Accepted Answer

The term for hairless neonates used as feeders is "pinkies," making option B the correct choice. The other options, "baldies," "hoppers," and "fuzzies," are not terms used to describe hairless neonates used as feeders.

Question 2

If rodents run out of water, they have been known to _____.&#10;A)cannibalize one another&#10;B)estivate&#10;C)eat their own feces&#10;D)self-mutilate

Accepted Answer

When rodents run out of water, they may resort to cannibalism as a means of survival, especially if there is no other food source or water available. This behavior has been observed in various species of rodents in laboratory and natural settings. Estivation is a state of dormancy that some animals enter during periods of extreme heat or drought, but rodents are not known to estivate. Eating their own feces (coprophagy) is a common behavior in some rodents, but it is not directly related to water scarcity. Self-mutilation is a rare behavior in rodents and is typically observed in laboratory settings under highly stressful conditions.

Question 3

The best choice for blood collection in a rat or mouse is _____.&#10;A)a warmed lateral tail vein&#10;B)the lateral saphenous vein&#10;C)the orbital sinus&#10;D)the jugular vein

Accepted Answer

The warmed lateral tail vein is commonly used for blood collection in rats and mice as it is less invasive and causes minimal stress to the animal compared to other methods.

Question 4

Rodents rarely survive _____.&#10;A)Upper respiratory infections&#10;B)Otitis interna&#10;C)Tyzzer's disease&#10;D)Abscesses from fighting

Accepted Answer

Tyzzer's disease is a deadly bacterial infection that affects rodents, particularly mice and is the most likely to be fatal. Upper respiratory infections, otitis interna, and abscesses can also be serious health problems for rodents but may not always result in death if treated in time.

Question 5

How much fluid can be given SQ or IP to a rat for fluid therapy?&#10;A)Approximately 10 ml&#10;B)Up to 5 ml&#10;C)Roughly 25 ml&#10;D)No more than 2 ml

Accepted Answer

SQ (subcutaneous) or IP (intraperitoneal) fluid therapy is typically limited to no more than 5 ml in rats. Giving too much fluid can lead to fluid overload or even rupture of the peritoneal membrane in IP administration. The fluid amount must be based on the weight of the rat and the recommendation of a veterinarian.

Question 6

Accepted Answer

Male rats are generally considered to be more docile and friendly than female rats. Female rats may be more active and independent, which can make them less prone to cuddling or sitting still for extended periods. However, all rats can be socialized and become great pets with proper care and attention.

Question 7

Which of the following is by far the most prevalent problem found in both rats and mice?&#10;A)Barbering&#10;B)URIs&#10;C)Inner ear infections&#10;D)Tumors

Accepted Answer

Tumors are by far the most prevalent problem found in both rats and mice, with a high incidence rate especially as these animals age.

Question 8

The effect is synchronization of reproductive cycles in females.&#10;A)Bruce&#10;B)Whitten&#10;C)Bruxism&#10;D)Whelp

Accepted Answer

The Whitten effect refers to the synchronization of reproductive cycles in females, particularly in rodents, due to pheromone cues emitted by males. Bruce is a male given name, bruxism is a condition of involuntary teeth grinding, and whelp refers to a young offspring of certain mammals such as dogs or wolves.

Question 9

The Latin term rodere means _____.&#10;A)to adapt&#10;B)filth&#10;C)villain&#10;D)to gnaw
