Difficulty: HardReduction of Risk Potential

During a routine assessment on the surgical unit, a nurse evaluates a client who underwent an open splenectomy earlier in the day. The client's spouse reports that the client has suddenly become restless and anxious. A review of the electronic health record reveals the following vital sign trends:

TimeBlood PressureHeart RateRespiratory RatePulse Oximetry
14:00134/72 mm Hg82 beats/min14 breaths/min99% on room air
15:00126/78 mm Hg94 beats/min18 breaths/min97% on room air
16:00112/86 mm Hg118 beats/min24 breaths/min94% on room air

The client's urine output for the past hour is 15 mL. Based on these findings, which action is the priority to prevent further physiological deterioration?

  1. Initiate a rapid infusion of isotonic crystalloid fluids and notify the surgical provider immediately.Answer
  2. B
    Elevate the head of the bed to 90 degrees to optimize diaphragmatic excursion and oxygenation.
  3. C
    Administer a prescribed intravenous anxiolytic to calm the client and decrease myocardial oxygen demand.
  4. D
    Assess the patency of the indwelling urinary catheter and perform a bladder scan to check for retention.

Answer

The priority action is to initiate a rapid infusion of isotonic crystalloid fluids and immediately notify the surgical provider, as the client is exhibiting signs of early hemorrhagic shock.
The client is exhibiting classic signs of early compensatory hemorrhagic shock, including a narrowing pulse pressure (from 62 to 26 mm Hg), tachycardia, tachypnea, oliguria, and restlessness (cerebral hypoxia). Because the client had a highly vascular organ removed (splenectomy), internal bleeding is a high-risk complication. The immediate priority is to restore intravascular volume and tissue perfusion by administering isotonic crystalloids and notifying the surgeon for potential surgical re-exploration.

Step-by-Step Solution

1
Analyze the vital sign trends over the past two hours.
The pulse pressure has narrowed significantly (from 62 mm Hg to 26 mm Hg), accompanied by tachycardia (82 to 118 beats/min) and tachypnea (14 to 24 breaths/min).
Identifying subtle changes in vital signs is crucial for detecting early physiological deterioration.
2
Correlate vital signs with clinical symptoms and surgical history.
The narrowed pulse pressure, tachycardia, oliguria (15 mL/hr), and new-onset restlessness following a highly vascular surgery (splenectomy) indicate compensatory hemorrhagic shock.
Internal bleeding is a major postoperative risk; the body compensates by vasoconstricting (raising diastolic BP) and increasing heart rate to maintain cardiac output.
3
Determine the priority nursing intervention based on the ABCs (Airway, Breathing, Circulation).
The primary threat to life is circulatory collapse from hypovolemia.
Restoring intravascular volume with isotonic fluids is the immediate life-saving intervention before surgical correction of the hemorrhage.
4
Evaluate and eliminate the alternative interventions.
Elevating the head of the bed or administering sedatives are contraindicated and could precipitate cardiovascular collapse.
High-Fowler's position decreases venous return, and sedatives mask critical signs of cerebral hypoxia while potentially causing vasodilation.

Key Concept

Early recognition of postoperative hypovolemic (hemorrhagic) shock through subtle indicators such as a narrowing pulse pressure, tachycardia, and altered mental status.
