ATI Fluid Electrolyte and Acid-Base Regulation Questions

Question 1 of 5

You are an emergency-room nurse caring for a trauma patient. Your patient has the following arterial blood gas results: pH 7.26, PaCO2 28, HCO3 11 mEq/L. How would you interpret these results?

Correct Answer: D

Rationale: To interpret the given ABG results: 1. pH <7.35 indicates acidosis. 2. PaCO2 <35 indicates respiratory alkalosis. 3. HCO3 <22 indicates metabolic acidosis. Therefore, the ABG results show metabolic acidosis (low pH, low HCO3) with compensatory respiratory alkalosis (low PaCO2). This means the body is trying to compensate for the metabolic acidosis by decreasing PaCO2 through hyperventilation. Option D is correct. Options A, B, and C are incorrect as they do not align with the ABG results and the principles of acid-base balance.

Question 2 of 5

A nurse teaches a client who is prescribed a central vascular access device. Which statement should the nurse include in this clients teaching?

Correct Answer: C

Rationale: Correct Answer: C Rationale: 1. Choice C is correct because it emphasizes the importance of cleaning connections before accessing the device to prevent infection. 2. Sterile technique during insertion cannot guarantee no risk of infection (Choice B). 3. Wearing a sling is unnecessary for a central vascular access device (Choice A). 4. The statement about not being able to take a bath is not accurate and is not a common restriction (Choice D).

Question 3 of 5

The nurse is preparing to insert a peripheral IV catheter into a patient who will require fluids and IV antibiotics. How should the nurse always start the process of insertion?

Correct Answer: C

Rationale: Correct Answer: C Rationale: Asking the patient about allergies to latex or iodine is crucial before starting the IV insertion process. This step ensures patient safety and prevents potential allergic reactions. Knowing the patient's allergies allows the nurse to select appropriate materials for the procedure, reducing the risk of complications. Summary of Other Choices: A: Leaving one hand ungloved is not recommended as it compromises infection control practices. B: Cleansing the skin with normal saline is important but should come after confirming allergies to latex or iodine. D: Removing excessive hair from the site is unnecessary and not a standard practice for starting the IV insertion process.

Question 4 of 5

You are making initial shift assessments on your patients. While assessing one patients peripheral IV site, you note edema around the insertion site. How should you document this complication related to IV therapy?

Correct Answer: C

Rationale: Correct Answer: C - Infiltration Rationale: 1. Infiltration occurs when IV fluid leaks into surrounding tissues, causing edema. 2. Documenting infiltration is important for appropriate management. 3. Air emboli, phlebitis, and fluid overload are unrelated to edema around IV site. Summary of Incorrect Choices: A. Air emboli: This is a serious condition caused by air entering the bloodstream, not related to edema. B. Phlebitis: Inflammation of the vein, usually presenting with redness and pain, not edema. D. Fluid overload: Excess fluid volume in the body, leading to symptoms like shortness of breath, not edema.

Question 5 of 5

You are caring for a patient admitted with a diagnosis of acute kidney injury. When you review your patients most recent laboratory reports, you note that the patients magnesium levels are high. You should prioritize assessment for which of the followin

Correct Answer: A

Rationale: Step 1: High magnesium levels can lead to hypermagnesemia, which can cause decreased neuromuscular function. Step 2: Diminished deep tendon reflexes are a sign of neuromuscular impairment, indicating potential hypermagnesemia. Step 3: Assessing for diminished deep tendon reflexes is crucial to monitor neuromuscular function in patients with high magnesium levels. Summary: A is correct because hypermagnesemia affects neuromuscular function. B, C, and D are incorrect as they do not directly relate to the effects of high magnesium levels.
