Patient Care and Trauma Flashcards

A patient is in the anatomic position when he or she is:

Answer: standing facing you with arms at the sides and the palms of the hands facing outward.

The anatomic position is a standard reference point used in anatomy and medicine to describe the location of body parts consistently. It is defined as a person standing erect, facing forward, with arms at the sides, and the palms of the hands facing forward (outward). This consistent reference helps avoid ambiguity when describing anatomical relationships.

The term "anterior" refers to the:

Answer: front

In anatomical terminology, 'anterior' refers to the front of the body or toward the front of a structure. For example, the sternum is anterior to the spine. This term is essential for precisely describing the locations and relationships of various body parts.

Which of the following statements is correct?

Answer: The wrist is distal to the elbow.

The term 'distal' means farther away from the point of attachment or the trunk of the body. The wrist is indeed farther from the trunk than the elbow, making the statement 'The wrist is distal to the elbow' correct. Conversely, 'proximal' means closer to the point of attachment.

A fracture of a femur in a location farthest away from the hip is:

Answer: distal

The term 'distal' refers to a position farther away from the point of attachment or the trunk of the body. The hip is the point of attachment of the femur to the trunk. Therefore, a fracture in the femur that is farthest away from the hip would be described as a distal fracture of the femur.

The location of a lateral body part is:

Answer: away from the midline of the body.

In anatomical terminology, 'lateral' means away from the midline of the body. The midline is an imaginary line that divides the body into equal left and right halves. For example, the arms are lateral to the chest, meaning they are positioned further from the body's central axis.

A 40-year-old woman has an injury to the mid-shaft humerus following a motor vehicle crash. What major joint is immediately distal to her injury?

Answer: Elbow

The humerus is the bone of the upper arm. The term 'mid-shaft' refers to the middle portion of this bone. The elbow joint is located at the distal (further away from the body's core) end of the humerus, connecting it to the bones of the forearm (radius and ulna). Therefore, the elbow is the major joint immediately distal to an injury in the mid-shaft humerus.

The circulatory system is responsible for:

Answer: pumping blood through the body.

The circulatory system, also known as the cardiovascular system, is primarily responsible for the continuous movement of blood throughout the body. The heart acts as the pump, propelling blood through a network of vessels. This pumping action ensures that oxygen, nutrients, hormones, and waste products are efficiently transported to and from all cells and tissues.

All of the following are components of the scene size-up, except:

Answer: determining whether the patient is sick or injured.

Scene size-up is the initial assessment of an emergency scene, focusing on safety, resources, and the overall nature of the incident. Its components include ensuring scene safety, identifying the mechanism of injury (MOI) or nature of illness (NOI), and determining the need for additional resources. Determining whether the patient is sick or injured is part of the primary assessment, which follows the scene size-up, not a component of the scene size-up itself.

As you approach an emergency scene, you should first:

Answer: scan the area to determine the extent of the incident.

Upon approaching an emergency scene, the very first action an EMR should take is to perform a visual scan of the entire area. This initial scan helps to quickly identify potential hazards, determine the overall scope of the incident, and estimate the number of patients. This crucial step ensures responder safety and helps in formulating an initial plan before direct patient contact.

Scene hazards that are not visible to emergency responders include:

Answer: poisonous fumes

Scene hazards can be both visible and invisible. While spilled gasoline, ice on the road, and unstable surfaces are readily apparent, poisonous fumes often lack color or odor, making them undetectable by sight or smell. These invisible hazards pose a significant threat to responders and patients, necessitating careful assessment and protective measures.

The purpose of noting the mechanism of injury (MOI) is to:

Answer: allow you to predict what injuries the patient may have.

The mechanism of injury (MOI) refers to the forces that caused a traumatic injury. By understanding the MOI, such as a fall from a height or a high-speed collision, EMRs can anticipate potential injury patterns and the severity of those injuries. This predictive capability helps guide the assessment and treatment process, allowing responders to look for specific injuries commonly associated with certain types of trauma.
