Chapter 16 Diagnostic tests, X-rays, and Procedures Review Chapter 16 Diagnostic tests, X-rays, and Procedures

Review What do you introduce into the skin to induce a reaction(allergy testing)? Antigen A raised area on the skin that shows a positive reaction? Wheal This is a release of histamine? Hypersensitive reaction

Review This is a life-threatening reaction? Anaphylactic shock The patient must wait for how long after allergy testing? 20 min for possible reaction The patch test is done to determine? The cause of contact dermatitis

Review This procedure is used frequently to diagnose heart disease and dysfunction? Electrocardiogram(EKG/ECG) What indicates the electrical impulses shown from a specific lead on a ECG/EKG? Rhythm strip What are placed on the patient’s limbs and chest and pick up the electrical current produced by the contractions of the heart? Electrodes

Review What is known as the first part of the cardiac cycle? Atrial depolarization(P wave) The QRS wave corresponds to? Depolarization of the right and left ventricles T wave represents? The repolarization or (recovery) of the ventricles Know your lead placements

Review This is anything that causes an interference in the ECG recording? Artifacts This is a stress EGC that is done while a patient is exercising on a treadmill or bicycle under careful supervision? Stress test This is a EKG/ECG test over a period of 24 to 48 hours? Holter monitor Define MRI Magnetic Resonance Imaging What is this test used for? Tube -like structure used to view structures inside the human body

Review What are some contraindications for an MRI? Any metal, including pacemakers, pregnancy What test would you have a patient fast(NPO) midnight, the night before? Abdominal ultrasound What test would you have a patient drink about 30 ounces of fluid 1 hour before? Fetal ultrasound

Review What does KUB stand for? Kidney, ureters, bladder What is this test done for? To diagnosis urinary diseases and disorders This test aids in the diagnosis of breast masses as small as 1 cm in size or less? Mammogram What are some instructions that you would give the patient the day of the mammogram? No deodorants, perfumes, or powders, ask if the patient could be pregnant
