The nurse instructs a pregnant client that the purpose of an amniocentesis at 36 weeks gestation is for:

Identifying the sex of the fetus.

Detection of metabolic disorders.

Determining fetal lung maturity.

Identification of abnormal fetal cells.

Answer and Explanation

The Correct Answer is C

Choice A rationale

The sex of the fetus can be determined earlier through ultrasound or blood tests, making amniocentesis at 36 weeks unnecessary for this purpose.

Choice B rationale

Detection of metabolic disorders can also be done earlier in the pregnancy through other tests. Amniocentesis at 36 weeks is not typically used for this purpose.

Choice C rationale

Determining fetal lung maturity is a primary reason for performing an amniocentesis at 36 weeks gestation. This test assesses whether the fetus's lungs are developed enough for the baby to breathe independently after birth.

Choice D rationale

Identification of abnormal fetal cells can be done earlier in pregnancy through amniocentesis or other genetic tests. It is not the primary reason for amniocentesis at 36 weeks.

Correct Answer is {"A":{"answers":"A"},"B":{"answers":"B"},"C":{"answers":"C"},"D":{"answers":"A"},"E":{"answers":"A"}}

Explanation

Weight loss of 2.8 kg (6.2 lb): Consistent - Significant weight loss is a classic symptom of hyperemesis gravidarum. The client has lost more than 5% of her pre-pregnancy weight, which is concerning and supports this diagnosis.

Hematocrit: 30%: Not Consistent - Hematocrit measures the proportion of red blood cells in the blood. In hyperemesis gravidarum, the hematocrit may be elevated due to dehydration, not decreased. Therefore, this value is not consistent with the typical presentation.

Vaginal spotting: Not Relevant - While vaginal spotting can be concerning in pregnancy, it is not a specific sign of hyperemesis gravidarum and does not directly relate to the diagnosis of severe nausea and vomiting.

Heart rate: 110/min: Consistent - Tachycardia (elevated heart rate) can occur due to dehydration and the body’s response to prolonged vomiting, making this finding consistent with hyperemesis gravidarum.

BUN: 28 mg/dL: Consistent - Blood urea nitrogen (BUN) is elevated in this client, suggesting dehydration. Dehydration is a common complication of hyperemesis gravidarum due to persistent vomiting and poor oral intake.

A. This is a possible sign of pregnancy. B. This is a positive sign of pregnancy. C. This is a presumptive sign of pregnancy. D. This is a probable sign of pregnancy.

Correct Answer is B

Explanation

Choice A rationale

Possible signs of pregnancy include symptoms like nausea, but feeling the baby move is not one of them.

Choice B rationale

Feeling fetal movements felt by both the mother and examiner is a positive sign of pregnancy as it confirms fetal presence.

Choice C rationale

Presumptive signs of pregnancy are symptoms felt by the woman, such as missed periods, but not confirmed fetal movements.

Choice D rationale

Probable signs include changes observed by an examiner, like a positive pregnancy test, but not confirmed fetal movements.
