Final answer:
The nurse should implement the intervention of increasing the rate of IV fluids as the first priority for a client in shock with a mean arterial pressure (MAP) of 60 mm Hg and a heart rate of 110 beats per minute.
Step-by-step explanation:
To address a client in shock with a mean arterial pressure (MAP) of 60 mm Hg and a heart rate of 110 beats per minute, the nurse should prioritize increasing the rate of IV fluids as the first intervention. This is because low MAP indicates inadequate blood flow to the tissues, which can lead to ischemia and hypoxia. Increasing the rate of IV fluids can help restore blood pressure and improve circulation to ensure sufficient oxygenation and perfusion.
