answer
Without fever
question
Febrile
answer
With fever
question
Apical pulse (aka "point of maximal impulse" or PMI)
answer
Central pulse; located at the apex of the heart (aka "point of maximal impulse" or PMI). Routinely used on infants - 3yrs. Helps determine discrepancies with radial pulse.
question
Peripheral pulse
answer
Pulse located away from the heart; wrist or foot.
question
Apical-radial pulse
answer
Normally apical & radial pulses are identical but an apical rate greater than the radial rate can indicate that the thrust of blood from the heart is too weak to be felt peripherally. Possible indication of vascular disease.
question
Apnea
answer
Absence of breathing
question
Arrhythmia (aka dysrhythmia)
answer
A pulse with an irregular rhythm (aka dysrhythmia).
question
Arterial blood pressure
answer
Measure of the pressure exerted by the blood as it flows through the arteries.
question
Arteriosclerosis
answer
Elastic & muscular tissues of the arteries are replaced with fibrous tissue, the arteries lose much of their ability to constrict & dilate. Common in middle aged & older adults.
question
Auscultatory gap
answer
Occurs particularly in hypertensive people; is the temporary disappearance of sounds normally heard over the brachial artery when the cuff pressure is high followed by the reappearance of the sounds at a lower level.
question
Basal metabolic rate (BMR)
answer
Rate of energy utilization in the body required to maintain essential activities such as breathing. Rates decrease with age. Generally younger people have higher BMR.
question
Body temperature
answer
Reflects the balance between the heat produced & lost from the body. Measured in degrees.

answer
Heart rate in an adult of less than 60 bpm.
question
Bradypnea
answer
Abnormally slow respirations.
question

answer
Volume of blood pumped into the arteries by the heart and equals the result of the stroke volume (SV) times the heart rate (HR) per min.
question
Compliance
answer
Arteries ability to contract & expand.
question
Conduction
answer
The transfer of heat from one molecule to a molecule of lower temperature. Cannot take place without contact between the molecules & normally accounts for minimal heat loss.
question
Constant fever
answer
Body temperature fluctuates minimally but always remains above normal.
question
Convection
answer
Dispersion of heat by air currents.
question

answer
Temperature of the deep tissues of the body such as the abdominal cavity & pelvic cavity. Remains relatively constant.
question
Costal breathing (aka thoracic breathing)
answer
Involves external interest all muscles and other accessory muscles such as the sternocleidomastoid muscles. Can be observed by the movement of the chest upward & outward.
question
Diaphragmatic breathing (aka abdominal breathing)
answer
Involves the contraction & relaxation of the diaphragm observed by the movement of the abdomen as a result of the diaphragms contraction & downward movement.
question
Diastolic pressure
answer
Pressure when the ventricles are at rest. The lower pressure present at all times within the arteries.
question
Dysrhythmia
answer
May consist of random irregular beats or a predictable pattern of irregular beats called "regularly irregular".
question
Evaporation
answer
Continuous vaporization of moisture from the respiratory tract and from the mucosa of the mouth & skin.
question
Exhalation (aka expiration)
answer
Breathing out or the movement of gases from the lungs to the atmosphere.
question
Fever (aka pyrexia or hyperthermia)
answer
A body temperature above the usual range.
question
Fever spike
answer
Temperature that that rises to a fever level rapidly following a normal temperature and then returns to normal within a few hours. Common to bacterial blood infections.
question
Heat balance
answer
When the amount of heat produced by the body equals the amount of heat lost.
question
Heat exhaustion
answer
Result of excessive heat & dehydration. Paleness, dizziness, nausea, vomiting, fainting, & moderately increased temperature of 101-102.
question
Heat stroke
answer
Persons generally have been exercising in hot weather, have warm flushed skin, and often do not sweat. Usually have a temperature of 106 or higher and may be delirious, unconscious, or having seizures.
question
Hematocrit
answer
When the proportion of red blood cells to the blood plasma is high. Highly viscous blood; thick.
question
Hyperpyrexia
answer
Very high fever. 105.8
question
Hypertension
answer
A blood pressure that is persistently above normal. When the diastolic pressure is 90 mmHg or higher or when the systolic is 140 mmHg or higher.
question
Hyperventilation
answer
Very deep rapid respirations.
question
Hypotension
answer
Blood pressure is below normal; systolic consistently between 85-110 mmHg in an adult whose normal pressure is higher than this.
question
Hypothermia
answer
Core body temperature below the lower limit of normal. 3 physiological mechanisms include; excessive heat loss, inadequate heat production to counteract heat loss, and impaired hypothalamic thermoregulations.
question
Hypoventilation
answer
Very shallow respirations.
question
Inhalation (aka inspiration)
answer
Intake of air into the lungs.
question
Insensible water loss
answer
Continuous & unnoticed water loss. (caused by evaporation)
question
Insensible heat loss
answer
Heat loss that accompanies the Insensible water loss. (caused by evaporation)
question
Intermittent fever
answer
Body temperature alternates at regular intervals between periods of fever and periods of normal or sub normal temperatures.
question
Korotkoffs sounds
answer
Five phases of sounds heard in a series when listening with a stethoscope while taking a blood pressure. 1- 1st faint clear tapping or thumping sounds are heard gradually becoming more intense. (systolic) 2- during cuff deflation when sounds have a muffled whooshing or swishing sound. 3- sounds become crisper & more intense but softer than in phase 1. 4- sounds become muffled & have a soft blowing quality. 5- level when the last sound is heard filled by silence (diastolic)
question
Orthostatic hypotension
answer
Blood pressure that falls when the client sits or stands. Usually the result of peripheral vasodialation in which blood leaves the central body organs, especially the brain, and moves to the periphery, often causing the person you feel faint. Causes: bleeding, several burns, & dehydration.
question
Oxygen saturation (SaO2)
answer
Arterial blood percentage of all the hemoglobin binding sites that are occupied by oxygen
question
Pulse
answer
A wave of blood created by contraction of the left ventricle of the heart. Generally the pulse wave represents the stroke volume (SV) output or amount of blood that enters the arteries with each ventricular contraction.
question
Pulse deficit
answer
Any discrepancy between two pulse rates. In no instance is the radial pulse greater than the apical pulse.
question
Pulse oximeter
answer
Noninvasive device that estimates a persons arterial blood oxygen saturation (SaO2) by means of a sensor attached to a finger, toe, nose, earlobe, or forehead.
question
Pulse pressure
answer
The difference between the diastolic and the systolic pressure.
question
Pulse rhythm
answer
The pattern of the beats and the intervals between the beats. Equal time lapses between beats of a normal pulse.
question
Pulse volume (aka pulse strength or amplitude)
answer
Refers to the force of blood with each beat. Can range from absent to bounding. Normal pulse can be felt with moderate pressure of the fingers and can be obliterated with greater pressure. Forceful or full blood volume that is obliterated only with difficulty is called full or bounding. A pulse that's easily obliterated with pressure from the fingertips is referred to as weak, feeble, or thready.
question
Radiation
answer
The transfer of heat from the surface of one object to the surface of another without contact between the two objects, mostly in the format of infrared rays.
question
Relapsing fever
answer
Short febrile periods of a few days are interspersed with periods of 1 or 2 days of normal temperature.
question
Remittent fever
answer
Wide range of temperature fluctuations of more than 2 degrees difference over a 24hrs period which are all above normal.
question
Respirations
answer
The actual of breathing.
question
Respiratory rhythm
answer
The regularity of the expirations & inspirations. Normally they're evenly spaced.
question
Respiratory quality (aka character)
answer
Refers to those aspects of breathing that are different from normal effortless breathing. The amount of effort and person must expert to breathe and the sound of the breathing.
question
Sphygmomanometer
answer
Indicates the pressure of the air within the cuff bladder. 2 types; aneriod & digital.
question
Surface temperature
answer
Temperature of the skin, subcutaneous tissue, and fat. Rises and falls in response to the environment.
