Pathophysiology
Clinical meaning
ABG interpretation items test whether you connect assessment data to risk: what changes first, what needs escalation, and what teaching or orders are unsafe in context.
US RN (NCLEX-RN): Prioritize airway–breathing–circulation and unstable vs stable framing. Watch delegation traps: what must stay with the RN when the client is deteriorating vs what is appropriate for the UAP/LPN when stable and within competency.
Exam Focus
Exam relevance
Expect prioritization, monitoring, and safety—especially when the stem adds routine tasks alongside an abnormal finding. US: NCLEX-style who to see first and which order to question.
