Rad 1125 - Exam 2 Questions and Answers| New Update with 100% Correct Answers
-pnea Refers to breathing, respiration.
-thermo Refers to heat.
Hyper- Refers to over, above
Hypo- Refers to under, below
Define hyperthermia Abnormally high body temperature, especially that is induced for
therapeutic purposes. When a patient's body temperature increases above the normal body
temperature range.
identify the causes of hyperthermia Any event that increases cellular metabolism also
increases body temperature.
Define hypothermia Low body temperature. When a patient's body temperature falls below
the normal body temperature range.
identify the causes of hypothermia Can be caused by prolong exposure to cold
environmental temperatures, trauma to the hypothalamus, or medically induced.
Define tachypnea Abnormal rapidity of breathing. Used to describe an increase respiratory
rates greater than 20 breaths/min in an adult patient.
identify the causes of tachypnea Exercise, fever, anxiety, pain, infection, heart failure, chest
trauma, decreased oxygen in the blood, and central nervous system disease.
,Define bradypnea Abnormal slowness of breathing. Used to describe a decrease in the
respiratory rate.
identify the causes of bradypnea Results from the depression of the respiratory center of
the brain and is most common with drug overdoses, head trauma and hypothermia.
Define tachycardia Rapidity of the heart action, usually defined as a heart rate increase by
more than 20 beats per minute (BPM) in a resting adult or a heart rate greater than 100 BPM.
Refers to an increase in heart rate.
identify the causes of tachycardia Can be caused by an increase in cellular demands for
oxygen such as: exercise, fever, anemia, respiratory disorders, congestive heart failure,
hypoxemia, and shock. Can be caused by an increase in stimulus through the nervous system
such as: pain, anger, fear, anxiety, and medications.
Define bradycardia Refers to a decrease in heart rate. The slowness of the heartbeat as
evidenced by slowing of the pulse rate to less than 60 beats per minute (BPM).
identify the causes of bradycardia Unrelieved sever pain, subsequent heart problems, and
heart failure.
Define hypertension Persistently high arterial blood pressure. Usually identified as a blood
pressure that is persistently greater than 140/99 mm Hg.
-Hypertension is categorized into three different stages:
1. Prehypertension, 2. Stage 1 hypertension, and 3. Stage 2 hypertension.
identify the causes of hypertension Stress, medications, obesity, smoking, and various
disease states.
, Define hypotension Abnormally low blood pressure, seen in shock but not necessarily
indicative of shock. Usually identified as a blood pressure of less than 90/60 mm Hg.
- Hypotension is generally desirable as long as it does not produce symptoms
identify the causes of hypotension Can be caused by a patient in shock from severe
bleeding, burns, vomiting, diarrhea, trauma, or heat exhaustion that is caused by a decrease in
total blood volume.
Diaphoresis: Profuse sweating.
Febrile: Pertaining to or characterized by fever.
Ventilation: Mechanical movement of air into and out of the lungs.
Apnea: Not breathing.
Used to describe the absence of spontaneous ventilation.
Dyspnea: Used to describe difficult breathing.
Orthopnea Refers to difficulty breathing (dyspnea) unless sitting up or standing up.
Auscultation: Listening to the sounds of the body, typically through the use of a
stethoscope.
Apical pulses: Pulse rates obtained from placing a stethoscope over the heart and counting
each heartbeat to measure the pulse rate.
