Question

Difficulty: MediumPhysiological Adaptation

Following a percutaneous liver biopsy, a client remains on bed rest for post-procedure monitoring. Which specific clinical findings should immediately alert the nurse that this client is developing early hemorrhagic shock? Select all that apply.

  1. New-onset restlessness and vague anxietyAnswer
  2. Apical pulse increase from 78 to 116 beats per minuteAnswer
  3. Blood pressure shift from 132/74 mmHg to 124/88 mmHgAnswer
  4. D
    Capillary refill time of 2 seconds in the nail beds
  5. E
    Warm, dry skin over the distal extremities
  6. F
    Respiratory rate of 14 breaths per minute

Answer

The findings indicating early hemorrhagic shock are new-onset restlessness, an increased apical pulse rate, and a narrowing pulse pressure.
In the early (compensatory) stage of hemorrhagic shock, decreased intravascular volume triggers the sympathetic nervous system. This physiological adaptation attempts to maintain cardiac output and tissue oxygenation, resulting in tachycardia (increased heart rate) and peripheral vasoconstriction. Vasoconstriction raises the diastolic blood pressure, leading to a narrowed pulse pressure. Additionally, subtle changes in cerebral perfusion present as early restlessness, anxiety, or mild confusion.

Step-by-Step Solution

1
Analyze the clinical scenario.
The client has undergone a liver biopsy, involving a highly vascular organ, placing them at significant risk for internal bleeding (hypovolemic/hemorrhagic shock).
Identifying the primary complication risk sets the context for interpreting vital signs.
2
Recall the physiological adaptation in early (compensatory) hemorrhagic shock.
The sympathetic nervous system activates to preserve perfusion to vital organs by increasing heart rate, increasing respiratory rate, and causing peripheral vasoconstriction.
Understanding the body's compensatory mechanisms explains the specific symptom presentation.
3
Evaluate each option against these compensatory mechanisms.
Restlessness reflects early cerebral hypoxia. Heart rate increases (tachycardia) to boost cardiac output. Blood pressure demonstrates a narrowed pulse pressure due to vasoconstriction raising diastolic pressure.
Matching clinical data to the pathophysiology accurately identifies the correct early indicators.
4
Eliminate normal findings and contradictory symptoms.
A capillary refill of 2 seconds, warm skin, and a normal respiratory rate of 14 are all normal or opposite to the expected signs of shock (prolonged refill, cool/clammy skin, tachypnea).
Differentiating abnormal shock manifestations from baseline normal findings eliminates distractors.
