Quick answerContinue the prescribed dwell and reassess at
120 minutes.
Why this is correctCathflo labeling assesses catheter function at 30 minutes and, when still occluded, again at 120 minutes. Only after the first dose fails at 120 minutes may an equal second dose be considered.
Easy analogy or mental pictureGive the key time to work before trying the next authorized step.
Memory hookCathflo checks at 30, then 120.NCLEX decision ruleFollow the labeled intracatheter dwell and aspiration sequence; do not force a resistant line.
Why the other choices are wrongForceful flushing risks harm, a third dose exceeds the labeled sequence, and immediate removal skips the reassessment pathway.
