Question 1 of 5
A nurse is caring for a client who is having a subclavian central venous catheter inserted. The client begins to report chest pain and difficulty breathing. After administering oxygen, which action should the nurse take next?
Correct Answer: B
Rationale: The correct answer is B: Prepare to assist with chest tube insertion. Chest pain and difficulty breathing after subclavian central venous catheter insertion could indicate a pneumothorax, a potential complication. Chest tube insertion is indicated to help re-expand the lung and relieve the pressure in the thoracic cavity. This intervention takes priority over the other options because it addresses the potential life-threatening complication of a pneumothorax. Administering nitroglycerin (choice A) is not indicated for chest pain in this scenario. Placing a sterile dressing over the IV site (choice C) is not appropriate for managing chest pain and difficulty breathing. Re-positioning the client into the Trendelenburg position (choice D) is not effective in addressing a pneumothorax and may worsen the client's condition.
Question 2 of 5
. A nurse assesses a client who had an intraosseous catheter placed in the left leg. Which assessment finding is of greatest concern?
Correct Answer: D
Rationale: The correct answer is D. A cool lower extremity can indicate impaired circulation due to the intraosseous catheter placement, leading to compartment syndrome or tissue necrosis. This finding requires immediate intervention to prevent serious complications. Choices A, B, and C are incorrect because the duration of catheter placement, poor vascular access, and the specific location of the catheter do not directly impact circulation and tissue perfusion as significantly as a cool lower extremity.
Question 3 of 5
A nurse is assessing clients who have intravenous therapy prescribed. Which assessment finding for a client with a peripherally inserted central catheter (PICC) requires immediate attention?
Correct Answer: D
Rationale: The correct answer is D because upper extremity swelling could indicate a potential complication such as deep vein thrombosis, which is a serious condition requiring immediate attention to prevent further complications. Swelling can impede blood flow and lead to clot formation. A: The initial site dressing being 3 days old is concerning for infection but not an immediate threat. B: The PICC being inserted 4 weeks ago may increase infection risk but does not require immediate attention. C: A missing securement device may increase the risk of dislodgement but is not an immediate threat compared to potential vascular compromise indicated by upper extremity swelling.
Question 4 of 5
.A nurse assesses a clients peripheral IV site, and notices edema and tenderness above the site. Which action should the nurse take next?
Correct Answer: D
Rationale: The correct action is to stop the infusion of intravenous fluids. Edema and tenderness above the IV site suggest infiltration, where fluid leaks into surrounding tissues. Stopping the infusion prevents further damage and helps prevent complications. Applying cold compresses (A) may not address the underlying issue. Elevating the extremity (B) is helpful for other conditions like swelling due to dependent edema, not infiltration. Flushing the catheter (C) can exacerbate the issue by pushing more fluid into the tissue.
Question 5 of 5
While assessing a clients peripheral IV site, the nurse observes a streak of red along the vein path and palpates a 4-cm venous cord. How should the nurse document this finding?
Correct Answer: A
Rationale: The correct answer is A: Grade 3 phlebitis at IV site. This finding indicates inflammation of the vein due to irritants from the IV catheter, supported by red streak and palpable cord. Grade 3 phlebitis involves pain, redness, swelling, and palpable venous cord. Infection (B) typically presents with signs like pus, warmth, and fever. Thrombosis (C) involves a blood clot, not a palpable cord. Infiltration (D) is leakage of IV fluid into surrounding tissues, not related to palpable cord and red streak.
