Medical Terms Quiz

Epistaxis and Risks

• Severe epistaxis poses a risk of vomiting and aspiration, requiring careful monitoring during treatment.

Shock Definitions

• Hypoperfusion is synonymously referred to as shock, indicating a critical condition due to inadequate blood flow.

Blood Clotting and Medications

• Patients on blood thinners experience slower blood clotting, increasing risks during bleeding emergencies.

Pelvic Fracture Management

• In cases of open-book pelvic fractures, applying a compression device around the pelvis is vital due to potential internal bleeding.

Hematemesis

• The medical term for vomited blood is hematemesis, indicating serious underlying conditions.

Challenging Bleeding Control

• External bleeding control is most difficult with a femoral artery laceration, especially when blood pressure is stable.

Hypovolemic Shock

• Hypovolemic shock occurs when the body cannot cope with rapid blood loss, leading to critical impairment of circulation.

Wound Dressing Protocol

• If blood saturates a pressure dressing, additional dressings should be placed over the wound to manage bleeding effectively.

Blood Loss from Fractures

• A fractured femur can lead to the loss of over 1 liter of blood into thigh tissues.

SAMPLE History Importance

• During the SAMPLE history assessment, it is crucial to note if the patient is on blood-thinning medications, as this can impact treatment decisions.

Definition of Perfusion

• Perfusion is defined as the circulation of blood within an organ, crucial for meeting its metabolic needs.

Average Blood Volume

• An adult male weighing 80 kg has an approximate blood volume of 5.60 liters, which is essential for understanding hemorrhage impacts.

Nosebleeds and Head Trauma

• Bleeding from the nose following head trauma signals a possible skull fracture and should not be halted by pressure.

Controlling Bleeding

• For significant wrist lacerations, apply direct pressure to control bleeding, which is the first critical response.

Causes of Nasal and Oral Bleeding

• Possible causes for bleeding from the nose and mouth include skull fractures, high blood pressure, and sinus infections.

Tourniquet Application

• When using a stick and square knot as a tourniquet for severe bleeding, stop twisting the stick once bleeding ceases.

Blood Vessels as Containers

• Blood vessels are considered "containers" in the cardiovascular system, crucial for understanding blood flow management.

Blood Flow Tolerance

• The heart and brain cannot tolerate a lack of blood flow for more than a few minutes due to their high metabolic demands.

Patient Assessment in Transport

• If a patient with abdominal pain becomes diaphoretic and unresponsive, repeat the primary assessment to reassess their condition.

Transport for Abdominal Trauma

• For patients with significant abdominal bruising and rapid pulse from assault injuries, immediate transport is the most appropriate action.
