Explanation

A cleansing enema is intended to completely clear the colon of fecal matter, which is critical before intestinal surgery to prevent contamination.
This is achieved by using a large volume of fluid to distend the bowel and trigger strong peristaltic waves.
According to standard nursing practice, the appropriate volume for a large-volume cleansing enema in an adult is between 750 and 1000 mL.
This volume is sufficient to reach and cleanse the entire large intestine effectively.

Option A: This volume is too small for an adult cleansing enema and would not be effective.
Option B: This volume is insufficient to adequately cleanse the colon of an adult.
Option C: While approaching the necessary amount, this volume may not be sufficient for a complete pre-surgical bowel cleanse in an average-sized adult.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Standard volume for a large-volume cleansing enema in an adult as background academic context rather than a clinical decision trigger.
Administering the correct enema volume is a critical nursing responsibility that directly impacts patient safety and procedural outcomes. An incorrect volume can lead to either ineffective bowel preparation or patient harm.
Inadequate cleansing can increase the risk of intra-operative fecal contamination, leading to serious infections like peritonitis. Excessive volume can cause severe cramping, fluid and electrolyte imbalance (especially with hypotonic solutions), and even bowel perforation.
What if? If the patient had congestive heart failure or renal failure, a large-volume tap water (hypotonic) enema would be contraindicated. The body could absorb the excess free water, worsening fluid overload. In this case, an isotonic (normal saline) enema would be the safer choice.

How to Approach the Question

First, identify the key information in the question stem: the procedure is a 'cleaning enema', the patient is a '55 year old client' (an adult), and the purpose is pre-surgical preparation.
Recognize that a pre-surgical cleansing enema for an adult requires a 'large volume' to be effective.
Recall the standard volume ranges for enemas based on the patient's age group.
Evaluate the given options against the standard for an adult (750-1000 mL).
Eliminate the options that represent volumes for pediatric patients (infants, toddlers, adolescents) or for different types of enemas (e.g., small-volume retention enemas).

Concept Tested & Keywords
