ATI Fluid Electrolyte and Acid-Base Regulation Questions
Question 1 of 5
A nurse assesses a client who has a radial artery catheter. Which assessment should the nurse complete first?
Correct Answer: D
Rationale: The correct answer is D: Presence of an ulnar pulse. This is the most important assessment to complete first because the presence of an ulnar pulse indicates adequate circulation in the hand, ensuring that the radial artery catheter is not compromising blood flow. If the ulnar pulse is absent, it may signify impaired circulation and potential complications such as ischemia. Choice A is incorrect because the amount of pressure in the fluid container is not directly related to the assessment of the radial artery catheter. Choice B is incorrect because the date of catheter tubing change is important for infection control but not the immediate priority in this situation. Choice C is incorrect as the percent of heparin in the infusion container is important for anticoagulation therapy but does not take precedence over assessing circulation in the hand.
Question 2 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 3 of 5
A nurse is caring for a client who is receiving an epidural infusion for pain management. Which assessment finding requires immediate intervention from the nurse?
Correct Answer: B
Rationale: The correct answer is B: Report of headache and stiff neck. This finding indicates a potential complication of epidural anesthesia called a post-dural puncture headache, which can lead to serious consequences like meningitis or subdural hematoma. The nurse should act immediately by notifying the healthcare provider for further evaluation and management. Redness at the catheter insertion site (A) may indicate local inflammation but doesn't require immediate intervention. Temperature elevation (C) could be a sign of infection but isn't as urgent as a headache and stiff neck. Pain rating of 8 (D) is important but doesn't indicate an immediate threat to the client's health like a post-dural puncture headache.
Question 4 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 5 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.
