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. When a patient is prescribed an oral anticoagulant, what should the nurse monitor for?

• A. Elevated blood glucose
• B. Decreased blood pressure
• C. Signs of bleeding
• D. Increased appetite

Correct answer: C

Rationale: When a patient is prescribed an oral anticoagulant, the nurse should monitor for signs of bleeding. Oral anticoagulants work by inhibiting the blood's ability to clot, which increases the risk of bleeding. Monitoring for signs of bleeding such as easy bruising, petechiae, hematuria, or bleeding gums is crucial to prevent complications. Elevated blood glucose (Choice A) is not directly related to oral anticoagulant use. Decreased blood pressure (Choice B) is not a common effect of oral anticoagulants. Increased appetite (Choice D) is not a typical side effect of oral anticoagulants and is not a primary concern when monitoring a patient on this medication.

3. A family came to the emergency department with complaints of food poisoning. Which client should the nurse see first?

• A. 32-year-old with diarrhea for 6 hours
• B. 2-year-old with 1 wet diaper in 24 hours
• C. 40-year-old with abdominal cramping
• D. 10-year-old who is nauseated

Correct answer: B

Rationale: The correct answer is B because a 2-year-old with reduced urine output (1 wet diaper in 24 hours) is at high risk for dehydration. Dehydration can occur rapidly in young children and can be life-threatening. The nurse should prioritize assessing and managing the dehydration of the 2-year-old. Choices A, C, and D, although they may also require attention, do not present the same level of immediate risk as a dehydrated 2-year-old.

4. Which of the following nursing interventions is important for a client scheduled to have a Guaiac Test?

• A. Avoid turnips, radish, and horseradish 3 days before
• B. Continue iron preparation to prevent further loss
• C. Do not consume meat 12 hours before the procedure
• D. Encourage consumption of caffeine and dark-colored foods

Correct answer: A

Rationale: The correct answer is A. Turnips, radish, and horseradish are known to cause false-positive results in a Guaiac Test, which is used to detect blood in the stool. Avoiding these foods is crucial to ensure accurate test results. Choice B is incorrect as iron preparation is not directly related to the Guaiac Test. Choice C is incorrect because avoiding meat is not specifically necessary before a Guaiac Test. Choice D is incorrect as caffeine and dark-colored foods can potentially interfere with test results, so they should not be encouraged.

5. The nurse enters a client’s room and the client is demanding release from the hospital. The nurse reviews the client’s record and notes that the client was admitted 2 days ago for treatment of an anxiety disorder, and the admission was voluntary. Which intervention should the nurse initiate first?

• A. Telephone the client’s family and have them persuade the client to stay
• B. Have the client read and sign all the appropriate self-discharge papers
• C. Explain to the client that he cannot leave because he asked for treatment
• D. Notify the client’s healthcare provider of the client’s stated intent to leave the hospital

Correct answer: D

Rationale: The correct intervention for the nurse to initiate first is to notify the client’s healthcare provider of the client’s intention to leave the hospital. This is important to ensure that the client’s care and safety are appropriately managed. Option A is incorrect as involving the family without proper assessment or intervention could violate the client's autonomy. Option B is incorrect because it does not involve the healthcare provider in the decision-making process. Option C is incorrect as it does not address the client's rights to make decisions about their own care.
