Nursing Elites

1. 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.

2. 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.

3. Following discharge teaching, a male client with a duodenal ulcer tells the nurse that he will drink plenty of dairy products, such as milk, to help coat and protect his ulcer. What is the best follow-up action by the nurse?

• A. Encourage the client to drink milk
• B. Review with the client the need to avoid foods that are rich in milk and cream
• C. Instruct the client to take antacids instead
• D. Advise the client to monitor their symptoms

Correct answer: B

Rationale: The client should be advised to avoid foods rich in milk and cream. Although they provide temporary relief, dairy products, especially milk, stimulate gastric acid secretion, which can exacerbate the symptoms of a duodenal ulcer. Encouraging the client to drink milk (Choice A) would be counterproductive and could worsen the condition. Instructing the client to take antacids (Choice C) may provide symptomatic relief but does not address the root cause of the issue. Advising the client to monitor their symptoms (Choice D) is vague and does not provide specific guidance on managing the duodenal ulcer. Therefore, the best action is to review with the client the need to avoid foods rich in milk and cream to ensure proper ulcer management.

4. The nurse is caring for a client with a chest tube following surgery. The nurse should intervene if which of the following is observed?

• A. The chest tube is securely taped at the insertion site.
• B. The water seal chamber is filled to the correct level.
• C. The chest drainage system is below chest level.
• D. There are no air leaks in the system.

Correct answer: C

Rationale: The correct answer is C. The chest drainage system should always be kept below chest level to ensure proper drainage. Having the system above chest level can result in ineffective drainage. Choices A, B, and D are all correct actions to maintain the integrity and functionality of the chest tube system. Securing the chest tube at the insertion site, maintaining the water seal chamber at the correct level, and ensuring there are no air leaks are all essential components of caring for a client with a chest tube post-surgery.

5. A client receiving total parenteral nutrition (TPN) is experiencing nausea and vomiting. What is the nurse's first action?

• A. Check the client's blood glucose level.
• B. Decrease the rate of TPN infusion.
• C. Administer an antiemetic as prescribed.
• D. Check the client's TPN bag for solution accuracy.

Correct answer: D

Rationale: The correct first action for the nurse to take when a client receiving TPN is experiencing nausea and vomiting is to check the client's TPN bag for solution accuracy. This is crucial to ensure that the correct solution is being administered and to address any potential errors. Checking the blood glucose level or administering an antiemetic may be necessary interventions but addressing the TPN bag's accuracy should be the priority to prevent any complications related to incorrect TPN solution.
