A 26-year-old female medical student presents to the student health clinic reporting a two-day history of frequent, watery bowel movements. She notes having four to five loose stools daily, accompanied by mild, diffuse abdominal cramping. She has not noticed any visible blood or mucus in the toilet. The patient denies any recent international travel, new medications, or known exposure to sick individuals. Her only regular medication is a daily oral contraceptive. Her temperature is 37.1°C (98.8°F), blood pressure is 116/74 mm Hg, and pulse is 80/min. Abdominal examination reveals a soft, non-distended abdomen with hyperactive bowel sounds. There is mild, generalized tenderness to deep palpation, but no guarding, rigidity, or rebound tenderness.

Which of the following is the most appropriate next step in management for this patient?

  1. Recommend oral rehydration therapy and supportive careCevap
  2. B
    Prescribe a 5-day course of oral ciprofloxacin
  3. C
    Order an upright abdominal radiograph to evaluate for small bowel obstruction
  4. D
    Obtain an arterial blood gas to calculate expected respiratory compensation
  5. E
    Notify the public health department of a confirmed reportable infectious outbreak

Cevap

Recommend oral rehydration therapy and supportive care
The correct approach is oral rehydration therapy and supportive care. This patient presents with acute, uncomplicated watery diarrhea without any red flag symptoms (such as high fever, bloody stools, severe abdominal pain, or signs of volume depletion). In such cases, the etiology is most often viral and the condition is self-limiting. The mainstay of treatment is maintaining adequate hydration with oral rehydration solutions. Pharmacological interventions or extensive diagnostic workups are not indicated for mild, acute gastroenteritis in an otherwise healthy adult.

Adım Adım Çözüm

1
Evaluate the patient's clinical presentation and vital signs.
The patient has acute, non-bloody diarrhea with normal vital signs and no warning signs (e.g., high fever, severe dehydration).
To determine the severity of the illness and rule out indications for aggressive intervention or extensive diagnostic workup.
2
Formulate a differential diagnosis based on the benign clinical picture.
The most likely diagnosis is self-limiting acute viral gastroenteritis or a mild foodborne illness.
Most cases of acute watery diarrhea in young, otherwise healthy patients are viral and resolve spontaneously.
3
Select the most appropriate initial management step.
Oral rehydration therapy and supportive care are indicated.
Uncomplicated acute diarrhea requires only fluid and electrolyte replacement while the illness runs its natural course.

Anahtar Kavram
