1. 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.

2. Studies suggest that leukoplakia is resolved by excess vitamin A (a fat-soluble vitamin), retinoids, and beta-carotene. Leukoplakia is a white plaque that forms on oral mucous membranes.

• A. Both statements are true.
• B. Both statements are false.
• C. The first statement is true; the second is false.
• D. The first statement is false; the second is true.

Correct answer: B

Rationale: Both statements are false. Studies suggest that leukoplakia, a white plaque that forms on oral mucous membranes, can be resolved by vitamin A, retinoids, and beta-carotene. Despite the potential to resolve leukoplakia, relapse is common. Also pertinent, evidence does not indicate that any of these nutrients prevent malignant transformation. The extract provided clarifies that leukoplakia is a white plaque, not an erythematous lesion, and that vitamin A, retinoids, and beta-carotene can help resolve it.

3. Which is the best description of a full-liquid diet?

• A. Most suitable for individuals with an ileostomy
• B. Suitable for individuals with lactose intolerance
• C. Contains low saturated fat and high fiber
• D. Provides adequate nutrients and is easily digested

Correct answer: D

Rationale: The correct answer is D because a full-liquid diet is designed to provide adequate nutrients while being easily digested. Choices A and B are incorrect because a full-liquid diet is not specifically tailored for individuals with an ileostomy or lactose intolerance. Choice C is also incorrect as it describes characteristics that are not defining features of a full-liquid diet.

4. To ensure client safety before starting blood transfusions, the following are needed before the procedure can be done EXCEPT:

• A. take baseline vital signs
• B. warm the blood to room temperature for 30 minutes before administering the transfusion
• C. have two nurses verify client identification, blood type, unit number, and expiration date of blood
• D. get consent signed for blood transfusion

Correct answer: D

Rationale: To ensure client safety before starting blood transfusions, taking baseline vital signs, warming the blood to room temperature, and having two nurses verify client identification, blood type, unit number, and expiration date of blood are crucial steps. Consent for blood transfusion is required but is typically obtained before the procedure. The focus before the procedure should be on confirming the right client, blood product, and ensuring the blood is prepared correctly to minimize risks of transfusion reactions.

5. A nurse is reinforcing dietary teaching with a client who has vitamin A deficiency. Which of the following food choices should the nurse recommend as the best source of vitamin A?

• A. 1 small baked sweet potato
• B. 1 cup avocado
• C. 1 cup green beans
• D. 1 large apple

Correct answer: A

Rationale: The correct answer is A. Sweet potatoes are rich in beta-carotene, which the body converts into vitamin A, essential for vision and immune function. Avocado (choice B) is a good source of healthy fats but not high in vitamin A. Green beans (choice C) are nutritious but not a significant source of vitamin A. Apples (choice D) are low in vitamin A compared to sweet potatoes.
