Nursing Elites

1. The nurse is caring for a client who is receiving a continuous intravenous infusion of heparin. Which laboratory value should the nurse monitor to evaluate the effectiveness of the therapy?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Partial thromboplastin time (PTT)
• D. Hemoglobin level

Correct answer: C

Rationale: The correct answer is C. Partial thromboplastin time (PTT) is the laboratory value that should be monitored to evaluate the effectiveness of heparin therapy. PTT reflects the intrinsic pathway of coagulation and is specifically sensitive to heparin's anticoagulant effects. Monitoring the PTT helps ensure that the client is within the therapeutic range to prevent clot formation without increasing the risk of bleeding. Choices A, B, and D are incorrect because while they are important laboratory values in other contexts, they are not specifically used to monitor the effectiveness of heparin therapy.

2. A client diagnosed with a deep vein thrombus (DVT) followed by a diagnosis of pulmonary embolism (PE) is receiving heparin via an infusion pump at a rate of 1400 u/hour. The client tells the nurse, 'I wish this medicine would hurry up and dissolve this clot in my lung so that I can go home'. What response is best for the nurse to provide?

• A. Heparin prevents future clot formation, but your risk of bleeding needs to be monitored closely
• B. You seem to be concerned about the length of time it takes for Heparin to dissolve this clot
• C. Let me contact your surgeon and find out if Heparin IV therapy can be administered to you at home
• D. Why are you so anxious to leave the hospital when you know you are not well enough yet?

Correct answer: A

Rationale: Choice A is the best response because it educates the client about the role of heparin in preventing future clot formation rather than dissolving the existing clot. This helps the client understand the medication's function and the importance of closely monitoring for signs of bleeding, a common side effect of heparin therapy. Choice B acknowledges the client's concern but does not provide accurate information about heparin's mechanism of action. Choice C is premature as it suggests transitioning to home therapy without addressing the client's concerns or explaining heparin's purpose. Choice D does not address the client's statement and instead questions their desire to leave the hospital.

3. Which instruction should the nurse provide to an elderly client who is taking an ACE inhibitor and a calcium channel blocker?

• A. Wear long-sleeved clothing when outdoors
• B. Report the onset of sore throat
• C. Eat plenty of potassium-rich food
• D. Change the position slowly

Correct answer: D

Rationale: The correct instruction for an elderly client taking both an ACE inhibitor and a calcium channel blocker is to change positions slowly. Both medications can lead to orthostatic hypotension, a sudden drop in blood pressure when changing positions, which can increase the risk of falls. Instructing the client to change positions slowly helps prevent falls. Wearing long-sleeved clothing when outdoors does not directly relate to the medication combination. Reporting the onset of a sore throat is important for monitoring potential side effects but is not specific to these medications. While potassium levels should be monitored with ACE inhibitors, eating plenty of potassium-rich foods without guidance can lead to hyperkalemia, a potential side effect of ACE inhibitors.

4. The nurse working in an emergency center collects physical evidence 6 hours following a reported sexual assault. After placing the samples in sealed containers, which action is most important for the nurse to implement?

• A. Maintain possession of the evidence collection kit at all times until submitted to law enforcement
• B. Provide discharge instructions for prophylactic antibiotics, pregnancy, and HIV prevention medication
• C. Document the characteristics of the various sites of sample collection
• D. Assist the client with toileting, hygiene, and dressing with clean clothes

Correct answer: A

Rationale: Maintaining possession of the evidence collection kit at all times until submitted to law enforcement is crucial to ensure the integrity of the chain of custody. This step helps prevent tampering or contamination of the evidence, which is vital for the legal process. Providing discharge instructions for medications, documenting sample characteristics, and assisting the client with personal care are important aspects of care but not the immediate priority when handling forensic evidence in a sexual assault case.

5. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen at 2 liters per minute by nasal cannula. The client develops respiratory distress and the nurse increases the oxygen to 4 liters per minute. Shortly afterward, the client becomes lethargic and confused. What action should the nurse take first?

• A. Reposition the nasal cannula
• B. Lower the oxygen rate
• C. Encourage the client to cough and deep breathe
• D. Monitor the client's oxygen saturation level

Correct answer: B

Rationale: In this scenario, the client with COPD receiving increased oxygen is experiencing oxygen toxicity, leading to lethargy and confusion. Lowering the oxygen rate is the priority action to prevent further harm. Repositioning the nasal cannula, encouraging coughing and deep breathing, and monitoring oxygen saturation are all important interventions, but the immediate concern is to address the oxygen toxicity by lowering the oxygen rate.
