Zorluk: KolayPhysiological Adaptation

A practical nurse (PN) is collecting data on a client who had an ileostomy created three days ago. The client has had a high volume of liquid ostomy output over the past 12 hours. Which of the following clinical findings should the PN identify as early indicators of fluid volume deficit? Select all that apply.

  1. Heart rate of 118 beats/minuteCevap
  2. B
    Blood pressure of 154/88 mm Hg
  3. Dry, sticky oral mucous membranesCevap
  4. D
    Client report of mild incisional pain
  5. Dark amber, concentrated urineCevap
  6. F
    Capillary refill time of 2 seconds

Cevap

The correct indicators of fluid volume deficit are a heart rate of 118 beats/minute, dry, sticky oral mucous membranes, and dark amber, concentrated urine.
The correct options represent the body's direct physiological and compensatory responses to significant fluid loss. A heart rate of 118 beats/minute demonstrates the cardiovascular system's immediate attempt to maintain cardiac output. Dry mucous membranes reflect the systemic depletion of interstitial fluids. Dark, concentrated urine indicates that the kidneys are appropriately compensating by conserving water to prevent further volume loss.

Adım Adım Çözüm

1
Analyze the client's clinical risk factors based on the scenario.
The client has a new ileostomy with a high volume of liquid output over 12 hours, placing them at significant risk for hypovolemia (fluid volume deficit).
Identifying the primary risk factor guides the assessment toward recognizing signs of dehydration and circulatory compromise.
2
Evaluate each assessment finding against the expected physiological manifestations of fluid volume deficit.
Tachycardia, dry mucous membranes, and concentrated urine align with fluid loss. Hypertension, normal capillary refill, and localized pain do not indicate systemic fluid depletion.
The body compensates for fluid loss by increasing the heart rate, conserving water via the renal system, and shunting blood away from the periphery, while overall mucosal hydration visibly decreases.
