Q

Hypernatremia is typically due to:

A

dehydration

Usually either inadequate water intake or pure water loss

20
Q

T/F: All causes of decreased Na+ are also causes of decreased Cl-

A

True

21
Q

What are the most common causes of hyperkalemia?

A
  • Oliguria/anuria
  • urethral obstruction
  • ruptured urinary bladder
22
Q

T/F: With hypertonic dehydration, [Na+] & [Cl-] will be decreased

A

False

With hypertonic dehydration, [Na+] & [Cl-​] will be increased

With hypotonic dehydration, [Na+] & [Cl-​] will be decreased

23
Q

For blood gas analysis, which is better for evaluating acid base status:

Venous samples or arterial samples?

A

Venous samples

24
Q

What type of blood tube would you use for blood gas analysis?

A

Heparin (Green top)

25
Q

With **High Anion Gap Acidosis, **you’ll observe an increase in nonvolatile acids. Name the nonvolatile acids:

A

KLUE

  • Ketones
  • Lactate
  • Uremic acis (phosphates, sulfates)
  • Ethylene glycol metabolites (toxins)
26
Q

Which ions are taken into consideration when calculation anion gap?

A

Na+, K+, Cl-, HCO3-

27
Q

Hyperventilation results in what acid-base abnormality?

A

Respiratory Alkalosis

“Reich at the campfire”

28
Q

What would you expect too see with regard to PTH concentration in an animal with normal parathyroid function and hypercalcemia?

A

[PTH] should be decreased

29
Q

What test would you use to differentiate Diabetes Insipidus from psychogenic polydipsia?

A

Water deprivation test

If the animal releases ADH and concentrates its urine, it is psychogenic PD. If not, it is Diabetes insipidus

DO NOT PERFORM THIS TEST IN ANY ANIMAL THAT IS:

  • Suspected of having renal disease
  • Azotemic
  • Dehydrated
30
Q

T/F: Hyperadrenocorticism is unlikely in a dog with normal urinary cortisol:creatinine ratio (UCCR)

A

True

31
Q

What is the only test that will identify iatrogenic HAC?

A

ACTH Stimulation Test

32
Q

Which of the following does not have a primary role in maintaining water balance?

  • Sodium
  • Parathyroid hormone
  • Antidiuretic hormone (vasopressin)
  • Renin
  • Aldosterone
A

Parathyroid hormone

33
Q

Which of the following would you not expect to see in a dog with pituitary-dependent hyperadrenocorticism?

  • Hypergylcemia
  • Increased alkaline phosphatase (ALP) activity
  • Increased serum cortisol concentration
  • Increased gamma glutamyl transferase (GGT) activity
  • Lymphocytosis
A

Lymphocytosis

34
Q

What is the most common cause of hyperphosphatemia?

A

Decreased glomerular filtration rate (GFR)

35
Q

What would you expect to see happen to sodium and potassium levels in an animal with aldosterone deficiency?

A

Decreased sodium, Increased potassium

36
Q

Which organ system most frequently plays a direct role in an animal developing hyperkalemia?

A

Renal system

37
Q

What is the best test to differentiate malabsorption from maldigestion in the dog?

A

Trypsin-like Immunoreactivity (TLI)

38
Q

A

False

A major crossmatch involves incubation of the donor’s erythrocytes with the patient’s serum

40
Q

If we do a low dose Dex suppression (LDDST) test on a healthy dog, what would we expect to see after 8 hours?

A

Cortisol < 1.5 μg/dL at 4 & 8 h

Cortisol secretion will decrease

41
Q

If we do a low dose Dex suppression (LDDST) test on a dog with HAC, what would we expect to see after 8 hours?

A

cortisol > 1.5 μg/dL at 8 h

Cortisol will not suppress after 8 hours

42
