A nurse is assessing a client who has lactose intolerance. Which of the following will the nurse recognize as clinical findings associated with lactose intolerance? Select all that apply:
A.
abdominal distention
B.
visible peristalsis
C.
hypoactive bowel sounds
D.
occasional diarrhea
E.
flatus
The correct answer and Explanation is :
For a client with lactose intolerance, the clinical findings you would recognize include:
A. Abdominal distention
D. Occasional diarrhea
E. Flatus
Explanation
Lactose intolerance occurs when the body lacks enough lactase, the enzyme needed to digest lactose, a sugar found in milk and dairy products. This leads to various gastrointestinal symptoms when lactose is consumed.
- Abdominal Distention: This happens due to the accumulation of gas and fluids in the intestines. When lactose is not properly digested, it ferments in the colon, producing gas and causing the intestines to expand.
- Occasional Diarrhea: Lactose that is not absorbed in the small intestine reaches the colon, where it is fermented by bacteria. This fermentation process produces acids and gases, leading to water being drawn into the colon, resulting in diarrhea.
- Flatus: Gas is produced as a byproduct of lactose fermentation. This can lead to increased flatulence, which is often noticeable and can be quite uncomfortable for individuals with lactose intolerance.
Visible Peristalsis and Hypoactive Bowel Sounds are not typically associated with lactose intolerance:
- Visible Peristalsis: This may be seen in more severe cases of gastrointestinal distress but is not a primary symptom of lactose intolerance. It can indicate other issues like bowel obstruction.
- Hypoactive Bowel Sounds: These are often associated with reduced bowel activity or ileus (a condition where the bowel is not functioning properly), which is not a typical finding in lactose intolerance. Instead, individuals with lactose intolerance usually experience normal or increased bowel sounds due to increased gas production and bowel activity.
In summary, abdominal distention, occasional diarrhea, and flatus are key clinical findings associated with lactose intolerance due to the fermentation of undigested lactose in the colon.
