Correct Answers
Temperature Range for adult - Correct Answer 96.8-100.4 degrees F
Pulse Range for adult - Correct Answer 60-100 bpm
Respiration range for adult - Correct Answer 12-20 breaths/min
Blood Pressure Range for adult - Correct Answer 120/80
O2 Saturation - Correct Answer >= 95%
When to Measure vital signs - Correct Answer on admission
routine schedule based on facility policy or HCP order
change in pt condition
before and after: admin of meds that affect respiratory, cardiovascular or temperature-control
function and physical activity as appropriate
before,during, and after: surgery or invasive dx procedures and blood product transfusions
Hypothalamus decreases temperature by - Correct Answer vasodilation, sweating, and inhibition of
heat production
Hypothalamus increases temperature by - Correct Answer vasoconstriction, muscle contraction, and
shivering
Heat production - Correct Answer metabolism, physical exertion, hormones, and shivering
heat loss - Correct Answer evaporation, convection, conduction, and radiation
90% of heat loss comes from - Correct Answer the skin
, Factors affecting body temperature - Correct Answer age, exercise, hormone level, circadian rhythm,
stress, environment, temperature alterations
Oral temp safety alert - Correct Answer if patient ate, drank, chewed gum, or smoked, wait 15-30
minutes
Rectal temp safety alert - Correct Answer lubricate the thermometer; avoid in patients with heart
disease or heart surgery; may stimulate vagus nerve, causing bradycardia; do not perform on
patients with rectal disease or those who have had rectal surgery
Tympanic temp safety alert - Correct Answer do not perform on patients who have drainage from the
ear
Axillary temp safety alert - Correct Answer axilla must be dry to obtain accurate reading
HR x Stroke Volume = - Correct Answer Cardiac Output (5000 mL/min)
Factors that increase pulse - Correct Answer hemorrhage
activity
fever (increase 10 bpm per 1 degree above normal)
pain
emotions
Factors that decrease pulse - Correct Answer elderly
endurance athletes
beta blockers
calcium channel blockers
hypothermia
Carotid pulse safety alert - Correct Answer lightly palpate one side at a time to prevent diminished
O2 to the brain
