What is a common clinical feature of Intestinal obstruction?

Appeared in: NORCET 2 - 2021 (shift-1)

Explanation

Vomiting is one of the four cardinal signs of intestinal obstruction (along with pain, distension, and constipation).
When the obstruction is in the small intestine, distal to the ampulla of Vater where bile enters the duodenum, the vomitus becomes bile-stained (bilious).
In high (proximal) small bowel obstruction, bilious vomiting occurs early and is a prominent feature.
This symptom reflects the inability of gastrointestinal contents to pass the point of blockage, leading to retrograde movement and emesis.

Option B: Diarrhea is not a common feature of intestinal obstruction. The hallmark sign is the cessation of passing stool and flatus, known as absolute constipation or obstipation.
Option C: Fever is not a typical initial sign of a simple intestinal obstruction. It is considered a warning sign of a serious complication.
Option D: This option is incorrect because diarrhea and fever are not common clinical features of an uncomplicated intestinal obstruction.

Clinical Relevance

Nursing practice connection: Knowing Clinical Manifestations of Intestinal Obstruction helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Recognizing the cardinal signs of intestinal obstruction, including the character of the vomitus, is crucial for early diagnosis and intervention to prevent life-threatening complications.
Nurses play a key role in managing patients with suspected obstruction by maintaining NPO status, inserting and managing nasogastric tubes for decompression, administering IV fluids, and closely monitoring for signs of deterioration.
Patient safety is paramount. The development of fever, tachycardia, or severe, constant pain in a patient with an obstruction requires immediate escalation to the physician, as it may signal bowel strangulation, a surgical emergency.

How to Approach the Question

First, identify the core concept of the question, which is the 'common' clinical features of intestinal obstruction.
Recall the four cardinal signs of intestinal obstruction: colicky abdominal pain, vomiting, abdominal distension, and absolute constipation.
Evaluate each option based on these cardinal signs.
Analyze 'Bilious vomiting'. Vomiting is a cardinal sign, and its bilious nature points to a small bowel location, which is a very common site for obstruction. This is a strong possibility.
Analyze 'Diarrhea'. This is the opposite of constipation, which is a cardinal sign. Therefore, diarrhea is an unlikely common feature.
Analyze 'Fever'. Fever is not one of the four cardinal signs and typically indicates a complication. It is not a common initial feature.
