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. Which intervention should the nurse implement for the client who has an ileal conduit?

• A. Pouch the stoma with a one-inch margin around the stoma
• B. Refer the client to the United Ostomy Association for discharge teaching
• C. Report to the healthcare provider any decrease in urinary output
• D. Monitor the stoma for signs and symptoms of infection every shift

Correct answer: C

Rationale: The correct intervention for a client with an ileal conduit is to report to the healthcare provider any decrease in urinary output. A decrease in urinary output can be indicative of a blockage or other complication, necessitating immediate attention. Choice A is incorrect because pouching the stoma with a margin around it is not directly related to managing complications. Choice B is incorrect as referring the client to an ostomy association may be beneficial for education but is not the immediate action needed for decreased urinary output. Choice D is incorrect because monitoring for infection, although important, is not the priority when dealing with a potential complication like decreased urinary output.

3. The nurse understands that which characteristics are of anthrax? Select all that apply.

• A. Cutaneous lesions become a black eschar and flu-like symptoms are a sign of pulmonary anthrax
• B. Cutaneous lesions become a black eschar
• C. Gastrointestinal anthrax causes blood anthrax
• D. Flu-like symptoms are a sign of pulmonary anthrax

Correct answer: A

Rationale: The correct characteristics of anthrax are that cutaneous anthrax causes black eschar lesions, and flu-like symptoms are typical of pulmonary anthrax. Choice B is incorrect because it only includes information about cutaneous anthrax lesions but doesn't cover the flu-like symptoms of pulmonary anthrax. Choice C is incorrect as gastrointestinal anthrax does not cause 'blood anthrax,' it causes symptoms like severe abdominal pain, vomiting, and diarrhea. Choice D is incorrect as flu-like symptoms are associated with pulmonary anthrax, not with gastrointestinal anthrax.

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. Which vitamin deficiency is commonly associated with prolonged antibiotic use?

• A. Vitamin A
• B. Vitamin B6
• C. Vitamin C
• D. Vitamin K

Correct answer: D

Rationale: The correct answer is Vitamin K. Prolonged antibiotic use can disrupt the gut flora, which is responsible for synthesizing Vitamin K. This disruption can lead to a Vitamin K deficiency and an increased risk of bleeding. Vitamin A, B6, and C deficiencies are not typically associated with prolonged antibiotic use.
