NEW QUESTION # 384
You are caring for a dog with pneumonia and monitoring oxygenation status over time. Which of the following is the most accurate for assessing oxygen status?
Answer: C
Explanation:
While the most invasive, an arterial blood gas is the most accurate when measuring oxygen saturation. It involves using a placed arterial line, most commonly in the metatarsal artery, or a blood gas sample via syringe. It allows one to accurately assess the partial pressure of oxygen in the arterial blood (PaO2). When < 60 mm Hg, mechanical ventilation may be required. It also accurately assesses the partial pressure of CO2 (carbon dioxide) in arterial blood where values > 60 mm Hg may require ventilator use. The use of an arterial blood sample and blood gas evaluation best depicts the patient's oxygen status.
SaO2 represents the percentage of available hemoglobin (Hb) saturated with oxygen when measured on a blood gas.
SpO2, while less invasive, is potentially the least accurate of the options. Readings are obtained via a pulse oximeter with < 92% suggesting hypoxia. However, various factors can lead to high or low false readings, including pigmented skin/gums, human error, motion artifact, cardiac arrhythmias, and equipment malfunction. Animals with smoke inhalation and carbon monoxide (CO) exposure will not have accurate readings. It measures what is bound to hemoglobin, and CO binds more strongly to the Hb than oxygen. Since the way pulse oximetry works is simply by detecting oxygenated vs. deoxygenated Hb, it will falsely read higher than it is when carboxyhemoglobin is present.
Capnography monitors the partial pressure of CO2 & ETCO2. However, this is done by attaching to an endotracheal tube or a nasal catheter. While non-invasive in and of itself, it is most commonly performed in animals under anesthesia, on a ventilator, or who are severely debilitated. When elevated CO2 is detected, hypercarbia suggests decreased ventilation. When the value is low, it could be hypoxia, reduced ventilation, or pain.
NEW QUESTION # 385
Mandibular prognathism can also be known as which of the following?
Answer: C
Explanation:
Class I malocclusions (neutroclusion) occur when one or more teeth are in an abnormal position (misaligned). The maxilla and mandible develop in a normal relationship to each other. A Class I tooth may be pointing in the wrong direction or rotated. Common examples include rostral crossbites and linguoversion (also called base-narrow canines).
Class II-III malocclusions affect jaw length rather than tooth position alone.
Class II malocclusions (distoclusion) occur when the maxilla is forward (maxillary prognathism) and the mandible develops caudally (mandibular retrognathism). Other names include brachygnathism, overbite, and parrot mouth. These are most commonly observed in dolichocephalic dogs (long maxilla and narrow skulls).
Class III malocclusions (mesioclusion) occur when the mandible is forward (mandibular prognathism) relative to the maxilla (maxillary retrognathism). Other names include prognathism and underbite. These are commonly observed in brachycephalic dogs.
Additional malocclusions may be described, such as those created by an abnormal number of teeth in the mouth and other abnormalities that are non-specific, such as wry mouth. This simply pertains to various occlusal abnormalities that occur unilaterally.
NEW QUESTION # 386
How does a vasodilator treat heart failure?
Answer: D
Explanation:
Vasodilators treat heart failure by dilating blood vessels, allowing blood to flow forward more easily and increase vessel capacity.
Vasodilators reduce, not increase, central venous pressure and decrease, not increase, the overall workload of the heart muscle. Vasodilators do not directly reinforce the musculature of the heart.
NEW QUESTION # 387
Where is the parietal pleura found?
Answer: C
Explanation:
The parietal pleura is the membrane lining the thoracic cavity.
The visceral pleura covers the lungs and other organs within the thorax and abdomen. The space between the two is known as the pleural space. The pericardium is the membrane that covers the heart. The peritoneum is the membrane that lines the abdominal cavity.
NEW QUESTION # 388
What is a potentially significant side effect of acepromazine?
Answer: D
Explanation:
Acepromazine is a tranquilizer that blocks alpha-1 adrenergic receptors, leading to peripheral vasodilation and hypotension. This is normally manageable in otherwise healthy patients.
Acepromazine does not change intravascular volume status to cause hypovolemia, depress respiration to cause hypoxemia, or increase the respiratory rate sufficiently to cause hyperventilation. However, horses may develop tachypnea secondarily to excitement, commonly seen in the species.
