The nurse is caring for a client with a chest tube in place following a pneumothorax. Which finding requires immediate intervention?

A. Oxygen saturation of 95%

B. Crepitus around the insertion site

C. Subcutaneous emphysema

D. Drainage of 50 ml per hour

Correct Answer: C
Rationale: Subcutaneous emphysema requires immediate intervention in a client with a chest tube following a pneumothorax as it can indicate a pneumothorax recurrence or air leak. Oxygen saturation of 95% is within the normal range and does not require immediate intervention. Crepitus around the insertion site can be expected post-procedure and may not necessitate immediate action. Drainage of 50 ml per hour is a normal finding and does not raise immediate concerns.

A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which assessment finding is most concerning?

• A. Bradycardia
• B. Muscle weakness
• C. Peaked T waves on the ECG
• D. Decreased deep tendon reflexes

Correct Answer: C
Rationale: The correct answer is C: Peaked T waves on the ECG. In hyperkalemia, elevated potassium levels can affect the heart's electrical activity, leading to changes on the ECG such as peaked T waves. This finding is concerning as it can progress to serious cardiac arrhythmias, including ventricular tachycardia and fibrillation. Bradycardia (choice A) and decreased deep tendon reflexes (choice D) are not typically associated with hyperkalemia. While muscle weakness (choice B) can occur in hyperkalemia due to its effect on neuromuscular function, the most concerning assessment finding indicating the need for immediate intervention in this scenario is peaked T waves on the ECG.

A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which clinical finding is most concerning?

• A. Headache
• B. Prothrombin time (PT) of 15 seconds
• C. Elevated liver enzymes
• D. Peripheral edema

Correct Answer: A
Rationale: The correct answer is A: Headache. In a client with atrial fibrillation taking warfarin (Coumadin), a headache can be indicative of bleeding, which is a serious complication requiring immediate assessment and intervention. Monitoring for signs of bleeding is crucial when on anticoagulant therapy. Choices B, C, and D are not the most concerning. A prothrombin time of 15 seconds is within the therapeutic range for a client on warfarin, elevated liver enzymes may indicate liver dysfunction but are not directly related to the medication's side effects, and peripheral edema is not typically associated with warfarin use or atrial fibrillation in this context.

A school nurse is called to the soccer field because a child has a nosebleed (epistaxis). In what position should the nurse place the child?

• A. Sitting up and leaning forward
• B. Lying flat with legs elevated
• C. Lying on the side with the head slightly raised
• D. Sitting up and tilting the head back

Correct Answer: A
Rationale: The child with a nosebleed (epistaxis) should be placed in a sitting position, leaning forward, to prevent blood from flowing down the throat. This position helps to control the bleeding and prevents the child from swallowing blood, which can cause nausea or vomiting. Choice B is incorrect because elevating the legs is not recommended for nosebleeds. Choice C is incorrect because lying on the side with the head slightly raised is not the optimal position for managing a nosebleed. Choice D is incorrect because tilting the head back can lead to blood flowing down the throat and potentially cause aspiration.

A male client with rheumatoid arthritis is scheduled for a procedure in the morning. The procedure cannot be completed due to early morning stiffness. Which intervention should the nurse implement?

• A. Assign a UAP to assist the client with a warm shower early in the morning.
• B. Administer anti-inflammatory medication before the procedure.
• C. Encourage the client to perform range-of-motion exercises.
• D. Reschedule the procedure for later in the day.

Correct Answer: A
Rationale: A warm shower can help alleviate stiffness, allowing the client to be more comfortable and mobile before the procedure. This intervention promotes increased comfort and mobility, which may help the client proceed with the procedure later in the day. Administering anti-inflammatory medication (Choice B) may be helpful but may take time to be effective, while range-of-motion exercises (Choice C) may be challenging for the client due to stiffness. Rescheduling the procedure (Choice D) does not address the immediate need to alleviate stiffness.
