,Chapter 1. Perfusion
MULTIPLE CHOICE
1. The nurse is explaining to a student nurse about impaired central perfusion. The nurse
knows the student understands this problem when the student states, Central perfusion
a. is monitored only by the physician.
b. involves the entire body.
c. is decreased with hypertension.
d. is toxic to the cardiac system.
ANS: B
Central perfusion does involve the entire body as all organs are supplied with oxygen and
vital nutrients. The physician does not control the bodys ability for perfusion. Central
perfusion is not decreased with hypertension. Central perfusion is not toxic to the cardiac
system.
2. A patients serum electrolytes are being monitored. The nurse notices that the
potassium level is low. The nurse knows that the patient should be observed for
a. tissue ischemia.
b. brain malformations.
c. intestinal blockage.
d. cardiac dysthymia.
ANS: D
Cardiac dysthymia is a possibility when serum potassium is high or low. Tissue ischemia,
brain malformations, or intestinal blockage do not have a direct correlation to potassium
irregularities.
,3. The nurse is conducting a patient assessment. The patient tells the nurse that he has
smoked two packs of cigarettes per day for 27 years. The nurse may find which data upon
assessment?
a. Blood pressure above the normal range
b. Bounding pedal pulses
c. Night blindness
d. Reflux disease
ANS: A
Smokers have a constriction of the blood vessels due to the tar and nicotine in cigarettes. This
constriction may lead to hypertension. Bounding pulses, night blindness, and reflux disease
do not have a direct link to smoking
4. A nurse is explaining to a student nurse about perfusion. The nurse knows the student
understands the concept of perfusion when the student states, Perfusion
a. is a normal function of the body, and I dont have to be concerned about it.
b. is monitored by the physician, and I just follow orders.
c. is monitored by vital signs and capillary refill.
d. varies as a person ages, so I would expect changes in the body.
ANS: C
The best method to monitor perfusion is to monitor vital signs and capillary refill. This allows
the nurse to know if perfusion is adequate to maintain vital organs. The nurse does have to be
concerned about perfusion. Perfusion is not only monitored by the physician but the nurse
too.
Perfusion does not always change as the person ages.
5. A patient was diagnosed with hypertension. The patient asks the nurse how this
disease could have happened to them. The nurses best response is Hypertension
, a. happens to everyone sooner or later. Dont be concerned about it.
b. can happen from eating a poor diet, so change what you are eating.
c. can happen from arterial changes that impede the blood flow.
d. happens when people do not exercise, so you should walk every day.
ANS: C
Hardening of the arteries from atherosclerosis can cause hypertension in the patient.
Hypertension does not happen to everyone. Changing the patients diet and exercising may be
a positive life change, but these answers do not explain to the patient how the disease could
have happened.
6. The patient is brought to the emergency department after a motor vehicle accident.
The patient is diagnosed with internal bleeding. The nurses primary concern is to monitor for
a. mental alertness.
b. perfusion.
c. pain.
d. reaction to medications.
ANS: B
Perfusion is the correct answer, because with internal bleeding, the nurse should monitor vital
signs to be sure perfusion is happening. Mental alertness, pain, and medication reactions are
important but not the primary concern.
7. The patient asks the nurse to explain the sinoatrial node in the heart. The nurses best
response would be, The sinoatrial node
