Quiz 4 (Chapters 6 & 7) Flashcards
Inadequate circulation of blood throughout the body is known as:
Shock
The ring-shaped structure that forms the lower portion of the larynx is the:
cricoid cartilage.
The cardiac muscle receives its supply of oxygenated blood by which of the following mechanisms?
Coronary arteries that branch off the aorta
What are the two most easily injured portions of the spine?
Cervical and lumbar
You respond to a patient who is choking on a foreign object. This would indicate that the problem is most likely in the ________ airway.
upper
The fluid component of the blood is called:
plasma
What type of shock may be caused by hemorrhage or dehydration?
Hypovolemic shock
Which of the following respiratory processes requires the active use of muscles?
inhalation
Certain blood vessels that contain specialized sensors that detect the level of internal pressure and transmit messages to the nervous system, which then triggers the smooth muscle in the vessel walls to make any needed size adjustments. These sensors are called:
stretch receptors.
The seat of respiratory control is found in the:
mendulla oblongata
Hypersensitivity can occur in response to:
certain foods, drugs, or animals.
What is the correct order of air flow from the nose to the alveoli in the lungs?
Nose, nasopharynx, hypopharynx, larynx, trachea, bronchi, alveoli
Which of the following statements provides reasons for the disruption of respiratory control?
Stroke, infection, brain trauma, toxins and drugs, and neurologic disorders can interrupt this control.
The trachea is:
below the larynx.
Which of the following are the components of the complete nervous system?
Brain, spinal cord, and nerve tissue
Which organ secretes insulin after a person eats a large meal?
Pancreas
Physiology is the study of:
body function.
________ blood returns to the right side of the heart.
Deoxygenated
An exaggerated response by the immune system to a particular substance is called:
hypersensitivity.
What is the determining factor for cardiac output?
Heart rate multiplied by stroke volume
You have been dispatched to a local shopping mall where a 63-year-old female patient has slipped and fallen in a department store. Upon your arrival, you find her supine on the ground, conscious and oriented with stable vital signs, complaining of severe pain in the upper portion of her left leg and hip. Her left leg is slightly shortened and rotated outward. The bone most commonly fractured with a “broken hip” is the:
femur
The pressure against the walls of the blood vessels as blood is ejected from the heart and circulates through the body is the ________ blood pressure.
systolic
Which of the following glands secrete epinephrine into the bloodstream?
Adrenal
Our blood transports oxygen from the lungs to the cells and returns with what byproduct of metabolism?
Carbon dioxide
The MOST superficial, or outermost, layer of the skin is the:
epidermis
Which of the following is most likely to lead to dehydration?
vomiting
What is the name of the large thigh bone?
femur
Endocrine disorders generally involve too many or not enough:
hormones.
Your patient is an 84-year-old male with difficulty breathing and peripheral edema. He tells you he has been suffering for many years with “heart failure,” and his condition is worsening, especially with trouble breathing at night. Your knowledge of cardiovascular physiology suggests that his condition could have resulted from the failure of either the right or left side of his heart. Which chamber of the heart is the strongest, most muscular part of the heart and is primarily responsible for pumping oxygenated blood to the rest of the body?
Left ventricle
Bile is created in which organ of the digestive system?
Liver
What type of shock may not allow the heart rate to increase to compensate for hypoperfusion?
Cardiogenic
Which of the following is the primary function of the stomach?
Chemical breakdown of food by acidic secretions
The tube through which urine passes to be eliminated from the body is the:
urethra
What causes the “seesaw” breathing pattern of young children?
They rely more on the diaphragm during breathing difficulty.
The musculoskeletal system protects the internal organs, gives the body shape, and:
provides for body movement.
The only movable part of the skull is the:
mandible
Which of the following causes inhalation?
The intercostal muscles and the diaphragm contract.
The basic function of the pulmonary system that is known as ventilation involves:
the movement of gases to and from the alveoli.
Not all inspired air reaches the alveoli; 150 mL is stopped in the airway leading to the alveoli. This is called:
dead air space.
The basic nutrient of the cell and the building block for energy is:
glucose.
Anemia is a decrease in the number of:
red blood cells.
Which type of muscle allows for movement such as running or throwing a baseball?
Voluntary muscle
You are caring for a 47-year-old male patient with classical chest pain suggestive of a myocardial infarction. Based on your understanding of the cardiovascular system, you know he could be suffering from damage, narrowing, or blockage of what arteries?
Coronary arteries
The volume of air that is breathed in and out with each breath is called the:
tidal volume
What is the term for the cellular function of converting glucose into energy (ATP)?
Metabolism
The net result of respiratory challenges is low oxygen, also called ________, within the body
hypoxia
Which of the following terms describes the heart muscle’s ability to generate its own electrical impulses?
Automaticity
Your patient is a 22-year-old female who accidentally ate some shellfish and is now having a severe reaction. She tells you that the last time she ate shellfish, “They had to put a breathing tube in my throat and I almost died.” Her face is starting to swell up and you can hear audible wheezing when she breathes. The chemical that produces edema and narrowing of the airways during hypersensitivity reactions like this is called:
histamine
Which organ is the principal organ of the renal system?
kidney
What two components are directly related to aerobic metabolism?
Oxygen and glucose
