Question

Difficulty: Very hardPhysiological Adaptation

During the morning shift on a trauma step-down unit, the practical nurse assumes care for a client who sustained a closed pelvic fracture two days prior. The unlicensed assistive personnel reports that the client has suddenly become combative and is trying to get out of bed. Upon evaluation, the nurse notes the client is tachypneic at 28 breaths per minute, has a heart rate of 115 beats per minute, and displays pinpoint reddish-purple spots across the axillary region. Which action must the practical nurse prioritize?

  1. Initiate oxygen therapy, position the client upright, and urgently alert the registered nurse.Answer
  2. B
    Implement fall precautions, dim the room lights, and attempt to reorient the client to the current time and place.
  3. C
    Auscultate bilateral lung fields and assess the client's pupillary responses to light.
  4. D
    Record the findings in the electronic health record and schedule a vital sign reassessment in 15 minutes.

Answer

The correct action is to initiate oxygen therapy, position the client upright, and urgently alert the registered nurse.
The correct answer immediately addresses the physiological threat of hypoxia caused by a suspected fat embolism. Upright positioning and oxygen therapy stabilize the client's respiratory status while the registered nurse is promptly alerted to coordinate advanced, intensive care.

Step-by-Step Solution

1
Analyze the clinical cues presented in the scenario.
The client has a recent pelvic fracture, sudden combativeness, tachypnea, tachycardia, and axillary petechiae.
Identifying abnormal data points is the first step in recognizing acute physiological deterioration.
2
Correlate the symptoms with potential complications.
The triad of respiratory distress, neurological compromise, and a petechial rash 48 hours after a pelvic fracture strongly indicates fat embolism syndrome (FES).
FES is a life-threatening systemic complication that requires immediate recognition.
3
Determine the physiological priority using the ABC (Airway, Breathing, Circulation) framework.
The tachypnea and hypoxia-induced combativeness indicate an immediate threat to breathing and systemic oxygenation.
Prioritization frameworks dictate that acute respiratory compromise must be addressed before secondary assessments or environmental modifications.
4
Select the intervention that best aligns with the practical nurse's scope of practice.
Applying oxygen, positioning for optimal lung expansion, and immediately escalating to the registered nurse is required.
The PN must stabilize the client using basic supportive measures while securing advanced RN or provider intervention.
