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

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.

A. Preterm labor. B. Premature rupture of membranes. C. Infection. D. Bleeding.

Correct Answer is A

Explanation

A contraction stress test (CST) is a test that simulates labor contractions to see how the baby’s heart rate responds to the stress of uterine contractions.

The biggest risk of the test is that it may cause the pregnant person to go into labor before their due date.

Some possible explanations for the other choices are:

Choice B. Premature rupture of membranes.

This is a condition where the amniotic sac breaks before labor begins.

It can increase the risk of infection and cord prolapse, but it is not a direct complication of CST.

Choice C. Infection.

This is a possible risk of any invasive procedure, but CST is usually done with external fetal monitoring and oxytocin infusion, which do not require breaking the skin or entering the uterus.

Choice D. Bleeding.

This is a potential risk of CST for people who have placenta previa, a condition where the placenta covers the cervix and can detach during contractions.

However, CST is not recommended for people who have placenta previa or other conditions that increase the risk of uterine rupture or bleeding.
