Obtaining a Medical History
• Medical history: previous medical
conditions and events for patient.
• Signs: something you can see and
observe about patient.
– Can be pale skin; rapid pulse; open wound
to chest.
– All are obvious.

Obtaining a Medical History
• Interviewing Your Patient
– An alert patient is the best source of
information.
– Chief complaint: main medical complaint
described by patient.
– Family members, bystanders, first
responders should all be questioned.
– ALOC- altered level of consciousness
– LOC- level of consciousness

Think About It
• You become suddenly ill and a medical
provider begins asking you personal
medical history questions. What would
make you more likely to be honest and
forthright with answers?
• How could you apply this answer to
your own assessment practices?

Vital Signs
• Pupils
– Note general condition; identify any
obvious injury or deformity.
– Ensure both pupils are round and same
size.
– Respond to sudden introduction of light
– Pupils constrict in the light; dilate in the
dark
– Light affects the pupil size

Think About It
• Could vital signs ever be considered
unreliable?
• What does “treat the patient; not the
device” mean and why is this especially
important to remember when working
with automated or electronic vital sign
equipment?

Summary
• Good patient assessment: gathering
information (history) about patient and
chief complaint and obtaining complete
and accurate vital signs.
• Properly introduce yourself and get
patient's name right away.
• Whenever possible, direct your
questions to patient.

Summary
• Speak clearly and confirm that patient
hears, understands, and answers each
question before asking another.
• Utilize SAMPLE tool to help guide
questions, and always document
patient's answers.
• Obtain set of vital signs to establish
good baseline.

previous readings to establish trends in
patient's condition.
• Most vital signs have multiple
characteristics; document
characteristics for each vital sign.

through assessing respirations, pulse,
blood pressure, skin signs, and pupils?
8. How do the techniques used to assess
a pulse in an infant, child, and adult
patient differ?
9. How do normal and abnormal vital
sign values differ for the infant, child,
and adult patient?

vital signs from every other student in
class.
• Discuss challenges and results.
