Nursing Elites

1. A patient prescribed warfarin is being taught about dietary restrictions by a healthcare provider. Which of the following foods should the patient be instructed to limit?

• A. Bananas
• B. Spinach
• C. Potatoes
• D. Apples

Correct answer: B

Rationale: The correct answer is B: Spinach. Spinach is high in vitamin K, which can interfere with the effectiveness of warfarin, an anticoagulant medication. Patients taking warfarin should limit foods high in vitamin K to maintain the medication's effectiveness and consistent dosage. Bananas, potatoes, and apples are not high in vitamin K and do not typically interfere with warfarin therapy.

2. A healthcare provider is caring for a client who has an indwelling urinary catheter. Which of the following assessment findings indicates that the catheter requires irrigation?

• A. Bladder scan shows 525 mL
• B. Absent urinary output for 1 hour
• C. Cloudy urine
• D. Bloody urine

Correct answer: A

Rationale: The correct answer is A. A large bladder scan result (525 mL) suggests catheter blockage and may require irrigation to resolve. Choice B (absent urinary output for 1 hour) could indicate a different issue such as urinary retention but does not specifically indicate the need for catheter irrigation. Choices C (cloudy urine) and D (bloody urine) may suggest infection or other urinary issues, but they do not directly indicate the need for catheter irrigation.

3. Which of the following is a correct method of safely using a sterile dressing?

• A. Reuse a dressing that appears clean.
• B. Discard a dressing after 24 hours of use.
• C. Change a dressing only if there is visible drainage.
• D. Change a dressing every 4 hours regardless of condition.

Correct answer: B

Rationale: The correct method of safely using a sterile dressing is to discard it after 24 hours of use. This is important to prevent contamination and promote proper wound healing. Choice A is incorrect because reusing a dressing, even if it appears clean, can introduce contaminants. Choice C is incorrect as dressing changes should not be based solely on visible drainage; they should be done within the recommended time frame. Choice D is incorrect because changing a dressing every 4 hours, regardless of its condition, can lead to unnecessary wastage and disturbance to the wound healing process.

4. What should be done to manage a patient with contact precautions?

• A. Wear a mask, gown, and gloves for all patient interactions.
• B. Ensure that visitors wear protective equipment.
• C. Dedicate all patient care equipment to that patient.
• D. Disinfect shared equipment before use.

Correct answer: C

Rationale: When managing a patient with contact precautions, it is essential to dedicate all patient care equipment to that specific patient. This practice helps minimize the risk of spreading infections to other patients. Choice A, wearing protective gear for all patient interactions, is a general precaution but not specific to managing a patient with contact precautions. Choice B, ensuring visitors wear protective equipment, is important for infection control but not directly related to managing the patient with contact precautions. Choice D, disinfecting shared equipment before use, is a good practice for infection control in general but does not address the specific needs of a patient under contact precautions.

5. What are the main differences between a stroke caused by ischemia and one caused by hemorrhage?

• A. Blockage in a blood vessel supplying the brain
• B. Bleeding in the brain due to a ruptured aneurysm
• C. Administering thrombolytics if within the treatment window
• D. Avoiding anticoagulants and preparing for surgery

Correct answer: A

Rationale: The correct answer is A: "Blockage in a blood vessel supplying the brain." Ischemic stroke is caused by a blockage in a blood vessel supplying the brain, leading to reduced blood flow. Hemorrhagic stroke, on the other hand, is caused by bleeding in the brain due to a ruptured blood vessel. Choices B, C, and D are incorrect. Administering thrombolytics, avoiding anticoagulants, and preparing for surgery are specific management strategies that may apply to ischemic or hemorrhagic strokes but do not define the main differences between the two types of strokes.
