A client has been receiving a cough medicine with guaifenesin for 48 hours. Which nursing diagnosis would this medication best address?
1. Airway Clearance, Ineffective related to large amount of tenacious mucus
2. Perfusion: Gastrointestinal, Risk for Ineffective related to abdominal distension from gas buildup in stomach.
3. Gas Exchange, Impaired related to inability to discharge carbon dioxide
4. Pain, Acute related to swollen tonsils and discomfort rated at 7 on 0–10 VAS
Correct Answer: 1
Rationale 1: Guaifenesin is an expectorant. It helps move thick mucus by increasing its production.
Rationale 2: Guaifenesin does not affect perfusion.
Rationale 3: Guaifenesin does not act at the alveolar level.
Rationale 4: Guaifenesin does not relieve pain.
Global Rationale: Expectorants reduce the thickness or viscosity of bronchial secretions, thus increasing mucus flow that can then be removed more easily by coughing. The only commonly used OTC expectorant is guaifenesin (Mucinex). It does not affect perfusion or pain and does not act at the alveolar level.
