DHA Radiotherapy Technologist - Why Exam Edge Sample Questions

Which is not a complication of paracentesis?

Correct Answer:
high blood pressure.


paracentesis is a medical procedure that is primarily used to remove excess fluid that has accumulated in the abdomen, a condition known as ascites. ascites may result from various causes including liver diseases such as cirrhosis, heart failure, kidney failure, or cancer. the procedure involves the insertion of a needle or a catheter into the abdominal cavity to drain the fluid. this can help relieve pressure in the abdomen, improve breathing, and allow for the analysis of the fluid to diagnose underlying conditions.

the procedure is relatively quick, typically taking about 20 to 30 minutes, and is usually performed under local anesthesia. while paracentesis is generally safe, it does carry some potential risks and complications. common complications include low blood pressure (hypotension) due to the rapid removal of large volumes of fluid which can decrease the blood volume. other risks include bleeding, infection, puncture of internal organs such as the bladder or bowel, and leakage of ascitic fluid at the puncture site.

fever can sometimes occur following the procedure if an infection develops either at the site of the needle insertion or internally if a bowel or organ is accidentally punctured. severe abdominal pain and blood in the urine are also possible if damage occurs to internal structures during the procedure.

however, high blood pressure (hypertension) is not typically a direct complication of paracentesis. in fact, the removal of fluid can potentially lead to a decrease in blood pressure, not an increase. high blood pressure as a complication could be more associated with other underlying health conditions or different medical interventions, but it is not a recognized risk directly attributed to the paracentesis procedure itself.

therefore, when considering the possible complications of paracentesis, high blood pressure is not one of them. this procedure is more likely to cause low blood pressure, particularly if a large volume of fluid is removed. it’s important for healthcare providers to monitor vital signs before, during, and after the procedure to manage any immediate changes in the patient's condition.

During a PA projection of the chest, the central ray targets the:

Correct Answer:
inferior angle of the scapula


in radiographic imaging, particularly during a posteroanterior (pa) chest projection, precision in directing the central ray (cr) is crucial for accurately capturing the anatomical structures of interest. the pa chest projection is one of the most common radiographic views used to examine the thoracic cavity, including the lungs, heart, and major vessels.

for a pa chest projection, the patient is positioned standing upright with their chest pressed against the image receptor, facing away from the x-ray tube. the arms are typically placed on their hips with elbows flexed, and shoulders rolled forward to move the scapulae laterally and away from the lungs to avoid superimposition over the lung fields.

the central ray in a pa chest projection is aimed perpendicularly to the image receptor. the specific anatomical landmark targeted by the central ray is the inferior angle of the scapula, which approximately corresponds to the t7 vertebral level. this targeting is critical because positioning the central ray at this level ensures an optimal visualization of the lungs, heart, and diaphragm without distortion.

the inferior angle of the scapula is chosen as the focal point because it is centrally located in the thoracic region and provides a balanced perspective of both the upper and lower aspects of the lungs. this ensures that the most significant thoracic structures are included within the frame of the radiograph, facilitating a comprehensive evaluation of the chest.

if the central ray were directed too high or too low compared to this point, it could result in either the apices of the lungs being cut off or the bases of the lungs not being fully visualized, respectively. therefore, correct placement of the central ray at the level of the inferior angle of the scapula is essential for a diagnostic-quality image.

in summary, during a pa projection of the chest, the central ray's precise targeting of the inferior angle of the scapula ensures an effective and comprehensive evaluation of the thoracic cavity. this technique helps healthcare providers to accurately diagnose and assess various conditions affecting the chest area.
