NEW QUESTION # 810
Which monitoring parameter best assesses ventilation?
Answer: B
Explanation:
Capnography is a good monitoring tool for ventilation under anesthesia. It provides continuous information on inhaled and exhaled carbon dioxide, respiratory rate, and breathing pattern. Other indicators of ventilation used to assess anesthetized patients are respiratory rate, respiratory effort, and blood gas analysis.
Pulse oximetry indicates oxygenation, though not always reliable. For example, if the patient has pigmented mucous membranes, the reading may not be reliable. Blood pressure and pulse strength are indicators of circulation.
NEW QUESTION # 811
Which of the following is not appropriate use of a dental explorer?
Answer: A
Explanation:
A dental explorer is a thin metal instrument with a curved "Shepherd's hook" and sharp tip at the working end. The tip is gently moved along tooth surface to detect irregularities, such as subgingival calculus and enamel defects. The tip can be applied to the fractured surface of a tooth under moderate pressure to check for soft areas that may indicate an opening into the pulp chamber. Either the tip or the hook can be placed on a crown to assess for mobility with either a pushing or pulling motion.
An explorer should not be used to measure gingival sulcus depth because the sharp tip can traumatize gingiva. Additionally, there are no millimeter markings to objectively evaluate depth. Instead, a periodontal probe with smooth sides, a blunt tip, and measurement markings should be used.

NEW QUESTION # 812
Which of the following is most commonly used for the induction of anesthesia in avian patients?
Answer: C
Explanation:
Inhalants, such as isoflurane and sevoflurane, combined with oxygen, are most commonly used for anesthetic inductions in avian patients.
Prior to induction, patients should be premeditated with a sedative to prevent stress prior to induction. Gas induction without pain medication and sedation is extremely anxiety-inducing and against medical advice. Commonly, avian patients will receive anti-anxiety medications such as a benzodiazepine like midazolam and a pain med/sedative like butorphanol. Other sedatives used in mammalian species, such as dexmedetomidine, are not currently recommended for use in birds, due to cardiac side effects and lack of scientific evidence-based support for their use.
The recommended protocol for gas induction is to preoxygenate avian patients for 2 to 5 minutes, then slowly increase the inhalant concentration until an appropriate anesthetic plane is reached and intubation can occur with ease.
Both butorphanol, while a great sedative with mild analgesic properties, and midazolam, an anti-anxiety medication, would not be sufficient alone to induce an anesthetic plane. Dexmedetomidine, as stated above, is contraindicated in the species.
NEW QUESTION # 813
A farmer wants to treat his cattle herd with ivermectin pour-on. Your hospital stocks 1L bottles in a 5 mg/mL concentration. The dose is 1 mL per 22 pounds body weight. His cattle average 550 pounds each.
How many cattle will one bottle treat?
Answer: D
Explanation:
Calculate how much one animal will need: 550 pounds x (1 mL/22 pounds) = 25 mL/animal Calculate how many 25 mL doses are in a 1 liter bottle (1000 mL): (1000 mL/bottle) / (25 mL/dose) = 40 doses
NEW QUESTION # 814
A stallion is being sedated for oral evaluation as he's been chewing only on one side. You are working with a vet you haven't worked with previously, and they have selected xylazine as a sedative. You administer it and wait until it takes effect. You are unfamiliar with it versus the other alpha-2 agonist, detomidine, that other vets use. When holding an animal for oral evaluation-even one that has been sedated-you need to be very mindful of their behavioral cues to prevent injury to you and the veterinarian.
In addition to the respiratory and cardiovascular effects commonly seen with this drug class, what is one thing to be wary of with drugs like xylazine more than with detomidine?
Answer: B
Explanation:
Alpha-2 agonists like detomidine and xylazine are commonly used for standing sedation or as part of a mixed protocol for field or complete anesthesia. For standing sedation, as discussed here, either drug may be used to permit an oral exam.
Both can cause:
*Drooling
*Increased blood pressure
*Low heart rates
*Muscle tremors
*Piloerection
*Respiratory suppression
*Sweating
The doses used dictate the degree of sedation. With lower doses, animals will simply lower their heads as they relax. In comparison, with higher doses, they may become fully recumbent.
Xylazine causes a less profound decrease in heart rate and is less likely to cause bradyarrhythmias like AV block. However, xylazine aggression can happen, especially in a stallion, and behavior can be extremely unpredictable during the breeding season. This aggression doesn't tend to occur with detomidine.
Keep in mind that animals will be potentially hyperreactive to sound with both drugs, so take steps to minimize auditory triggers. Cover their eyes to minimize light and sensory input, and use caution when moving around the animals. Be mindful of the kick zone and always remain alert when restraining an animal, regardless of the sedative used. As with both drugs (and others), horses may seem very sedate but can still kick with adept accuracy.
