Multiple choice

In the management of a patient with a suspected perforated viscus, which of the following is a primary consideration?

  1. Antibiotic therapy

  2. Nasogastric tube placement

  3. Fluid resuscitation

  4. Exploratory laparotomy
Reveal answer Fill a bubble to check yourself
D Correct answer

Multiple choice

In the management of a patient with a suspected appendiceal abscess, which of the following is typically recommended?

  1. Antibiotic therapy alone

  2. Percutaneous drainage

  3. Immediate appendectomy

  4. Exploratory laparotomy
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Percutaneous drainage is often the initial treatment of choice for appendiceal abscess, allowing for脓液drainage and resolution of infection prior to definitive surgical management.
