1. A patient with a diagnosis of deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the heparin therapy?
- A. Prothrombin time (PT)
- B. Partial thromboplastin time (PTT)
- C. Bleeding time
- D. Platelet count
Correct answer: B
Rationale: The correct answer is B: Partial thromboplastin time (PTT). Heparin affects the intrinsic pathway of the coagulation cascade, which is reflected by changes in the PTT. Monitoring the PTT helps ensure that the patient's blood is within the desired therapeutic range and prevents complications related to clotting or bleeding. Prothrombin time (PT) primarily assesses the extrinsic pathway and is not as sensitive to heparin therapy. Bleeding time and platelet count are not specific tests for monitoring the effectiveness of heparin therapy in DVT.
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 55-year-old woman presents with fatigue, pruritus, and jaundice. Laboratory tests reveal elevated bilirubin and alkaline phosphatase levels. Imaging shows dilated intrahepatic bile ducts and a normal common bile duct. What is the most likely diagnosis?
- A. Primary biliary cirrhosis
- B. Primary sclerosing cholangitis
- C. Gallstones
- D. Pancreatic cancer
Correct answer: A
Rationale: The presentation of fatigue, pruritus, and jaundice in a 55-year-old woman, along with elevated bilirubin and alkaline phosphatase levels, and imaging findings of dilated intrahepatic bile ducts and a normal common bile duct, are characteristic of primary biliary cirrhosis. Primary biliary cirrhosis is an autoimmune liver disease that typically affects middle-aged women, leading to progressive destruction of the intrahepatic bile ducts.
4. The healthcare provider is caring for a patient who is taking warfarin (Coumadin). Which laboratory value should the healthcare provider monitor closely?
- A. Platelet count.
- B. Prothrombin time (PT).
- C. Hemoglobin level.
- D. White blood cell count.
Correct answer: B
Rationale: Corrected Rationale: When caring for a patient on warfarin, monitoring prothrombin time (PT) is crucial. PT helps assess the blood's ability to clot properly, ensuring the patient maintains therapeutic anticoagulation levels while minimizing bleeding risks. Platelet count (Choice A) is important but not the most critical for warfarin therapy. Hemoglobin level (Choice C) and white blood cell count (Choice D) are not directly related to monitoring the effects of warfarin.
5. When evaluating a client's understanding of wearing a Holter monitor, which statement made by the client would indicate to the nurse that the client understands the procedure?
- A. I must record any symptoms occurring with my activity.
- B. I am not looking forward to staying in bed for 24 hours.
- C. I really am dreading the frequent blood drawing.
- D. I know that I shouldn't get close to my microwave oven.
Correct answer: A
Rationale: The correct answer is A. Recording symptoms that occur with activity is crucial when wearing a Holter monitor. This information helps in correlating symptoms with cardiac events, aiding in the diagnosis and treatment of the client's condition. The client's understanding of this aspect demonstrates comprehension of the procedure and its purpose.
