NCLEX COPD and asthma chapter: controlled oxygen, life-threatening asthma cues, rescue versus controller inhalers, and spacer technique.

Obstructive airway items ask two practical skills: give enough oxygen without harming a COPD retainer, and put the right inhaler in the right order when the client is tight and scared.

SituationPriority idea
COPD exacerbation, SpO2 lowControlled O2 per order/target; upright position; nebulizers/meds as ordered; watch mentation and CO2 retention cues
COPD on unexpectedly high O2 becoming sleepyReassess oxygen; somnolence can signal rising CO2
Severe asthma after treatmentCompare work of breathing, wheeze, SpO2, speech; silent chest/fatigue = escalate
Home COPD teachingStop smoking, vaccines, breathing techniques, infection warning signs

Safety

If wheeze disappears while the asthmatic client becomes exhausted and quiet, treat that as deterioration, not improvement.

Inhalers: rescue, controller, technique

Medicine roleExamples on examsJob
Rescue / quick reliefAlbuterol (SABA)Acute bronchospasm
Controller / maintenanceInhaled corticosteroid (fluticasone), montelukastPrevent inflammation; not acute rescue
  1. Shake the MDI as directed.
  2. Attach spacer; lips sealed on mouthpiece.
  3. Actuate once; inhale slowly and deeply.
  4. Hold breath briefly; wait between puffs as taught.
  5. If a steroid inhaler is also due, take the bronchodilator first, then the steroid; rinse mouth afterward.

  • Expected albuterol effects can include tremor and tachycardia; chest pain or severe reaction is reportable.
  • Thrush risk after inhaled steroids is why rinsing matters.
  • Montelukast is taken regularly for control, not for sudden severe wheeze.

Priority map

PictureFirst move

Asthma + silent/exhaustedEmergency escalation
Albuterol + ICS both dueBronchodilator first, then steroid, then rinse
Wrong spacer techniqueReteach seal, slow inhale, hold

Must know

  1. 1COPD hypoxic drive teaching on exams: start controlled low-flow oxygen (often 1–2 L/min NC or target SpO2 per order, commonly around 88–92% when ordered that way). High uncontrolled O2 can worsen CO2 retention in some COPD clients.
  2. 2Asthma attack: give rescue bronchodilator first. Silent chest, extreme fatigue, or rising CO2/falling LOC means life-threatening asthma — escalate.
  3. 3Albuterol = rescue. Inhaled corticosteroid = controller. Use bronchodilator before steroid inhaler when both are due.
  4. 4MDI with spacer: shake, seal lips on spacer, actuate, slow deep inhale, hold breath briefly as taught, rinse mouth after steroid inhalers.
  5. 5COPD home teaching: smoking cessation, vaccines, pursed-lip/diaphragmatic breathing, pacing activity, report sputum/fever changes.
  6. 6Montelukast is a controller pathway agent (leukotriene), not a rescue for acute wheeze.

Memory hooks

  • Rescue before rinse

    Open the airways with the rescue inhaler first, then take the inhaled steroid, then rinse the mouth.

  • Quiet chest is not calm chest

    In severe asthma, loss of wheeze with exhaustion can mean air is barely moving. That is worse, not better.

  • Low and slow O2 in COPD

    For many COPD exacerbations the exam expects controlled oxygen, not a casual 6 L jump without reassessment.

How it's tested

Stems ask which O2 to start for COPD at 86%, whether findings after asthma treatment are better or worse, inhaler order, or spacer steps. Distractors crank oxygen high without a plan, use the steroid inhaler for acute rescue, or skip mouth rinse after ICS.
