Post Quiz
What is the most common cause of small bowel obstruction?
Adhesions
Rationale: Most bowel obstructions occur in the small intestine. Adhesions are the most common
cause of small bowel obstruction, followed by hernias and neoplasms. Volvulus (twisting of the bowel)
is another cause, but is not the most common.
A patient with abdominal distention experiences reflux vomiting, which the nurse knows can lead to
which of the following acid-base disturbances?
Metabolic alkalosis
Rationale: Reflux vomiting results in the loss of hydrogen ions and potassium from the stomach,
leading to reduction of the serum electrolytes chloride and potassium in the blood and causing
metabolic alkalosis.
The initial symptom of abdominal pain described by the patient in which of the following ways would
%
lead the nurse to suspect a small bowel obstruction?
Colicky, crampy
Rationale: The initial symptom is usually crampy pain that is wavelike and colicky due to persistent
peristalsis both above and below the blockage.
The nurse is aware that untreated small bowel obstruction can progress to which type of shock?
Hypovolemic
Rationale: The vomiting that accompanies small bowel obstruction can lead to acute fluid losses,
which can lead to hypovolemic shock. Hypovolemia can occur from the fluid shifts related to the
edema and congestion occurring in the bowel.
