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

• A. Platelets
• B. Vitamin K
• C. Calcium
• D. Vitamin B12

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. Why may patients with hiatal hernia develop anemia?

• A. Iron absorption is reduced
• B. Gastritis may cause bleeding
• C. Iron stores turn over more quickly
• D. Patients have an aversion to foods that are good sources of iron

Correct answer: B

Rationale: The correct answer is B: Gastritis may cause bleeding. In patients with hiatal hernia, gastritis can lead to gastrointestinal bleeding, resulting in anemia due to blood loss. Choice A is incorrect because hiatal hernia does not directly affect iron absorption. Choice C is incorrect as iron stores turning over more quickly is not a typical reason for anemia in hiatal hernia patients. Choice D is incorrect as an aversion to iron-rich foods does not directly cause anemia in this context.

3. A patient taking anticoagulants should be cautious about consuming which type of food?

• A. High-protein foods
• B. High-fiber foods
• C. High-vitamin K foods
• D. High-calcium foods

Correct answer: C

Rationale: The correct answer is C: High-vitamin K foods. Foods high in vitamin K can interfere with the effectiveness of anticoagulants. Vitamin K plays a crucial role in blood clotting, so consuming high amounts of it can counteract the anticoagulant effects. Choices A, B, and D are incorrect as they do not directly interfere with the action of anticoagulants.

4. Enteral feedings may be appropriate for patients with:

• A. Acute cholecystitis
• B. Hepatic encephalopathy
• C. Ulcerative colitis in remission
• D. Acute exacerbation of Crohn’s disease

Correct answer: D

Rationale: Enteral feedings are commonly utilized for patients experiencing acute exacerbations of Crohn’s disease to provide necessary nutrition and rest the bowel. Choices A, B, and C are incorrect because enteral feedings are not typically indicated for acute cholecystitis, hepatic encephalopathy, or ulcerative colitis in remission.

5. Whenever possible, patients evacuated from the theater of operations who are expected to return within 60 days are admitted to which of the following?

• A. Civilian hospitals participating in the National Disaster Medical System
• B. DOD tri-service hospitals
• C. Department of Veterans Affairs hospitals
• D. Temporary field hospitals

Correct answer: B

Rationale: Patients evacuated from the theater of operations and expected to return within 60 days are admitted to DOD tri-service hospitals. These hospitals are well-equipped to handle military personnel and are strategically placed for operational efficiency. Choice A, civilian hospitals participating in the National Disaster Medical System, may not have the specialized care and resources required for military personnel. Choice C, Department of Veterans Affairs hospitals, cater to veterans rather than active-duty personnel in theater. Choice D, temporary field hospitals, might not provide the comprehensive care and resources needed for an extended period of treatment.
