Hormones increase cell metabolism; Directly affects liver & muscle cells
How does fever influence body heat?
Increased temperature results in increased cell metabolism rate
How does thermal regulation influence body heat?
Hypothalmus controls the body core temperature; Vasoconstriction, shivering, and release of epinephrine occurs when the body senses cold (This results in increased heat production and cell metabolism).
How does age influence body heat?
Newborn/infants are greatly influenced by temperature & need pretection from cold. Children & Elders-Sensitive to environmental temperature changes and are at risk for hypothermia. Elders have inadequate diet, loss of SQ fat, lack of activity, and reduced thermoregulatory control.

Women body temp increases by 0.3-0.6 degree C (0.5-1.0 degree F) during ovulation due to increased progesterone production.
How does stress influence body heat?
sympathetic nervous system (SNS) can increase the production of epinephrine/norepinephrine, thereby increasing metabolic activity and heat production (i.e icreased temp w/anxious client).
How does the environment influence body heat?
Extremes heat w/out modification causes an increased body temp.
What is normal pulse oximetry?

a reliable measurement.
What is the advantage(s) of taking an axillary temp?
safe and noninvasive.
What is the advantage(s) of taking a tympanic temp?
readily accesible, very fast and it reflects the core temperature.
What is the disadvantage(s) of taking a temp rally?
Glass thermometers can break if bitten, it is inaccurate if client had just ingested hot or cold food or fluid or smoked and it could injure the mouth following oral surgery.
What is the disadvantage(s) of taking a temp rectally?
Inconvenient and more unpleasent for clients; difficult for slient who cannot turn to the side; could injure the rectum following rectal surgery. A rectal glass thermometer does not respond to changes in arterial temps as quickly as an oral themometer, a fact that may be potentially dangerous for febrile clients because misleading information may be acquired. Presence of stool may interfere with thermometer placement. If the stool is soft, the thermometer may be embedded in stool rather than against the wall of the rectum.
What is the disadvantage(s) of taking an axillary temp?
The thermometer must be left in place a long time to obtain an accurate measurement.
What is the disadvantage(s) of taking a tympanic temp?
Can be uncomfortable and involves risk of injuring the membrane if the probe is inserted too far. & Repeated measurements may vary. Right and left measurements can differ. Presence of cerumen can affect the reading.
What is the correct technique for taking a pulse rate?
1) Explain to the client what & why. Discuss results. 2) Wash hands. 3) Provide for client privacy. 4) Select the pulse point. Normally-radial pulse; unless circulation to another area needs assessed 5) comfortable resting position for client. 6) Palpate and count the pulse 7) Assess the pulse rhythm and volume.
What pulses can you assess for pulse rate?
brachial, radial, temporal, carotid, femoral, popliteal, posterior tibial, and pedal
What do you do if the radial pulse is not accessible?
Use another pulse site. Temporal, apical
Where is the location of an apical pulse?
Apical, at the apex of the heart.adult-left side of the chest, 8 cm (3 in.) left of the sternum (breastbone) & the fourth, fifth, or sixth intercostals space. 7-9 y.o. apical pulse is located at the fourth or fifth intercostals spaces. < 4 yrs-left of the MCL; 4-6 yrs, at the MCL
What is the significance of taking an apical-radial pulse?
may need to be assessed for clients with certain cardiovascular disorders. Normally, rates are identical. abnormal indicates blood thrust is too feeble to be felt at the peripheral pulse site, can indicate vascular disease is preventing transmission.
What do you do if the apical-radial pulse difference is abnormal?
Promptly report the discrepency to a physician.
What is a pulse deficit?
A discrepancy between the apical and radial pulse rates. In no instance is the radial pulse greater than the apical pulse.

first sound is systolic-pressure (pressure of blood from contraction of heart ventricle); second sound is diastolic-pressure (pressure when the heart ventricles are at rest)
Who is prone to developing a decreased for elevated or elevated BP?
Age-BP increases with age, Exercise-Increases BP (*Wait 20-30 minutes after exercise for BP), Stress, Race-increased in African Americans, Gender, Medications-Antihypertensives decrease BP; Cardiac meds decrease BP; Some meds can increase BP (dopamine), Diurnal Variations-Lowest in morning, Obesity-Increases especially in children, Disease process-Cardiac; Vascular; Conditions affecting blood volume; blood viscosity; Decreased cardiac output (shock i.e absence of O2 to the body systems); Hormonal (Adrenal alterations i.e. epinephrine, norepinephrine)

Describe the factors that affect the vital signs & accurate measurement of them.
Age: older people and infants are greatly influenced by temperature. People over 75 years are at the risk of hyperthermia (below 96.8 or 36o) for a vary reasons like inadequate diet loss of subcutaneous fat lack of activity etc. Diurnal variations (circardian rhythms) temperature change through out the day. It is high in the morning and Afternoon and low at sleeping time (4-6Am). Exercise: hard work or exercise increases the temperature.
Describe other factors that affect the vital signs & accurate measurement of them.
Hormones: women have a more fluctuations than men in there temperature due to hormones change. Secretion of hormones increases the temp. Environment: if the room temperature is high the body temperature will be high and vice versa.
Measurement of vital signs: pulse, respiration, B/P,
PULSE: a wave of blood created by contraction of the left vertical of the heart RESPIRATION: act of breathing Blood PRESURE: the pressure excreted by the blood as it flows

Heat production: basal metabolic rate (BMR) rate of energy utilize in the body required to maintain esstentional activities such as breathing .BMR is decrease with the age. Thyroxin output: stimulation of heat production in the body increase through the metabolism. Hormones: increase rate of cellular metabolism. Fever: increase in cellular metabolic rate increase the body temperature.

Exercise: pulse are high due to activity, but athletes is less often than a normal person because of greater cardiac size and strength & efficiency Medication: medications make the low pulse or it may be high Hypovolemia: loss of blood cause the high pulse rate and high B/P. Stress: sympathetic nervous stimulate high pulse; over activity of the heart. Position change: sitting or standing pools the blood flow low and lower the pulse Pathology: certain disease can cause lower pulse.. Impair the oxygen

The client had a removal of the axilla or hip or lymph nodes. The client has a infusion in the limb
Methods of the assessing the B/P
Direct: (invasive monitoring) measurements involves the insertion of the of a catheter in to the brachial or radial or femoral artery. Two invasive indirect methods of B/P anscultatory:is most common method used in the hospitals ,a sphygmonometer a cuff and a stethoscope . it is most accurate way of assessing the B/P.
KOROTKOFF’S Sound
Phase 1: A SHARP TAPPING the pressure level is first faint, clear tapping or thumping sounds that heard. Phase 2 A SWISHING WHOOSHING SOUND the period during deflation when the sounds have a muffled whooshing or swishing quality Phase 3: A THUMP SOFTER THAN A TAPPING the period during the blood flows freely through an increasingly open artery, & sound become more crisper and intense. Phase 4: A SOFTER BLOWING the time when sounds become modified and have a soft , blowing quality. Phase 5: the pressure level when the sound is heard and is follow by a silence.
WHAT ARE THE FACTORS THAT AFFECT THE BLOOD PRESSURE?
Age, Exercise, Stress, Race, gender, medications, Diurnal variations, diseases process.
Factors that affect 02 saturations

Circulation: the oximeter will not return accurate reading if the area under the sensor has impaired circulation.
