The registered nurse is teaching a nursing student about care for a patient who is on oral warfarin therapy. Which statement made by the nursing student indicates the need for further teaching?
1. "I will suggest that the patient use aspirin for pain."
2. "I will warn the patient to shave only with an electric razor."
3. "I will teach the patient techniques to control external hemorrhage."
4. "I will teach the patient to inform his or her dentist about the medication therapy."

1) option is correct

Explanation:

Aspirin is contraindicated in a patient who is on oral anticoagulant medication because aspirin intensifies the action of the anticoagulant, which results in bleedingBleeding from shaving cuts may be difficult to control, so the patient should be advised to use an electric razor onlyPatients who are on oral anticoagulant medication have difficulty controlling bleeding from injuries or external hemorrhageThe nurse should teach the patient techniques such as the application of pressure to control bleedingDental 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
