What to do first
1. Determine whether symptoms are acute or maintenance-control related.
2. For acute bronchospasm, albuterol is the rescue pattern.
3. Salmeterol is long-acting maintenance therapy and is not for immediate relief of acute symptoms.
Albuterol vs Salmeterol NCLEX Priority Sheet
Bronchodilator comparison questions test SABA rescue use, LABA maintenance use, acute symptom treatment, inhaled corticosteroid pairing, tremor, tachycardia, and potassium shifts.
Study aid - not medical advice. Not a clinical decision tool. For NCLEX pharmacology review only.
Hold If
Notify the provider for chest pain, severe tachycardia, worsening wheeze after use, poor rescue response, increasing rescue inhaler need, or salmeterol being used as a rescue inhaler.
Do not use salmeterol alone for asthma control unless part of the ordered regimen with appropriate controller therapy.
Labs to Watch
Monitor respiratory status, SpO2, peak flow if used, HR, tremor, and symptom response.
High-dose beta agonist therapy can lower potassium; potassium may be checked in severe exacerbations or high-risk patients as ordered.

NCLEX Review Notes
Key Difference
Albuterol: SABA; quick relief/rescue for acute bronchospasm.
Salmeterol: LABA; maintenance control; slower onset and not for acute symptoms.
NCLEX memory rule: short-acting = rescue; long-acting = control.
Salmeterol: LABA; maintenance control; slower onset and not for acute symptoms.
NCLEX memory rule: short-acting = rescue; long-acting = control.
NCLEX Trap
Trap: a patient says, 'I use salmeterol whenever I have sudden wheezing.'
Correction: salmeterol is not a rescue inhaler. Teach use of prescribed rescue medication and notify the provider if rescue use is increasing.
Correction: salmeterol is not a rescue inhaler. Teach use of prescribed rescue medication and notify the provider if rescue use is increasing.
Side Effects
Beta-agonist effects: tremor, nervousness, palpitations, tachycardia, headache, and possible hypokalemia at high doses.
Safety clue: chest pain or severe tachycardia needs prompt assessment.

Mini Quiz
Question: Which inhaler does NCLEX expect for sudden wheezing: albuterol or salmeterol?
Answer: albuterol. Salmeterol is a long-acting maintenance medication, not immediate rescue therapy.
Answer: albuterol. Salmeterol is a long-acting maintenance medication, not immediate rescue therapy.
