A nurse is caring for a patient with a central venous catheter (CVC) who develops signs of a catheter-related bloodstream infection (CRBSI). Which nursing intervention should be implemented first?

The nurse notices increased temperature, chills, and purulent drainage at the CVC insertion site.

Notify the healthcare provider immediately for prompt medical evaluation and treatment decisions, as CRBSI requires coordinated care. Other interventions depend on provider orders.

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing action when a patient with a Central Venous Catheter (CVC) shows signs of a Catheter-Related Bloodstream Infection (CRBSI). The core principle is nursing scope of practice and the sequence of actions in a suspected infection. While all actions are important, the nurse must first initiate the chain of command to ensure a proper diagnosis and treatment plan is established.

Answer Rationale: Key Point! The correct answer is to Notify the healthcare provider immediately. This is the priority because the nurse's assessment (fever, chills, purulent drainage) strongly suggests a CRBSI, which is a serious, potentially life-threatening condition. The definitive diagnosis and decision to remove the catheter, obtain specific cultures, or start antibiotics require a provider's order. The nurse's first critical role is to communicate this urgent finding to initiate the medical management process.

Distractor Analysis:
Watch out for confusion! Obtain blood cultures (Option 1) is a crucial diagnostic step, but it is typically done after notifying the provider and receiving the order. The nurse may prepare for this, but initiating communication comes first.
Watch out for confusion! Remove the central venous catheter immediately (Option 2) is often the definitive treatment for a confirmed CRBSI, but this is not an independent nursing action. Catheter removal requires a provider's order. Premature removal without a plan for vascular access or cultures can hinder diagnosis.
Watch out for confusion! Administer prescribed antibiotics (Option 4) is incorrect because antibiotics are not yet prescribed. The scenario does not state there is a standing order. Administering medication through a potentially infected catheter without a confirmed order and before obtaining cultures could be harmful and mask the source of infection.

Related Concepts: This scenario integrates infection control, aseptic technique for CVC care, and nursing prioritization (ABCs and urgency). Remember, for potential systemic infections, assessment and communication precede independent intervention.

Concept SummaryCRBSI Signs: Fever, chills, tachycardia, hypotension, purulent drainage, erythema, tenderness at site. • Nursing Priority: Recognize signs → Notify provider → Follow orders for diagnostics (cultures) and treatment (catheter removal, antibiotics). • Diagnostic Gold Standard: Paired blood cultures (from CVC and peripheral vein) showing the same organism, with the CVC culture becoming positive sooner.

Side-by-Side Comparison!
ActionPriority/WhenRationale
Notify ProviderFIRST. Upon suspicion of CRBSI.Initiates the medical diagnosis and treatment plan. Nurse cannot order cultures, removal, or antibiotics.
Obtain Blood CulturesAfter provider order. Before antibiotics if possible.Essential for identifying the causative organism and guiding antibiotic therapy.
Catheter RemovalAfter provider order, often for confirmed CRBSI.Removes the source of infection. May be delayed if no other vascular access is available.


Anatomy, Physiology & Pharmacology PointsPathophysiology: Microorganisms (often skin flora like Staphylococcus aureus or epidermidis) colonize the catheter hub or skin entry site, migrate along the catheter, and enter the bloodstream, causing sepsis. • Pharmacology: Empiric broad-spectrum IV antibiotics (e.g., Vancomycin for MRSA coverage) are started after cultures are drawn, then tailored based on culture and sensitivity results.

Memory TipsAcronym: N.O.R.A. for suspected line infection: Notify provider, Obtain cultures (per order), Remove catheter (per order), Administer antibiotics (per order). • Think: "See something (signs of infection), Say something (to the provider)."

High-Frequency NCLEX Topics NCLEX loves testing priority-setting and delegation. Questions on CVC care and infection are common. Remember: Assessment and communication are almost always higher priority than performing a task when a new, serious problem is identified.

Watch Out for Question Variations! • Variation 1: "The nurse obtains an order for blood cultures. Which action should the nurse take next?" → Answer: Draw one set from the CVC and one set from a peripheral vein simultaneously. • Variation 2: "Which finding requires immediate catheter removal?" → Answer might shift to signs of Watch out for confusion! catheter-related thrombosis (sudden extremity swelling, pain) or air embolism (acute dyspnea, chest pain), where removal is more urgently life-saving.

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: Mr. Johnson, 68, is on your medical-surgical unit day 5 post-op. He has a right subclavian CVC for IV antibiotics and TPN (Total Parenteral Nutrition). During your morning assessment, he says he feels "achy and cold." You note his temperature is 38.8°C (101.8°F), heart rate is 112 bpm, and the CVC dressing has a small amount of yellowish drainage. The site is slightly red and warm.

Nursing Intervention Strategy: 1. Immediate Assessment & Communication: Perform focused assessment (vitals, full site inspection, mental status). Immediately call the covering provider or hospitalist using SBAR (Situation, Background, Assessment, Recommendation) format: "S: Mr. Johnson has new fever and purulent drainage at his CVC site. B: Post-op day 5, on TPN. A: Temp 38.8, HR 112, site erythematous with purulent exudate. R: I recommend an order for paired blood cultures and evaluation for line removal." 2. Prepare for Orders: While awaiting callback, gather supplies for blood culture draws (sterile kits, chlorhexidine swabs) and prepare the patient. 3. Implement Orders: Once orders are received: • Draw blood cultures as ordered (CVC and peripheral). • Assist with or prepare for catheter removal if ordered. • Administer prescribed IV antibiotics, often through a new peripheral IV if the CVC is suspected. • Send the catheter tip for culture if it is removed. 4. Monitor & Educate: Monitor for signs of worsening sepsis (hypotension, tachypnea, confusion). Educate the patient on the plan and importance of reporting any new symptoms.

Patient Safety and Precautions: • Never administer medication through a catheter you suspect is infected unless specifically ordered to do so (rare). • Use strict aseptic technique during any manipulation of the CVC. • Document findings objectively: "2x2 cm area of erythema, moderate seropurulent drainage, patient c/o chills."

Nursing Procedure & Medication Flow Obtaining Paired Blood Cultures: 1. Perform hand hygiene, don gloves. 2. Peripheral Stick First: Cleanse site with chlorhexidine for 30 sec, let dry. Draw required volume. 3. CVC Draw: Scrub the catheter hub with chlorhexidine for 15 sec. Use a sterile syringe to withdraw and discard 5-10 mL of blood (to clear the line of potential contaminants), then draw the culture sample into the bottles. 4. Label bottles clearly with source (e.g., "Peripheral R Arm," "CVC"). Send stat.
Medication Note: If antibiotics are ordered to be given through the CVC before removal, ensure the dose is drawn up with a new, sterile syringe after the blood discard sample is taken.

A Word from Your Senior Nurse "In the real world, trust your gut. If a patient with a central line 'just doesn't look right' and has a fever, think 'line infection' until proven otherwise. Your quick recognition and communication are what trigger the entire life-saving response. On the NCLEX and in practice, remember you are the eyes and ears. You don't have to have all the answers, but you must know who to tell and when to sound the alarm. That's what keeps patients safe."
