53
How many vertebrae in Coccyx
30-33
54
Where is the greater trochanter located in the body?
Greater Trochanter is located proximal to the femoral head and neck on the lateral side of the femur.
55
Hypoxic Drive
The body’s backup system. When oxygen levels fall this system will stimulate breathing. There are areas in the brain, the walls of the aorta, and the carotid arteries that act as oxygen sensors. These sensors are satisfied by minimal levels of oxygen in the arterial blood. Less sensitive and less powerful than carbon dioxide sensors in the brainstem.
56
How is cardiac output calculated
CO=HR x SV Ex: 70 beats/min x 75 mL/beat = 5,250 mL/min or 5.25 L/min.
57
Which Arteries do not carry oxygenated blood
Pulmonary Arteries
58
Major Arteries and where they're located
Aorta (main artery leaving the back left side of the heart, carries freshly oxygenated blood to the body) Pulmonary Artery (right side of the heart, and carries oxygen-depleted blood to the lungs) Arterioles (smallest branch of an artery leading to capillaries
59
Carotid Artery
Central Pulse Upper portion of the neck
60
Femoral Artery
Central Pulse In the groin
61
Radial Artery
Peripheral Pulse At the wrist, and at the base of the thumb
62
Brachial Artery
Peripheral Pulse On the medial aspect of the arm, elbow, and shoulder
63
Posterior Tibial Artery
Peripheral Pulse, Posterior to the medial malleolus
64
Dorsalis Pedis Artery
Peripheral Pulse On the top of the foot
65
How much blood do children have
2-3L
66
How much blood do infants have?
300mL
67
Which organs are considered retroperitoneal organs and why are they called that?
They lie behind the posterior sheath of the peritoneum and include the aorta, esophagus, second and third parts of the duodenum, ascending and descending colon, pancreas, kidneys, ureters, and adrenal glands.
68
Be familiar with the differences between an infant’s upper airway and that of an adult.
A​ child's cricoid cartilage is harder and stronger. An infant's number of alveoli is relatively low, and so is there oxygen. The Infant tongue is larger in proportion to the size of the oral cavity, and the airway is proportionally shorter and narrower.)
69
Be familiar with the “Special Populations” box on page 262.
When you interview adolescents in the presence of their family, they may withhold certain information or even lie to protect their privacy or image. For this reason, you should attempt to ask more sensitive questions privately, where adolescents feel they can answer without constraint.
70
Common factors that would affect an older patient's vital signs
Cardiac function declines with age, due in large part to atherosclerosis. Because the vascular system of older adults becomes stiff, blood vessels are unable to dilate and contract as effectively as a result diastolic blood pressure increases. The airway increases in size. Breathing is more laborious because alveoli has less surface area. Structures protecting the upper airway decrease in function. Cough and gag reflexes diminish along with the ability to clear secretions. They’re at greater risk for aspiration and airway obstruction. Glucose and metabolism slows. Medications, overall health, medical conditions
71
Define atherosclerosis
A condition characterized by the buildup of cholesterol and calcium along the inner walls of blood vessels, resulting in the formation of plaque.
72
What is the effect of the vascular system of the older adult becoming stiff?
Blood vessels are unable to dilate and contract as effectively.
73
The increase of risk of bleeding the the skull is most directly related t
atrophy or shrinkage of the brain creates space between the brain and dura mater (subdural space)
74
What is the first key rule of lifting a patient?
Always keep your back in a straight upright (vertical) position, and lift without twisting. Always face the patient and point your feet in the same direction. Spread your legs shoulder width apart.
75
What is the safest and most powerful method for lifting a patient?
Power Lift
76
guidelines for carrying a patient on a stretcher?
1. Estimate the weight of both the patient and the associated equipment to be lifted and gauge the limitations of your team's abilities. 2. Coordinate your movement with those of the other team members while constantly communication with them 3. Do not twist your body as you are carrying the patient. 4. Keep the weight that you are carrying as close to your body as possible while keeping your back in a locked-in position. 5. Do not bend at the waist; this could hyperextend your back. Instead, flex at the hips, and bend at the knees.
77
The stretcher should be pushed from the____ end
head
78
When carrying a patient down stairs, always keep the _____elevated
head
79
What situations should the rapid extrication technique be used?
The vehicle or scene is unsafe Explosives or other hazardous materials are on the scene There is a fire or danger of fire The patient cannot be properly assessed before being removed from the vehicle The patient has a life-threatening condition The patient blocks your access to another seriously injured patient.
80
What is the first step of performing the rapid extrication technique?
The first provider applies the manual in-line support of the patient head and cervical spine from behind or side.
81
working interdependently as part of a true team
Each provider is assigned to a particular area or task, all of the providers in an interdependent group work together with shared responsibilities, accountability, and a common goal. Opposed to focusing on the goals of the respective areas.
82
What could be the consequence of a BLS worker performing a skill outside of their level of certification?
You risk liability
