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 works by inhibiting the action of vitamin K, which is crucial for the synthesis of clotting factors in the blood. By interfering with vitamin K, warfarin decreases the production of these clotting factors, thereby prolonging the time it takes for blood to clot. This is why individuals on warfarin therapy need to monitor their vitamin K intake. Choices A, C, and D are incorrect because warfarin does not directly interfere with platelets, calcium, or vitamin B12.

2. The nurse administers 2 units of salt-poor albumin to a client with portal hypertension and ascites. The nurse explains to the client that this is administered to:

• A. Provide nutrients
• B. Increase protein stores
• C. Elevate the circulating blood volume
• D. Divert blood flow away from the liver temporarily

Correct answer: C

Rationale: The correct answer is C: Elevate the circulating blood volume. Salt-poor albumin is given to increase the circulating blood volume, which helps reduce ascites by improving fluid distribution within the body. Choices A, B, and D are incorrect because salt-poor albumin is not administered to provide nutrients, increase protein stores, or divert blood flow away from the liver.

3. A client is transferred from the emergency department to the locked psychiatric unit after attempting suicide by taking 200 acetaminophen (Tylenol) tablets. The client is now awake and alert but refuses to speak with the nurse. In this situation, the nurse’s first priority is to:

• A. Establish a rapport to foster trust
• B. Place the client in full restraints
• C. Try to communicate with the client in writing
• D. Ensure safety by initiating suicide precautions

Correct answer: D

Rationale: In this scenario, the nurse's highest priority should be to ensure the client's safety by initiating suicide precautions. Given the history of a suicide attempt by taking a large number of acetaminophen tablets, there is a high risk of further self-harm. Placing the client in full restraints without assessing the situation properly may escalate anxiety and hinder therapeutic communication. Trying to communicate with the client in writing could be an option but ensuring immediate safety takes precedence. Establishing rapport is essential for building trust and therapeutic relationship, but safety concerns must be addressed first in this critical situation.

4. 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.

5. What is the best position for any procedure that involves vaginal and cervical examination?

• A. Dorsal recumbent
• B. Side lying
• C. Supine
• D. Lithotomy

Correct answer: D

Rationale: The lithotomy position is the most suitable position for procedures involving vaginal and cervical examination because it provides the best access to the vaginal and cervical regions. In this position, the patient lies on their back with their legs flexed and feet placed in stirrups, allowing for optimal visualization and access to the area. This position facilitates proper examination, diagnosis, and treatment when working in the gynecological field. Choices A, B, and C are incorrect as they do not provide the necessary exposure and access required for a thorough vaginal and cervical examination. Dorsal recumbent, side lying, and supine positions may limit visibility and hinder the examination process in such cases.
