Extract:
Question 1 of 5
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?
Correct Answer: A
Rationale: Vaginal ultrasound directly visualizes the implanted embryo, providing the highest accuracy compared to biochemical tests or subjective symptoms, which can be misleading.
Question 2 of 5
The nurse observes a fetal heart rate pattern on the monitor: baseline 160 beats per minute with minimal variability, a decrease to 150 beats per minute beginning after the contraction starts and returns to baseline after the contraction ends. Which finding should the nurse document in the electronic medical record?
Correct Answer: B
Rationale: The described pattern matches late decelerations, indicating potential utero-placental insufficiency, as the fetal heart rate decreases after the contraction starts and recovers post-contraction.
Question 3 of 5
A client who is 38 weeks pregnant is concerned her baby might get a communicable disease before any immunizations are given. Which physiological mechanism should the nurse use when responding to the mother's concerns?
Correct Answer: A
Rationale: Passive immunity from maternal antibodies provides newborns with initial protection against communicable diseases, lasting several months until their immune system matures.
Question 4 of 5
Following an amniocentesis, a client verbalizes several concerns. Which reported finding indicates to the nurse that the client is experiencing a complication from the amniocentesis?
Correct Answer: A
Rationale: Low back pain and pelvic cramping post-amniocentesis may signal complications like premature labor or infection, requiring immediate evaluation.
Question 5 of 5
After two miscarriages, a client is instructed to increase her daily intake of foods that includes folic acid. The client does not like green leafy vegetables and states she is allergic to soy. Which food should the nurse suggest that the client eat to obtain folic acid?
Correct Answer: D
Rationale: Strawberries are a good source of folic acid, suitable for the client's dietary restrictions, unlike yogurt, milk, or collard greens, which either lack folic acid or are disliked.
