VA-BC™ Vascular Access Decision Guide Study Guide

Apply it

An adult needs brief hydration with a peripherally compatible solution and has suitable forearm veins. Select a short peripheral catheter after assessing the treatment course, rather than choosing central access solely because it might last longer.

Apply it

A patient is offered a midline for a solution explicitly requiring central administration. Explain that the upper-arm insertion and longer catheter do not meet the central-tip requirement, and request a device plan compatible with the prescribed therapy.

Apply it

A newly inserted arm catheter is labeled PICC, but the placement record lacks tip confirmation. Before administering a solution requiring central delivery, obtain the required confirmation rather than relying on the device name or insertion site.

Apply it

A patient arrives with an implanted chest port and no external tubing. Prepare compatible non-coring access equipment and verify access function; do not approach the device as though an external catheter hub were already available.

Apply it

A patient needs one continuous compatible infusion and no additional simultaneous therapy. A single-lumen device meets the plan; requesting three lumens solely for unspecified future needs adds complexity without an identified treatment requirement in this case.

Apply it

Two devices can both provide the prescribed therapy, but one has a smaller outer diameter. After confirming suitable vessel dimensions and device performance, favor the smaller appropriate device rather than equating a larger catheter with better access.

Apply it

A port identification card confirms power capability, but the access needle's rating cannot be established. Delay power injection until a compatible rated needle and the remaining system requirements are verified for the planned contrast administration.

Apply it

A patient beginning chronic dialysis is being considered for indefinite catheter dependence. Recognize that immediate catheter access and permanent dialysis access are different decisions, and include preservation of future fistula or graft options in the treatment discussion.

Apply it

A clinically stable patient can take and absorb the prescribed oral treatment, and no other IV indication exists. Ask the treating team to reconsider the route before starting repeated cannulation attempts solely to preserve a routine admission practice.

Apply it

A patient needs several inpatient doses followed by an extended outpatient course. Assess the complete regimen and maintenance arrangements before device selection, rather than repeatedly replacing short-term access because each day's order is considered separately from the overall plan.

Apply it

Compare two mixed CLINIMIX formulations before additives: 4.25/5 contains 4.25% amino acids and 5% dextrose, with calculated osmolarity 675 mOsm/L; 4.25/10 contains the same amino acid concentration but 10% dextrose, with calculated osmolarity 930 mOsm/L. Which supports peripheral administration? The prescribing information permits peripheral or central administration of 4.25/5 but requires central administration of 4.25/10. Thus, a suitable short peripheral catheter may meet the route requirement for the first formulation, whereas the second requires a CVAD. An existing midline cannot satisfy that central requirement because its tip remains peripheral. These formulation values and restrictions appear in the [CLINIMIX prescribing information, sections 2.2, 3 and 5.6](https://dailymed.nlm.nih.gov/dailymed/fda/fdaDrugXsl.cfm?setid=dccff103-8695-400c-a15d-cc2fd078760a).

Apply it

An adult with advanced kidney disease needs central therapy. A clinician proposes subclavian placement because of its infection profile. Raise the stenosis concern and seek a site plan that accounts for future dialysis access and current mechanical risks.

Apply it

A patient reports multiple failed landmark attempts during previous admissions and needs peripherally compatible treatment. Arrange assessment by a clinician competent in ultrasound-guided peripheral access before accumulating avoidable attempts or selecting a central catheter solely because access is difficult.

Apply it

A patient reports an itchy rectangular rash beneath a previous dressing but no systemic symptoms. Identify the products used and inspect the distribution before selecting alternatives; do not automatically record every adhesive and antiseptic as the same allergy.

Apply it

Before arm access, a large superficial basilic vein remains partly open under compression, while an adjacent vein collapses completely. Avoid selecting the noncompressible vessel pending assessment for thrombosis. Evaluate the compressible alternative's diameter, depth, course and compatibility with the planned catheter and therapy; compressibility alone does not establish overall suitability.

Apply it

A colleague calculates 2 divided by 5 and reports that the catheter occupies 40% of the vein's area. Correct the interpretation: the diameter ratio is 40%, while the idealized area fraction is 0.4 squared, or 16%.

Apply it

A patient understands the infusion schedule but cannot manipulate the required connections because of hand weakness. Confirm whether a trained caregiver or home service can perform those tasks and ensure supplies and contact arrangements are established before discharge.

Apply it

A patient gives short answers in English but communicates fluently through a qualified interpreter. Discuss device options with that support and assess understanding directly, rather than assuming the language barrier requires a family member to make the decision.

Apply it

Two central sites are technically available, but one creates a significant patient-specific vascular concern. Present the infection and mechanical tradeoffs to the team and select using the full risk profile rather than one infection-prevention ranking.

Apply it

A clinician prepares supplies, handles a bedside control and then reaches for catheter connections while wearing gloves. Pause to restore appropriate hand hygiene and glove practice before device contact, rather than treating the unchanged gloves as continuing protection.

Apply it

A PICC tray includes sterile gloves and a small fenestrated drape, but no sterile gown or full-body drape is available. Complete the required barrier setup before insertion rather than treating peripheral entry as a reason to reduce precautions.

Apply it

The planned puncture site remains visibly wet after antiseptic application. Wait for the required drying before insertion and protect the prepared area, rather than puncturing immediately because the operator has already donned sterile gloves and the equipment is ready.

Apply it

While preparing a flush, a syringe tip touches the outside of a package. Replace the contaminated syringe before connection; continuing because the fluid is sterile would overlook contamination of the surface that joins the vascular access system.

Apply it

A patient has signed the form but says, 'I thought this was another ordinary blood draw.' Pause preparation, clarify the proposed catheter and its alternatives, and verify understanding before interpreting the signature as informed permission to proceed.

Apply it

The team prepares the right arm, but the documented plan specifies the left and the patient reports a prior right-sided problem. Stop the start of insertion and reconcile the intended site and relevant history before proceeding.

Apply it

A patient cannot comfortably maintain the proposed arm position because of shoulder pain. Adjust positioning and the comfort plan before sterile preparation, and confirm that the revised setup still allows the clinician to perform the planned insertion safely.

Apply it

After a vessel is marked, the patient shifts position before cannulation. Reassess and use real-time guidance during insertion rather than treating the earlier mark as a fixed map of the vessel's present location beneath the skin.

Apply it

A bright needle segment appears near the target vein, but the operator cannot distinguish the tip from the shaft. Stop advancement and adjust visualization to locate the tip before moving farther toward the vessel or nearby structures.

Apply it

A wire advances easily after neck-vein puncture, but its position in the intended vein has not been demonstrated. Pause before dilation and establish intravascular wire location rather than using smooth advancement as permission to enlarge the tract.

Apply it

A disinfected probe is ready with a sterile cover, but only a previously opened nonsterile gel bottle is present. Obtain sterile gel and complete the protected setup before bringing the probe into the sterile procedural field.

Apply it

A newly inserted PICC has brisk blood return, but no accepted tip-location result is recorded. Withhold initial use until the required confirmation is available and reviewed, especially before therapy that depends on appropriate central tip positioning.

Apply it

An observer notices that part of the sterile barrier setup is missing as the operator prepares to puncture. Use the checklist to pause and correct the omission before insertion instead of documenting the deviation after the device is placed.

Apply it

Shortly after chest central catheter placement, a patient develops new breathlessness and falling oxygen saturation. Initiate urgent assessment and escalation for a possible mechanical complication rather than proceeding with routine line use while waiting for symptoms to settle.

Apply it

A patient reports new tenderness beneath an opaque dressing, although its edges remain secure. Arrange appropriate direct site assessment instead of documenting the catheter as satisfactory solely because the covering is dry and the infusion pump is running.

Apply it

A central dressing applied yesterday is lifting and wet after bathing. Replace it using the appropriate aseptic process now, assess the site and review moisture protection rather than waiting until the scheduled dressing-change day later in the week.

Apply it

An adult short-term central-line dressing policy is proposed for a premature neonatal unit. Identify the population mismatch and the skin-injury restriction before adoption, rather than extending the adult recommendation solely because infection prevention is the same goal.

Apply it

After blood sampling, a clinician immediately reaches to attach another syringe. Ensure the connector receives the required preparation for that access and that the antiseptic dries, rather than assuming a previous scrub covers every connection in the episode.

Apply it

A unit replaces positive-displacement connectors with negative-displacement connectors. Its former routine was to finish flushing, disconnect and then clamp. Continuing that routine can allow disconnection-related reflux before the clamp closes. After verifying the new product instructions, teach staff to clamp before completing the flush and disconnecting, as specified for the negative-displacement example.

Apply it

A PICC's external segment is longer than the insertion baseline after a traction event. Pause use and arrange assessment of possible migration and tip position rather than retaping the catheter at the old measurement or assuming blood return proves safety.

Apply it

After teaching dressing protection, ask the caregiver to explain what they would do if it became wet or loose. If they plan to wait several days, reteach the response and check understanding again before completing discharge education.

Apply it

A patient's IV course is complete and the team confirms no remaining access indication. Arrange prompt removal and appropriate site care instead of retaining the functioning catheter for several additional days because obtaining access had originally been difficult.

Apply it

During a peripheral infusion, the patient notices swelling and tightness despite no pump alarm. Stop the infusion, identify the solution and assess for infiltration or extravasation before deciding device removal and further management for the affected tissue.

Apply it

A patient receiving vesicant anticancer therapy reports burning with new local swelling. Stop administration, call for assistance and retain the device for aspiration without flushing, then initiate the identified agent's extravasation pathway and document the assessment.

Apply it

A central infusion stops after the patient's tubing is repositioned. Inspect clamps and the full external pathway first. If a kink explains the interruption, correct it and reassess function before considering pharmacologic clearance for an unproven intraluminal obstruction.

Apply it

A previously patent lumen becomes obstructed after sequential administration of solutions later identified as incompatible. Review a possible chemical occlusion with the treating and pharmacy teams rather than automatically repeating a thrombolytic previously used for a different catheter problem.

Apply it

A CVAD accepts a gentle flush but repeatedly fails to yield expected blood return. Recognize a possible partial occlusion and assess its cause rather than labeling the catheter fully patent or treating it as a complete blockage.

Apply it

A patient with a PICC develops new unilateral arm swelling extending beyond the dressing area. Escalate for assessment of possible venous thrombosis and other causes rather than simply loosening tape or instilling a lumen-clearance drug as definitive treatment.

Apply it

A stable patient with a central catheter develops fever and symptoms suggesting another infection source. Assess both the patient and catheter and obtain the indicated evaluation rather than declaring a catheter-source bloodstream infection from fever alone.

Apply it

A non-tunneled central catheter is suspected of being infected, and a guidewire exchange is proposed to avoid another puncture. Identify the infection-related restriction and pursue an appropriate replacement plan rather than treating exchange as a universally safer option.

Apply it

After repeated dressing removal, a patient has superficial skin loss along an adhesive edge without drainage or systemic symptoms. Assess mechanical injury and improve skin protection and removal technique, while checking for additional findings that would alter the differential.

Apply it

A unit reports four CLABSIs over 2,000 central-line days. Calculate 4 divided by 2,000 multiplied by 1,000, giving 2 per 1,000 central-line days; do not substitute the unit's admission count or total patient days.

Apply it

A unit records 450 central-line days and 900 patient days in one month. Its utilization ratio is 0.50. Compare this exposure measure with clinical necessity reviews rather than calling it an infection rate or multiplying it by 1,000.

Apply it

Of 50 observed eligible insertions, 44 include every required bundle element. Complete adherence is 88%, even if each individual component exceeds 90%. Use the missing-element data to target improvement without relabeling incomplete encounters as fully compliant.

Apply it

A report compares two catheter products, but clinicians chose the newer product for patients with easier access. Identify the assignment as nonrandomized and consider selection bias rather than accepting a randomized-trial label based on the presence of comparison groups.

Apply it

A clinician has logged many insertions but repeatedly loses needle-tip visualization during assessment. Provide targeted feedback and supervised practice, then reassess the defined skill rather than granting independent practice solely because the numerical experience requirement has been reached.

Apply it

Before puncture, a patient who understands the discussion says they no longer want the proposed catheter. Stop, explore the reason and notify the treating team to discuss options rather than proceeding because the signed form is already in the chart.

Apply it

A catheter works after two unsuccessful attempts and one successful attempt. Document the actual attempt history, relevant findings and patient response along with final device information, so subsequent clinicians can interpret symptoms and plan future access appropriately.

Apply it

A replacement needle resembles the previous power-rated model, but its labeling does not confirm that capability. Verify the exact model's instructions and compatibility before power injection rather than relying on appearance, brand familiarity or another product's clearance document.

Apply it

A hospital patient's catheter fractures, and a fragment embolizes. An interventional radiologist removes the fragment and documents that removal was necessary to prevent permanent vascular damage. The patient recovers without lasting impairment. First classify the event: it meets the serious-injury definition because intervention was needed to prevent permanent damage. Next select the destination: with a known manufacturer, the hospital must report to that manufacturer within 10 work days of becoming aware of the reportable event. Recovery does not remove the reporting obligation, and definitive proof of device causation is unnecessary.

Apply it

A routine preference would open several unused device kits before assessing the patient. Complete the assessment and gather the appropriate equipment deliberately, while preserving required sterile supplies and recording charges accurately for the care and materials actually provided.
