A nurse is caring for a patient who is in labor and is placed on a monitor.How should the nurse determine the duration of contractions?
Count the time from the end of one contraction to the beginning of the next contraction.
Count the time from the middle of one contraction to the end of the same contraction.
Count the time from the beginning of one contraction to the end of the same contraction.
Count the time from the beginning of one contraction to the beginning of the next contraction.
The Correct Answer is C
The correct answer is choice C. Count the time from the beginning of one contraction to the end of the same contraction.
This is because the duration of a contraction is the length of time that the uterine muscle is tightening and relaxing.
The duration is measured from the start of one contraction until the end of that same contraction.
Choice A is wrong because it measures the frequency of contractions, not the duration.
The frequency is the time between the start of one contraction and the start of the next one.
Choice B is wrong because it measures only half of the duration of a contraction.
The middle of a contraction is when the uterine muscle reaches its peak intensity and then starts to relax.
Choice D is wrong because it measures both the duration and the interval of contractions.
The interval is the time between the end of one contraction and the start of the next one.
Normal ranges for contractions during labor are:
• Duration: 30 to 90 seconds
• Frequency: 2 to 5 minutes apart
• Interval: 30 to 120 seconds

Correct Answer is D
Explanation
The correct answer is choice D. Insufficient relaxation of the uterus between contractions.This is also known astachysystoleorhyperstimulation, which can cause fetal distress and uterine rupture.Oxytocin is a hormone that stimulates uterine contractions, but it can also cause them to be too strong or too frequent if given in high doses or for too long.
Choice A is wrong because oxytocin does not decrease body temperature.
Choice B is wrong because oxytocin does not cause maternal cardiac arrhythmias.
Choice C is wrong because oxytocin does not cause urinary retention.
Correct Answer is B
Explanation
The correct answer is choice B. Syphilis.A negative rapid plasma reagin (RPR) test indicates that a patient is probably not infected with syphilis, a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum.The RPR test works by detecting the nonspecific antibodies that your body produces while fighting the infection.
Choice A is wrong because herpes simplex II is a viral infection that causes genital herpes, and it is not detected by the RPR test.
Choice C is wrong because gonorrhea is a bacterial infection caused by Neisseria gonorrhoeae, and it is also not detected by the RPR test.
Choice D is wrong because condylomata are genital warts caused by human papillomavirus (HPV), and they are not detected by the RPR test either.
The RPR test is a screening test, and it can give false-positive results due to other conditions or infections.Therefore, a positive RPR test should always be confirmed by a more specific treponemal test, such as TPPA or FTA-ABS.The RPR test can also be used to monitor the treatment response of syphilis, as the antibody levels should decrease after effective antibiotic therapy.
