A patient who is constipated has just received a mineral oil-retention enema. The nurse encourages this patient to hold this enema for a minimum of how long?

Option A is the most appropriate choice. Applying a skin protective lotion after cleaning the backside can help moisturize and nourish the dry and thin perineal skin. It creates a barrier that helps protect the skin from further irritation and excoriation. It is important to choose a skin protective lotion specifically formulated for perineal care and suitable for older adults.

Let's go over the other options:

Option B is incorrect because taping an occlusive moisture barrier pad to the skin may not be necessary for mild excoriation and can potentially further irritate the skin. It is not the most appropriate intervention in this situation

Massage the skin with deep kneading pressure in (option C) is incorrect because deep kneading pressure may cause further irritation to the already dry and thin perineal skin, potentially worsening the excoriation. Gentle and cautious care should be taken to avoid excessive pressure or friction

Thoroughly scrub the skin with a washcloth and hypoallergenic soap in (option D) is incorrect because thoroughly scrubbing the skin with a washcloth and hypoallergenic soap can be too harsh for the already compromised perineal skin. It may cause further dryness, irritation, and damage to the skin. Gentle cleansing using mild, non-irritating soap and soft cloths or disposable wipes is more appropriate.

A large volume enema is usually administered with 500 to 1000 mL of fluid. This amount of fluid helps to promote a thorough cleansing of the colon and facilitate the removal of fecal material. However, it's important to note that the specific volume may vary depending on the patient's individual needs, clinical situation, and healthcare provider's instructions.

300 to 500 mL in option (A) is incorrect because its wont help to promote a thorough cleansing of the colon.

200 to 100 mL in option (C) is incorrect because it will not facilitate the removal of fecal material.

50 to 150 ml in option (D) is incorrect because it describes smaller volumes of fluid that would be more suitable for other types of enemas, such as small volume enemas or retention enemas, which have different purposes and indications.
