Rule of B's for ABGs - if the pH and the Bicarb are Both in the same direction it is metaBolic normal pH normal Bicarb - pH: 7.35-7.45 Bicarb: 22-26 Kussmul respirations - MACkussmul= metabolic acidosis S&S of acid-base imbalance - as the pH goes, so goes my patient except for potassium UP: (alkolosis):decreased K+, highest risk for seizures DOWN: (acidosis): increased K+, highest risk for respiratory arrest causes of respiratory acid-base imbalance - lung=respiratory overvent or under...

PHARM EXAM 1 (MSN) PNS: cholinergic receptors 1. nicotinic (N): all ANS ganglia and medulla 2. nicotinic (M): neuromuscular junction 3. muscarinic: PNS organs site of action: PNS rx -synapse -rx alters synaptic transmission (AcH) SNS: Adrenergic receptors -alpha 1, alpha 2, beta 1, beta 2 -also effects epi/norepi, dopamine breakdown of AcH -via AChE or MAO 1. AcH=reuptake into nerve cell 2. degraded by MAO 3. diffusion of waste out of cell sites where Rx act/influ...
