The bony structures of the face include the vomer, mandible and six pairs of bones. Four pairs of sinuses (air-filled sacs) are the ethmoid, frontal, maxillary and sphenoid sinuses.
Patient Assessment
Dental Emergencies
Each ear is divided into three parts: the outer ear (auricle, auditory canal, and eardrum), the middle ear (ossicles, round and oval windows, and the Eustachian tube), and the inner ear (bony labyrinth). The nose is a mostly cartilaginous structure that warms, filters, and humidifies inhaled air, provides the sense of smell, and is the primary passageway for air to the lungs. Ludwig's angina is the spread of an existing dental infection or cellulitis into the three mandibular spaces.
Ear Emergencies
This causes swelling in the neck and submandibular tissue (which displaces the tongue superiorly), pain, trismus, muffled voice, dysphagia, drooling, fever or chills, and dyspnea. Priorities in the emergency department include maintaining the airway, breathing and circulation; relief of pain; and.

Safe Dosage Range
The dimensional analysis method uses factor labeling to calculate the dose of medication to be administered. The three factors used to calculate drug doses are the drug label factor, the conversion factor, and the drug order factor. The conversion factor allows you to build into the mathematical equation the conversions you need to calculate the correct dose of the drug.

Hypocalcemia is easily managed with intravenous calcium, but requires careful monitoring of calcium levels, heart rate, and blood pressure. Treatment of hypercalcemia depends on the cause, but usually includes intravenous hydration, diuretics, and possibly glucocorticoids. Hypermagnesemia can be treated with intravenous calcium chloride, diuresis with saline and furosemide, and possibly hemodialysis.

Lesson Notebook: Gastrointestinal Emergencies
The small intestine absorbs nutrients and other products of digestion and transports residue to the large intestine, which absorbs water and electrolytes and forms and stores stool.
Assessment
Specific Gastrointestinal Emergencies
Upper gastrointestinal bleeding can be spasmodic (usually due to portal hypertension) or variceal bleeding (usually due to erosion of the esophagus or duodenum). Other manifestations may include low body temperature, tachycardia, nausea, vomiting, flatulence, jaundice, and weight loss. Interventions may include administration of crystalloids, antiemetics, opioids, and antibiotics; insertion of a nasogastric tube; and monitoring vital signs and fluid intake and output.

Lesson Notebook: Gynecologic Emergencies
In the female reproductive system, the external genitalia include the mons pubis, the labia majora and minora, the clitoris, the vestibular glands, the hymen, the vaginal opening, the mouth of the urethra, and the ducts of Bartholin's and Skene's glands. If the egg is not fertilized, the endometrium sheds its inner lining during menstruation.
Specific Gynecologic Emergencies
Infection changes the amount, color and smell of the discharge and causes itching, burning or irritation. Pelvic inflammatory disease is an infection of the upper reproductive tract, usually as a result of an increasing sexually transmitted infection. The secondary phase produces a dull symmetrical rash on the palms and soles, fever, chills, lethargy, patchy alopecia, lymphadenopathy, loss of the lateral third of the eyebrows, and nonspecific findings.
Abnormal Vaginal Bleeding
Based on the patient population our emergency department typically serves, do we use any culturally specific interventions for women presenting with gynecologic emergencies.

Patient Teaching
Lesson Notebook: Head Trauma
Hematomas can occur in these areas because the middle meningeal artery is in the epidural space and the bridging veins span the subdural space. Watch for early signs of increased intracranial pressure, such as increasing headache or motor delays, behavioral changes, nausea, vomiting, speech or visual disturbances, and sluggish or ovoid pupils. Be alert for late signs of increased intracranial pressure, such as decreased responsiveness, impaired brainstem reflexes, decerebrate or decorticate posture, irregular respirations, fixed and dilated pupils, arrhythmias, and Cushing's triad (systolic hypertension, widening of pulse pressure, and bradycardia).
Specific Head Injuries
Primary brain injury occurs at the time of trauma, when the structure of the brain is damaged. Brain Trauma Foundation guidelines recommend intracranial pressure monitoring for all patients with a post-resuscitation Glasgow Coma Scale score of 8 or less and an abnormal computed tomography of the brain. Before discharging the patient, be sure to teach the patient and family key information, such as when to return to the emergency department and how to prevent brain injury.

Lesson Notebook: Hematologic and Oncologic Emergencies
Blood is a suspension of erythrocytes (red blood cells), leukocytes (white blood cells), platelets (thrombocytes) and other particles in an aqueous colloidal solution. There are six types of leukocytes in the blood: neutrophils, eosinophils, basophils, monocytes, lymphocytes and plasma cells. Also assess for changes in other systems, such as joint deformities or limited movement in the musculoskeletal system.
Hematologic Emergencies
Leukemia is a malignant disorder of the blood and blood-forming organs characterized by excessive, abnormal growth of leukocyte precursors in the bone marrow. Thrombocytopenia is an abnormally low platelet count that can be caused by sepsis, tumors, severe bleeding, and other causes. Specific treatments include oxygen; intravenous fluids; transfusion of fresh frozen plasma, packed red blood cells, cryoprecipitate and platelets.
Oncologic Emergencies
Depending on the type of hemophilia, treatment may require fresh frozen plasma, cryoprecipitate, and clotting factors. Treatment depends on the cause, but may include chemotherapy - or removal of vascular access and fibrinolytic and anticoagulant administration. Symptomatic spinal cord compression is an emergency because irreversible neurological damage can occur in hours.

Mechanical Ventilation
Invasive Monitoring
Sepsis
Minute ventilation The volume of air that moves in and out of the lungs in 1 minute. A therapy used in mechanical ventilation to ensure constant end-expiratory airway pressure and to increase the volume of gas in the lungs at the end of exhalation (residual functional capacity). Ideally, it increases the surface area of the alveoli to reduce the movement of blood through the lungs and improve gas exchange.
Cardiac Parameters
6 to 12 mm Hg Ventricular preload and volume at end diastole (used in fluid assessment) Systemic vascular. The resistance, impedance, or pressure that the right ventricle must overcome to eject the volume of blood in it.
