Nursing Elites

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. Who is at higher risk for drug-nutrient interactions?

• A. Infants
• B. People with diabetes
• C. Women of childbearing age
• D. Older men and women

Correct answer: D

Rationale: Older men and women are at higher risk for drug-nutrient interactions due to factors such as polypharmacy and physiological changes. Polypharmacy, common in older adults, increases the likelihood of interactions between drugs and nutrients. Physiological changes that occur with aging can affect how drugs and nutrients are absorbed, distributed, metabolized, and excreted in the body. Infants, people with diabetes, and women of childbearing age are not typically considered high-risk groups for drug-nutrient interactions compared to older adults.

3. In a routine sputum analysis, which of the following indicates proper nursing action before sputum collection?

• A. Secure a clean container
• B. Discard the container if the outside becomes dirty
• C. Rinse the client's mouth with Listerine before collection
• D. Tell the client that 4 tablespoons of sputum are needed

Correct answer: A

Rationale: The correct answer is to secure a clean container before sputum collection. This is essential to prevent contamination of the specimen, ensuring accurate test results and avoiding the introduction of external particles or bacteria. Choice B is incorrect because discarding the container if the outside becomes dirty is not necessary; the cleanliness of the inside is crucial. Choice C is incorrect as rinsing the client's mouth with Listerine before collection may introduce unwanted substances that can affect the test results. Choice D is incorrect as the amount of sputum required can vary depending on the test, and specifying a specific amount without medical guidance is not appropriate.

4. The Army Medical Department has four major functions. Three are prevention, treatment, and evacuation. What is the fourth?

• A. Preparation
• B. Training
• C. Mobilization
• D. Selection

Correct answer: C

Rationale: The correct answer is C, 'Mobilization.' In the context of the Army Medical Department, mobilization refers to the process of preparing and organizing medical personnel and resources for deployment during military operations. While preparation, training, and selection are important functions within the military medical field, mobilization specifically relates to the readiness and deployment of medical assets in response to operational requirements, making it the fourth major function of the Army Medical Department.

5. Who typically collects blood specimens?

• A. The nurse
• B. Medical technologist
• C. Physician
• D. Pharmacist

Correct answer: A

Rationale: Nurses typically collect blood specimens from patients as part of their everyday duties in medical settings. They are trained in venipuncture techniques and are responsible for ensuring that blood samples are properly obtained and labeled for diagnostic testing. Medical technologists process and analyze the blood specimens in the laboratory under the direction of a physician, but the actual collection of specimens is commonly performed by nurses. Physicians are primarily responsible for diagnosing and treating medical conditions rather than collecting blood specimens. Pharmacists are healthcare professionals who specialize in medication management and dispensing, not in collecting blood specimens.
