Nursing Elites

1. A client with a history of atrial fibrillation is prescribed warfarin. What is the nurse's priority teaching?

• A. Avoid eating foods high in potassium.
• B. Avoid foods high in vitamin K.
• C. Take the medication on an empty stomach.
• D. Take the medication at bedtime for best results.

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.

2. After completing her first chemotherapy treatment, what behavior indicates that a female client with breast cancer understands her discharge care needs?

• A. She refuses to take anti-nausea medication.
• B. She rents movies and borrows books to pass time at home.
• C. She plans to resume strenuous physical activity immediately.
• D. She reports severe fatigue and inability to perform daily activities.

Correct answer: B

Rationale: Renting movies and borrowing books for use during recovery indicates the client is planning restful activities at home, which aligns with appropriate post-chemotherapy care. Choices A, C, and D are incorrect because refusing anti-nausea medication can lead to complications, resuming strenuous physical activity immediately can be harmful, and reporting severe fatigue and inability to perform daily activities may indicate a need for medical attention rather than understanding discharge care needs.

3. A client is newly prescribed lithium for bipolar disorder. Which finding is most important to report to the healthcare provider?

• A. A serum lithium level of 1.2 mEq/L.
• B. Fine hand tremors noted after starting the medication.
• C. A blood pressure of 110/60 mmHg.
• D. A serum sodium level of 140 mEq/L.

Correct answer: B

Rationale: The correct answer is B. Fine hand tremors noted after starting lithium are an early sign of lithium toxicity. It is crucial to report this finding to the healthcare provider promptly. Adjusting the dose or monitoring serum levels more closely may be necessary to prevent further toxicity. Choice A, a serum lithium level of 1.2 mEq/L, is within the therapeutic range (0.6-1.2 mEq/L) for treating bipolar disorder. Choice C, a blood pressure of 110/60 mmHg, and Choice D, a serum sodium level of 140 mEq/L, are within normal limits and not directly related to lithium therapy or toxicity.

4. A client is scheduled for a spiral CT scan with contrast to evaluate for pulmonary embolism. Which information in the client's history requires follow-up by the nurse?

• A. Is allergic to shellfish
• B. Has a history of smoking
• C. Takes metformin for type 2 diabetes mellitus
• D. Has hypertension controlled with medication

Correct answer: A

Rationale: An allergy to shellfish often indicates an allergy to iodine, which is used in contrast dyes for CT scans. This poses a significant risk of an allergic reaction during the procedure. The nurse must ensure appropriate precautions or alternative imaging are considered. Choices B, C, and D are not directly contraindicated for a CT scan with contrast. Smoking history, metformin use, and controlled hypertension do not typically impact the safety or feasibility of the procedure.

5. A client with chronic kidney disease has a potassium level of 6.2 mEq/L. Which intervention should the nurse implement?

• A. Encourage the client to eat foods rich in potassium
• B. Administer a potassium-sparing diuretic
• C. Administer a potassium-binding medication
• D. Hold all medications containing potassium

Correct answer: C

Rationale: A potassium level of 6.2 mEq/L indicates hyperkalemia, which is dangerous and requires immediate treatment. Administering a potassium-binding medication will help lower potassium levels and prevent life-threatening complications.
