Difficulty: HardPhysiological Adaptation

An unlicensed assistive personnel (UAP) urgently calls the practical nurse (PN) to the room of an 81-year-old client who underwent a total knee arthroplasty the previous day. The UAP reports the client has become suddenly agitated, is speaking incoherently, and is trying to remove their intravenous (IV) line. The client was previously alert and oriented. Current vital signs are a heart rate of 112 bpm, blood pressure of 98/62 mm Hg, and a respiratory rate of 26 breaths/min. Which action is the priority for the PN to take?

  1. A
    Initiate reality orientation and dim the lights in the client's room.
  2. B
    Prepare to administer a prescribed as-needed intramuscular analgesic.
  3. Obtain an oxygen saturation reading using a pulse oximeter.Answer
  4. D
    Re-secure the intravenous tubing to prevent accidental dislodgment.

Answer

Obtain an oxygen saturation reading using a pulse oximeter.
Sudden restlessness, agitation, and confusion in an older adult client, especially postoperatively, are cardinal early signs of hypoxia. Combined with borderline tachycardia (112 bpm) and tachypnea (26 breaths/min), the clinical picture strongly suggests an acute respiratory or hemodynamic compromise. According to the ABC (Airway, Breathing, Circulation) prioritization framework, the nurse must first assess the client's oxygenation status before implementing other interventions.

Step-by-Step Solution

1
Analyze the clinical cues in the scenario.
The client is experiencing a sudden onset of agitation, confusion, tachycardia (112 bpm), and tachypnea (26 breaths/min).
Recognizing a sudden change from baseline is critical for identifying acute physiological decompensation.
2
Apply the Airway, Breathing, Circulation (ABC) prioritization framework.
The symptoms strongly suggest a Breathing or oxygenation issue (hypoxia) as the root cause of the acute confusion.
Hypoxia often manifests early as restlessness and altered mental status, especially in older adults.
3
Select the intervention that addresses the highest priority physiological need.
Assessing oxygen saturation provides immediate objective data regarding the client's respiratory status.
Data on oxygenation is required to confirm hypoxia and guide further emergent interventions before addressing secondary issues.
