A nurse is performing an abdominal ultrasound for a client who is at 28 weeks of gestation.

The nurse should instruct the client to do which of the following before the procedure?

Drink several glasses of water.

Empty her bladder completely.

Lie on her right side

Fast for at least 4 hours.

Answer and Explanation

The Correct Answer is A

The woman should drink several glasses of water before the abdominal ultrasound procedure.

This is because a full bladder helps to push the intestines away and improve the visibility of the uterus and the fetus.

Drinking water also helps to avoid gas buildup in the abdomen, which could interfere with the sound waves.

Choice B is wrong because emptying the bladder would make it harder to see the uterus and the fetus.

Choice C is wrong because lying on the right side would not affect the quality of the ultrasound image.

Choice D is wrong because fasting is not necessary for an abdominal ultrasound, unless instructed by the doctor for a specific reason.

Correct Answer is B

Explanation

An amniotic fluid index (AFI) of 4 cm indicates oligohydramnios, which is a low amount of amniotic fluid.

Oligohydramnios can be caused by various factors, such as uteroplacental insufficiency, rupture of membranes, postterm pregnancy, fetal anomalies, or certain medications.

Oligohydramnios can lead to complications such as fetal death, intrauterine growth restriction, limb contractures, or delayed lung maturation.

Choice A is wrong because an AFI of 8 cm is within the normal range for amniotic fluid volume.

Choice C is wrong because a single vertical pocket of amniotic fluid measuring 3 cm is also within the normal range for amniotic fluid volume.

Choice D is wrong because a single vertical pocket of amniotic fluid measuring 5 cm is also within the normal range for amniotic fluid volume.

Normal ranges for AFI and single vertical pocket are > 5 to < 24 cm and ≥ 2 to < 8 cm, respectively.

A. Administer Rho(D) immune globulin. B. Monitor fetal heart rate C. Assess maternal vital signs D. Obtain an order for an ultrasound exam

Correct Answer is B

Explanation

This is because cramping and vaginal bleeding after an amniocentesis may indicate a possible miscarriage or placental abruption, which can compromise fetal oxygenation and perfusion.

Monitoring fetal heart rate can help detect signs of fetal distress and guide further interventions.

Choice A is wrong because administering Rho(D) immune globulin is indicated for Rh-negative mothers who undergo amniocentesis to prevent isoimmunization, but it is not a priority action in this scenario.

Choice C is wrong because assessing maternal vital signs is important to monitor for signs of infection, hemorrhage, or shock, but it is not as urgent as monitoring fetal well-being.

Choice D is wrong because obtaining an order for an ultrasound exam can help confirm the diagnosis and evaluate the placenta and amniotic fluid, but it is not the first action to take in this situation.
