Final answer:
Before administering a high volume saline enema, obtain the patient's medical history, current hydration status, and electrolyte levels. Normal saline and lactated Ringer's solution are isotonic, essential for maintaining cell integrity during intravenous fluid administration for dehydration.
Step-by-step explanation:
Prior to administering a high volume saline enema, it is important to gather specific information from the patient to ensure their safety and the effectiveness of the treatment. First, the patient’s medical history should be reviewed for any potential contraindications such as heart failure, renal impairment, or previous reactions to enemas. Additionally, it is essential to assess the patient’s current hydration status and to understand any recent electrolyte levels, especially if the patient is suspected of having an imbalance.
Normal saline and lactated Ringer's solution, which are regularly used as intravenous solutions in medicine, are both isotonic. The isotonicity of these solutions is essential to prevent red blood cells from shrinking (crenation) or bursting (hemolysis), which can occur if the solution is too hypertonic or hypotonic relative to the body’s plasma. For a dehydrated patient, these isotonic solutions are often used to replenish fluids intravenously, providing a balance of electrolytes and water that closely matches the body’s plasma.
