A client with a history of myocardial infarction (MI) is admitted with chest pain. Which laboratory test should the nurse expect to be ordered to determine if the client is experiencing another MI?
- A. Troponin
- B. Myoglobin
- C. CK-MB
- D. C-reactive protein
Correct Answer: A
Rationale: Troponin is the most specific and sensitive laboratory test for detecting myocardial infarction (MI). It is released when there is damage to the heart muscle, making it a valuable marker for diagnosing another MI. Myoglobin and CK-MB can also be elevated in MI, but troponin is preferred due to its higher specificity. C-reactive protein is a marker of inflammation and not specific to MI.

What intervention should the healthcare provider include in the plan of care for a client receiving treatment with an Unna's paste boot for leg ulcers due to chronic venous insufficiency?
- A. Check capillary refill of toes on the lower extremity with the Unna's paste boot.
- B. Apply dressing to the wound area before applying the Unna's paste boot.
- C. Wrap the leg from the knee down towards the foot.
- D. Remove the Unna's paste boot every 8 hours to assess wound healing.
Correct Answer: A
Rationale: When an Unna's paste boot is applied for leg ulcers due to chronic venous insufficiency, it is crucial to check the capillary refill of the toes on the lower extremity to ensure adequate circulation. The Unna's paste boot can become rigid after drying, potentially affecting circulation distally. Monitoring capillary refill helps assess the perfusion status of the distal extremity and ensures that the treatment is not compromising circulation to the toes.
A client is 2 days post-op from thoracic surgery and is complaining of incisional pain. The client last received pain medication 2 hours ago. He is rating his pain as a 5 on a 1-10 scale. After calling the provider, what is the nurse's next action?
- A. Instruct the client to use guided imagery and slow rhythmic breathing
- B. Provide at least 20 minutes of back massage and gentle effleurage
- C. Encourage the client to watch TV
- D. Place a hot water circulation device, such as an Aqua K pad, to the operative site
Correct Answer: A
Rationale: In this scenario, since no additional pain medication is available, the nurse should recommend non-pharmacological pain management techniques. Guided imagery and slow rhythmic breathing can help the client manage incisional pain effectively. These techniques can provide distraction and relaxation, potentially reducing the perception of pain without the need for additional medication.
When measuring vital signs, the healthcare provider observes that a client is using accessory neck muscles during respirations. What follow-up action should the healthcare provider take first?
- A. Determine pulse pressure
- B. Auscultate heart sounds
- C. Measure oxygen saturation
- D. Check for neck vein distention
Correct Answer: C
Rationale: Observing a client using accessory neck muscles during respiration indicates respiratory distress. The priority action should be to measure oxygen saturation to assess the adequacy of oxygenation. This intervention provides crucial information about the client's respiratory status and helps guide further assessment and interventions.
The healthcare provider is providing passive range of motion (ROM) exercises to the hip and knee for a client who is unconscious. After supporting the client's knee with one hand, what action should the healthcare provider take next?
- A. Raise the bed to a comfortable working level.
- B. Bend the client's knee.
- C. Move the knee toward the chest as far as it will go.
- D. Cradle the client's heel.
Correct Answer: D
Rationale: When providing passive ROM exercises to the hip and knee for an unconscious client, it is essential to support the joints of the knee and ankle. The next action should be to cradle the client's heel and gently move the limb in a slow, smooth, firm, but gentle manner. This helps maintain joint mobility and prevent contractures.
A client is receiving intravenous (IV) fluids postoperatively. Which assessment finding should prompt the nurse to stop the infusion and notify the healthcare provider?
- A. The client reports pain at the IV site
- B. The client's blood pressure is elevated
- C. The client has swelling at the IV site
- D. The client's heart rate is irregular
Correct Answer: C
Rationale: Swelling at the IV site may indicate infiltration or phlebitis, which requires stopping the IV infusion and notifying the healthcare provider. Infiltration occurs when the IV fluid leaks into the surrounding tissue, causing swelling and potential damage. It is crucial to act promptly to prevent further complications and ensure the client's safety.
