When interpreting fetal heart rate patterns, what other information is considered in addition to baseline and variability?

Maternal heart rate

Gestational age

Uterine contractions

Presence of accelerations and decelerations

Answer and Explanation

The Correct Answer is C

A. Maternal heart rate: While the maternal heart rate is important, it is not directly related to interpreting FHR patterns. However, it is necessary to differentiate between the maternal and fetal heart rate on the monitor.

B. Gestational age: While gestational age affects fetal heart rate (younger fetuses tend to have higher baseline rates), it is not a direct component of FHR interpretation.

C. Uterine contractions: Uterine contractions are crucial in FHR interpretation because they influence perfusion to the fetus. Decelerations occurring with contractions may indicate fetal distress (e.g., late decelerations suggest uteroplacental insufficiency).

D. Presence of accelerations and decelerations: Accelerations and decelerations provide key information about fetal well-being. Accelerations indicate fetal well-being, while decelerations may signal hypoxia, cord compression, or uteroplacental insufficiency.

Correct Answer is D

Explanation

A. Increase the rate of maintenance IV infusion. Increasing IV fluids may help improve placental perfusion, but it is not the first action. Repositioning the client takes priority to improve blood flow before considering IV adjustments.

B. Administer oxygen using a nonrebreather mask. Oxygen is beneficial in improving fetal oxygenation, but positioning the client laterally should be done first to optimize blood flow before oxygen administration.

C. Elevate the client’s legs. Elevating the legs may be helpful in cases of hypotension, but this scenario describes late decelerations, which are related to uteroplacental insufficiency.

D. Place the client in the lateral position. Late decelerations are caused by uteroplacental insufficiency, leading to fetal hypoxia. The first action is to reposition the client to the lateral position, which improves blood flow to the placenta and enhances fetal oxygenation.

A. A client who has a history of preterm labor B. A client who has been exposed to AIDS C. A client who has mitral valve prolapse D. All of the clients

Correct Answer is D

Explanation

A. A client who has a history of preterm labor. A history of preterm labor is not an indication for MSAFP screening. MSAFP is primarily used to detect neural tube defects (e.g., spina bifida) and chromosomal abnormalities (e.g., Down syndrome).

B. A client who has been exposed to AIDS. HIV/AIDS exposure does not impact MSAFP levels and is not an indication for the test. The focus in these clients is viral load monitoring and antiretroviral therapy.

C. A client who has mitral valve prolapse. Mitral valve prolapse does not affect fetal development in a way that would require MSAFP screening.

D. All of the clients. It is a standard screening test offered to all pregnant clients during the second trimester. The test is recommended for detecting fetal neural tube defects and certain chromosomal abnormalities, typically offered between 15-20 weeks of gestation.
