70 Free CNA Practice Exam Online Questions and Answers on Respiratory Disorders

respiratory distress

• reduced oxygenation of tissues
• reduced oxygenation of arterial blood
• clinical manifestation, not a diagnosis, r/t difficulty breathing
• Blood test necessary for Dx of Resp Failure

What are early signs of acute respiratory failure?

• deficient amount of oxygen in the blood; leads to hypoxia if not treated
• clinical manifestation, not a diagnosis, r/t difficulty breathing
• Restlessness, Irritability, Fatigue, Headache, Dyspnea, Tachycardia, Adventitious breath sound.
• resp pharm: treat infx, help reduce swelling and exudate clogging up airways

nitrates

• Blood test necessary for Dx of Resp Failure
• tx of pulm edema to reduce preload and afterload
• tx of pulm edema to support perfusion by increasing CO
• tx of pulm edema to decreas anxiety

1

• phase of ARDS (1,2,3): increased capillary permeability, increased fluid in interstitial spaces (not alveoli), pt becoming symptomatic (anxious, reports of dyspnea)
• phase of ARDS: irreversible deposition of fibrin into lungs (pulm fibrosis, decreased lung compliance), worsening hypoxemia, V/Q imbalance, profound arterial hypoxemia
• phase of ARDS (1,2,3): full pulmonary edema, massive inflammatory response, damage to basement membrane and alveolar epithelium, increased chasm between capp membrane and alveoli
• phase of ARDS (1,2,3): endothelial changes, inflammatory changes in alveloi, pt may be asymptomatic except for underlying cause

ABGs

• Blood test necessary for Dx of Resp Failure
• refractory to supplemental O2
• movement of air in and out of the lungs
• reduced oxygenation of tissues

What are causes of metabolic acidosis?

• Renal failure, DKA, Salicylate drug overdose. These conditions result from acid gain.
• reduced oxygenation of tissues
• resp pharm: treat infx, help reduce swelling and exudate clogging up airways
• An insufficiency of oxygen in the body's tissues.

shift to the right

• Extreme V/Q mismatch resulting in the blood exiting the heart without O2.
• tx of pulm edema to support perfusion by increasing CO
• Oxyhemoglobin Shift CMs: shallow breathing, barely responsive, low O2 sat
• Acute lung injury, most severe form of ARF

shift to the right

• Acute lung injury, most severe form of ARF
• INCREASED CO2 (greater than 45mm Hg) and DECREASED pH (less than 7.35), Telling us it's a VENTILATION problem, pt either not breathing enough or has an airtrapping diagnosis such as asthma or COPD
• tx of pulm edema to support perfusion by increasing CO
• Decreased Hgb affinity to O2, occurs with decreased pH, increased pCO2, temp and 2,3 DPG.

Perfusion, Positioning, Protect lung ventilation, Protocol weaning, Prevent complications

• reduced oxygenation of tissues
• refractory to supplemental O2
• 5 Ps of ARDS therapy
• PaCO2 > 50 mmHg

signs and symptoms of hypercapnia

• cause of ventilatory failure characterized by decreased CNS drive or mechanical disruptions
• Respiratory: dyspnea, decreased respiratory rate or increased rapid rate with shallow respirations cerebral: morning headache, disorientation, progressive somnolence, coma (late) cardiac: dysrhythmias, hypertension, tachycardia, bounding pulse - Neuromuscular: muscle weakness, decreased deep tendon reflexes, tremor, seizures (late)other: pursed lip breathing, use of tripod position
• Tx of ARDS which reduces systemic inflammation, increases pulmonary function, decreases duration of mechanical ventilation and SAVES LIVES
• resp failure characterized by a rise in Paco2 (hypercapnia) that occurs when the respiratory load can no longer be supported by the strength or activity of the system

What are late signs of acute respiratory failure?

• Tx of ARDS which reduces systemic inflammation, increases pulmonary function, decreases duration of mechanical ventilation and SAVES LIVES
• tx of pulm edema to support perfusion by increasing CO
• Restlessness, Irritability, Fatigue, Headache, Dyspnea, Tachycardia, Adventitious breath sound.
• Lethargy, Kussmal breathing pattern, Diaphoresis, Use of accessory muscles, Decreased breath sounds.

shift to the left

• Oxyhemoglobin Shift CMs: rapid breathing, becoming fatigued, previously agitated
• movement of air in and out of the lungs
• common causes (2) of poor ventilation/good perfusion
• consists of three phases: exudative, proliferative, fibrotic
