Methenamine

The benzylchloride compound made in the previous recipe can be converted to piperonal or benzaldehyde using a chemical called hexamine [137 p817, 37 p700, 136]. Hexamine, also known as methenamine or hexamethylenetetramine, is a weird looking chemical that is easily made from formaldehyde but is better off being purchased. 

Methenamine and methenamine salts break down and form ammonia and formaldehyde, which are bactericidal. These dm are used for UTIs that are caused by susceptible microorganisms.

The nurse measures the fluid intake and output, especially when the primary health care provider orders an increase in fluid intake or when a kidney infection is being treated.
