  • 2. 

    Preparing a patient for an upper gastrointestinal study includes all of the following except:

    • An enema 4 hours before the procedure as needed

    • Fasting the patient for 12 - 24 hours

    • Sedation as needed

    • Administration of oral emetic such as hydrogen peroxide

    Correct Answer
    A. Administration of oral emetic such as hydrogen peroxide
    Explanation
    The correct answer is administration of oral emetic such as hydrogen peroxide. This is because an upper gastrointestinal study requires the patient to have an empty stomach, hence the fasting for 12-24 hours. Sedation may be needed to keep the patient calm during the procedure. An enema may be given to clear the lower gastrointestinal tract. However, administration of an oral emetic such as hydrogen peroxide is not necessary for this procedure.

    Which view is contraindicated duiring an esophagography and why?

    • Dorsoventral; contrast agent in the esophagus superimposed over the heart

    • Left lateral; potential for aspiration

    • Ventrodorsal; potential for aspiration

    • Right lateral; contrast agent in the esophagus superimposed over the heart

    Correct Answer
    A. Ventrodorsal; potential for aspiration
    Explanation
    NOTE: the potential for aspiration should always be considered in any view, especially if the animal is sedated.

    Which of the following is a suitable agent to use as an enema before a lower gastrointestinal study?

    • Barium sulfate

    • Warm water

    • Soapy water

    • Mineral oil

    Correct Answer
    A. Warm water
    Explanation
    Warm water is a suitable agent to use as an enema before a lower gastrointestinal study because it helps to soften and lubricate the stool, making it easier to pass. It also helps to cleanse the colon and remove any residual fecal matter. Using warm water as an enema is a safe and gentle method that does not pose any risk of complications or side effects.

    What is the disadvantage of using low-osmolar contrast media?

    • Expense

    • Short shelf life

    • Can be used for myelography but not intravascularly

    • Can be used intravascularly but not for myelography

    Correct Answer
    A. Expense
    Explanation
    The disadvantage of using low-osmolar contrast media is its expense. This means that it can be costly to use this type of contrast media in medical procedures.

    Rate this question:

  • 6. 

    Which of the following statements is false?

    • All patients who will receive a gastrointestinal contrast study must receive an enema

    • General anesthesia and atropine are contraindicated for gastrointestinal contrast studies because of the degree to which they alter gastrointestinal motility

    • If an enema is administered, the contrast radiograph should not be taken until at least 1 hour postadministration

    Correct Answer
    A. All patients who will receive a gastrointestinal contrast study must receive an enema
    Explanation
    The statement "all patients who will receive a gastrointestinal contrast study must receive an enema" is false. Not all patients require an enema before a gastrointestinal contrast study. The decision to administer an enema depends on the specific case and the clinical judgment of the healthcare provider.

    What is the most diagnostic examinatino of the gastric mucosal lining?

    • Double-contrast gastrogram

    • Double-contrast upper gastrointestinal study

    • Positive-contrast gastrogram

    • Negative-contrast gastrogram

    Correct Answer
    A. Double-contrast gastrogram
    Explanation
    A double-contrast gastrogram is the most diagnostic examination of the gastric mucosal lining. This procedure involves the use of both positive and negative contrast agents to provide a detailed view of the stomach lining. The positive contrast agent highlights the surface of the stomach, while the negative contrast agent fills the spaces between the folds of the mucosa, allowing for better visualization of any abnormalities or lesions. This technique provides a comprehensive evaluation of the gastric mucosal lining and is often used to detect conditions such as ulcers, tumors, or inflammation.

    What additional view can be helpful for assessing a positive-contrast cystogram, especially in a male patient?

    • Lateral view with a horizontal beam

    • Lateral cubitus

    • Dorsoventral

    • Oblique

    Correct Answer
    A. Oblique
    Explanation
    An oblique view can be helpful for assessing a positive-contrast cystogram, especially in a male patient. This view allows for a better visualization of the bladder and its surrounding structures from a different angle, which can aid in the detection of any abnormalities or pathology.

    Which of teh following is the safest combinatino of agents to sue for a cystogram?

    • Barium sulfate and carbon dioxide

    • Sodium iodide and nitrous oxide

    • Triiodinated ionic compounds and carbon dioxide

    • Triiodinated ionic compounds and room air

    Correct Answer
    A. Triiodinated ionic compounds and carbon dioxide
    Explanation
    Triiodinated ionic compounds and carbon dioxide are the safest combination of agents to use for a cystogram. This is because triiodinated ionic compounds are commonly used as contrast agents in medical imaging, and they are considered safe and effective for this procedure. Carbon dioxide is used as a gas to distend the bladder during a cystogram, and it is also considered safe. Therefore, using these two agents together would provide the safest option for performing a cystogram.

    Rate this question:

  • 10. 

    Which of the following are recommended for performing intravenous pyelography?

    • Placement of indwelling urinary catheter

    • Fast 12 - 24 hours before

    • Placement of abdominal pressure wrap during procedure

    • Obtain urinary samples immediately after procedure

    Correct Answer
    A. Fast 12 - 24 hours before
    Explanation
    Fasting 12-24 hours before intravenous pyelography is recommended because it helps to ensure that the patient's stomach is empty during the procedure. This is important because contrast dye is used during the procedure, and having food in the stomach can increase the risk of nausea, vomiting, and aspiration. Fasting also allows for better visualization of the urinary tract during the procedure.
