46
Q

What heart valve is on the right of the ruminant?

A

Tricuspid

47
Q

What sounds should you make sure to listen for in the lungs in cattle?

A

crackles and wheezes

48
Q

What lung sounds can be normal in cattle?

A

bronchovesicular sounds

49
Q

Why is respiratory disease often mis-diagnosed in small ruminants?

A

Because their lung sounds are easier to hear than cattle

50
Q

Where is the heart located in relation to the thoracic limb in the cow?

A

It is right underneath (medial) to the crux of the elbow

51
Q

Where is the imaginary line for the caudal border of the lung field in cattle?

A

From the costochondral junction of the 6th rib to the top of the 11th rib

52
Q

Presence of rib fractures/enlargements are common in ________ following _______.

A

neonates, dystocia

53
Q

Subcutaneous ________ (lung condition) is common in the post partum cow.

A

emphysema

54
Q

A positive response to the withers pinch is a ______ and this is indicative of _______ disease.

A

grunt, hardware

55
Q

What is hardware disease?

A

When a piece of metal pierces through the reticulum and into the thoracic cavity by poking through the diaphragm

56
Q

Where should the rumen be palpated?

A

Externally in the paralumbar fossa

57
Q

What should the rumen feel like normally? In dehydrated cows?

A

Normally it feels doughy, but becomes dry/stiff with dehydration

58
Q

What should you be able to evaluate as you are palpating the rumen?

A

Rumen contractions, free gas distension, rumen fill

59
Q

What are the ‘layers’ of contents typically in the rumen?

A

From bottom to top: Sediment, liquid phase, fiber mat, and gas cap

60
Q

What should you hear when you auscultate the rumen?

A

A dull roar 1-3x per minute

61
Q

What should you be listening for when you percuss (flick) the left side of the rumen (between the 11th and 13th rib and the paralumbar fossa)?

A

Pings - not valuable in small ruminants

62
Q

What are the differentials for left sided pings?

A

Left displaced abomasum, empty gas filled rumen, free gas in the abdomen, and gas in the uterine horn

63
Q

How do you differentiate a ping if you are trying to determine if there is free gas in the abdomen?

A

Slap over the lumbar shelf with an open hand and see if that elicits a ping - the gas will rise if it is free in the abdomen so you should hear a ping

You can also ballot the abdomen to listen for sloshing or gas bubbles

64
Q

What will a displaced abomasum feel like on rectal palpation?

A

You will feel a gas filled sac around the rumen

65
Q

If you chose to pass a stomach tube and auscultate the rumen, what will you hear if it is an LDA?

A

muffled gas sounds

66
Q

Where should you auscultate on the right abdomen for intestinal motility?

A

In the caudal ventral area

67
Q

Why should you ballot during auscultation of the right abdomen?

A

To listen for liquid sloshing

68
Q

When auscultating the right abdomen, what can you hear?

A

pings and intestinal stasis

69
Q

What is an LDA associated with? A RDA?

A

LDA - early lactation

RDA - not associated with any stage of lactation or other diseases

70
Q

What increases the risk of an LDA?

A

Milk fever, ketosis, and metritis

71
Q

How can LDAs be corrected?

A

surgical and non-surgical options

72
Q

How is an LDA diagnosed?

Q

What is a RDA related to?

A

irregular feed intake and/or GI disturbances

74
Q

Is an LDA or an RDA considered emergent?

A

RDA - because of torsion

75
Q

How are RDAs diagnosed?

A

Distinctive ‘ping’ on the right side

76
Q

What should be the primary differential in any ill male small ruminant?

A

urinary obstrution

77
Q

If a male small ruminant acts constipated, what is likely the cause?

A

A urinary obstruction - this is an emergency

78
Q

What lymph nodes are externally palpable?

A

pre-scapular, pre-femoral, supramammary, parotid, submandibular, and retropharyngeal

79
Q

What lymph nodes are internally palpable?

A

Pre-iliac located cranial to the pelvis at the 4 oclock and 7 oclock positions

80
Q

What should be examined/looked for during the oral examination of the ruminant?

A

Oral erosions, ulcers, vesicles, necrosis, the dental arcade, odor, and mucous membranes

81
Q

What should you look for in the nares of the ruminant?

A

Discharges, erosions

82
Q

What should you look for in the eyes of the ruminant?

A

Compare both eyes and look for discharge, ulcers, foreign bodies, etc.

83
Q

What should the ears be evaluated for during PE of the ruminant?

A

That they are symmetrical and the temperature

84
Q

What should the neck be evaluated for during the PE of the ruminant?

A

Skin tent for dehydration, swellings/abscesses, and the jugular furrow

85
Q

What ancillary tests are often used in small and large ruminants?

A

Multistix or Ketostix, digital ketometers, iStat Blood Analyzer, California Mastitis Test (CMT), and pH assessment
