Nokea
A nurse is caring for a client who has just had a central venous access line inserted. Which action should the nurse take next?
- A. Begin the prescribed infusion via the new access
- B. Ensure an x-ray is completed to confirm placement.
- C. Check medication calculations with a second RN.
- D. Make sure the solution is appropriate for a central line
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.

A nurse evaluates a clients arterial blood gas values (ABGs): pH 7.30, PaO2 86 mm Hg, PaCO2 55 mm Hg, and HCO3 22 mEq/L. Which intervention should the nurse implement first?
- A. Assess the airway.
- B. Administer prescribed bronchodilators.
- C. Provide oxygen.
- D. Administer prescribed mucolytics
Correct Answer: A
Rationale: The correct answer is A: Assess the airway. The nurse should prioritize airway assessment as the client's ABGs indicate respiratory acidosis (low pH, high PaCO2). This suggests potential airway obstruction or inadequate ventilation. Ensuring a patent airway is crucial for adequate oxygenation. Administering bronchodilators (B) or mucolytics (D) may help with airway clearance but should come after ensuring a clear airway. Providing oxygen (C) is important, but addressing the underlying respiratory acidosis by first assessing the airway is the priority in this situation to prevent further deterioration.
You are caring for a 65-year-old male patient admitted to your medical unit 72 hours ago with pyloric stenosis. A
nasogastric tube placed upon admission has been on low intermittent suction ever since. Upon review of the mornings
blood work, you notice that the patients potassium is below reference range. You should recognize that the patient may
be at risk for what imbalance?
- A. Hypercalcemia
- B. Metabolic acidosis
- C. Metabolic alkalosis
- D. Respiratory acidosis
Correct Answer: C
Rationale: The correct answer is C: Metabolic alkalosis. Pyloric stenosis can lead to vomiting, causing loss of gastric acid and chloride ions, leading to metabolic alkalosis. Low potassium levels are common in metabolic alkalosis due to potassium shifting into cells to compensate for the alkalosis. Hypercalcemia (choice A) is not associated with pyloric stenosis. Metabolic acidosis (choice B) typically presents with low pH and bicarbonate levels. Respiratory acidosis (choice D) is caused by impaired gas exchange in the lungs, not related to pyloric stenosis.
A nurse is caring for a client who has the following laboratory results: potassium 3.4 mEq/L, magnesium 1.8 mEq/L, calcium 8.5 mEq/L, sodium 144 mEq/L. Which assessment should the nurse complete first?
- A. Depth of respirations
- B. Bowel sounds
- C. Grip strength
- D. Electrocardiography
Correct Answer: A
Rationale: The correct assessment for the nurse to complete first is A: Depth of respirations. Potassium and magnesium levels are crucial electrolytes that can affect cardiac function. Hypokalemia (low potassium) and hypomagnesemia (low magnesium) can lead to cardiac dysrhythmias. Checking the depth of respirations can provide valuable information on the client's respiratory status and potential respiratory distress due to electrolyte imbalances. This assessment takes precedence as addressing respiratory issues promptly is essential to prevent further complications. Assessing bowel sounds (B), grip strength (C), and electrocardiography (D) are important but not as immediate as assessing respiratory status in this scenario.
You are working on a burns unit, and one of your acutely ill patients is exhibiting signs and symptoms of third spacing. Based on this change in status, you should expect the patient to exhibit signs and symptoms of what imbalance?
- A. Metabolic alkalosis
- B. Hypermagnesemia
- C. Hypercalcemia
- D. Hypovolemia
Correct Answer: D
Rationale: Rationale: Third spacing occurs when fluid shifts from the intravascular space to interstitial spaces, leading to hypovolemia. This results in decreased circulating blood volume, leading to signs of hypovolemia such as tachycardia, hypotension, and low urine output. Metabolic alkalosis, hypermagnesemia, and hypercalcemia are not directly related to third spacing and are not the expected imbalances in this scenario.
.A nurse assesses a clients peripheral IV site, and notices edema and tenderness above the site. Which action should the nurse take next?
- A. Apply cold compresses to the IV site.
- B. Elevate the extremity on a pillow.
- C. Flush the catheter with normal saline.
- D. . Stop the infusion of intravenous fluids.
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.
