The nurse is caring for a client in labor and discovers late decelerations of the fetal heart rate.
What does the nurse know as the reason for this type of deceleration?
Uteroplacental insufficiency
Maternal hypotension
Cord compression
Head compression
The Correct Answer is A
A. Late decelerations are associated with uteroplacental insufficiency, indicating that the baby is not getting enough oxygen during contractions.
B. Maternal hypotension can lead to decreased perfusion but is more likely associated with variable decelerations.
C. Cord compression is often associated with variable decelerations, not late decelerations.
D. Head compression typically does not cause late decelerations; it may be associated with early decelerations.

Correct Answer is ["A","B"]
Explanation
A. Effacement refers to the thinning of the cervix, making it easier for the cervix to dilate during labor.
B. Effacement also involves the shortening of the cervix, contributing to the progressive dilation during labor.
C. Engagement refers to the descent of the fetal head into the pelvic inlet, not a part of effacement.
D. Effacement does not involve the cervix becoming wider; dilation refers to the opening of the cervix.
E. Effacement does not involve the cervix becoming lower; descent of the presenting part is associated with engagement.
Correct Answer is ["67"]
Explanation
To calculate the flow rate in mL/hr, we need to use the following formula:
Flow rate (mL/hr) = Dose (g/hr) x Volume (mL) / Concentration (g)
In this case, the dose is 2 g/hr, the volume is 1000 mL, and the concentration is 30 g. Plugging these values into the formula, we get:
Flow rate (mL/hr) = 2 x 1000 / 30 Flow rate (mL/hr) = 66.67
To follow the rounding rules, we need to round this answer to the nearest whole number.
Therefore, the flow rate in mL/hr is 67.
