Nursing Elites

1. The nurse is assisting with the care of a client who is on a continuous heparin infusion for deep vein thrombosis (DVT). Which laboratory test should the nurse monitor to evaluate the effectiveness of the therapy?

• A. Prothrombin time (PT)
• B. Activated partial thromboplastin time (aPTT)
• C. International normalized ratio (INR)
• D. Platelet count

Correct answer: B

Rationale: To evaluate the effectiveness of heparin therapy in a client with DVT, the nurse should monitor the activated partial thromboplastin time (aPTT). The aPTT test helps ensure that the dose of heparin is within the therapeutic range, which is essential for preventing clot formation or excessive bleeding. Monitoring aPTT is crucial in managing patients on heparin therapy to maintain the delicate balance between preventing thrombosis and avoiding hemorrhage. Prothrombin time (PT) and International normalized ratio (INR) are more indicative of warfarin therapy effectiveness, not heparin. Platelet count assesses platelet levels and function, not the effectiveness of heparin therapy for DVT.

2. The nurse is preparing to administer an intravenous dose of potassium chloride to a client with hypokalemia. The nurse should monitor for which potential complication?

• A. Hyperkalemia
• B. Hypokalemia
• C. Hypernatremia
• D. Hypercalcemia

Correct answer: A

Rationale: When administering potassium chloride to a client with hypokalemia, the nurse should monitor for hyperkalemia. Potassium chloride supplementation aims to increase potassium levels in individuals with hypokalemia. However, excessive administration can lead to hyperkalemia, which can be a serious and potentially life-threatening complication. Monitoring potassium levels is crucial to prevent this adverse outcome. Hypokalemia (Choice B) is the condition being treated, so it is not a complication of treatment. Hypernatremia (Choice C) refers to high sodium levels and is not directly related to the administration of potassium chloride. Hypercalcemia (Choice D) is an elevated calcium level and is not a common complication associated with potassium chloride administration in hypokalemia.

3. A client has a new prescription for verapamil. Which of the following instructions should the nurse include?

• A. Monitor your heart rate daily.
• B. Take the medication at bedtime.
• C. Avoid consuming grapefruit juice.
• D. Take the medication with food.

Correct answer: A

Rationale: The correct answer is to instruct the client to monitor their heart rate daily when taking verapamil. Verapamil is a calcium channel blocker that can cause bradycardia, making it crucial to monitor the heart rate regularly to detect any changes promptly. Choice B, taking the medication at bedtime, is not specifically related to verapamil administration. Choice C, avoiding grapefruit juice, is more relevant to medications metabolized by CYP3A4 enzymes, not verapamil. Choice D, taking the medication with food, is not a specific instruction for verapamil, as it can be taken with or without food.

4. A client is taking haloperidol. Which of the following findings should the nurse report to the provider?

• A. Weight gain
• B. Dry mouth
• C. Tremors
• D. Tardive dyskinesia

Correct answer: D

Rationale: The correct answer is D: Tardive dyskinesia. Tardive dyskinesia is a serious side effect associated with the long-term use of haloperidol. It is characterized by involuntary movements of the face, tongue, and extremities. Early detection is crucial as tardive dyskinesia may be irreversible and should be reported promptly to the healthcare provider for further evaluation and management. Choices A, B, and C are incorrect because weight gain, dry mouth, and tremors are common side effects of haloperidol but are not as concerning as tardive dyskinesia. While they should still be monitored and managed, tardive dyskinesia requires immediate attention due to its potentially irreversible nature.

5. A client with a history of deep vein thrombosis (DVT) is prescribed warfarin (Coumadin). The nurse should include which instruction in the discharge teaching?

• A. Take the medication at the same time each day
• B. Avoid green leafy vegetables in your diet
• C. Increase your intake of vitamin K-rich foods
• D. Stop the medication if you notice any bruising

Correct answer: A

Rationale: Taking warfarin at the same time each day is crucial to maintain consistent blood levels and ensure the effectiveness of the medication in preventing clot formation. Consistent timing helps in monitoring and adjusting the dosage as needed to keep the international normalized ratio (INR) within the therapeutic range to prevent clotting events or excessive bleeding. Choices B, C, and D are incorrect. Avoiding green leafy vegetables is a misconception; while they are high in vitamin K which antagonizes warfarin, they should not be avoided but consumed in moderation. Increasing vitamin K-rich foods can interfere with warfarin's effectiveness. Stopping the medication due to bruising can be dangerous as it may indicate a clotting problem that the medication is intended to prevent.
