Nursing Elites

1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin) therapy. Which laboratory result indicates that the therapy is effective?

• A. International normalized ratio (INR) of 1.0.
• B. Prothrombin time (PT) of 12 seconds.
• C. Partial thromboplastin time (PTT) of 60 seconds.
• D. International normalized ratio (INR) of 2.5.

Correct answer: D

Rationale: An International Normalized Ratio (INR) of 2.5 indicates that warfarin therapy is within the therapeutic range for a client with atrial fibrillation. A lower INR (such as 1.0) would suggest subtherapeutic levels, risking blood clots. Prothrombin time (PT) and partial thromboplastin time (PTT) are not specific to monitoring warfarin therapy.

2. The healthcare provider is preparing to administer an intravenous antibiotic to a client with a central venous catheter. Which action is most important?

• A. Flush the catheter with heparin.
• B. Change the dressing at the insertion site.
• C. Check for blood return before administering the antibiotic.
• D. Use sterile technique when accessing the catheter.

Correct answer: D

Rationale: Using sterile technique when accessing the catheter is crucial to prevent infection in clients with a central venous catheter. This action helps maintain asepsis and reduces the risk of introducing pathogens into the catheter system. Flushing the catheter with heparin helps prevent occlusion but is not as crucial as ensuring sterile technique. Changing the dressing at the insertion site is important for assessing the site's condition but does not directly impact the administration of the antibiotic. Checking for blood return is essential to ensure proper catheter function, but sterile technique takes precedence to prevent infections.

3. A client with a history of asthma is admitted with shortness of breath. Which finding requires immediate intervention?

• A. Increased respiratory rate.
• B. Absence of breath sounds.
• C. Expiratory wheezes.
• D. Productive cough with green sputum.

Correct answer: B

Rationale: The correct answer is B: Absence of breath sounds. This finding can indicate a pneumothorax or severe asthma exacerbation, both of which require immediate intervention to ensure adequate ventilation and prevent further complications. Increased respiratory rate (choice A) is common in asthma exacerbations but may not always necessitate immediate intervention. Expiratory wheezes (choice C) are typical in asthma and may not always indicate a critical condition. A productive cough with green sputum (choice D) suggests a possible respiratory infection but does not warrant immediate intervention as much as the absence of breath sounds.

4. The healthcare provider is caring for a client with hyperparathyroidism. Which laboratory result requires immediate intervention?

• A. Serum calcium of 11 mg/dL.
• B. Serum phosphorus of 3 mg/dL.
• C. Serum magnesium of 1.8 mg/dL.
• D. Serum albumin of 4 g/dL.

Correct answer: A

Rationale: A serum calcium level of 11 mg/dL indicates hypercalcemia, which can be a complication of hyperparathyroidism and requires immediate intervention. Hypercalcemia can lead to serious complications such as cardiac dysrhythmias, renal failure, and neurologic symptoms. Monitoring and managing serum calcium levels are crucial in clients with hyperparathyroidism. Serum phosphorus, magnesium, and albumin levels are important to assess in clients with hyperparathyroidism, but they do not require immediate intervention as hypercalcemia poses a more urgent risk.

5. The client is receiving warfarin (Coumadin) therapy. Which statement by the client indicates a need for further teaching?

• A. I will avoid eating foods high in vitamin K.
• B. I will use a soft toothbrush and an electric razor.
• C. I will keep all appointments for blood tests.
• D. I will avoid participating in contact sports.

Correct answer: D

Rationale: The correct answer is D because participating in contact sports can increase the risk of injury and bleeding in a client receiving warfarin therapy. Warfarin is a blood thinner, and activities with a higher risk of injury should be avoided to prevent bleeding complications. Choices A, B, and C are all correct statements for a client on warfarin therapy. Avoiding foods high in vitamin K helps maintain consistent anticoagulation levels, using a soft toothbrush and an electric razor reduces the risk of bleeding gums and cuts, and keeping appointments for blood tests ensures proper monitoring of the client's international normalized ratio (INR) levels.
