A chemical reaction which is associated with a release of energy and thus, is associated with a negative free energy change is said to be an exergonic reaction.
An exergonic reaction owing to the negative free energy change is a spontaneous reaction.
The energy that is released in the exergonic reaction is usually observed in the form of heat and light.
The energy is released due to the breaking of the chemical bonds.
Therefore, on burning of the firewood the bonds between the glucose molecules break up which leads to the release of energy in the form of heat and light and this is thus, an example of an exergonic reaction.
Aspirin is contraindicated in a patient who is on oral anticoagulant medication because aspirin intensifies the action of the anticoagulant, which results in bleeding
Bleeding from shaving cuts may be difficult to control, so the patient should be advised to use an electric razor only
Patients who are on oral anticoagulant medication have difficulty controlling bleeding from injuries or external hemorrhage
The nurse should teach the patient techniques such as the application of pressure to control bleeding
Dental extraction may cause bleeding, which may be uncontrollable for a patient who is on anticoagulant medication, so patients on such type of medication should inform the dentist before starting the treatment
