Difficulty: HardPhysiological Adaptation

An older adult client is admitted to the medical-surgical unit after three days of severe vomiting and diarrhea. While collecting data, which of the following findings strongly indicate to the practical nurse that the client is experiencing an acute physiological deterioration requiring immediate escalation of care? Select all that apply.

  1. Blood pressure decreases from an admission baseline of 138/82 mm Hg to 104/66 mm Hg.Answer
  2. The client becomes suddenly disoriented to time and place during the assessment.Answer
  3. The resting apical heart rate is 114 beats per minute with a thready quality.Answer
  4. D
    The client reports diffuse abdominal cramping rated as a 5 on a 0 to 10 pain scale.
  5. E
    Capillary refill time is brisk and evaluated at less than 2 seconds.
  6. F
    The client experiences a large episode of watery diarrhea during the shift.

Answer

The correct findings are the decrease in blood pressure, the sudden disorientation, and the tachycardic, thready pulse.
The correct findings represent hallmark early signs of hypovolemic shock due to severe fluid volume deficit. A significant downward trend in blood pressure, compensatory tachycardia with a weak pulse, and sudden altered mental status (indicating decreased cerebral perfusion) are acute, life-threatening changes that require immediate rapid intervention.

Step-by-Step Solution

1
Analyze the client's admitting diagnosis (severe diarrhea and vomiting) to identify the primary physiological risk.
The client is at extremely high risk for fluid volume deficit progressing to hypovolemic shock.
Prolonged gastrointestinal fluid loss significantly decreases circulating blood volume.
2
Evaluate each assessment finding to differentiate between expected baseline symptoms and acute, life-threatening complications.
Abdominal cramping and diarrhea are expected. Normal capillary refill is reassuring. The dropping blood pressure, tachycardia, and confusion are unexpected acute changes.
Safe prioritization requires identifying new, unstable, or systemic changes over localized, expected symptoms.
3
Identify the specific findings that indicate compromised Airway, Breathing, or Circulation (ABCs).
The dropping blood pressure, compensatory tachycardia (114 beats/min), and sudden disorientation indicate poor systemic and cerebral perfusion.
These are early hallmark signs of impending hypovolemic shock requiring immediate escalation to the registered nurse.

Key Concept
