ATI Fluid Electrolyte and Acid-Base Regulation Questions

Question 1 of 5

. One day after a patient is admitted to the medical unit, you note that the patient is oliguric. You notify the acutecare nurse practitioner who orders a fluid challenge of 200 mL of normal saline solution over 15 minutes. This intervention will achieve which of the following?

Correct Answer: C

Rationale: The correct answer is C: Help distinguish reduced renal blood flow from decreased renal function. Rationale: 1. Oliguria is a decrease in urine output. 2. Fluid challenge with normal saline can help determine the cause of oliguria by assessing the response of the kidneys. 3. If the oliguria improves after the fluid challenge, it suggests reduced renal blood flow as the cause. 4. If oliguria persists, it indicates decreased renal function. Summary: A. Fluid challenge does not directly help in distinguishing between hyponatremia and hypernatremia. B. Evaluating pituitary gland function requires specific tests, not just a fluid challenge. D. Treating hypertension-induced oliguria may involve different interventions, not just a fluid challenge.

Question 2 of 5

The nurse is assessing the patient for the presence of a Chvosteks sign. What electrolyte imbalance would a positive Chvosteks sign indicate?

Correct Answer: C

Rationale: Step 1: Chvostek's sign is a facial muscle spasm induced by tapping the facial nerve in hypocalcemia. Step 2: Hypocalcemia causes increased neuromuscular excitability, leading to Chvostek's sign. Step 3: Hyperkalemia (choice D) causes muscle weakness, not muscle spasm. Step 4: Hyponatremia (choice B) affects osmolarity, not neuromuscular excitability. Step 5: Hypermagnesemia (choice A) causes muscle weakness, not muscle spasm.

Question 3 of 5

A nurse is caring for an older adult client who is admitted with moderate dehydration. Which intervention should the nurse implement to prevent injury while in the hospital?

Correct Answer: D

Rationale: The correct answer is D because dangling the client on the bedside before ambulating helps prevent orthostatic hypotension and potential falls. This step allows the nurse to assess the client's tolerance to changes in position and reduces the risk of injury. A: Asking family members to speak quietly does not directly address the prevention of injury related to dehydration. B: Assessing urine parameters is important for monitoring hydration status but does not directly prevent injury. C: Encouraging fluid intake is important for rehydration but does not directly address the risk of injury during ambulation.

Question 4 of 5

A nurse is caring for a client who has just had a central venous access line inserted. Which action should the nurse take next?

Correct Answer: B

Rationale: The correct answer is B: Ensure an x-ray is completed to confirm placement. This is crucial to prevent complications such as pneumothorax or incorrect placement. X-ray confirmation is the gold standard to verify the central line's proper positioning before initiating any infusions. Option A is incorrect because starting the infusion without confirming placement can lead to serious complications. Option C is unnecessary for central line insertion. Option D is important but not the immediate next step as confirming placement takes precedence for patient safety.

Question 5 of 5

A nurse is caring for a client with a peripheral vascular access device who is experiencing pain, redness, and swelling at the site. After removing the device, which action should the nurse take to relieve pain?

Correct Answer: B

Rationale: The correct answer is B: Place warm compresses on the site. Warm compresses can help increase blood flow, reduce pain, and promote healing at the site of inflammation. The warmth can help dilate blood vessels, increasing circulation to the area and promoting the removal of inflammatory substances. This can help alleviate pain and reduce swelling. Administering topical lidocaine (choice A) may not address the underlying cause of pain and redness. Administering oral pain medication (choice C) may be necessary for severe pain but may not directly address the local inflammation. Massaging the site with scented oils (choice D) can potentially introduce more irritants and should be avoided in cases of inflammation.
