For an adult donor with a heart rate of 140, BP of 90/60, and Na+ of 168, what should the Procurement Coordinator administer?

For an adult donor with a heart rate of 140, BP of 90/60, and Na+ of 168, what should the Procurement Coordinator administer?

• A. Dopamine
• B. LR
• C. 0.45% NS
• D. Hespan

Answer: (C)

In this scenario, the physiological parameters indicate that the donor is likely experiencing dehydration or hypovolemia, as evidenced by the elevated heart rate (tachycardia), low blood pressure (hypotension), and elevated sodium level (hypernatremia). The appropriate intervention in such cases is to administer a fluid that can help restore the intravascular volume and normalize these parameters. 0.45% NS, or half-normal saline, is a hypotonic solution that can help improve hydration status by providing free water and allowing for sodium correction. It gently addresses dehydration without introducing high sodium content, which can be crucial for managing the donor’s elevated sodium levels. Furthermore, the hypotonic nature of 0.45% NS helps decrease the osmolality of the extracellular fluid, thereby facilitating a balance in fluid distribution among compartments. In contrast, the other options are not suitable for the desired fluid replacement and electrolyte management in this instance. Dopamine is primarily a vasopressor and would not correct the underlying fluid deficit. Lactated Ringer's (LR) is an isotonic solution and might have been considered, but it is not specifically tailored to address the hypernatremia alongside fluid deficit. Hespan, a volume expander, may be
