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. The nurse is preparing to administer a subcutaneous injection to a thin, elderly client. What is the most appropriate site for the injection?

• A. Dorsal aspect of the upper arm.
• B. Upper outer thigh.
• C. Lower abdomen.
• D. Lateral aspect of the upper arm.

Correct answer: B

Rationale: The correct answer is the upper outer thigh. In thin, elderly clients, the upper outer thigh is a recommended site for subcutaneous injections due to the presence of adequate subcutaneous tissue and muscle mass. The dorsal aspect of the upper arm may not provide enough subcutaneous tissue for proper absorption of the medication. The lower abdomen is not ideal for thin individuals as it may lead to injection into muscle rather than subcutaneous tissue. The lateral aspect of the upper arm is also not a commonly recommended site for subcutaneous injections.

3. During an acute exacerbation of asthma, what is the nurse's first action for a client experiencing this condition?

• A. Administer a bronchodilator as prescribed.
• B. Check the client's oxygen saturation.
• C. Reassure the client and encourage deep breathing.
• D. Provide emotional support to reduce anxiety.

Correct answer: A

Rationale: The correct first action when managing an acute exacerbation of asthma is to administer a bronchodilator as prescribed. Bronchodilators help open the airways and improve breathing in individuals experiencing an asthma exacerbation. Checking oxygen saturation (Choice B) is important but not the first action. Reassuring the client and encouraging deep breathing (Choice C) can be beneficial but should come after administering the bronchodilator. Providing emotional support to reduce anxiety (Choice D) is important but is not the initial priority in managing an acute exacerbation of asthma.

4. A client with Crohn's disease reports diarrhea. What intervention should the nurse implement?

• A. Instruct the client to drink clear fluids and avoid solid foods.
• B. Administer antidiarrheal medication as prescribed.
• C. Encourage a high-fiber diet and regular physical activity.
• D. Restrict fluid intake and monitor electrolytes.

Correct answer: C

Rationale: The correct intervention for a client with Crohn's disease reporting diarrhea is to encourage a high-fiber diet and regular physical activity. A high-fiber diet helps manage diarrhea in Crohn's disease by adding bulk to the stool and promoting more regular bowel movements. Instructing the client to drink clear fluids and avoid solid foods (Choice A) may not be appropriate as it can further exacerbate diarrhea. Administering antidiarrheal medication (Choice B) without addressing the underlying cause may not be the best initial approach. Encouraging a high-fiber diet and physical activity (Choice C) is beneficial for managing symptoms. Restricting fluid intake and monitoring electrolytes (Choice D) is not recommended as it can lead to dehydration, which is a concern in clients with diarrhea.

5. Prolonged exposure to high concentrations of supplemental oxygen over several days can cause which pathophysiological effect?

• A. Reduced cardiac output
• B. Disrupted surfactant production
• C. Hyperactivity of alveoli
• D. Increased oxygen carrying capacity

Correct answer: B

Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.
