NEW QUESTION # 323
How much periodontal attachment loss does a patient have with grade 3 periodontal disease?
Answer: C
Explanation:
Periodontal disease is a progressive inflammatory condition of the periodontal structures, including gingiva, alveolar bone, cementum, and periodontal ligament. Periodontitis is a term used to describe advanced periodontal disease. With inflammation, the gingiva recedes, the alveolar bone resorbs, and the periodontal ligament loses attachment between the tooth and sulcus. A periodontal probe (preferred technique) or radiographs (less sensitive in early disease) are used to measure the length of attachment loss.
% attachment loss = (Length of the cementoenamel junction to the depth of alveolar pocket) / (Length of the cementoenamel junction to length of the root) For example, a dog's canine tooth measures 12 mm from the tip of the root to the cementoenamel junction on radiographs or estimated from the technician's experience based on the dog's size. On probing or radiographs, there is a 6 mm depth pocket. 6 / 12 = 0.50, or 50% attachment loss. It's important to note that it is satisfactory to estimate periodontal attachment loss, and exact measurements and calculations are unnecessary.
*Grade 0: no loss
*Grade 1: no loss
*Grade 2: 0-25% loss
*Grade 3: 25-50% loss
*Grade 4: > 50% loss
NEW QUESTION # 324
During radiography positioning, the thickest part of the body area being imaged should be placed toward the cathode side of the tube to reduce which of the following?
Answer: C
Explanation:
The heel effect refers to the uneven photon distribution that occurs when an x-ray beam leaves the tube. Because of the rate of absorption by the anode target material, x-ray beams are more powerful at the cathode side vs. the anode. To decrease the heel effect, the technician should place the thickest part of the target area on the cathode side of the tube.
Scatter radiation occurs when the beam "bounces" off surfaces and redirects orientation. It does not change with patient positioning.
Focal-film distance is the measure between the focal point and film/sensor and does not change based on body part thickness.
Collimation is a technique of restricting the primary beam to decrease unnecessary patient exposure and scatter and does not change based on body part thickness.
NEW QUESTION # 325
In ultrasonography, the artifact of reverberation indicates the presence of which tissue interface?
Answer: A
Explanation:
Reverberation occurs at an interface with gas or air. Examples include the skin surface and air when a probe is not getting adequate contact (more gel needed), and soft tissue with gas (such as within the respiratory tract and bowel). It appears as evenly spaced white lines on the far side of the interface.
Soft tissue-soft tissue interfaces will produce echoes of varying intensity and brightness. These changes form the principles of diagnostic ultrasonography.
Soft tissue-fluid interfaces may produce no artifact but, more commonly, there is some degree of thorough transmission artifact and far-field enhancement. This appears as increased echogenicity on the far side of the fluid.
Soft tissue-bone interfaces produce acoustic shadowing. This appears as a black area (hypoechoic) in the far-field to the interface.
NEW QUESTION # 326
What is the primary indication of the medication atipamezole?
Answer: B
Explanation:
Atipamezole is an adrenergic receptor antagonist used to reverse the effects of the alpha-2 adrenergic agonist dexmedetomidine.
Apomorphine is an emetic.
Ipratropium is a bronchodilator.
Lidocaine is a local anesthetic.

NEW QUESTION # 327
Furosemide belongs to which class of drugs?
Answer: C
Explanation:
Furosemide is a diuretic used to reduce fluid retention in patients with congestive heart failure. Other diuretics include spironolactone and hydrochlorothiazide.
Beta-blockers slow conduction signals through the heart to slow heart rhythm. Drugs in this class include atenolol and propranolol.
Calcium channel blockers also slow conduction signals through the heart to slow rhythm. Amlodipine and diltiazem are two examples of this class.
ACE inhibitors modify RAAS (renin-angiotensin-aldosterone system) and produce vasodilation. They are commonly used to treat patients with congestive heart failure or high blood pressure (hypertension). Common examples include benazepril and enalapril.
