. Which nutrient is most important for the prevention of osteoporosis?

• A. Vitamin A
• B. Iron
• C. Calcium
• D. Protein

Correct answer: C

Rationale: Calcium is the most important nutrient for bone health and the prevention of osteoporosis. Calcium plays a crucial role in maintaining bone density and strength. Vitamin A is important for vision and immune function but is not directly related to bone health. Iron is essential for oxygen transport in the blood, while protein is important for muscle growth and repair. However, in the context of preventing osteoporosis, calcium is the key nutrient.

2. A nurse is caring for a client following a CVA and observes the client experiencing severe dysphagia. The nurse notifies the provider. Which of the following nutritional therapies will likely be prescribed?

• A. NPO until dysphagia subsides
• B. Supplements via nasogastric tube
• C. Initiation of total parenteral nutrition
• D. Soft residue diet

Correct answer: B

Rationale: In the scenario of severe dysphagia following a CVA, the client may have difficulty swallowing and require alternative nutritional support. Providing supplements via a nasogastric tube allows for the delivery of essential nutrients directly into the stomach, bypassing the swallowing difficulties. NPO (nothing by mouth) until dysphagia subsides may be too restrictive for the client's nutritional needs. Initiation of total parenteral nutrition is usually reserved for cases where enteral feeding is not possible or contraindicated. A soft residue diet may not be suitable for a client experiencing severe dysphagia.

3. What describes a criterion used to diagnose diabetes?

• A. a plasma glucose concentration of 100 mg/dL or higher after a fast of at least 12 hours
• B. a casual blood sample of 200 mg/dL or higher in a person with classic symptoms
• C. a plasma glucose concentration measured two hours after a 200-gram glucose load is 400 mg/dL or higher
• D. a HbA1C higher than 5 percent

Correct answer: B

Rationale: A casual blood sample of 200 mg/dL or higher in a person with classic symptoms is a diagnostic criterion for diabetes. This choice aligns with the typical clinical presentation of diabetes and is a key diagnostic indicator. Choices A, C, and D do not accurately reflect the established criteria for diagnosing diabetes, making them incorrect. Choice A pertains to a fasting plasma glucose level, Choice C involves a glucose challenge test, and Choice D refers to HbA1C levels, which are used for monitoring blood sugar control over time, not for diagnosing diabetes.

4. An imbalance of which nutrient may elicit delayed tooth eruption, enlarged tongue, stillbirths, altered craniofacial growth, sensitivity to cold, dry skin, depression, and goiter?

• A. Zinc
• B. Iron
• C. Sodium
• D. Potassium

Correct answer: B

Rationale: The correct answer is B: Iron. The provided extract mentions that iodine deficiency can cause delayed tooth eruption, enlarged tongue, stillbirths, altered craniofacial growth, sensitivity to cold, dry skin, depression, and goiter. Zinc, Sodium, and Potassium are not associated with these specific symptoms. Zinc deficiency can lead to other health issues but not the ones mentioned. Sodium and Potassium imbalances do not typically result in the symptoms described in the question.

5. Which monosaccharide is the most sweet?

• A. Glucose
• B. Dextrose
• C. Fructose
• D. Sucrose

Correct answer: C

Rationale: Fructose is the sweetest of the monosaccharides. Note that glucose and dextrose are the same, and sucrose is a disaccharide, not a monosaccharide.
