Nursing Elites

1. A client with a history of deep vein thrombosis (DVT) is prescribed warfarin. Which laboratory value should the nurse monitor to assess the therapeutic effect of this medication?

• A. Platelet count
• B. Prothrombin time (PT)
• C. White blood cell count
• D. Hemoglobin level

Correct answer: B

Rationale: Prothrombin time (PT) is the correct laboratory value to monitor to assess the therapeutic effect of warfarin. Warfarin works by inhibiting clotting factors, and PT measures the time it takes for blood to clot. Monitoring PT helps ensure that the medication is working effectively to prevent clot formation without causing excessive bleeding. Platelet count (Choice A) is not specific to warfarin therapy and assesses the number of platelets in the blood. White blood cell count (Choice C) and hemoglobin level (Choice D) are not directly related to monitoring the therapeutic effect of warfarin.

2. A client presents to the emergency department with a severe exacerbation of asthma. The nurse notes that the client is using accessory muscles to breathe and has an oxygen saturation of 86%. Which intervention should the nurse implement first?

• A. Place the client in a high-Fowler's position
• B. Obtain a peak flow reading
• C. Administer a bronchodilator
• D. Administer oxygen therapy

Correct answer: D

Rationale: The first priority in an acute asthma exacerbation is to administer oxygen to improve the client's oxygen saturation. In this scenario, the client has a low oxygen saturation level of 86%, indicating hypoxemia, which can be life-threatening. Administering oxygen therapy will help improve oxygenation and support vital organ function. Once the oxygen levels are stabilized, further interventions such as bronchodilators can be implemented. Placing the client in a high-Fowler's position may also be beneficial, but ensuring adequate oxygenation takes precedence in this critical situation. Obtaining a peak flow reading is important for asthma management but is not the first intervention needed in a client with severe hypoxemia.

3. A client with multiple sclerosis is admitted with an acute exacerbation. What is the nurse's priority action?

• A. Monitor the client’s vital signs every hour.
• B. Assess for changes in the client’s muscle strength.
• C. Administer prescribed corticosteroids to reduce inflammation.
• D. Educate the client on managing fatigue and preventing relapses.

Correct answer: C

Rationale: The correct answer is C. Administering prescribed corticosteroids to reduce inflammation is the priority action when a client with multiple sclerosis is admitted with an acute exacerbation. Corticosteroids help manage symptoms during exacerbations and reduce inflammation. Monitoring vital signs and assessing muscle strength are important aspects of care but not the priority during an acute exacerbation. Educating the client on managing fatigue and preventing relapses is essential but can be addressed after the acute exacerbation has been managed.

4. A teenager presents to the emergency department with palpitations after vaping at a party. The client is anxious, fearful, and hyperventilating. Which acid-base imbalance does the nurse anticipate the client developing?

• A. Metabolic alkalosis
• B. Respiratory alkalosis
• C. Respiratory acidosis
• D. Metabolic acidosis

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation from anxiety or fear causes an excessive loss of CO2, leading to respiratory alkalosis. This shift in pH results from the rapid, shallow breathing that reduces the level of carbon dioxide in the blood. Respiratory acidosis would occur in cases of poor ventilation or CO2 retention, while metabolic acidosis/alkalosis relates to disturbances in bicarbonate, not breathing patterns. Therefore, in this case, the client's hyperventilation due to anxiety would likely result in respiratory alkalosis, making option B the correct choice.

5. A client with lung cancer is admitted to palliative care. What is the nurse's priority assessment?

• A. Monitor respiratory status and oxygenation.
• B. Evaluate the client's mental status and cognition.
• C. Check the client’s pain level and provide comfort.
• D. Assess the client’s nutritional status and appetite.

Correct answer: A

Rationale: Correct Answer: Monitoring respiratory status and oxygenation is crucial in clients with lung cancer, as metastasis to the lungs or pleural effusion can compromise breathing. This assessment helps in early identification of respiratory distress and the need for interventions to maintain adequate oxygenation. Choice B is important but not the priority in this situation. Evaluating mental status and cognition should follow after ensuring the client's physiological needs are met. Choice C, checking pain level and providing comfort, is essential but secondary to assessing respiratory status. Choice D, assessing nutritional status and appetite, is also important but not the priority when the client's breathing is at risk.
