Practice questions
- In the post hoc CLEAN 3 analysis of PIVC insertion sites, how many catheters with a known insertion site and sent for quantitative culture were included?
- In the CLEAN 3 post hoc analysis, which finding met the study's stated definition of PIVC colonization?
- For cubital fossa PIVC insertion, the adjusted hazard ratio for colonization and/or local infection was 1.64 (95% CI 0.92–2.93). Which interpretation is most accurate?
- In the same analysis, which insertion site had an adjusted HR of 2.11 (95% CI 1.08–4.13) for PIVC colonization and/or local infection?
- Based on the authors' conclusions from the PIVC site analysis, which site-selection approach is most appropriate when feasible?
- Which statement correctly distinguishes the two catheter outcomes reported in the CLEAN 3 site analysis?
- An older man has a pulsatile upper-arm mass, arm pain, and rapidly progressive median nerve palsy. In the reported unusual case, which imaging finding clarified the diagnosis?
- In the reported case of an ulnar artery aneurysm proximal to the cubital fossa, what was the initial duplex ultrasound impression?
- Which feature made the ulnar artery aneurysm in the case report anatomically unusual?
- Which operative management was reported for the true ulnar artery aneurysm proximal to the cubital fossa?
- What does the reported association of a pulsatile arm mass with median nerve palsy most directly illustrate?
- A deep cubital-region wound cannot be closed primarily and has vital structures exposed. Which reconstructive objective was emphasized in the reported flap series?
- In the 17-patient cubital-region defect series, which flap was used most frequently?
- Which distribution correctly accounts for all 17 reconstructions in the cubital-region defect series?
- Which outcome was reported after flap coverage of the cubital-region defects?
- A surgeon is considering whether results from the 17-patient cubital flap series establish that TDAP flaps are superior to SLDM or reversed lateral arm flaps. Which conclusion is justified?
