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 A
Explanation
Choice A rationale
Low back pain and pelvic cramping after amniocentesis can indicate complications such as premature labor or infection, which requires immediate medical attention.
Choice B rationale
Headache and blurred vision are less indicative of complications from amniocentesis; these symptoms are more commonly associated with conditions like preeclampsia.
Choice C rationale
Increased fetal movement is not typically a complication of amniocentesis and does not directly relate to immediate maternal or fetal health concerns.
Choice D rationale
Epigastric pain is not a specific complication of amniocentesis; it is more commonly associated with gastrointestinal issues or, in severe cases, preeclampsia.
Correct Answer is C
Explanation
Choice A rationale
Increasing IV infusion rate can exacerbate fluid overload and hypertension, potentially worsening the patient's condition. Monitoring fluid status and adjusting infusions cautiously is critical to avoid iatrogenic complications.
Choice B rationale
Assessing vital signs helps detect early signs of complications such as hypovolemia, infection, or abnormal bleeding, facilitating timely intervention to prevent further deterioration.
Choice C rationale
Massaging the fundus promotes uterine contraction, reducing the risk of postpartum hemorrhage. Effective fundal massage can control bleeding and stabilize the patient following childbirth.
Choice D rationale
Notifying the healthcare provider ensures prompt communication of any changes in the patient's condition, enabling timely medical intervention and potentially preventing adverse outcomes.
