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. What is the initial major sign of acute renal failure?

• A. Oliguria
• B. Hematuria
• C. Proteinuria
• D. Glycosuria

Correct answer: A

Rationale: Oliguria, or reduced urine output, is often the initial major sign of acute renal failure. This reduction in urine output indicates that the kidneys are not functioning properly. Hematuria (blood in urine), proteinuria (presence of protein in urine), and glycosuria (presence of glucose in urine) are not typically the initial major signs of acute renal failure. While they may be present in certain conditions, oliguria is the most common and critical indicator of acute renal failure.

3. Which of the following actions would be of highest priority with regards to the external shunt?

• A. Avoid taking blood pressure or blood sample from the arm with the shunt
• B. Instruct the patient not to exercise the arm with the shunt
• C. Heparinize the shunt daily
• D. Change the dressing of the shunt daily

Correct answer: C

Rationale: Heparinizing the shunt daily (choice C) is the highest priority action as it prevents the formation of blood clots that can occlude the shunt, leading to potential complications such as thrombosis. Avoiding taking blood pressure or blood samples from the arm with the shunt (choice A) is also important, but secondary to heparinizing the shunt. Similarly, instructing the patient not to exercise the arm with the shunt (choice B) can help prevent unnecessary strain on the shunt, but it is not as critical as preventing clot formation. Changing the dressing of the shunt daily (choice D) is a standard nursing care practice to prevent infection, but again, it is not as critical as ensuring the shunt remains patent through daily heparinization.

4. A nurse is reviewing blood glucose values for a client who is at risk for Diabetes Mellitus. Which of the following findings should the nurse report to the provider?

• A. 2-hour glucose tolerance test level 150 mg/dL
• B. Fasting blood glucose 70 mg/dL
• C. Glycosylated hemoglobin 5%
• D. Casual blood glucose 90 mg/dL

Correct answer: A

Rationale: The correct answer is A. A 2-hour glucose tolerance test level of 150 mg/dL is above the normal range and should be reported to the provider as it indicates impaired glucose tolerance. Choice B (Fasting blood glucose 70 mg/dL) is within the normal range. Choice C (Glycosylated hemoglobin 5%) is also within the normal range. Choice D (Casual blood glucose 90 mg/dL) is within the normal range and does not indicate impaired glucose tolerance.

5. The oral cavity is the site of a wide variety of systemic disease manifestations due to:

• A. Rapid cellular turnover
• B. Constant attack by microorganisms
• C. Trauma-intense environment
• D. All of the above

Correct answer: D

Rationale: The oral cavity is indeed the site of various systemic disease manifestations due to multiple factors. Firstly, the rapid cellular turnover in the oral mucosa makes it susceptible to diseases. Secondly, the constant presence of microorganisms in the oral cavity contributes to the development of systemic diseases. Finally, the oral cavity being a trauma-intense environment further increases the risk of systemic manifestations. Therefore, all the provided options - rapid cellular turnover, constant attack by microorganisms, and a trauma-intense environment - play a role in making the oral cavity a site for various systemic diseases. Hence, the correct answer is 'All of the above.' Choices A, B, and C are incorrect individually as they each represent only one aspect of why the oral cavity is prone to systemic disease manifestations, whereas the correct answer encompasses all these factors.
