Question

The doctor is performing an amniocentesis on the client at 17 weeks gestation to detect genetic anomalies. Which statement indicates the nurse understands the proper instructions for the client having an amniocentesis at 17 weeks gestation? A. After the ultrasound exam, the client should empty the bladder. B. After the ultrasound exam, the client should not void for the amniocentesis. C. The ultrasound exam will be done at least eight hours prior to the amniocentesis. D. The amniocentesis cannot be done prior to 20 weeks gestation.

Short answer

Answer: After the ultrasound exam, the client should not void for the amniocentesis.

Step-by-step solution

Option A

After the ultrasound exam, the client should empty the bladder. This is not accurate, because the client must have a full bladder during the ultrasound examination and should not empty the bladder for the amniocentesis.

Option B

After the ultrasound exam, the client should not void for the amniocentesis. This is the correct statement. Having a full bladder can improve the visibility of the uterus and baby during the ultrasound and helps provide the necessary contrast between the uterus and bladder, making it easier for the doctor to perform the amniocentesis safely.

Option C

The ultrasound exam will be done at least eight hours prior to the amniocentesis. This is incorrect. The ultrasound should be performed immediately prior to the amniocentesis to ensure the most accurate and up-to-date information is available.

Option D

The amniocentesis cannot be done prior to 20 weeks gestation. This is also incorrect. Amniocentesis is typically performed between the 15th and 20th week of the gestation, so it can be done at 17 weeks. From the analysis of all the options, the correct answer is

Option B

After the ultrasound exam, the client should not void for the amniocentesis.
