A client has a prescription to take guaifenesin (Humibid) every 4 hours, as needed. The nurse determines that the client understands the most effective use of this medication if the client states that he or she will:

  • A. Watch for irritability as a side effect.
  • B. Take the tablet with a full glass of water.
  • C. Take an extra dose if the cough is accompanied by fever.
  • D. Crush the sustained-release tablet if immediate relief is needed.
Correct Answer: B

Rationale: Guaifenesin is an expectorant used to help loosen mucus and make coughs more productive. Taking it with a full glass of water helps decrease the viscosity of secretions, making it easier to expel mucus from the respiratory tract. It is important not to crush sustained-release tablets, as this can alter the intended release of the medication and lead to potential adverse effects.
