Final answer:
The statement can be partially true; water-soluble drugs' distribution can be affected by total body fluid volume, which impacts concentration. Routes of administration include oral and parenteral for convenience, while isotonic saline is used in dehydration to maintain osmotic balance.
Step-by-step explanation:
The statement "Water-soluble drugs such as antibiotics are distributed in smaller volumes due to the decrease in total body fluid volume" could be partially true, depending on the specific context in which it is being discussed. The term 'water-soluble drugs' typically refers to medications that dissolve readily in water, and their distribution in the body can indeed be affected by the volume of body fluids. Total body fluid volume can influence the concentration and distribution of these drugs; for example, a decrease in body fluid volume might lead to higher concentrations of the drug in the body. However, the initial statement does not provide enough context to fully determine its accuracy without additional information about the specific physiological or pathological conditions being considered.
The route of administration of drugs is an important consideration in medicine. Oral administration is often preferred for its convenience, but some drugs do not absorb well in the gastrointestinal tract and thus, alternative methods such as intravenous, topical, or parenteral administration are used depending on the situation. When treating systemic infections at home, oral and sometimes parenteral routes would be appropriate and convenient (A and D).
For a dehydrated human patient requiring intravenous fluids, healthcare providers typically administer saline that is isotonic to body fluids to avoid disrupting osmotic balance. An isotonic saline solution is designed to match the electrolyte balance of the body's fluids, minimizing the risk of causing shifts in fluid concentrations that could lead to hypertonicity or hypotonicity.
