Calculate the gravity rate for gentamycin 100 mg/100ml with secondary tubing (20gtts/mL) over 60 minutes.

A) Decrease the client's IV fluids:
Sinusoidal fetal heart rate patterns are concerning and typically indicate severe fetal distress, which is often associated with conditions such as fetal anemia, hypoxia, or central nervous system (CNS) damage. Decreasing IV fluids is not an appropriate response to a sinusoidal pattern. The primary focus should be on fetal well-being, not fluid management, in this situation.

B) Prepare the client for an emergent birth:
This pattern is typically associated with severe fetal compromise and is an ominous sign. Immediate intervention is required, and emergent delivery may be necessary to prevent further fetal distress and potential harm. The nurse should promptly notify the healthcare provider and prepare the client for an emergency cesarean delivery or other urgent interventions.

C) Turn the client to a supine position:
The supine position is not recommended for managing fetal distress, as it may decrease uterine blood flow and worsen the situation, especially if the fetus is experiencing hypoxia. The appropriate intervention for addressing a sinusoidal heart rate pattern is not repositioning the client in a supine position, but rather preparing for emergency delivery and providing immediate support to stabilize both mother and fetus.

D) Document the findings:
While it is important to document any fetal heart rate pattern, sinusoidal patterns require immediate action. Documentation alone is not sufficient in this case, as it does not address the potential life-threatening situation for the fetus. The nurse should not delay action, and the focus should be on preparing for emergency birth and notifying the healthcare provider immediately.

A) Flexion:
Flexion is a movement where the fetal head bends forward during labor, which allows the smallest diameter of the head to pass through the birth canal. It is an important part of the labor process but does not refer to the initial descent of the fetus into the pelvis. Flexion typically occurs once the fetus begins to descend into the pelvis.

B) Engagement:
Engagement refers to the initial descent of the fetal head into the pelvis and the passage of the largest part of the fetal head (the biparietal diameter) into the maternal pelvis. This occurs when the fetal head reaches zero station at the level of the ischial spines and is the first cardinal movement of labor. It marks the point at which the presenting part of the fetus enters the pelvic inlet and begins the process of descent.

C) Extension:
Extension is the movement of the fetal head as it exits the birth canal after engagement and descent. The head moves from a flexed position (chin to chest) to an extended position (chin moving away from the chest) as it passes through the birth canal. This movement occurs after engagement and is a part of the expulsion phase, not the initial descent.

D) Expulsion:
Expulsion is the final phase of labor, which occurs after the fetal head has been delivered. It involves the delivery of the rest of the body (shoulders, torso, and legs) following the birth of the head. This is the final cardinal movement, which takes place after engagement, descent, flexion, internal rotation, extension, and external rotation.
