1. Which of the following statements is false?

• A. People with a vitamin K deficiency experience increased clotting time
• B. The major function of vitamin E is promoting vision
• C. Vitamin D functions as a hormone
• D. Rich sources of beta-carotene include carrots, sweet potatoes, and butternut squash

Correct answer: B

Rationale: The statement that the major function of vitamin E is promoting vision is incorrect. Vitamin E primarily acts as an antioxidant, protecting cells from oxidative damage. Its role is not primarily related to vision, which is a major function of vitamin A. On the other hand, the other options are true. Vitamin K deficiency does indeed lead to increased clotting time, vitamin D functions as a hormone, and carrots, sweet potatoes, and butternut squash are rich sources of beta-carotene.

2. 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.

3. What intervention would be most appropriate for a patient who has difficulty eating because of chewing problems?

• A. Use squeeze bottles to pour liquids into the mouth
• B. Provide utensils that have modified handles
• C. Offer plates with food guards
• D. Provide soft foods

Correct answer: D

Rationale: Providing soft foods is crucial for patients with chewing difficulties to ensure they can consume adequate nutrition without discomfort.

4. During which phase of the therapeutic relationship should the nurse inform the patient about the termination of therapy?

• A. Pre-orientation
• B. Orientation
• C. Working
• D. Termination

Correct answer: D

Rationale: The correct answer is 'Termination'. This phase of the therapeutic relationship is when the nurse informs the patient about the conclusion of therapy. It is during this phase that the nurse and the patient review the goals and progress made and also discuss the upcoming termination. The other phases are not the appropriate times for discussing termination. 'Pre-orientation' is the phase before the nurse-patient relationship is established; 'Orientation' is when the nurse and patient get to know each other and set goals; and 'Working' is when these goals are pursued. Therefore, choices A, B, and C are incorrect.

5. Approximately 75% of reputable producers of bottled water use groundwater as their water source. Plain tap water is the most natural source of fluids.

• 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: A

Rationale: Both statements are true. Approximately 75% of reputable producers of bottled water use groundwater as their water source, which is the same source as the public water supply. Plain tap water, coming from underground sources or reservoirs, is indeed a natural source of fluids. The first statement is supported by the fact that groundwater is a common source for bottled water due to its purity and taste. The second statement is true as tap water is sourced from natural reservoirs or underground aquifers in most cases, making it a natural fluid source for consumption. Other choices are incorrect because both statements are factually accurate based on common practices in the production and sourcing of bottled water and tap water.
