Difficulty: HardPhysiological Adaptation

While monitoring a 74-year-old client 12 hours after a total knee arthroplasty, the practical nurse notes several changes in the client's status. The client's baseline vital signs were blood pressure 138/82 mm Hg, heart rate 72 bpm, and respiratory rate 16 breaths/min. Currently, the blood pressure is 112/68 mm Hg, heart rate is 96 bpm, and respiratory rate is 22 breaths/min. Additionally, the client is exhibiting mild new-onset confusion and the indwelling urinary catheter has drained 45 mL over the past two hours. Which action should the practical nurse take first?

  1. Report these comprehensive findings to the registered nurse immediately.Answer
  2. B
    Document the vital signs in the electronic health record as they remain within normal limits.
  3. C
    Explain to the client that mild confusion is an expected effect of anesthesia in older adults.
  4. D
    Administer the prescribed PRN analgesic assuming the vital sign changes are related to postoperative pain.

Answer

Report these comprehensive findings to the registered nurse immediately.
The client is exhibiting subtle but critical signs of compensatory shock, including a downward trend in blood pressure, an upward trend in heart and respiratory rates, decreased urine output (less than 30 mL/hr), and altered mental status. In the practical nurse scope of practice, recognizing these systemic signs of acute decompensation requires immediate escalation to the registered nurse for comprehensive assessment and provider notification.

Step-by-Step Solution

1
Analyze the trend in the client's vital signs compared to their baseline.
The blood pressure is decreasing, while the heart rate and respiratory rate are increasing.
Identifying trends is more critical than looking at isolated numbers to detect early physiological decline.
2
Evaluate the additional clinical data provided in the scenario.
The client has new-onset confusion and a urine output of only 45 mL over two hours (22.5 mL/hr, which is less than the required minimum of 30 mL/hr).
Oliguria and altered mental status are classic signs of decreased organ perfusion.
3
Synthesize the findings to determine the priority nursing action.
The combination of borderline vital sign changes, decreased urine output, and confusion indicates compensatory shock, requiring immediate escalation.
Within the scope of practice, the practical nurse must recognize acute decompensation and immediately inform the registered nurse to facilitate rapid medical intervention.
