1. Warfarin (Coumadin) is an anticoagulant and interferes with the action of:

Correct answer: B

Rationale: The correct answer is B: Vitamin K. Warfarin inhibits the action of vitamin K, which is essential for blood clotting. By interfering with the production of certain clotting factors, warfarin helps prevent blood clots. Choices A, C, and D are incorrect because warfarin primarily affects the vitamin K-dependent clotting factors and not platelets, calcium, or vitamin B12.

2. The unlicensed nursing assistant is applying elastic compression stockings to the client. Which action by the assistant warrants immediate intervention by the nurse?

Correct answer: A

Rationale: The correct answer is A because compression stockings should be applied while the client is lying down to prevent pooling of blood in the legs, which can occur when the client is sitting or standing. Choice B is not a cause for immediate intervention as inserting two fingers under the proximal end of the stocking helps ensure proper fit. Choice C demonstrates the correct technique of elevating the feet while lying down to put on the stockings. Choice D also shows good care by making sure the toes were warm after putting the stockings on.

3. Where do most peptic ulcers occur?

Correct answer: C

Rationale: Most peptic ulcers occur in the duodenum, particularly in cases of duodenal ulcers. The correct answer is the duodenum because it is the most common site for peptic ulcers to develop. Peptic ulcers rarely occur in the esophagus and jejunum, making choices A, B, and D incorrect.

4. Short-bowel syndrome usually occurs when:

Correct answer: B

Rationale: Short-bowel syndrome usually occurs when more than 50% of the small intestine is surgically removed. This condition results in malabsorption of nutrients and fluids due to the reduced length of the small intestine. Choice A is incorrect because the contraction of longitudinal muscles does not lead to short-bowel syndrome. Choice C is incorrect as short-bowel syndrome is primarily related to the small intestine, not the large intestine. Choice D is incorrect since decreased transit time due to infection or drugs is not a direct cause of short-bowel syndrome.

5. Which lipoprotein carries cholesterol from tissues to the liver for excretion?

Correct answer: D

Rationale: The correct answer is D, High-density lipoprotein (HDL). HDL is known as 'good' cholesterol because it helps transport excess cholesterol from tissues back to the liver for removal from the body. Very low-density lipoprotein (VLDL) (choice A) and intermediate-density lipoprotein (choice B) are involved in transporting triglycerides. Low-density lipoprotein (LDL) (choice C) is known as 'bad' cholesterol as it can deposit cholesterol in the walls of arteries.
