Nur 425 Exam 3 2024 Testbank

Normal HCO3 {Ans: 22-26 mEq/L}Treatment/interventions for metabolic alkalosis due to bicarbonate build up/acid loss: {Ans: Need to excrete bicarbonate/retain acids -D/C drugs causing imbalance (antacids, thiazide diuretics) -D/C NGT suction -Antiemetics -Acetazolamide (Diamox)}What is hypoxemia? {Ans: lack of oxygen in arterial blood}Types of devices for ICP Monitoring {Ans: Location (eg. Epidural, Subdural, Subarachnoid) Purpose - Trend an ICP waveform only -> fiberoptic catheter or subarachnoid bolt or screw - Drain CSF and trend ICP waveform ->Ventriculostomy/External ventricular Drain(EVD) ->catheter that can trend ICP and drain CSF if necessary}If a [pH, HCO3-, H+, CO2, Respiratory rate] were basic, would it be high or low? {Ans: pH: ↑ HCO3-: ↑ RR/depth: ↑ CO2: ↓}Compensation: How do the lungs help our bodies handle an acid base imbalance? {Ans: Regulates CO2: normal levels 35-45 mm Hg Metabolic Acidosis Problem: (↓pH) - triggers Hyperventilation (↑rate and depth of RR) = ↓CO2 = ↑pH Metabolic Alkalosis Problem: (↑pH ) - triggers Hypoventilation (↓rate and depth of RR) = ↑CO2 = ↓pH}
