NURS_2140 Exam 3: Burns and Shock Questions With
Complete Solutions
___% of patients who smoke, will light themselves on fire
Correct Answers 83
A 198-lb patient is to receive a dobutamine infusion at 5
mcg/kg/min. The label on the
infusion bag states: dobutamine 250 mg in 250 mL of normal
saline. When setting the
infusion pump, the nurse will set the infusion rate at how many
milliliters per hour? Correct Answers 27
To administer the dobutamine at the prescribed rate of 5
mcg/kg/min from a concentration of
250 mg in 250 mL, the nurse will need to infuse 27 mL/hr.
A 78-kg patient with septic shock has a pulse rate of 120
beats/min with low central venous
pressure and pulmonary artery wedge pressure. Urine output has
been 30 mL/hr for the past 3
hours. Which order by the health care provider should the nurse
question?
a. Administer furosemide (Lasix) 40 mg IV.
b. Increase normal saline infusion to 250 mL/hr.
c. Give hydrocortisone (Solu-Cortef) 100 mg IV.
d. Titrate norepinephrine to keep systolic blood pressure (BP)
above 90 mm Hg Correct Answers a
furosemide will lower the filling pressures and renal perfusion
further for the patient with septic shock; patients with septic
shock require large amounts of fluid replacement
,A nurse is assessing a patient who is receiving a nitroprusside
infusion to treat cardiogenic shock. Which finding indicates that
the drug is effective?
a. No new heart murmurs
b. Decreased troponin level
c. Warm, pink, and dry skin
d. Blood pressure of 92/40 mm Hg Correct Answers c
warm, pink, and dry skin indicates that perfusion to tissues is
improved. Because nitroprusside Is a vasodilator, the blood
pressure may be low even if the drug is effective
A nurse is caring for a patient who has burns of the ears, head,
neck, and right arm and hand. The nurse should place the patient
in which position?
a. Place the right arm and hand flexed in a position of comfort.
b. Elevate the right arm and hand on pillows and extend the
fingers.
c. Assist the patient to a supine position with a small pillow
under the head.
d. Position the patient in a side-lying position with rolled towel
under the neck. Correct Answers b
the right hand and arm should be elevate to reduce swelling and
the fingers extended to avoid flexion contractures (even though
this position may not be comfortable for the patient). The patient
with burns of the ears should not use a pillow for the head
because this will put pressure on the ears, and the pillow may
stick to the ears.
A nurse is caring for a patient whose hemodynamic monitoring
indicates a blood pressure of
, 92/54 mm Hg, a pulse of 64 beats/min, and an elevated
pulmonary artery wedge pressure
(PAWP). Which intervention ordered by the health care provider
should the nurse question?
a. Elevate head of bed to 30 degrees.
b. Infuse normal saline at 250 mL/hr.
c. Hold nitroprusside if systolic BP is less than 90 mm Hg.
d. Titrate dobutamine to keep systolic BP is greater than 90 mm
Hg. Correct Answers b
The patient's elevated PAWP indicates volume excess in relation
to cardiac pumping ability,
consistent with cardiogenic shock. A saline infusion at 250
mL/hr will exacerbate the volume
excess. The other actions will help to improve cardiac output,
which should lower the PAWP and may raise the BP.
A patient arrives in the emergency department with facial and
chest burns caused by a house
fire. Which action should the nurse take first?
a. Auscultate the patient's lung sounds.
b. Determine the extent and depth of the burns.
c. Give the prescribed hydromorphone (Dilaudid).
d. Infuse the prescribed lactated Ringer's solution. Correct
Answers a
a patient with facial and chest burns is at risk for inhalation
injury and assessment of airway and breathing is the priority.
The other actions will be completed after airway management is
assured.
A patient has just arrived in the emergency department after an
electrical burn from exposure
