FREE Neonatal Intensive Care Nurse MCQ Questions and Answers

Question 1

A G2P2 patient at 32 weeks' gestation enters at the triage unit complaining of frequent uterine contractions. Her pregnancy history involves a 34-week premature birth. The nurse does electronic fetal monitoring and takes a detailed history before evaluating her. The patient reports no bleeding or membrane rupture. She hasn't had a vaginal examination or sexual activity in over 24 hours. In this case, the biochemical marker effective for predicting premature delivery is:

Accepted Answer

Fetal fibronectin

Answer

In the late second and early third trimesters, fetal fibronectin (fFN) is rare in cervicovaginal secretions. fFN is an extracellular glycoprotein that acts as an adhesive between the fetal membrane and the uterine wall and is damaged by inflammation. After a positive test result, a premature delivery within two weeks is likely. Cervical ferritin is an inflammatory marker, not a biomarker, and its presence supports the hypothesis that infection is a mediator of premature delivery. In both term and preterm pregnancies, maternal plasma corticotropin-releasing hormone concentrations are high. It appears to be a part of the same labor route regardless of gestation. Placental alpha-microglobulin-1 is a protein discovered to be a biomarker for membrane rupture.

Question 2

At 32 weeks' gestation, a lady arrives at the triage unit concerned because she has been "leaking fluid" from her vagina for the previous hour. She claims she hasn't felt any contractions and that fetal activity is typical. AmniSure, a bedside immunoassay, is used. The test detects a glycoprotein that is prevalent in amniotic fluid. This glycoprotein is known as:

Accepted Answer

Placental alpha-microglobulin-1

Answer

Premature membrane rupture is one of the most prevalent pregnancy problems that results in an infant being admitted to the NICU. AmniSure ROM is a bedside immunoassay test that is straightforward, easy to conduct, quick (5-10 minutes), and less invasive. This test detects a placental glycoprotein that is rich in amniotic fluid but low in maternal blood and cervicovaginal secretions. Prolactin is in charge of priming the breast tissue in preparation for lactation, whereas Alpha-fetoprotein is used to detect neural tube abnormalities (high) and Down Syndrome (low). Fetal fibronectin is an extracellular glycoprotein that acts as an adhesive between the fetal membranes and the uterine wall and is used to predict premature delivery.

Question 3

The BEST indication of fetal oxygenation status during labor when electronic fetal monitoring is used is:

Accepted Answer

Moderate fetal heart rate variability

Answer

Moderate fetal heart rate (FHR) variability is closely related with an arterial umbilical greater than 7.15. Normal FHR variability gives confidence concerning fetal health and the absence of metabolic acidemia. FHR variability is the most accurate predictor of fetal well-being. Variability is the most significant single FHR attribute. Regardless of gestational age, the FHR baseline is 110 to 160 bpm. Decelerations are caused by head compression, umbilical cord compression, or a temporary disruption in oxygen delivery. The nonstress test is based on accelerations, which are strongly predictive of the absence of fetal metabolic acidemia. They occur in tandem with fetal movement.

Question 4

The primary method for assessing fetal health at the moment is the biophysical profile (BPP), which examines a variety of functions that the central nervous system regulates and that are oxygenation-sensitive. The BPP includes the following five variables:

Accepted Answer

Fetal tone, fetal breathing, fetal movement, non-stress test, and amniotic fluid volume

Answer

According to the biophysical profile (BPP), more variables are a stronger predictor of outcome than fewer ones. Each indication receives a value of 0 if it is missing or 2 points if it is present, and management is based on the overall score. A score of 10 suggests that fetal hypoxia is quite improbable. For the remaining components, the BPP consists of a nonstress test employing an electronic fetal monitor and real time restricted ultrasonography to watch the fetus. Fetal tone, fetal movement, fetal breathing, the nonstress test, and the amniotic fluid index are among the components. The BPP does not account for fetal posture or heart rate.

Question 5

An ideal gestational duration for glucose screening in women at low risk of developing gestational diabetes in pregnancy is:

Accepted Answer

24-28 week's gestation

Answer

Patients are tested between 24-28 weeks' gestation if they meet the low-risk criteria for gestational diabetes (25 years, normal weight, belonging to an ethnic group with a low prevalence of diabetes, no first-degree relatives with diabetes, no history of abnormal glucose tolerance, and no history of poor obstetric outcome). Patients with risk factors (>35 years, BMI >30, history of gestational diabetes, delivery of a large-for-gestational-age infant, polycystic ovarian syndrome, strong family history of diabetes) should have a plasma glucose screening at their first prenatal visit, followed by another at 24-28 weeks.
