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. Mrs. Seva also tells the nurse that she is often constipated. Because she is aging, what physical changes predispose her to constipation?

• A. inhibition of the parasympathetic reflex
• B. weakness of sphincter muscles of anus
• C. loss of tone of the smooth muscles of the colon
• D. decreased ability to absorb fluids in the lower intestines

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

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. You will give health instructions to Carlo, a case of bronchial asthma. The health instruction will include the following, EXCEPT:

• A. Avoid emotional stress and extreme temperature
• B. Avoid pollution like smoking
• C. Avoid pollens, dust, seafood
• D. Practice respiratory isolation

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

5. Is the loss of teeth or supporting periodontium often associated with poor food selection and limited chewing ability, and do the patients' masticatory efficiency and biting force decline with each tooth lost?

• 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 indeed true. The loss of teeth or supporting periodontium frequently leads to poor food selection and limited chewing ability, as these conditions can make certain foods difficult to consume. Additionally, a patient's masticatory efficiency and biting force do decline with each tooth lost, as there are fewer teeth to distribute the force of the bite. Choices B, C, and D are incorrect because they suggest that one or both of these statements are false, which is not the case.
