1. 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.

2. The two members of the health care team who work closely to monitor drug-nutrient interactions are:

• A. Physician and nurse
• B. Physician and pharmacist
• C. Nurse and clinical dietitian
• D. Clinical dietitian and pharmacist

Correct answer: D

Rationale: Clinical dietitians and pharmacists work together to manage drug-nutrient interactions. They have the expertise to understand how medications and nutrients can interact in the body, potentially affecting the effectiveness of treatment. Physicians and nurses may be involved in patient care, but when it comes to monitoring drug-nutrient interactions, the specialized knowledge of clinical dietitians and pharmacists is crucial. Nurses and physicians typically focus more on administering medications and managing overall patient care, rather than the specific interactions between drugs and nutrients.

3. Which of the following describes a process of heat loss involving the transfer of heat from one surface to another?

• A. Radiation
• B. Conduction
• C. Convection
• D. Evaporation

Correct answer: B

Rationale: Conduction is the process of heat transfer that occurs between objects or substances that are in direct contact with each other. In this process, heat is transferred from a hotter surface to a cooler surface through direct contact. This type of heat transfer does not involve the movement of the substances themselves, only the transfer of thermal energy. Choice A, Radiation, is the transfer of heat in the form of electromagnetic waves and does not require a medium. Choice C, Convection, involves the transfer of heat through the movement of fluids (liquids or gases) due to density differences. Choice D, Evaporation, is a cooling process that involves the transformation of a liquid into a gas, absorbing heat in the process.

4. 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.

5. When does short-bowel syndrome usually occur?

• A. The longitudinal muscles of the intestine contract
• B. More than 50% of the small intestine is surgically removed
• C. More than 50% of the large intestine is surgically removed
• D. Transit time is decreased due to infection or drugs

Correct answer: B

Rationale: Short-bowel syndrome typically occurs when more than 50% of the small intestine is surgically removed. This condition leads to malabsorption issues due to the reduced length of the intestine for absorption. Choices A, C, and D are incorrect because short-bowel syndrome specifically relates to the insufficient length of the small intestine, not the contraction of longitudinal muscles, surgical removal of the large intestine, or decreased transit time due to infection or drugs.
