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. Which item is typically fortified with iodine to address iodine deficiency in the population?

• A. Flour
• B. Salt
• C. Canned vegetables
• D. Drinking water

Correct answer: B

Rationale: Iodized salt is the correct answer. Iodine deficiency can lead to thyroid problems, so iodine is added to salt to ensure an adequate intake of this essential nutrient. Flour is often fortified with other nutrients like folic acid, iron, and niacin, but not iodine. Canned vegetables and drinking water are not typically fortified with iodine to address deficiency in the population.

3. A patient tells the nurse “I am depressed to talk to you, leave me alone” Which of the following response by the nurse is most therapeutic?

• A. I’ll be back in an hour
• B. Why are you so depressed?
• C. I’ll seat with you for a moment
• D. Call me when you feel like talking to me

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.

4. What is the role of fat in digestion?

• A. Digest fats in the stomach
• B. Emulsify fats in the small intestine
• C. Transport fats through the circulatory system
• D. Split fats into smaller components

Correct answer: B

Rationale: The correct answer is B: Emulsify fats in the small intestine. Bile emulsifies fats in the small intestine, breaking them down into smaller droplets that can be more easily digested by enzymes like lipase. Choice A is incorrect as fats are not digested in the stomach but rather in the small intestine. Choice C is incorrect as fats are transported through the lymphatic system instead of the circulatory system. Choice D is incorrect as fats are broken down into smaller components through emulsification, not splitting.

5. Which is NOT a classification of carbohydrate?

• A. Monosaccharides
• B. Disaccharides
• C. Polysaccharides
• D. Triglycerides

Correct answer: D

Rationale: The correct answer is D, Triglycerides. Triglycerides are a type of fat, not a carbohydrate. Monosaccharides, disaccharides, and polysaccharides are all classifications of carbohydrates based on the number of sugar units they contain. Monosaccharides are the simplest form with one sugar unit, disaccharides contain two sugar units, and polysaccharides have multiple sugar units linked together.
