NURS 4526 Acute Week 2
Test With Solution
Effective Gas Exchange - ANSWER Balance of Ventilation & Perfusion
- Ventilation (V): the amount of O2 reaching the alveoli
- Perfusion (Q): the amount of blood perfusing the alveoli capillaries
(requires sufficient amount of blood)
- V/Q ratio must be balanced (V/Q ratio of 1.0)
Signs & Symptoms of Hypoxemia - ANSWER Headache
Dyspnea (difficulty breathing/SOB)
Tachycardia
Working of Breathing
Confusion
Cyanosis
Blood Gas Measurements - ANSWER - Determines change in respiratory
status in acutely ill patients
- Measure lung function & tissue perfusion
, - Guides therapeutic interventions (i.e. O2 delivery, positive airway pressure,
mechanical ventilator settings for intubation)
Arterial blood gases - ANSWER Interpreting ABGs (ROME)
R = Respiratory
O = Opposite
(CO2 ↑ and pH ↓) = Respiratory Acidosis
(CO2 ↓ and pH ↑) = Respiratory Alkalosis
M = Metabolic
E = Equal
(HCO3 ↓ and pH ↓) = Metabolic Acidosis
(HCO3 ↑ and pH ↑) = Metabolic Alkalosis
Clinical Judgement Model - ANSWER Noticing (Assessment): What do I
notice?
Interpreting (Diagnosis/Planning): What does it mean?
Responding (Interventions): What should I do? What will I do?
Reflecting (Evaluation): What was the result of my actions & thinking?
Upper Airway Emergencies - ANSWER Croup syndromes
