Patient Care Theory Flashcards
What is tachypnea
Increased Resp rate
What is hypotension
Low blood pressure
What is hypertension
High blood pressure
What is bradypnea
Decreased resp rate
What is bradycardia
Decreased Heart rate
What is tachycardia
Increased Heart rate
What is perfusion
How blood moves around the body
What does adventitious mean
No abnormal sounds in breathing
The signs and symptoms are severity of a pulmonary embolus vary and are related primarily to:
The size of the embolus
What is the most common cause of pneumothorax
Penetration from a rib fracture
A pneumothorax is best described as:
Air in the pleural space
The portion of the heart layer/s that directly cover the heart surface is called the:
Visceral pericardium and Serous pericardium
True or false: The coronary sinus carries oxygenated blood to the left atrium, which in turn delivers that blood to the left ventricle to be transported to rest of body.
False because The coronary sinus is a vein that collects deoxygenated blood from the heart muscle (myocardium). It delivers this deoxygenated blood to the right atrium, not the left atrium.
What will ARDs cause
Pulmonary edema will result
Your EMCA-P has been cleared, patient is conscious. what is you next course of action?
Manual cervical immobilization of the pt.
Sternal fractures are frequently associated with what?
Myocardial injury
If the male had highented resp rates it can further be described as:
Tachypneic
If the patient has high blood pressure it can fall into the category of:
Hypotensive
Perfusion is best described as:
Refers to the process of circulating blood through the pulmonary capillary bed
True or false: A tension pneumothorax is always an exacerbation of a simple pneumothorax.
False because A tension pneumothorax occurs when air enters the pleural space but cannot escape (a one-way valve mechanism). This leads to progressive accumulation of air, causing severe pressure on the lungs, heart, and great vessels, resulting in significant respiratory distress and hemodynamic instability.
True or false: O2 stimulates the respiratory centre in the brainstem
False, in a health human CO2 will stimulate the brainstem
True or false: With a tension pneumothorax we may see tracheal deviation away from the unaffected side
False, you will see tracheal deviation towards the affected side.
All veins:
Carry blood back to the heart
The heart muscle is perfused with blood by the _____, which branch off the aorta.
Coronary arteries
The heart is the circulatory pump of the body. The right side of the heart pumps_______ blood through the ______ circulation.
Oxygen poor/Pulmonary
Which of the following signs and symptoms have specificity to a simple pneumothorax?
Tachycardia and SOB
The open pneumothorax should be cared for using which techniques.
Cover the wound with an occlusive dressing, taped on three sides or an ACS
Which is the most common cause of upper airway obstruction
The tongue
The contraction of the ventricles facilitates opening of the:
Aortic and pulmonic valves
Which are the smallest divines of the HIS bundles
Purkinje fibers
Which of the following structures are located within the mediastinal cavity
Trachea
Which vessel carries blood from the heart to the systemic circulation
Aorta
Cardiac electrical impulse conduction is normally initiated in which structure
Sinoatrial node
Ventricular ejection per each heartbeat is best defined as:
Stroke volume
Blood pressure is equal to which
Heart rate x stroke volume x peripheral vascular resistance
Which valve separates the right ventricle from the lungs
Pulmonic
The arteries that branch off the aortic arch are the:
carotid and subclavian arteries and Brachiocephalic arteries
The coronary artery that supplies/ feeds the SA node is
Right coronary artery
True or false: Pt. who suffer a pericardial tamponade demonstrate initial peripheral vasodilation
False
True or false: Becks triad is best identified by: muffled heart sounds, JVD, hypertension.
False because Beck’s triad is best identified by muffled heart sounds, jugular venous distension (JVD), and hypotension
True or false: As oxygenated blood enters the right side of the heart it travels to the lungs via the pulmonary arteries.
Oxygenated blood does not enter the right side of the heart. Instead, it enters the left side of the heart via the pulmonary veins after being oxygenated in the lungs. The right side of the heart handles deoxygenated blood.
Cardiogenic shock is:
caused by extensive myocardial damage
An object composed of clotted blood, fat and / or plaque that breaks loose from the wall of an artery and travels the circulatory system is called:
An embolism
The process of ventilation, diffusion and perfusion allows gas exchange to occur efficiently in the lungs and other tissue. The derangement in pulmonary embolisms is principally of:
perfusion
Hypoxia is best defined as:
Inadequate oxygen at the cellular level
If the pt. has a high heart rate it can be described as:
Tachycardic
Which patient situations represents a life threat identified in the initial assessment of an adult?
Stridor is audible
Functional residual capacity:
Is expiratory reserve plus residual volume
Patients who suffer from chronic bronchitis are often referred to as:
Blue bloaters
What is considered a intrinsic risk factory for respiratory disease?
Genetic predisposition and stress
