RNSG 1105 Exam 3 Complete Questions
With 100% Correct Answers.
Temperature Range for adult - Correct answer96.8-100.4 degrees F
Pulse Range for adult - Correct answer60-100 bpm
Respiration range for adult - Correct answer12-20 breaths/min
Blood Pressure Range for adult - Correct answer120/80
O2 Saturation - Correct answer>= 95%
When to Measure vital signs - Correct answeron 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 answervasodilation,
sweating, and inhibition of heat production
Hypothalamus increases temperature by - Correct answervasoconstriction,
muscle contraction, and shivering
Heat production - Correct answermetabolism, physical exertion, hormones, and
shivering
heat loss - Correct answerevaporation, convection, conduction, and radiation
90% of heat loss comes from - Correct answerthe skin
Factors affecting body temperature - Correct answerage, exercise, hormone
level, circadian rhythm, stress, environment, temperature alterations
, Oral temp safety alert - Correct answerif patient ate, drank, chewed gum, or
smoked, wait 15-30 minutes
Rectal temp safety alert - Correct answerlubricate 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 answerdo not perform on patients who
have drainage from the ear
Axillary temp safety alert - Correct answeraxilla must be dry to obtain accurate
reading
HR x Stroke Volume = - Correct answerCardiac Output (5000 mL/min)
Factors that increase pulse - Correct answerhemorrhage
activity
fever (increase 10 bpm per 1 degree above normal)
pain
emotions
Factors that decrease pulse - Correct answerelderly
endurance athletes
beta blockers
calcium channel blockers
hypothermia
Carotid pulse safety alert - Correct answerlightly palpate one side at a time to
prevent diminished O2 to the brain
Assessment sites for pulse - Correct answertemporal, carotid, apical, brachial,
radial, femoral, popliteal, posterior tibial, dorsalis pedis
Doppler ultrasound - Correct answerused when pulses are difficult to palpate or
auscultate; produces high-frequency sound waves
Characteristics of pulse - Correct answerrate, rhythm, strength, equality
Most important factor in ventilation - Correct answerchange in CO2
