Correct Answer: B

Rationale: Bronchospasm, cough, rhinitis, and bronchial obstruction are related to loss of bronchodilation of the respiratory tract and vasodilation of mucous membrane vessels so a sudden onset of a cough or difficulty breathing should be immediately reported to the health care provider.
