C) Increased heart rate
D) Decreased blood pressure
Rationale
Morphine is given to relieve pain and reduce myocardial oxygen demand. Pain relief is the primary
therapeutic response.
Q2
A patient is admitted with heart failure exacerbation. Which assessment finding requires
immediate intervention?
A) Bibasilar crackles
B) Weight gain of 2 pounds
C) Oxygen saturation 88% on room air CORRECT
D) Heart rate 92 beats/minute
Rationale
Oxygen saturation below 90% indicates hypoxemia and requires immediate oxygen therapy and further
assessment.
