A woman who is trying to get pregnant tells the nurse that she was very disappointed several months ago when she was informed that her positive pregnancy test was a false positive. Which method of determining pregnancy provides the greatest degree of accuracy?
Visualization of implantation by vaginal ultrasound.
Maternal blood serum tests positive for alpha-fetoprotein.
Presence of amenorrhea for 2 months.
Reports feeling tired all of the time.
The Correct Answer is A
Choice A rationale
Visualization of implantation by vaginal ultrasound offers the highest accuracy in confirming pregnancy, as it directly visualizes the implanted embryo, eliminating errors associated with biochemical tests.
Choice B rationale
Maternal blood serum tests positive for alpha-fetoprotein do not confirm pregnancy. Alpha-fetoprotein is a marker used primarily for screening fetal abnormalities, not pregnancy determination.
Choice C rationale
The presence of amenorrhea for 2 months can suggest pregnancy but is not definitive due to other potential causes of missed periods, such as hormonal imbalances or stress, reducing its accuracy.
Choice D rationale
Reporting feeling tired all the time is a nonspecific symptom that can result from numerous conditions unrelated to pregnancy, making it an unreliable method for pregnancy determination.

Correct Answer is B
Explanation
Choice A rationale
Encouraging breastfeeding every 2 to 3 hours is contraindicated in HIV-positive mothers. Breastfeeding can transmit HIV to the infant despite maternal antiretroviral therapy, thus alternative feeding methods are recommended to prevent viral transmission.
Choice B rationale
Zidovudine administration within 6 to 12 hours after birth reduces the risk of perinatal HIV transmission. Early prophylaxis is crucial for preventing viral replication and reducing the likelihood of the infant acquiring HIV.
Choice C rationale
Administering antibiotics for 7 to 10 days is unnecessary unless there is evidence of bacterial infection. HIV-exposed infants need antiviral prophylaxis to prevent HIV transmission, not routine antibiotic treatment without specific indications.
Choice D rationale
Delaying the initial bath for 1 to 2 days is not recommended as it doesn't impact HIV transmission risk. Immediate skin cleansing can reduce exposure to maternal blood and bodily fluids, thus it’s standard practice to bathe newborns soon after birth.
Correct Answer is B
Explanation
Choice A rationale
While emergency cesarean birth preparation may be necessary in some cases, the primary focus should be on monitoring labor progression and the effects of oxytocin.
Choice B rationale
Monitoring the intensity, interval, and length of contractions is crucial in assessing the efficacy of oxytocin and ensuring the progress of labor while minimizing the risk of uterine hyperstimulation.
Choice C rationale
Checking the perineum for bulging is important in advanced labor stages but is not the primary focus when managing hypotonic dystocia and oxytocin administration.
Choice D rationale
Monitoring the client’s hourly blood pressure is important for overall health but is secondary to evaluating the contraction patterns and effectiveness of oxytocin in labor progression
