Difficulty: MediumPhysiological Adaptation

A nurse evaluates a client with a history of hepatic cirrhosis who is being monitored for a suspected gastrointestinal bleed. The client is alert but frequently shifts positions in bed and appears restless. The current vital signs are: blood pressure 114/86114/86 mm Hg (admission baseline 134/74134/74 mm Hg), heart rate 112112 beats/min, and respiratory rate 2222 breaths/min. The client repeatedly complains of severe thirst. Which action should the nurse take first?

  1. Initiate continuous pulse oximetry and establish large-bore intravenous access.Answer
  2. B
    Administer a prescribed as-needed sedative to alleviate the client's restlessness.
  3. C
    Provide a small amount of ice chips to relieve the client's complaint of severe thirst.
  4. D
    Document the findings and plan to reassess the client's vital signs in one hour.

Answer

Initiate continuous pulse oximetry and establish large-bore intravenous access.
The client is exhibiting early compensatory signs of hypovolemic shock secondary to a suspected gastrointestinal bleed. These indicators include a narrowing pulse pressure (a drop from a baseline of 6060 mm Hg down to 2828 mm Hg), tachycardia, mild tachypnea, severe thirst, and restlessness (an early sign of cerebral hypoxia). The priority nursing action according to the ABC (Airway, Breathing, Circulation) framework is to secure oxygenation monitoring and establish large-bore intravenous access to prepare for rapid fluid and blood product administration.

Step-by-Step Solution

1
Analyze the client's current clinical presentation compared to baseline.
The client has a narrowing pulse pressure (decreased from 6060 mm Hg to 2828 mm Hg), tachycardia (112112 beats/min), tachypnea (2222 breaths/min), restlessness, and severe thirst.
Identifying trends in vital signs and recognizing new symptoms is critical for detecting physiological deterioration.
2
Correlate the findings with the client's risk factors.
The client has a history of cirrhosis and suspected gastrointestinal bleeding, making hypovolemia/hemorrhage the most likely cause of these symptoms.
Understanding the underlying pathology provides context for the compensatory mechanisms being observed.
3
Determine the priority nursing intervention based on ABCs (Airway, Breathing, Circulation).
The most urgent need is to manage potential hypoxia and impending circulatory collapse by preparing for aggressive fluid and blood product resuscitation.
Prioritization frameworks dictate that physiological stability and perfusion take precedence over comfort, routine reassessment, or symptom-masking.

Key Concept

Early indicators of hypovolemic shock include a narrowing pulse pressure, tachycardia, and altered mental status (restlessness), requiring immediate circulatory support.
