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. The nurse on the medical/surgical unit cares for a client with a diagnosis of cerebrovascular accident (CVA). The nursing assessment of the client’s neurological status should include which of the following? (Select all that apply)

• A. Obtain the pulses in all four extremities
• B. Ask the client to grasp and squeeze two fingers on each of the nurse’s hands
• C. Determine the client’s orientation to person, place, and time
• D. B, C

Correct answer: D

Rationale: The correct choices are B and C. Assessing grasp strength and orientation to person, place, and time are essential components of a neurological assessment after a CVA. Pulse assessment in all four extremities is more relevant to circulatory assessment rather than neurological status. Therefore, option A is incorrect.

3. Which drugs contribute to peptic ulcers?

• A. Antacids
• B. Certain antibiotics
• C. Cholesterol-lowering medications
• D. Nonsteroidal anti-inflammatory drugs

Correct answer: D

Rationale: Nonsteroidal anti-inflammatory drugs (NSAIDs) are known to contribute to the development of peptic ulcers by affecting the protective lining of the stomach and increasing stomach acid production. This can lead to irritation and ulcer formation. Antacids are actually used to relieve symptoms of peptic ulcers by neutralizing stomach acid. Certain antibiotics may be prescribed to treat H. pylori infection, a common cause of peptic ulcers. Cholesterol-lowering medications are not typically associated with causing peptic ulcers.

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 of iron
• C. Do not consume red meat 12 hours before the procedure
• D. Encourage consumption of dark-colored foods with caffeine

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 because iron preparations can interfere with the test results. Choice C is incorrect as red meat does not impact the Guaiac Test significantly. Choice D is incorrect as caffeine and dark-colored foods are not relevant to the preparation for a Guaiac Test.

5. A patient with diabetes should be advised to avoid which type of carbohydrate?

• A. Simple carbohydrates
• B. Complex carbohydrates
• C. Fiber-rich carbohydrates
• D. All carbohydrates

Correct answer: A

Rationale: The correct answer is A: Simple carbohydrates. Simple carbohydrates can cause rapid spikes in blood glucose levels, which can be problematic for patients with diabetes. These carbohydrates are quickly broken down and absorbed by the body, leading to sharp increases in blood sugar levels. In contrast, complex carbohydrates and fiber-rich carbohydrates are generally better choices for individuals with diabetes because they are digested more slowly, resulting in a more gradual rise in blood glucose levels. Choice B, complex carbohydrates, are a better option for diabetic patients compared to simple carbohydrates. Choice C, fiber-rich carbohydrates, can also be beneficial for individuals with diabetes as they help in regulating blood sugar levels. Choice D, all carbohydrates, is too broad of a statement as not all carbohydrates have the same impact on blood glucose levels.
