A nurse is reinforcing discharge teaching with the family of an older adult client about safety precautions when administering a hypotonic enema to the client. Which of the following instructions should the nurse include in the teaching?
A.
Instruct the client to exhale while inserting the rectal tube.
B.
Administer a second enema if the first has poor results.
C.
Insert the tip of the rectal tube 15 cm (6 in).
D.
Administer the enema using cool tap water.
The correct answer and Explanation is :
The correct answer is B. Administer a second enema if the first has poor results.
Explanation:
Hypotonic enemas are used to relieve constipation or prepare the bowel for certain procedures. They work by introducing a solution (usually tap water) into the rectum and colon, which causes the bowel to distend and stimulates peristalsis. Here’s why the other options are not appropriate:
A. Instruct the client to exhale while inserting the rectal tube.
This instruction is not generally recommended. Inhaling or exhaling doesn’t significantly affect the insertion process. Instead, the focus should be on proper technique and comfort for the client. The rectal tube should be gently inserted, and the client should be positioned in a comfortable manner, often in the left lateral position, to facilitate the process.
C. Insert the tip of the rectal tube 15 cm (6 in).
For a hypotonic enema, the tube should be inserted only about 7.5 to 10 cm (3 to 4 inches) into the rectum. Inserting it deeper than necessary can cause discomfort or injury. It’s essential to follow the manufacturer’s instructions and standard practices for the correct depth of insertion.
D. Administer the enema using cool tap water.
Hypotonic enemas should not be administered using cool or cold water. The solution used for hypotonic enemas is typically at room temperature or warm to prevent cramping and discomfort. Using cool water can cause discomfort and may not be as effective in stimulating bowel movements.
Why Option B is Correct:
If the initial enema does not produce the desired results (i.e., bowel movement), it is generally acceptable to administer a second enema. This approach ensures that the bowel is adequately cleansed and can be necessary for effective treatment. However, care should be taken not to administer too many enemas in a short period, as this can cause electrolyte imbalances and irritation of the rectal mucosa. If the client continues to have issues, it’s important to consult with a healthcare provider for further evaluation and management.
