1.) The family practice physician examines a 56-year-old male established patient who comes to the office with his wife. The patient states that he has felt dizzy and lightheaded over the past three days. The patient is on medications for hypertension and states he has been tak­ing all as prescribed. The physician and the physician's nurse take the patient's blood pressure and find it to be 100/70 mm Hg, which is much lower than the patient's pressure as normally recorded. The patient had been taking antihypertensive medications of irbesartan (Avapro) and metoprolol (Toprol) with a low-dose diuretic. The physician is unable to determine which medication was the cause but is certain the patient's symptoms of vertigo and light-headedness are the side effects of the antihypertensive medications. New prescriptions are issued for adjusted dosages of the medications, and the patient is advised to go to the emergency department and call this physician if the symptoms get worse over the next 24 hours.

2.) The patient, a 35-year-old man, is brought to the emergency department (ED) by friends who report that the patient has chest pain. Upon questioning, the patient admitted to being a cocaine addict and to having used cocaine several times over the past 24 hours. The patient stated "maybe I overdosed," as he experienced chest pain on a previous occasion when he used more cocaine than he normally used. The patient is placed on telemetry in the ED and is later admitted to a telemetry bed on a nursing unit. Further cardiovascular testing finds no evidence of an acute myocardial infarction or respiratory disease; however, it is determined that the patient has hypertension that had never been treated. The physician determines that this event is a cocaine overdose that occtmed with the consequence of chest pain. The patient is also treated for hypertension and is strongly advised to continue the antihypertensive medica­tions and to seek help to overcome the cocaine addiction, as the two conditions have serious consequences on his long-term health. A referral is given to the local community mental health center, which offers a drug counseling service. The patient agrees and is discharged accompa­nied by his brother.
