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

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. What is the function of villi and microvilli in the GI tract?

Correct answer: D

Rationale: Villi and microvilli in the GI tract serve to increase the surface area of the small intestine, aiding in the absorption of nutrients into the bloodstream. Choices A, B, and C are incorrect as villi and microvilli are primarily involved in enhancing absorption, not in producing bile, killing bacteria, or producing vitamin K.

3. While on Bryant’s traction, which of these observations of Graciela and her traction apparatus would indicate a decrease in the effectiveness of her traction?

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

4. The substance that is most supportive of bones and teeth is:

Correct answer: B

Rationale: Collagen is a key structural protein in bones and teeth, providing support and strength.

5. What symptoms would most likely be associated with a transient ischemic attack?

Correct answer: A

Rationale: The correct answer is A: confusion and difficulty speaking. These symptoms are commonly associated with a transient ischemic attack (TIA), which is a temporary blockage of blood flow to the brain. Choice B, headache and blurred vision, are more indicative of other conditions such as migraines or eye problems. Choice C, chest pain and pressure, are more characteristic of cardiac issues like a heart attack. Choice D, claudication and peripheral edema, are typical of peripheral arterial disease and not typically seen in TIAs.
