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. A client is receiving external beam radiation to the mediastinum for treatment of bronchial cancer. Which of the following should take priority in planning care?

• A. Esophagitis
• B. Leukopenia
• C. Fatigue
• D. Skin irritation

Correct answer: B

Rationale: The correct answer is B: Leukopenia. Leukopenia, or a low white blood cell count, is a critical concern in clients undergoing radiation therapy due to the increased risk of infection. While esophagitis, fatigue, and skin irritation are also potential side effects of radiation therapy, leukopenia poses a higher risk as it compromises the body's ability to fight infections effectively.

3. A client with deep vein thrombosis (DVT) is prescribed heparin. What lab value should the nurse monitor to assess the effectiveness of the therapy?

• A. Prothrombin time (PT).
• B. Partial thromboplastin time (PTT).
• C. International Normalized Ratio (INR).
• D. Hemoglobin and hematocrit.

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). PTT is the lab value used to monitor the effectiveness of heparin therapy in clients with DVT. It measures the intrinsic pathway of coagulation and is prolonged by heparin therapy. Prothrombin time (PT) and International Normalized Ratio (INR) are primarily used to monitor warfarin therapy, not heparin. Checking hemoglobin and hematocrit levels is important but does not directly assess the effectiveness of heparin therapy in DVT.

4. A nurse assesses a young adult in the emergency room following a motor vehicle accident. Which of the following neurological signs is of most concern?

• A. Flaccid paralysis
• B. Pupils fixed and dilated
• C. Diminished spinal reflexes
• D. Reduced sensory responses

Correct answer: B

Rationale: Fixed, dilated pupils are a sign of increased intracranial pressure or brain injury, indicating a potentially serious neurological condition. Flaccid paralysis, although concerning, may not always indicate immediate life-threatening issues. Diminished spinal reflexes and reduced sensory responses are important neurological assessments but are not as acutely concerning as fixed, dilated pupils in this context.

5. An adult client with a broken femur reports muscle spasms. What action should the nurse implement while awaiting surgery?

• A. Check the client's most recent electrolyte levels.
• B. Administer a PRN dose of muscle relaxant.
• C. Reduce the weight on the traction device.
• D. Encourage oral fluid intake to relieve muscle tension.

Correct answer: D

Rationale: The correct action for the nurse to implement while awaiting surgery for a client with muscle spasms due to a broken femur is to encourage oral fluid intake to relieve muscle tension. Dehydration can exacerbate muscle spasms, so increasing fluid intake can help alleviate them. Checking electrolyte levels may not directly address muscle spasms in this situation. Administering a muscle relaxant should be based on a healthcare provider's prescription, and traction weight adjustments should only be made by the provider overseeing the client's care.
