Aclient diagnosed with heart failure presents with a temperature of 99.1° f, pulse 100 beats/minute, respirations 42 breaths/minute, bp 110/50 mm hg; crackles in both lung bases; nausea; and pulse oximeter reading of 89%. which finding indicates a need for immediate attention?
(a)- lung's congestion
(b)- heart failure
(c)- brain haemorrhage
(d)- none of these
