Which statement is the best rationale for assessing maternal vital signs between contractions?

Prepidil (prostaglandin gel) has been ordered for a pregnant woman at 43 weeks of gestation. The nurse recognizes that this medication will be administered to

A primigravida at 39 weeks of gestation is observed for 2 hours in the intrapartum unit. The fetal heart rate has been normal. Contractions are 5 to 9 minutes apart, 20 to 30 seconds in duration, and of mild intensity. Cervical dilation is 1 to 2 cm and uneffaced (unchanged from admission). Membranes are intact. The patient lives 10 minutes from the hospital. The nurse should expect the woman to be

When assessing a woman in the first stage of labor, the nurse recognizes that the most conclusive sign that uterine contractions are effective would be

The nurse recognizes that a woman is in true labor when she states

The nurse providing care for a woman with preterm labor who is receiving terbutaline (Brethine) would include which intervention to identify side effects of the drug?

When assessing a woman in labor, the nurse is aware that the relationship of the fetal body parts to one another is called fetal

Any blockcipher has an inverse.

(The following provides the context for both question 2 and question 3) A company has software for a public-key encryption scheme that is known to be IND-CCA secure under some reasonable assumptions. But the message space for this scheme is only the set of messages up to 1 MB long. At some point they needed to encrypt messages of length more than 1MB but less than 2MB. So they decide to use the existing software to build an encryption scheme in the following way. To encrypt a message , break it into equal parts (for simplicity, let’s assume that all messages have even length) and let a ciphertext be computed as
