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. The nurse is teaching the client diagnosed with colon cancer who is scheduled for a colostomy the next day. Which behavior indicates the best method of applying adult teaching principles?
- A. The nurse repeats the information as indicated by the client’s questions
- B. The nurse teaches all the information needed by the client in one session
- C. The nurse uses a video to explain with medical terms to the client
- D. The nurse waits until the client asks questions about the surgery
Correct answer: A
Rationale: Choice A is the best method of applying adult teaching principles because repeating information and addressing the client’s questions as they arise is effective for reinforcing learning in adults. This approach allows for clarification of doubts and ensures that the client understands the information provided. Choice B is incorrect as teaching all the information in one session may overwhelm the client and hinder retention. Choice C is incorrect as using medical terms without ensuring the client's understanding may lead to confusion. Choice D is incorrect because waiting for the client to ask questions may result in missed opportunities to address important information proactively.
3. Who typically collects blood specimens?
- A. The nurse
- B. Medical technologist
- C. Physician
- D. Phlebotomist
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. Physicians are not commonly involved in the direct collection of blood specimens. While phlebotomists are specialized professionals trained to draw blood, in many medical settings, nurses perform this task as part of their responsibilities.
4. Which laboratory data indicate the client’s pancreatitis is improving?
- A. The amylase and lipase serum levels are decreased
- B. The white blood cell count (WBC) is decreased
- C. The conjugated and unconjugated bilirubin levels are decreased
- D. The blood urea nitrogen (BUN) serum level is decreased
Correct answer: A
Rationale: The correct answer is A. Amylase and lipase are specific markers for pancreatitis. A decrease in their serum levels indicates improvement in pancreatitis. Choice B, a decreased white blood cell count (WBC), is more indicative of an improvement in infection rather than pancreatitis. Choices C and D, decreased bilirubin levels and blood urea nitrogen (BUN) levels respectively, are not specific markers for pancreatitis improvement.
5. After attempting suicide by taking 200 acetaminophen (Tylenol) tablets, a client is transferred from the emergency department to the locked psychiatric unit. The client is now awake and alert but refuses to speak with the nurse. In this situation, what is the nurse’s first priority?
- 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: The nurse's first priority in this situation is to ensure the client's safety by initiating suicide precautions. This involves removing any potential means of self-harm and closely monitoring the client to prevent further attempts. While establishing rapport and communication are important, safety is paramount at this critical juncture. Placing the client in full restraints should be avoided unless absolutely necessary for immediate safety concerns.
