Nursing Elites

1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin) therapy. Which laboratory result indicates that the therapy is effective?

• A. International normalized ratio (INR) of 1.0.
• B. Prothrombin time (PT) of 12 seconds.
• C. Partial thromboplastin time (PTT) of 60 seconds.
• D. International normalized ratio (INR) of 2.5.

Correct answer: D

Rationale: An International Normalized Ratio (INR) of 2.5 indicates that warfarin therapy is within the therapeutic range for a client with atrial fibrillation. A lower INR (such as 1.0) would suggest subtherapeutic levels, risking blood clots. Prothrombin time (PT) and partial thromboplastin time (PTT) are not specific to monitoring warfarin therapy.

2. A client with a history of deep vein thrombosis (DVT) is admitted with unilateral leg swelling. Which intervention should the nurse implement?

• A. Elevate the affected leg on a pillow.
• B. Apply a warm compress to the affected leg.
• C. Perform passive range-of-motion exercises on the affected leg.
• D. Encourage the client to ambulate frequently.

Correct answer: A

Rationale: The correct intervention for a client with a history of deep vein thrombosis (DVT) and unilateral leg swelling is to elevate the affected leg on a pillow. Elevating the affected leg helps reduce swelling and pain by promoting venous return and preventing stasis of blood flow. Applying a warm compress (Choice B) may increase inflammation and worsen the condition. Performing passive range-of-motion exercises (Choice C) and encouraging ambulation (Choice D) can dislodge a clot and lead to potential embolism, making these choices contraindicated in a client with DVT.

3. The nurse is caring for a client with Addison's disease. Which finding requires immediate intervention?

• A. Hyperpigmentation of the skin.
• B. Low blood pressure.
• C. Nausea and vomiting.
• D. Hypoglycemia.

Correct answer: B

Rationale: Low blood pressure in a client with Addison's disease requires immediate intervention as it can indicate an Addisonian crisis, a life-threatening condition that necessitates prompt treatment. Hyperpigmentation of the skin is a characteristic finding in Addison's disease but does not require immediate intervention. Nausea and vomiting can be managed symptomatically in Addison's disease. While hypoglycemia needs attention, it is not the most critical finding requiring immediate intervention in this context.

4. While screening all children in the third grade for head lice, the school nurse observes that one girl has a brownish thickening on her neck. Which action should the nurse take in response to this finding?

• A. review the child's medical folder for a list of allergies
• B. instruct the child's parents to begin treatment
• C. advise the child's parents to obtain a medical evaluation of the child
• D. none of the above

Correct answer: C

Rationale: The correct action for the nurse to take is to advise the child's parents to obtain a medical evaluation of the child. This is important because a medical professional needs to properly diagnose and treat the brownish thickening observed on the child's neck. Reviewing the child's medical folder for allergies (Choice A) is not appropriate in this situation as it does not address the specific concern. Instructing the child's parents to begin treatment (Choice B) without a proper diagnosis can be harmful and ineffective. Choosing 'none of the above' (Choice D) is not the best option when a potential health issue is identified; seeking a medical evaluation is the most appropriate course of action.

5. The healthcare provider is caring for a client with a chest tube following thoracic surgery. Which intervention should the healthcare provider include in the plan of care?

• A. Clamp the chest tube for 30 minutes every 2 hours.
• B. Milk the chest tube to ensure patency.
• C. Keep the drainage system at the level of the chest.
• D. Ensure that the chest tube is not clamped or kinked.

Correct answer: D

Rationale: Ensuring that the chest tube is not clamped or kinked is essential to maintain proper drainage and prevent complications. Clamping the chest tube can lead to a buildup of pressure in the pleural space, causing potential harm to the client. Milking the chest tube is not recommended as it can cause damage to the delicate tubing. Keeping the drainage system at the level of the chest ensures proper drainage by gravity, preventing backflow of fluids, but ensuring the tube is not clamped or kinked takes precedence in this scenario.
