Nursing Elites

1. Which of the following lab values indicates a patient on warfarin is at a therapeutic level?

• A. INR of 1.1
• B. PT of 12 seconds
• C. INR of 2.5
• D. Platelet count of 150,000

Correct answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

2. A nurse is providing discharge teaching to a client who has a new prescription for lithium. Which of the following instructions should the nurse include?

• A. Take this medication on an empty stomach.
• B. Avoid eating foods that contain tyramine.
• C. Drink at least 2 liters of water each day.
• D. Take this medication in the evening before bedtime.

Correct answer: C

Rationale: The correct instruction for a client prescribed lithium is to drink at least 2 liters of water each day. This is important to prevent dehydration and reduce the risk of lithium toxicity. Option A is incorrect because lithium is usually taken with food to minimize gastrointestinal side effects. Option B is unrelated to lithium and is more applicable to clients taking MAOIs. Option D is incorrect as lithium is typically taken in divided doses throughout the day to maintain therapeutic levels.

3. A healthcare professional is reviewing a client's laboratory results. Which of the following values is a contraindication to the administration of heparin?

• A. Hemoglobin 13 g/dL
• B. Platelet count 50,000/mm³
• C. White blood cell count 6,000/mm³
• D. INR 2.5

Correct answer: B

Rationale: The correct answer is B: Platelet count 50,000/mm³. A platelet count of 50,000/mm³ increases the risk of bleeding, making heparin contraindicated. Platelets are essential for blood clotting, and a low count can lead to excessive bleeding. Choices A, C, and D are not contraindications to heparin administration. Hemoglobin level of 13 g/dL is within the normal range, white blood cell count of 6,000/mm³ is also normal, and an INR of 2.5 is within the therapeutic range for patients receiving heparin therapy.

4. What is the appropriate nursing response when a patient refuses blood transfusion due to religious beliefs?

• A. Respect the patient's decision and notify the provider
• B. Attempt to persuade the patient to accept the transfusion
• C. Document the refusal and notify the healthcare provider
• D. Provide education on the benefits of blood transfusion

Correct answer: A

Rationale: The correct answer is A: "Respect the patient's decision and notify the provider." When a patient refuses a blood transfusion due to religious beliefs, it is essential to respect their autonomy and religious beliefs. Attempting to persuade the patient (Choice B) goes against the principle of respect for autonomy and can lead to ethical dilemmas. Documenting the refusal and notifying the healthcare provider (Choice C) is important for legal and ethical purposes but should be preceded by respecting the patient's decision. Providing education on the benefits of blood transfusion (Choice D) may be appropriate in other situations but is not indicated when a patient refuses based on religious beliefs.

5. A nurse is caring for a client who has acute pancreatitis. Which of the following interventions should the nurse take?

• A. Encourage oral intake of clear liquids
• B. Administer an antiemetic before meals
• C. Insert a nasogastric tube for suction
• D. Place the client in a supine position

Correct answer: C

Rationale: In acute pancreatitis, the gastrointestinal tract needs to rest to reduce pancreatic enzyme secretion. Inserting a nasogastric tube for suction helps decompress the stomach and reduce stimulation of the pancreas. Encouraging oral intake of clear liquids (Choice A) or administering an antiemetic before meals (Choice B) may aggravate the condition by stimulating the pancreas. Placing the client in a supine position (Choice D) may not directly address the underlying issue of reducing pancreatic stimulation.
