The nurse explains to the patient at 28 weeks’ gestation not to lie flat on their back during the remainder of the pregnancy. What does this precaution prevent?

Correct Answer: D

Rationale: Lying flat can compress the vena cava, leading to reduced blood flow. Other options are unrelated.

Correct Answer: D

Rationale: Maternal perception of fetal movement (quickening) usually begins between 17 and 20 weeks after conception. Because this is her first pregnancy, movement is felt toward the later part of the 17 to 20 weeks. “The baby is moving, but you can’t feel it yet” may be alarming to the woman. “Some babies are quiet and you don’t feel them move” is a true statement; the fetus’ movements are not strong enough to be felt until 17 to 20 weeks; however, this statement does not answer the woman’s concern. Fetal movement should be felt between 17 and 20 weeks; if movement is not perceptible by the end of that time, further assessment will be necessary.

Correct Answer: B

Rationale: An ultrasound can determine the fetus's position. Other tests are not typically used for this purpose.

Correct Answer: A

Rationale: Ovarian hyperstimulation syndrome (OHSS) is a potential complication of egg retrieval, causing bloating and abdominal discomfort.

Correct Answer: C

Rationale: The first 8 weeks are critical as all organ systems are developing, making it a sensitive period for any interruptions.
