◉Alkalosis:.
Answer: (see graphic)
◉Acidosis:.
Answer: (see graphic)
◉Potassium Levels in Acidosis:.
Answer: - K+ = Elevated
◉Respiratory Acidosis:.
Answer: - low pH, high CO2
◉Respiratory Alkalosis:.
Answer: - high pH, low CO2
◉Metabolic Acidosis:.
,Answer: - low pH, low HCO3
◉Metabolic Alkalosis:.
Answer: - high pH, high HCO3
◉Interpret this ABG:
- ph 7.37

- Bicarbonate 30 mEq/L.
Answer:
◉Rescue Breathing Position:.
Answer: - Side lying position
◉Airway Management:.
Answer: - Essential nursing skills that maintain natural or artificial
airways for compromised clients
◉NPPV Machine:.
Answer: - Non Invasive Positive Pressure Ventilation
◉CPAP/BiPap Machine Overview:.
, Answer: - Indications: acute COPD, cardiogenic pulmonary edema,
early hypoxemic failure in immunocompromised patients, obstructive
sleep apnea, and to prevent re-intubation
- Contraindications: apnea, cardiovascular instability or hypotension,
dysrhythmias, MI, claustrophobia, somnolence, high aspiration risk,
copious secretions, GI surgery, craniofacial trauma, and burns
◉Endotracheal Intubation (ET):.
Answer: - Insertion of endotracheal tube through the mouth or
nose...preferred route to reduce infections
- Indications: maintain airway, remove secretions, prevention aspiration,
and provide mechanical ventilation
◉Intubation Equipment:.
Answer: - Ambu Bag connected to oxygen
- Laryngoscope & endotracheal tubes
- Suction equipment
- Ventilator
- Device or tape to secure ETT
◉Rapid Sequence Intubation (RSI):.
Answer: - Giving medications to sedate (induce) and temporarily
paralyze a patient and then performing orotracheal intubation.
- Eg. propofol, midazolam, short term paralytics, or fentanyl
- Sedate -> pain medicine -> short term paralytic
