Nursing Elites

1. A nurse is assessing a client who has a history of atrial fibrillation and is receiving warfarin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the warfarin?

• A. Platelet count
• B. International normalized ratio (INR)
• C. Bleeding time
• D. Partial thromboplastin time (PTT)

Correct answer: B

Rationale: The correct answer is B: International normalized ratio (INR). The INR is used to monitor the effectiveness of warfarin therapy. A higher INR indicates a longer time it takes for the blood to clot, which is desirable in patients receiving warfarin to prevent blood clots. Platelet count (Choice A) assesses the number of platelets in the blood and is not directly related to warfarin therapy. Bleeding time (Choice C) evaluates the time it takes for a person to stop bleeding after a standardized wound, but it is not specific to monitoring warfarin effectiveness. Partial thromboplastin time (PTT) (Choice D) is more commonly used to monitor heparin therapy, not warfarin.

2. A nurse is providing discharge teaching to a client with heart failure and a prescription for furosemide 20 mg PO twice daily. Which of the following instructions should the nurse include in the teaching?

• A. Monitor for increased blood pressure
• B. Increase intake of high-potassium foods
• C. Expect an increase in swelling in the hands and feet
• D. Take the second dose at bedtime

Correct answer: B

Rationale: The correct answer is B: "Increase intake of high-potassium foods." Furosemide is a loop diuretic that can lead to hypokalemia, a condition characterized by low potassium levels. To prevent this adverse effect, the client should increase their intake of high-potassium foods. Choice A is incorrect because furosemide typically leads to decreased blood pressure, not increased. Choice C is incorrect because furosemide is used to reduce swelling, not increase it. Choice D is incorrect because the second dose of furosemide should be taken in the morning to prevent nocturia.

3. A nurse is assessing a client who has a blood glucose level of 250 mg/dL. Which of the following clinical manifestations is associated with this finding?

• A. Confusion
• B. Thirst
• C. Diaphoresis
• D. Shakiness

Correct answer: B

Rationale: Corrected Detailed Rationale: A blood glucose level of 250 mg/dL indicates hyperglycemia. Thirst (polydipsia) is a common clinical manifestation associated with hyperglycemia. The body tries to compensate for the high blood sugar by increasing fluid intake. Confusion (choice A) is more commonly associated with hypoglycemia, not hyperglycemia. Diaphoresis (choice C) and shakiness (choice D) are typical manifestations of hypoglycemia, not hyperglycemia. Therefore, the correct answer is increased thirst (polydipsia) in response to the elevated blood glucose level.

4. A nurse is assessing a client with suspected myocardial infarction. Which finding should the nurse report to the provider?

• A. Pain radiating to the left arm
• B. Pain relieved by rest
• C. Pain worsened with breathing
• D. Pain relieved by antacids

Correct answer: A

Rationale: The correct answer is A: Pain radiating to the left arm. This is a classic symptom of myocardial infarction and indicates possible heart involvement. Reporting this finding to the provider is crucial for prompt evaluation and intervention. Choices B, C, and D are incorrect. Pain relieved by rest, pain worsened with breathing, and pain relieved by antacids are not typical symptoms of myocardial infarction. These findings do not raise the same level of concern as pain radiating to the left arm and are less indicative of cardiac involvement.

5. A client is being educated by a nurse about the use of carbidopa-levodopa. Which of the following should be included?

• A. It will cure Parkinson's disease
• B. Monitor for dyskinesia
• C. It can be taken with food
• D. It is an opioid medication

Correct answer: B

Rationale: The correct answer is to 'Monitor for dyskinesia.' Carbidopa-levodopa can cause dyskinesia as a side effect, characterized by involuntary movements. Monitoring for this side effect is crucial. Choice A is incorrect because carbidopa-levodopa helps manage symptoms of Parkinson's disease but does not cure it. Choice C is incorrect because carbidopa-levodopa should be taken on an empty stomach to enhance absorption. Choice D is incorrect because carbidopa-levodopa is not an opioid medication.
