Answer to Question 1

ANS: D
The infusion rate is not increased or may be decreased if the maternal pulse rate remains over 120 beats/min (bpm). A maximum dose of 0.1 mg is above the recommended maximum rate, systolic blood pressure below 110 mm Hg may be a normal finding for this client, and the medication should continue to be increased until the maximum level is reached or contractions stop.

Answer to Question 2

ANS: B
A hypotonic labor pattern indicates that uterine contractions are variable in nature and weak and thus do not affect cervical change in a timely manner. Labor patterns are prolonged in duration and clients are typically comfortable but can become easily tired and frustrated because of the inability of their labor to progress to conclusion. The least likely occurrence is that of fetal distress, because the uterine contraction pattern is not coordinated and/or strong enough to exert pressure.
