Nursing Elites

1. A client is admitted with deep vein thrombosis (DVT) and is receiving heparin therapy. What is the most important laboratory value to monitor during heparin therapy?

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

Correct answer: C

Rationale: The activated partial thromboplastin time (aPTT) is the most important laboratory value to monitor during heparin therapy. It measures the intrinsic pathway of coagulation and is used to assess the effectiveness of heparin as an anticoagulant. Keeping the aPTT within the therapeutic range is crucial to prevent complications such as bleeding or clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, not heparin. Platelet count is important to assess for thrombocytopenia, a potential side effect of heparin, but it is not the primary laboratory value to monitor the effectiveness of heparin therapy.

2. The nurse is caring for a client with a suspected myocardial infarction (MI). Which laboratory test result is most indicative of a recent MI?

• A. Elevated troponin levels
• B. Increased white blood cell count
• C. Increased lactate dehydrogenase (LDH)
• D. Elevated C-reactive protein (CRP)

Correct answer: A

Rationale: Elevated troponin levels are the most specific and sensitive indicator of myocardial infarction. Troponin levels increase within hours of an MI and remain elevated for several days. White blood cell count, lactate dehydrogenase (LDH), and C-reactive protein (CRP) are not specific markers for MI. An increased white blood cell count may indicate inflammation or infection, increased LDH levels can be seen in various conditions like liver disease or muscle injury, and elevated CRP is a general marker of inflammation rather than specific to MI.

3. The nurse is preparing an older adult for discharge following cataract extraction. What is the most important instruction?

• A. Avoid straining, bending, or lifting heavy objects.
• B. Limit exposure to sunlight for the first 2 weeks.
• C. Use direct lighting when reading for 6 weeks.
• D. Irrigate the conjunctiva with saline before applying ointment.

Correct answer: A

Rationale: The most important instruction for a patient following cataract extraction is to avoid straining, bending, or lifting heavy objects. These activities can increase intraocular pressure and potentially lead to complications such as bleeding or dislocation of the intraocular lens. Choices B, C, and D are not as critical in the immediate post-operative period. Limiting sunlight exposure and using direct lighting when reading are important but not as crucial as avoiding activities that can increase intraocular pressure. Irrigating the conjunctiva with saline before applying ointment is not a standard post-cataract surgery instruction.

4. A client with type 1 diabetes is admitted to the emergency room with abdominal pain, polyuria, and confusion. What should the nurse implement first?

• A. Administer intravenous insulin.
• B. Start an intravenous fluid bolus.
• C. Obtain a blood glucose level.
• D. Administer an antiemetic.

Correct answer: B

Rationale: In this scenario, the nurse should first start an intravenous fluid bolus. This intervention is crucial in addressing severe dehydration associated with diabetic ketoacidosis, a life-threatening complication of type 1 diabetes. Administering intravenous insulin (Choice A) is important but should follow fluid resuscitation. Obtaining a blood glucose level (Choice C) is necessary but not as urgent as addressing the dehydration. Administering an antiemetic (Choice D) is not the priority in this situation.

5. A client with hyperthyroidism is experiencing palpitations. What intervention should the nurse implement?

• A. Encourage the client to rest and limit activity.
• B. Administer a beta-blocker to reduce heart rate.
• C. Encourage the client to drink cool fluids.
• D. Provide the client with a cool environment.

Correct answer: B

Rationale: In clients with hyperthyroidism experiencing palpitations, administering a beta-blocker is the appropriate intervention. Beta-blockers help reduce heart rate and control symptoms in hyperthyroidism. Encouraging rest (Choice A) may be helpful but does not directly address the palpitations. Drinking cool fluids (Choice C) and providing a cool environment (Choice D) are more focused on temperature regulation and comfort, which are not the primary interventions for palpitations in hyperthyroidism.
