NEW QUESTION # 1251
You are monitoring a patient under anesthesia with concerns about ventilation status. The patient has been under anesthesia for almost 3 hours at this time. Your capnograph is out for repair, and you realize you heavily relied upon it when evaluating CO2 levels in the past. However, you have an arterial catheter in place and obtain a blood gas. The CO2 levels come back significantly elevated.
This signifies which of the following conditions?
Answer: D
Explanation:
When evaluating a blood gas, the oxygen levels define a patient's oxygenating ability, while the CO2 levels depict ventilation status.
*A blood gas with elevated CO2 levels defines a patient with hypoventilation and respiratory acidosis.
*A blood gas with decreased CO2 levels is consistent with hyperventilation and respiratory alkalosis.
*The oxygenation level is not assessed by the CO2 concentration.
One can increase ventilation to a higher minute volume to treat the acidosis component caused by hypoventilation. This can be achieved by either increasing the tidal volume or respiratory rate.
Hypoventilation and anesthesia commonly occur. It can happen for any reason that causes the blood CO2 levels to drop. We commonly see hypoventilation, even apnea, during induction due to the respiratory depressant effects of many of the medications we use. It can also happen with excessive anesthetic depth, even respiratory arrest. When hypoventilation is noted, immediately inform the veterinarian, assess vital signs, check the anesthetic depth and assess additional parameters such as performing a blood gas. You may need to breathe for the patient 2 to 10 times per minute until normal respirations resume. The lower range we use when apnea is present after induction and the latter due to hyperventilation to allow the CO2 levels to normalize.
NEW QUESTION # 1252
All of the following are strengthening exercises, except:
Answer: A
Explanation:
There are numerous exercises technicians can use with animals to increase strength, endurance, balance, and/or proprioception. Sit to stand strengthens the pelvic limbs, while sit up and wave strengthens the core muscles and thoracic limbs. The balance board assists with strengthening the limbs not on the board and increases balance and proprioception of the limbs on the board.
Cavaletti poles are placed at intervals slightly above the ground horizontally and improve gait training as the animal walks over the poles. It helps improve proprioception.
NEW QUESTION # 1253
When providing pressure-assisted ventilation in a small animal patient, your manometer should not exceed what pressure?
Answer: C
Explanation:
When providing assisted ventilation, a pressure monometer helps guide you to ensure you do not overinflate the lungs. The gauge reflects the amount of pressure being applied to the patient's lungs and airways. They can measure pressure in millimeters of mercury or centimeters of water. When a patient is breathing independently, the pressure should remain at zero (0 to 2 cm H2O). The manometer is usually calibrated from - 20 to + 50 cm of H2O. The pressure is affected by oxygen flow and any pop-off valve adjustments.
The maximum reading of the manometer should never go above 20 cm H2O in a small animal (15 to 20 cm H2O, the acceptable range) and never above 40 cm of H2O in a large animal patient.
NEW QUESTION # 1254
The transport and shipping of specimens occurs daily in veterinary medicine. Which of the following should not be done when preparing and shipping a wide variety of samples to the appropriate laboratories for evaluation?
Answer: C
Explanation:
When shipping samples to an outside lab, one must ensure that the samples remain viable. Thus, most specimens benefit from refrigeration, which helps organisms stay viable. However, tests that are not looking for organisms, like some blood samples, may need to be frozen or kept at room temperature. As a general rule, it is safe to refrigerate unless told otherwise.
For any commercial carriers and outside lab pick-ups, place all samples into appropriately labeled, zip-locked bags and place them in a courier box or hand them directly to the courier.
Always label specimens with the client's name, date, pet, sample type, and the desired test. Make sure that information aligns with any paperwork that accompanies the bloodwork.
Ensure any commercial transport medium (i.e., culterettes) are adequately sealed. Some of the various containers may have a bit of liquid in them. One needs to ensure any culture tubes, blood tubes, and other samples have the lids tightly secured and are placed in an appropriate bag in case of spillage.
NEW QUESTION # 1255
Which tool is the most commonly used dental explorer in veterinary medicine, and what is it generally paired with?
Answer: A
Explanation:
A variety of dental explorers are used in veterinary medicine. They include the shepherd's hook, pigtail, or Tufts explorers, among others. However, in veterinary medicine, we often use a double-sided instrument that includes a shepherd's hook on one end and a periodontal probe.
A shepherd's hook has a sharp tip, detects caries and any fractured teeth, allows excellent tactile sensitivity, and is commonly used to detect subgingival plaque and enamel defects.
