Zorluk: Çok zorPhysiological Adaptation

An 84-year-old resident in a long-term care facility has a history of mild vascular dementia and a recently placed indwelling urinary catheter. The resident's baseline blood pressure is 142/84 mm Hg, and their baseline heart rate is 72 beats/min. The practical nurse (PN) is called to the room and finds the resident pacing rapidly, speaking incoherently, and occasionally grimacing while clutching their lower abdomen. Current vital signs are: blood pressure 100/62 mm Hg, heart rate 114 beats/min, respiratory rate 26 breaths/min, and temperature 97.4°F (36.3°C). Which of the following is the priority action for the practical nurse (PN) to take?

  1. A
    Reassure and reorient the resident, attributing the incoherent speech to a progression of the underlying vascular dementia.
  2. B
    Document the vital signs and continue monitoring, as the current blood pressure reading remains within a generally acceptable range for an older adult.
  3. Apply supplemental oxygen, ensure the resident's safety, and immediately escalate the findings to the supervising registered nurse.Cevap
  4. D
    Administer the prescribed as-needed analgesic for suspected bladder spasms and reassess the client's grimacing.

Cevap

The correct priority action is to apply supplemental oxygen, ensure the resident's safety, and immediately escalate the findings to the supervising registered nurse.
The correct action recognizes that this older adult is demonstrating signs of atypical urosepsis leading to distributive shock. Older adults often do not mount a febrile response to infection; instead, they present with hypothermia, acute confusion (delirium), and tachypnea. The significant drop in blood pressure from the resident's baseline, combined with compensatory tachycardia and tachypnea, indicates a life-threatening physiological collapse. Applying oxygen supports the client's ABCs, and immediate escalation to the registered nurse is required because the client needs rapid advanced interventions, such as intravenous fluids and antibiotics.

Adım Adım Çözüm

1
Analyze the resident's baseline data compared to current data.
The resident has a significant drop in blood pressure (142/84 to 100/62 mm Hg), new-onset tachycardia (114 beats/min), tachypnea (26 breaths/min), hypothermia, and acute cognitive changes.
Identifying deviations from baseline is critical for recognizing acute physiological deterioration, especially in older adults.
2
Correlate the clinical findings with the client's risk factors.
The resident has a new indwelling urinary catheter, placing them at high risk for a catheter-associated urinary tract infection (CAUTI) progressing to urosepsis.
Older adults often present with atypical signs of infection, such as hypothermia (97.4°F) and acute confusion, rather than a classic fever.
3
Prioritize nursing actions based on the ABCs (Airway, Breathing, Circulation) and scope of practice.
The priority is to address the compromised airway/breathing (tachypnea) with oxygen and immediately escalate to the RN to manage the suspected distributive (septic) shock.
The PN must recognize impending shock and initiate life-saving protocols while rapidly notifying the RN for advanced interventions.

Anahtar Kavram

Older adults frequently exhibit atypical manifestations of systemic infection (sepsis), such as acute confusion, hypothermia, and tachypnea, without presenting a fever. A significant drop from baseline blood pressure indicates impending shock and requires immediate ABC interventions and escalation.
