92 yr old throat is gurgleing she is sick with a cold and now her throat sounds like she is gargleing with water for 2 days now. She eats a little and drinks a little. But sounds like she needs to cough. What can I do?

This . This sounds like she is dealing with a lot of mucous that she can't clear (cough up). In a case such as this a medication called an expectorant can be tried. Common medications for this are Mucinex (guaifenesin) or any cold medication with the initials dm behind it; this stands for dextromethorphan. Also, encorage her to drink more fluids and use a cool mist vaporizer, especially at night. If she has fever, shortness of breath, or her symptoms do not improve with the above measures, she needs to be evaluated by a medical professional.
