Question 5 of 5
Which assessment finding in a patient admitted with acute decompensated heart failure (ADHF) requires the most immediate action by the nurse?
Correct Answer: A
Rationale: A decrease in O2 saturation to less than 92% indicates hypoxemia, and the nurse should start supplemental O2 immediately. An increase in apical pulse rate, 1-kg weight gain, and decreases in urine output also indicate worsening heart failure and require nursing actions, but the low O2 saturation rate requires the most immediate nursing action.
