True
Glucose absorption testing and Lactose absorption testing measure the body’s utilization of these sugars. Which one is false?

- Glucose must be digested prior to absorption in the intestines.
Both are FALSE
A simple method for obtaining a small liver biopsy sample for general hepatic diagnostics in horses and cattle is by doing:
Percutaneous needle biopsy on the right side
If a biopsy of the liver is to be obtained using laparoscopy, which type of endoscope should be selected for use?
A. Flexible fiber-optic endoscope
B. Rigid endoscope
Rigid endoscope
There are certain times where ultrasound can be beneficial in diagnosis of respiratory conditions, thoracic conditions of to confirm auscultation and percussion impressions. Two conditions that can be easily identified with ultrasound are:
Bronchopneumonia with consolidation of lung tissue
Pleural effusion
T/F
When removing or retracting the catheter that is used for a trans-tracheal wash, it is important that the catheter is removed from the trachea prior to removing the needle.
False
When susceptible cattle are kept at high elevations, pulmonary arterial hypertension can progress to congestive heart failure, with peripheral edema, venous congestion and ultimately death. The incidence of this dz can be reduced, through testing and elimination of susceptible breeding cattle from the herd, based on measurements obtained with what test?
Pulmonary Arterial Pressure test (PAP test)
What is the common name for the above pulmonary hypertensive dz when it progresses to congestive heart failure with peripheral edema?
Brisket Disease
A rancher has raised cattle at a high elevation for many years. He wants to reduce that incidence of pulmonary arterial hypertension and congestive heart failure in his herd. Strangely, he doesn’t want to spend too much money doing it. What test is recommended.
Test all of the breeding bulls
The mode used to create a two dimensional, cross sectional, real time ultrasonography video image, such as used to evaluate the carcass of a live animal, is referred to as ___ mode.
B-mode
A one dimensional vs. time video graph, as used in echocardiography, is produced using ___ mode.
M-mode
An ultrasound machine capable of displaying fluid turbulence in a vascular aneurysm, using colorization of the image is produced using ___ mode.
Doppler mode
Reproductive examinations in farm animals, such as early diagnosis of pregnancy, will utilize equipment set up to display a video using ___ mode.
B-mode
Imaging blood flow and computation of blood flow rates utilizes
Doppler mode
The culture swab that is typically used to obtain an un-contaminted culture from the uterus of large animals is called:
Tiegland culture swab
When using an ultrasound machine to diagnosis pregnancy in large animals there is a minimum number of days that should pass between the animal going out of heat or ovulating and the examination.
25 days in cattle
11 days in mares
When using an ultrasound machine to diagnosis pregnancy in horses, there is a maximum number of days that should pass if the animal is to be examined for twins. If twins are present, one of the twins may be manipulated away from the other and destroyed, in order to cause a single birth, if the exam is done prior to the day of embryo fixation. What is the max number of days that should pass to avoid embryo fixation?
15 days
During which stage of parturition is the dam most vulnerable to outside predators?
Stage 2
What is the term for the relaxation of the sacra-sciatic ligaments 24-48 hours pre-partum?
Springing
How long should a first calf heifer be in Stage 2 of parturition?
1-2 hours
What is the most common cause of dystocia in the bovine?
Calf-dam mismatch
