Nursing Elites

1. Intrinsic factor from the stomach is needed for the absorption of which vitamin?

• A. vitamin B12
• B. folate
• C. niacin
• D. vitamin B6

Correct answer: A

Rationale: The correct answer is A: vitamin B12. Intrinsic factor is a glycoprotein produced by the stomach that is necessary for the absorption of vitamin B12 in the small intestine. Vitamin B12 binds to intrinsic factor in the stomach, forming a complex that is then absorbed in the ileum. This absorption process is crucial for preventing vitamin B12 deficiency. Choices B, C, and D are incorrect because they do not require intrinsic factor for absorption. Folate is absorbed in the small intestine through a different mechanism, niacin can be absorbed in the small intestine without the need for intrinsic factor, and vitamin B6 does not rely on intrinsic factor for absorption.

2. High intakes of which of the following interfere with copper absorption and can lead to a deficiency?

• A. chromium
• B. sodium
• C. zinc
• D. manganese

Correct answer: C

Rationale: The correct answer is C, zinc. High intakes of zinc can interfere with copper absorption, potentially leading to copper deficiency. Copper is essential for various bodily functions, including iron metabolism. Choice A, chromium, is incorrect because chromium does not interfere with copper absorption. Choice B, sodium, and Choice D, manganese, are also incorrect as they do not interfere with copper absorption.

3. A nurse that is always ready to answer for all his actions and decision is said to be:

• A. Accountable C. Critical thinker
• B. Responsible D. Assertive
• C.
• D.

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

4. What are the potential consequences of damage to the stomach?

• A. Reduced digestion of carbohydrates
• B. Inability to produce or secrete bile
• C. Inability to produce or secrete gastric acid
• D. Increased ability to produce or secrete intrinsic factor

Correct answer: C

Rationale: Damage to the stomach can lead to a reduced ability to produce gastric acid (Choice C) and intrinsic factor, the latter of which is crucial for vitamin B12 absorption (Choice D). That's why these two choices are correct. The stomach doesn't play a direct role in the digestion of carbohydrates (Choice A) as this process primarily occurs in the small intestine with the help of pancreatic enzymes. Similarly, bile is produced by the liver and stored in the gallbladder, not the stomach, hence stomach damage wouldn't lead to an inability to produce or secrete bile (Choice B).

5. What is the primary goal of a dental hygienist when making dietary recommendations for a patient with a new dental prosthesis?

• A. To promote healing and repair by ensuring an adequate and nutrient-dense diet
• B. To promote healing and repair by recommending consumption of only liquids for the first week
• C. To promote a balanced diet by recommending a variety of fibrous foods
• D. To encourage the patient to become accustomed to the prosthesis by eating as usual

Correct answer: A

Rationale: The primary goal of a dental hygienist when making dietary recommendations for a patient with a new dental prosthesis is to promote healing and repair. This can be achieved by ensuring the patient maintains an adequate and nutrient-dense diet. This is why option 'A' is the correct answer. Option 'B' is incorrect because while liquids are easier to consume with a new dental prosthesis, a diet consisting only of liquids for a week may not provide all necessary nutrients. Option 'C' is incorrect because while a variety of fibrous foods can contribute to a healthy diet, it's not specifically relevant to the healing and adjustment to a new dental prosthesis. Option 'D' is incorrect because eating as usual may not be feasible or comfortable for a patient with a new prosthesis, and it doesn't specifically focus on promoting healing and repair.
