Nursing Elites

1. A client's telemetry monitor indicates the sudden onset of ventricular fibrillation. Which assessment finding should the nurse anticipate?

• A. Bounding erratic pulse.
• B. Regularly irregular pulse.
• C. Thready irregular pulse.
• D. No palpable pulse.

Correct answer: D

Rationale: Ventricular fibrillation is a life-threatening arrhythmia characterized by chaotic, asynchronous contractions of the ventricles, resulting in ineffective cardiac output. This leads to the absence of a palpable pulse. Nurses should be prepared to initiate immediate interventions such as defibrillation to restore normal cardiac rhythm in a client experiencing ventricular fibrillation.

2. The healthcare professional is caring for a client with a chest tube following a thoracotomy. Which assessment finding requires immediate intervention?

• A. Continuous bubbling in the water seal chamber.
• B. Serosanguineous drainage in the collection chamber.
• C. Intermittent bubbling in the suction control chamber.
• D. Chest tube secured to the client's chest wall.

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber indicates an air leak, which requires immediate intervention to prevent complications such as pneumothorax. An air leak can lead to ineffective lung expansion, respiratory distress, and compromised gas exchange. Therefore, prompt action is necessary to maintain the integrity of the closed drainage system and prevent further complications. Choices B, C, and D are incorrect because serosanguineous drainage is an expected finding post-thoracotomy, intermittent bubbling in the suction control chamber is normal, and having the chest tube secured to the client's chest wall is essential for stability and proper functioning.

3. A client with deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to assess the effectiveness of the therapy?

• A. Prothrombin time (PT)
• B. Platelet count
• C. Activated partial thromboplastin time (aPTT)
• D. International normalized ratio (INR)

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the appropriate laboratory test to monitor the effectiveness of heparin therapy. Heparin works by prolonging the clotting time, which is reflected in the aPTT results. Monitoring aPTT helps ensure the patient is within the therapeutic range and not at risk of bleeding or clotting complications. Prothrombin time (PT) (Choice A) primarily measures the extrinsic pathway of coagulation and is used to monitor warfarin therapy, not heparin. Platelet count (Choice B) assesses the number of platelets present in the blood and is not specific to monitoring heparin therapy. International normalized ratio (INR) (Choice D) is used to monitor warfarin therapy, not heparin.

4. In acute pancreatitis, a client experiencing severe abdominal pain should have which enzyme level closely monitored?

• A. Serum amylase.
• B. Serum sodium.
• C. Serum calcium.
• D. Serum potassium.

Correct answer: A

Rationale: In acute pancreatitis, serum amylase levels should be closely monitored. Elevated serum amylase levels are a key diagnostic marker for acute pancreatitis, aiding in the assessment and management of the patient's condition. Monitoring serum sodium, calcium, or potassium levels is not typically associated with acute pancreatitis and would not provide relevant information for this specific condition.

5. Why is morphine administered to a patient with a myocardial infarction (MI)?

• A. To reduce pain.
• B. To decrease anxiety.
• C. To reduce cardiac workload.
• D. To increase respiratory rate.

Correct answer: C

Rationale: Morphine is administered to a patient with a myocardial infarction (MI) primarily to reduce cardiac workload. By reducing preload and afterload, morphine helps improve oxygenation to the heart muscle. This decrease in workload on the heart can alleviate symptoms and reduce strain on the heart muscle during an MI. Choices A and B are incorrect because the primary goal of administering morphine in this context is not pain relief or anxiety reduction. Choice D is incorrect as morphine does not aim to increase respiratory rate but rather to address the cardiac workload.
