A nurse is providing teaching to a client who is primigravid and is scheduled to have an abdominal ultrasound.
Which of the following statements by the client indicates an understanding of the teaching?
A “I won’t apply perfumed lotion to my abdomen before the test.”
B “I can’t have anything to eat after midnight.”
C “I need to take a stool softener the night before the test.”
D “I will drink water before the test until my bladder feels full.”
The correct answer and Explanation is :
The correct answer is:
D: “I will drink water before the test until my bladder feels full.”
Explanation:
Abdominal ultrasounds in early pregnancy require a full bladder for optimal imaging. A full bladder pushes the uterus up and acts as an acoustic window, making it easier for the sound waves to travel through fluid and produce a clearer image of the fetus. This is especially important for first-trimester ultrasounds when the uterus is still small and deep in the pelvis. Drinking water and holding urine until the bladder is full enhances the visibility of the uterus and the developing fetus.
The other options are not relevant or necessary for this procedure:
- A: “I won’t apply perfumed lotion to my abdomen before the test.”
While avoiding lotions might be important for some types of imaging to prevent interference with the ultrasound gel, it is not commonly emphasized in teaching for abdominal ultrasounds. Lotions are not significant enough to distort the ultrasound image in this context. - B: “I can’t have anything to eat after midnight.”
This restriction is typically for tests that require fasting, such as certain blood tests or abdominal procedures (like abdominal ultrasounds assessing gallbladder function). However, it is not applicable for routine obstetric ultrasounds. - C: “I need to take a stool softener the night before the test.”
There is no need to take a stool softener before an ultrasound. Bowel contents do not typically interfere with abdominal ultrasound imaging in pregnant women, as the primary focus is the uterus and fetus.
Teaching clients to drink water and ensure a full bladder helps ensure a successful ultrasound.
