Zorluk: KolayPhysiological Adaptation

A practical nurse (PN) is collecting data on a client who is receiving rapid intravenous (IV) fluid therapy for severe dehydration. Which of the following findings should alert the PN that the client is developing fluid volume overload? Select all that apply.

  1. New onset of fine crackles auscultated in the bilateral lung basesCevap
  2. Jugular venous distention visible when the head of the bed is elevatedCevap
  3. Increased respiratory rate of 28 breaths/min with shortness of breathCevap
  4. D
    Heart rate decreasing from 116 to 82 beats/min
  5. E
    Client report of mild discomfort at the IV insertion site without swelling

Cevap

The correct findings indicating fluid volume overload are new onset of fine crackles in the lung bases, jugular venous distention, and an increased respiratory rate with shortness of breath.
Fluid volume overload occurs when intravenous fluids are administered faster than the cardiovascular and renal systems can process them. This excess volume backs up into the pulmonary circulation (causing crackles, tachypnea, and shortness of breath) and the systemic circulation (causing jugular venous distention). Recognizing these acute Airway, Breathing, and Circulation (ABC) cues is critical for immediate PN escalation.

Adım Adım Çözüm

1
Analyze the client's current treatment and risk factors.
The client is receiving rapid IV fluids, placing them at high risk for circulatory overload if the body cannot process the volume quickly enough.
Identifying the intervention (rapid fluids) directly points to the potential complication (fluid volume excess).
2
Evaluate each finding for signs of excess fluid in the pulmonary or systemic circulation.
Crackles, rapid breathing, and jugular venous distention all demonstrate fluid backing up into the lungs and venous system.
These are the classic physiological adaptations indicating that the heart cannot pump the sudden excess volume effectively.
3
Differentiate between signs of improvement and signs of deterioration.
A normalizing heart rate (82 beats/min) is a sign of improvement from dehydration, and minor IV site pain is a local issue, neither of which indicates overload.
Recognizing expected therapeutic responses prevents the unnecessary escalation of normal findings.
