8. What is the influence of the nurse’s personal attitude toward pain?
a. Each person’s interpretation is influenced by background, such as how he or she

9. How does the nurse assess the following characteristics of pain? (p.1162)
a. Location.
i. “Where is your pain? Is it external or internal?” (Asking the patient with
acute pain to point to the painful area with one finger may help to localize
the pain. Patients with chronic pain may have difficulty trying to localize
their pain, however.)
b. Duration.
i. “How long have you been experiencing pain? How long does a pain
episode last? How often does a pain episode occur?”
c. Quantity (intensity).
i. Ask the patient to indicate the degree (amount) of pain currently
experienced on the following scale
d. Quality.
i. “What words would you use to describe your pain?
e. Chronology (pattern).
i. “How does the pain develop and progress?” (If pattern can be identified,
interventions early in a pain sequence will often be far more effective than
those used after the pain is well established.) “Has the pain changed since
it first began? If so, how?”
f. Aggravating factors.
i. “What makes the pain occur or increase in intensity?”
g. Alleviating factors.
i. “What makes the pain go away or lessen? What methods of relief have
you tried in the past? How long were they used? How effective were
they?” (Methods of relief currently in effect for hospitalized patients
should be apparent from the chart. It is important to verify the use of
current orders and their effectiveness with the patient. Outpatients may
need to be asked to record a medication profile, a thorough and accurate
account of all medications they are taking.)
h. Physiologic responses to pain.
