Nursing Elites

1. Which of the following lab values indicates a patient on warfarin is at a therapeutic level?

• A. INR of 1.1
• B. PT of 12 seconds
• C. INR of 2.5
• D. Platelet count of 150,000

Correct answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

2. A nurse is reviewing the medical records of a client with chronic heart failure. What dietary recommendation should the nurse make?

• A. Follow a 3g sodium diet.
• B. Drink at least 3 liters of fluid per day.
• C. Place the client's lower extremities on two pillows.
• D. Maintain the client's oxygen saturation at 89%.

Correct answer: A

Rationale: The correct answer is A: Follow a 3g sodium diet. For clients with chronic heart failure, limiting sodium intake is crucial to prevent fluid retention and exacerbation of heart failure symptoms. High sodium intake can lead to fluid buildup, causing the heart to work harder. Choices B, C, and D are incorrect. Drinking excessive fluid can worsen fluid retention in heart failure, elevating the workload of the heart. Placing the client's lower extremities on two pillows is a positioning intervention to alleviate edema, not a dietary recommendation. Maintaining oxygen saturation at 89% is more related to respiratory status rather than dietary management of chronic heart failure.

3. A nurse is assessing a client with a history of post-traumatic stress disorder (PTSD). Which of the following findings should the nurse expect?

• A. Dependence on family and friends
• B. Loss of interest in usual activities
• C. Ritualistic behavior
• D. Passive-aggressive behavior

Correct answer: B

Rationale: The correct answer is B: Loss of interest in usual activities. Clients with PTSD often exhibit symptoms such as numbing, which can manifest as a loss of interest in activities they once enjoyed. Choice A, dependence on family and friends, is more indicative of seeking support rather than a direct symptom of PTSD. Choice C, ritualistic behavior, is more commonly associated with conditions like obsessive-compulsive disorder. Choice D, passive-aggressive behavior, is not a typical finding in clients with PTSD.

4. What is the most appropriate intervention for a patient with confusion post-surgery?

• A. Administer oxygen
• B. Reposition the patient
• C. Administer IV fluids
• D. Perform a neurological assessment

Correct answer: A

Rationale: Administering oxygen is the most appropriate intervention for a patient with confusion post-surgery because it helps alleviate confusion caused by potential hypoxia. In a post-surgical setting, confusion can be a sign of decreased oxygen levels in the blood due to various reasons such as respiratory depression, decreased lung function, or other complications. Administering oxygen can quickly address hypoxia, improving oxygenation to the brain and reducing confusion. Repositioning the patient, administering IV fluids, or performing a neurological assessment are not the primary interventions for confusion related to hypoxia post-surgery.

5. Which lab value is most critical to monitor in a patient receiving digoxin?

• A. Monitor potassium levels
• B. Monitor sodium levels
• C. Monitor calcium levels
• D. Monitor magnesium levels

Correct answer: A

Rationale: The correct answer is to monitor potassium levels in a patient receiving digoxin. Hypokalemia can potentiate the toxic effects of digoxin, leading to serious cardiac arrhythmias. Monitoring potassium levels helps prevent toxicity. Monitoring sodium levels (Choice B), calcium levels (Choice C), and magnesium levels (Choice D) are also important aspects of patient care, but potassium levels are most critical in patients on digoxin therapy.
