A nurse is taking care of a patient who has just had a central venous access line inserted. What is the next step the nurse should ensure is completed?
Verify that the solution is suitable for a central line.
Double-check medication calculations with another RN.
Confirm placement with an x-ray.
Initiate the prescribed infusion via the new access.
The Correct Answer is C
Choice A rationale:
While verifying the suitability of the solution for a central line is important, it is not the immediate next step after insertion. Solutions that are incompatible with central lines can cause damage to the catheter or precipitate in the bloodstream, leading to serious complications. However, confirming placement takes priority to ensure the line is correctly positioned before any infusion is initiated.
Choice B rationale:
Double-checking medication calculations is a crucial safety measure, but it is not the most urgent step after central line insertion. Medication administration can only occur after confirming proper placement to avoid unintended infusion into incorrect sites or tissues, potentially leading to tissue damage or ineffective treatment.
Choice D rationale:
Initiating the prescribed infusion via the new access is the desired outcome, but it cannot be done before confirming placement. Infusing medications or fluids through a misplaced line can have severe consequences, such as:
Infiltration of medications into surrounding tissues, causing inflammation, pain, and potential necrosis.
Administration of medications into unintended areas, such as the pleural space or the vasculature of the head and neck, leading to potentially life-threatening complications.
Delay in the delivery of necessary medications or fluids if the line is not positioned correctly within the central venous system.
Choice C rationale:
Confirming placement with an x-ray is the essential next step to ensure the central line is in the correct position within the central venous system. This verification is crucial for several reasons:
Prevention of complications: Misplaced central lines can cause serious complications, such as pneumothorax (collapsed lung), hemothorax (blood in the pleural space), arrhythmias (irregular heartbeats), and nerve damage.
Accurate medication and fluid delivery: Proper placement ensures that medications and fluids are delivered directly into the central circulation, allowing for rapid and effective distribution throughout the body.
Safe and effective infusion: X-ray confirmation provides visual evidence of the line's position, guiding subsequent infusion practices and reducing the risk of errors.
Early identification of malposition: If the x-ray reveals a misplaced line, adjustments can be made promptly to prevent potential complications and ensure appropriate infusion.

Correct Answer is A
Explanation
Choice A rationale:
Prednisone is a corticosteroid that suppresses the body's natural production of cortisol. Cortisol is a hormone that is essential for life, and it plays a role in many important bodily functions, including:
Regulating blood sugar levels Maintaining blood pressure Reducing inflammation Responding to stress
When a person takes prednisone for a long period of time, their body begins to rely on the medication to provide cortisol. If the medication is stopped suddenly, the body cannot produce enough cortisol on its own, which can lead to a life-threatening condition called adrenal insufficiency.
Adrenal insufficiency can cause a variety of symptoms, including: Extreme fatigue
Weakness Dizziness Nausea Vomiting Abdominal pain Confusion
Loss of consciousness
To prevent adrenal insufficiency, it is important to taper off prednisone slowly over a period of time. This allows the body to gradually adjust to producing cortisol on its own.
Here are some additional details about why prednisone should never be discontinued abruptly: The risk of adrenal insufficiency is highest when prednisone has been taken for more than 3 weeks. The longer a person has been taking prednisone, the slower the taper should be.
It is important to follow the tapering instructions provided by the healthcare provider.
If a person experiences any symptoms of adrenal insufficiency, they should seek medical attention immediately.
Correct Answer is B
Explanation
Choice A rationale:
A serum sodium level of 134 mEq/L (134 mmol/L) is mildly low, but this level of hyponatremia is not typically associated with significant cognitive impairment.
Symptoms of hyponatremia, such as confusion, lethargy, and seizures, usually occur when sodium levels are 125 mEq/L or lower.
However, it's important to monitor this patient for any changes in cognitive status as hyponatremia can worsen and lead to more severe symptoms.
Choice C rationale:
A patient who underwent an open cholecystectomy two days ago may experience some cognitive impairment due to the effects of anesthesia and pain medications.
However, this type of impairment is usually temporary and resolves within a few days.
It's important to assess for cognitive impairment in this patient, but it is not the most urgent priority.
Choice D rationale:
A 32-year-old patient with a 20-pack-year history of smoking is at risk for cognitive impairment due to the long-term effects of smoking on the brain.
However, this risk is typically not as immediate as the risk of cognitive impairment following a stroke.
It's important to educate this patient about the risks of smoking and encourage smoking cessation, but it is not the most urgent priority in terms of cognitive assessment.
Choice B rationale:
An 88-year-old patient who had a hemorrhagic stroke three days ago is at the highest risk for cognitive impairment among the given options.
Hemorrhagic stroke involves bleeding in the brain, which can damage brain tissue and lead to cognitive deficits.
The risk of cognitive impairment is particularly high in older adults, as they may have less cognitive reserve to compensate for the damage caused by the stroke.
Early assessment and intervention for cognitive impairment are crucial for optimizing recovery and quality of life in stroke patients.
Prompt evaluation for cognitive impairment is essential to identify any deficits and initiate appropriate interventions to support the patient's cognitive function and recovery.
