Which of the following is a primary indication for performing a nonstress test during pregnancy?

To determine the exact gestational age of the fetus

To measure the amniotic fluid volume

To confirm the presence of labor contractions

To assess fetal well-being in cases of suspected fetal growth restriction

Answer and Explanation

The Correct Answer is D

A. To determine the exact gestational age of the fetus. Gestational age is estimated via ultrasound and fundal height, not an NST.

B. To measure the amniotic fluid volume. Amniotic fluid volume is assessed with an ultrasound and amniotic fluid index (AFI), not an NST.

C. To confirm the presence of labor contractions. An NST does not confirm labor contractions; it evaluates fetal heart rate in response to fetal movement.

D. To assess fetal well-being in cases of suspected fetal growth restriction. An NST evaluates fetal oxygenation and well-being, making it useful in cases of intrauterine growth restriction (IUGR) or other concerns about fetal health.

Correct Answer is C

Explanation

A. Viability of the fetus: The client reports fetal movement, indicating viability. While fetal well-being is always a consideration, the priority here is determining the cause of the bleeding.

B. The biparietal diameter: The biparietal diameter (BPD) is used to assess fetal head size and estimate gestational age, which is not relevant to the client’s bleeding.

C. Location of the placenta: The priority in evaluating third-trimester bleeding is ruling out placenta previa (where the placenta covers the cervix) or placental abruption. Ultrasound helps determine if the placenta is improperly positioned.

D. Fetal lung maturity: Fetal lung maturity is assessed when preterm delivery is being considered, typically before 37 weeks, but it is not the primary concern in assessing vaginal bleeding.

A. 3+ protein in the urine B. 1+ pitting sacral edema C. Blood pressure 148/98 mm Hg D. Deep tendon reflexes of +1

Correct Answer is D

Explanation

A. 3+ protein in the urine: Severe proteinuria (≥2+ on dipstick) is a diagnostic criterion for preeclampsia. The presence of 3+ proteinuria is consistent with preeclampsia.

B. 1+ pitting sacral edema: Edema is common in preeclampsia, especially in dependent areas like the hands, face, and sacral region. This is not inconsistent with preeclampsia.

C. Blood pressure 148/98 mm Hg: Preeclampsia is defined as blood pressure ≥140/90 mm Hg after 20 weeks of gestation, with proteinuria or other signs of organ dysfunction. A BP of 148/98 mm Hg is consistent with preeclampsia.

D. Deep tendon reflexes of +1: Hyperreflexia (+3 or +4 reflexes) is a common finding in preeclampsia due to neuromuscular irritability. A +1 reflex response indicates diminished reflexes, which is not characteristic of preeclampsia.
