Final answer:
The BSA of a patient is not a required element on an IV solution label. Proper labeling includes the sequence number, prescribed flow rate, and initials of the preparer and checker. For dehydration, isotonic solutions such as normal saline or lactated Ringer's are used.
Step-by-step explanation:
The element of a proper IV solution label that is not required is c. The BSA (Body Surface Area) of the patient to whom the IV is being administered. A proper IV solution label should contain: a. The sequence number of the bag or bottle, if necessary, b. The prescribed flow rate (ml/hour), and d. The initials of the person who prepared the solution, and the initials of the person who checked it. While the BSA may be relevant for dosing some medications, it is not typically on an IV solution label. When dealing with a dehydrated patient, solutions like normal saline or lactated Ringer's solution are often administered intravenously because they are isotonic, which is important to maintain the fluid balance in the patient's cells.
