A nurse is caring for a client who is at 37 weeks of gestation and received a provider order for group B streptococcus beta-hemolytic culture.
Which of the following statements should the nurse include in the teaching?

Choice A rationale

Fundal height measurement is a simple clinical tool used to estimate gestational age and monitor fetal growth. The correct technique involves using a non-stretchable measuring tape to measure the distance in centimeters from the upper border of the symphysis pubis (a fixed bony landmark) to the highest point of the uterine fundus.

Choice B rationale

A full bladder can artificially elevate the uterine fundus, leading to an overestimation of the fundal height and an inaccurate assessment of fetal growth and gestational age. The nurse should instruct the client to empty their bladder before the measurement is taken to ensure the most reliable result.

Choice C rationale

The fundal height measurement is taken vertically, along the midline of the client's abdomen, from the symphysis pubis to the fundus. Measuring horizontally would not provide a clinically relevant or reproducible measure for assessing fetal growth or comparing against expected gestational age measurements.

Choice D rationale

Fundal height measurement should be performed with the client in the supine position with the knees slightly flexed. Placing the client in the left-lateral position is done to prevent supine hypotension syndrome (aorta-caval compression) but would make a standardized and accurate fundal height measurement impossible to obtain.

Choice A rationale

Fundal massage is the primary intervention for uterine atony and postpartum hemorrhage to stimulate uterine contraction and tamponade bleeding. However, an amniotic fluid embolism (AFE) is characterized by sudden cardiopulmonary collapse, hypoxia, and coagulopathy, where fundal massage is irrelevant to the underlying pathology.

Choice B rationale

AFE involves the sudden entry of amniotic fluid into the maternal circulation, triggering a massive anaphylactoid reaction, acute respiratory distress, and severe refractory hypotension, leading to cardiac and respiratory arrest. Initiating cardiopulmonary resuscitation (CPR) is often immediately required to support life functions.

Choice C rationale

Assisting the client to empty their bladder may be beneficial during labor to allow the fetal head to descend, but it is not a priority intervention for the life-threatening, acute physiological crisis of an AFE. The immediate focus must be on optimizing oxygenation, circulation, and treating the underlying shock and coagulopathy.

Choice D rationale

AFE causes severe pulmonary vasoconstriction and acute respiratory distress, leading to profound hypoxemia. Applying oxygen at 2 L/min via nasal cannula is insufficient for this level of respiratory compromise; the client requires high-flow oxygen, often nonrebreather mask or mechanical ventilation, to maintain adequate arterial oxygen saturation.
