Answer
-
no thyroid hormone precursors T1 or T2 can be produced.
-
to many thyroid hormone precursors T1 or T2 are produced.
-

-
Inhibin/Estrogen
-
Do not produce hormones
Question 13

Answer
-
released by the pituitary.
-
which have LH like effects.
-
are produced by the Dam’s uterus.
-
are the same as gonadorelins.
Question 14
Question
Progesterone has a negative feedback effect on the release of all except
Answer
-
FSH
-
LH
-
GnRH
-
estrogen
Question 15
Question
Prostaglandins are commonly used to terminate pregnancies in many domestic species. Injection of the specific prostaglandin F2-alpha (PgF2-alpha) is alone not 100% effective in causing parturition in cattle that are near term. Why?
Answer
-
PgF2-alpha is a prostaglandin that functions as a gastroprotectant
-
PgF2-alpha is not labeled for use in food animals
-
PgF2-alpha doesn’t exert an influence on the uterus
-
PgF2-alpha doesn’t exert an influence on the corpus luteum
Question 16
Question
Of the following list, who should be chosen to administer prostaglandin for estrous synchronization of dairy cows on a farm?
Answer
-
The farmer who is 6 months pregnant
-
The farmer’s son who is an asthmatic
-
The farm hand who forgot her gloves in her truck
-
The healthy technician who is used to handling needles and syringes
Question 17
Question
What is the hormone that promotes the maintenance of pregnancies?
Answer
-
Oxytocin
-
Prostaglandin
-
Progesterone
-
Prolactin
-
Relaxin
Question 18
Question
What would be the effect of using a U-40 syringe instead of a U-100 syringe to pull up a dose of insulin?
Answer
-
No effect—they are the same syringe, just marketed differently
-
Insulin react s adversely with the syringe materials if the drugs are mismatched
-
The dose will likely be incorrect, leading to possible dangerous side effects
-
It’s not possible, as the bottles require specific syringes to draw up the drug
Question 19
Question
Which type of injectable insulin product should be used during a diabetic emergency, administered via the IV route?
Answer
-
PZI (protamine zinc insulin)
-
Regular insulin
-
NPH (neutral protamine Hagedorn insulin)
-
Insulin glargine
Question 20
Question
A farmer has a cow that has experienced chronic ketosis over the period of 2 months. The herd veterinarian diagnoses fatty liver syndrome, a condition where over conditioned cattle deposit excess lipid in their liver parenchyma resulting in a metabolic disorder which effects the body’s utilization of blood sugar. In addition to the standard ketosis treatment of IV glucose, dexamethasone, and B vitamins, the veterinarian adds BID insulin to the protocol for 3 days. Why is this addition contraindicated in this scenario?
Answer
-
Because cattle don’t respond to insulin
-
Insulin receptors won’t react to the insulin
-
Insulin is too expensive to be reliably used in farm practice
-
There is no problem with this protocol
Question 21
Question
Why would a cat with hyperthyroidism as well as blood calcium imbalances benefit from treatment with radioactive iodine in place of surgical thyroidectomy?
Answer
-
Need to spare the parathyroid glands
-
This is obviously an old cat, which would not be suitable for a major surgery
-
Thyroidectomy isn’t 100% curative for hyperthyroidism
-
Radioactive iodine can be given at home by the pet’s owners
Question 22
Question
Endocrine hormones function to not only affect a target tissue, but to cause a subsequent decrease in the continued release of more of the same hormone. This mechanism that limits the amount of a hormone response that occurs is called:
Answer
-
tolerance.
-
upregulation.
-
negative feedback.
-
resistance.
-
positive stimulus.
Question 23
Question
Concerning the cascade responsible for the production of thyroid hormone, first a _______________ hormone is produced from the hypothalamus, which acts on the anterior pituitary to produce a ________________ hormone that function to cause the thyroid gland to produce the final hormone in the cascade, thyroxine.
Answer
-
primary, secondary
-
stimulating, controlling
-
positive, negative
-
releasing, stimulating
Question 24
Question
Why is levothyroxine (T4) preferred for treatment of hypothyroidism than liothyronine (T3)?
Answer
-
T3 is a synthetic drug, while T4 is natural
-
T3 is never used in clinical cases
-
T4 is much cheaper than T3
-
T4 has a much shorter half-life than T3, so it’s potentially more toxic
-
T4 appears more of a factor in the negative feedback loop than T3
Question 25
Question
What is the euthyroid state?
Answer
-
Abnormal thyroid levels that occur with disease
-
Euthanasia of an animal with a primary thyroid tumor
