A 64-year-old with chronic kidney disease undergoes percutaneous arterial catheterization for angiography. Six hours later, he has severe back pain and decreasing hematocrit. What is the most likely complication?
Contrast nephropathy
Local cellulitis
Retroperitoneal hemorrhage
ation: Retroperitoneal hemorrhage is a rare but critical complication of femoral arterial punc ting with pain and hemodynamic instability; prompt recognition is life-saving.
systematic review in a top vascular access journal uses a PICO framework and includes onl mized trials. Why is this methodological choice superior for practice guidelines?
ndomized trials minimize bias and PICO ensures focused, clinical relevance lusion criteria are always broad by default
CO emphasizes quantity over quality n-randomized trials add more detail
er: A
nation: Minimizing selection and confounding bias through randomized design ensures guidel mendations are robust and applicable.

Early cellulitis
Central vein occlusion resulting in classic collateral vein development
Answer: D
Explanation: Visible collateral circulation across the trunk in vascular access patients almost always signals chronic central vein occlusion.
A 68-year-old patient presents with severe sepsis and shock requiring both norepinephrine and intravenous antibiotics. After assessment, peripheral access is achieved using a 22G catheter. What is the greatest limitation of this access?
Inability to infuse vasopressors safely
Rapid flow rates for resuscitation
Insufficient for blood transfusion
Unsuitability for blood sampling
Answer: A
nation: Small, peripheral catheters (like 22G) are associated with higher risk of vasopressor asation injuries and are not ideal for vasopressor infusion; central access is preferred for suc ations.

pation and landmark technique rasound with sterile cover and gel
Infra-red vein finder technology nsillumination of the upper arm

A 1,200 g 26-week neonate with NEC requires aquapheresis for fluid overload (OI 28%, ECHO EF 32%). UF goal 8 mL/kg/h ??48 h. Veins <1 mm. Current 24-gauge PIV infiltrated. Which catheter and filter achieve 5???10 mL/min UF with <8% hemolysis?

6.5 Fr 12 cm double-lumen in right IJ; Baxter HF12 polysulfone 0.3 m??
7 Fr 15 cm triple-lumen in left brachial; NxStage Cartridge Express 0.6 m??
Answer: B
Explanation: Neonatal aquapheresis requires <10% extracorporeal volume (36 mL max); HF20 filter prime 18 mL + 8 cm lines 4 mL = 22 mL. 4 Fr femoral dual-lumen yields 8 mL/min at 20 mmHg. Polyarylethersulfone biocompatibility reduces complement activation vs polysulfone. Umbilical route risks portal thrombosis; brachial 7 Fr exceeds 45% vessel ratio causing occlusion.

During rounds, a patient voices concerns that their vascular access plan does not align with religious beliefs. What should the nurse advocate for?
Decline patient participation in planning
Continue with standard care regardless of beliefs
Escalate only if conflicts arise
Facilitate open dialogue and incorporate preferences
Answer: D
Explanation: Nurses have an ethical responsibility to advocate for patient preferences related to cultural and religious beliefs, incorporating them into individualized vascular access planning.
