1 What is the major reason for using a treatment to lower body temperature after cardiac arrest
to promote better neurological recovery?
a. Hypothermia decreases the metabolic rate by 7% for each decrease of 1° C.
b. Lower body temperatures are beneficial in patients with low blood pressure.
c. Temperatures of 40° C may reduce neurological impairment.
d. The lower body temperature leads to decreased oxygen delivery.
ANS: A
1. A patienthas been successfully converted from ventricular tachycardia with a pulse to a sinus
rhythm. Upon further assessment, it is noted that she is hypotensive. The appropriate treatment
for her hypotension may include:(Select all that apply.)
a. adenosine.
, b. dopamine infusion.
c. magnesium.
d. normal saline infusion.
e. sodium bicarbonate.
ANS: B, D
The QT interval is the total time taken for ventricular depolarization and repolarization.
Prolongation of the QT interval:
a. decreases the risk of lethal dysrhythmias.
b. usually occurs when heart rate increases.
c. increases the risk of lethal dysrhythmias.
d. can only be measured with irregular rhythms.
ANS: C
2The patient has an irregular heart rhythm. To determine an accurate heart rate, the nurse first:
a. identifies the markers on the ECG paper that indicate a 6-second strip.
b. counts the number of large boxes between two consecutive P waves.
,
, c. counts the number of small boxes between two consecutive QRS complexes.
d. divides the number of complexes in a 6-second strip by 10.
