Which over-the-counter medication is used to thin mucus and move secretions up and out of the respiratory tract?

  1. Expectorants

  2. Antihistamines

  3. Nasal decongestants

  4. Antipyretics

The correct answer is: Expectorants

Expectorants are the only option that specifically targets thinning mucus and promoting respiratory secretions. Antihistamines and nasal decongestants may help with symptoms of congestion, but do not directly address mucus thinning. Antipyretics help reduce fever and will not have an effect on respiratory secretions.
