A client with a fractured femur and pelvic fractures should be monitored for which signs/symptoms?

The choice indicating the need to monitor for tachycardia and hypotension is crucial in the context of fractures, particularly with femur and pelvic injuries. These types of fractures can lead to significant internal bleeding due to the proximity of major blood vessels and the large volume of blood contained within the pelvic area. This can result in hypovolemic shock, where the body's circulatory system is compromised due to decreased blood volume.

Tachycardia, or an increased heart rate, is often the body's compensatory response to maintain adequate circulation and blood flow when there is a loss of blood volume. Hypotension, or low blood pressure, typically occurs as the volume of circulating blood decreases, leading to insufficient pressure to keep blood flowing to vital organs. Therefore, monitoring for these signs is essential to quickly identify and manage potential complications such as shock or hemorrhage.

The other choices, while they might also develop in the context of fractures, do not appropriately reflect the immediate critical risks associated with femur and pelvic fractures. For example, decreased heart rate and increased blood pressure are generally not expected physiological responses to significant trauma or hemorrhage. Muscle spasms and swelling can occur but are not as critical as monitoring for vital signs related to blood loss. Local
