Final answer:

A hypertonic (fleet) enema is used for 'enemas until clear' to induce bowel movements. It's important to use isotonic solutions like normal saline for intravenous therapy to maintain cell integrity. Oral route is convenient for antimicrobial home administration, and antiseptics are suitable for microbial control on living tissues.

Step-by-step explanation:

To administer enemas until clear, a hypertonic (fleet) enema is typically used. This type of enema works by drawing water into the colon, which helps to induce bowel movements.

When considering intravenous solutions, it is important to use an isotonic solution, such as normal saline or lactated Ringer's solution, because it has the same osmotic pressure as the body fluids, which prevents cells from swelling or shrinking. This is crucial for maintaining cell integrity and proper function.

For home administration of an antimicrobial to treat a systemic infection, an oral route is often considered the most appropriate and convenient. In comparison to intravenous or parenteral methods, oral administration does not require specialized medical equipment or assistance.

The correct substance for microbial control on tissues to prevent infection would typically be an antiseptic, as these are specifically intended for use on living tissues to kill or inhibit pathogenic microorganisms.

Final answer:

Hypertonic (fleet) enema is used to administer "enema until clear" due to its ability to draw water into the bowel. Isotonic solutions like normal saline are usually administered intravenously to maintain electrolyte balance.

Step-by-step explanation:

To administer an "enema until clear," which is a procedure often required prior to colonoscopy or surgery to ensure the colon is free of solid matter, a Hypertonic (fleet) enema is typically used. This type of enema works by drawing water into the bowel from surrounding tissues, resulting in a bowel cleansing effect. Tap water enemas are generally avoided for repeated use due to the risk of water intoxication or electrolyte imbalance. Normal saline is not typically the choice for repeated enemas because it is isotonic and less effective at drawing water into the colon compared to hypertonic solutions.

It is important to note that isotonic solutions, such as normal saline and lactated Ringer's solution, are typically used for intravenous administration to prevent osmotic imbalances. In the case of rehydrating a dehydrated patient intravenously, isotonic saline would be preferred to maintain a balance of electrolytes and prevent cell damage.
