Student #11, JM
McCurnin 10th edition, page: 879

40
Q

Student #11, JM
McCurnin 10th edition, page: 880

41
Q

What is the difference between an agonist and an antagonist?

A

An agonist is used to activate the action of an endogenous substrate at its receptor, while an antagonist is used to block the action of an endogenous substrate at its receptor.

Student #11, JM
McCurnin 10th edition, page: 881

42
Q

What is a half-life?

A

A half-life is the time needed for the amount of a drug to decrease by one half (50%) in the body.

Student #11, JM
McCurnin 10th edition, page: 881

43
Q

What routes of elimination for drugs are available in the body? What organs play a major role in drug elimination?

A

Drugs can be eliminated from the body through urine, bile, feces, expired air, milk, sweat, saliva, and tears. The kidneys and liver play a major role in drug elimination.

Student #11, JM
McCurnin 10th edition, page: 880

44
Q

What is the difference between the dosage of a drug and the drug dose?

A

Dosage is the expression of the amount of drug per body weight (e.g., mg/kg), whereas a drug dose (expressed in units) refers to the amount of the drug to be given in each administration.

Student #10, AM
McCurnin 10th edition page: 879

45
Q

What is bioavailability and which method of drug administration results in the highest level of bioavailability?

A

Bioavailability describes the drug dose fraction that reaches the bloodstream. The highest level of bioavailability (100%) is achieved through intravenous (IV) administration. This is described as a bioavailability of 1.

Student #10, AM
McCurnin 10th edition page: 880

46
Q

What is the difference between dose-dependent drug reactions and idiosyncratic drug reactions?

A

Dose-dependent drug reactions are predictable. They affect all members of a particular species and commonly affect more than one species. As the drug dose increases, so does the likelihood of these reactions. Therapeutic drug monitoring helps prevent these reactions.

Idiosyncratic drug reactions are not predictable. Only a small percentage of patients treated with the drug are affected. Multiple species may or may not be affected. Even though such reactions are not dose-dependent, increasing the dose still increases the risk of reaction. Therapeutic monitoring does not help prevent these reactions.

Student #10, AM
McCurnin 10th edition page: 881

47
Q

What causes side effects with the use of antifungal therapy?

A

If an antifungal drug targets cholesterol, which is the major sterol in mammalian cell membranes, this results in side effects (e.g., vomiting, anorexia, decreased appetite). Cholesterol is similar to ergosterol, and antifungal drugs bind to ergosterol in fungal cell membranes or inhibit its synthesis, causing the death of the cell.

Student #10, AM
McCurnin 10th edition page: 885

48
Q

What is another name for inotropic agents, and what are the two main inotropic agents used in veterinary patients?

A

Inotropic agents are also called positive inotropes. The two main positive inotropes in veterinary medicine are digoxin and pimobendan.

Student #10, AM
McCurnin 10th edition page: 889

49
Q

What is the difference between Insulin deficiency and Insulin Resistant Diabetes mellitus?

A

Insulin Deficiency requires injection of supplemental Insulin whereas Insulin Resistant Diabetes mellitus is treated with diet and activity modification.

Student #3 AF
McCurnin 10th edition page: 888

50
Q

What is Drug Compounding?

A

Defined as any manipulation of a drug other than that described on the approved drug label. This is sometimes necessary to ensure a patient gets an appropriate amount of a drug.

Student #3
McCurnin 10th edition page: 896

51
Q

What is Extra-Label Drug Use?

A

The actual use or intended use of a drug in an animal in a manner that is not in accordance with the approved labeling. Includes but is not limited to, use in a species not listed in labeling, use for indications, use at dosage levels, frequencies, or routes of administration and deviation from withdrawal time.

Student #3 AF
McCurnin 10th edition page: 895

52
Q

What are Anticoagulants used for?

A

To prevent the formation of life-threatening blood clots, or thrombi, in patients with cardiovascular disease and other systemic diseases.

Student #3 AF
McCurnin 10th edition page: 889

53
Q

What are the differences between Hypothyroidism and Hyperthyroidism and what are the drugs used to treat these diseases?

A

Hypothyroidism is a condition associated with low-circulating thyroid hormone concentrations, Levothyroxine is the drug used to treat Hypothyroidism.

Hyperthyroidism is a condition associated with high-circulating thyroid hormone concentration, Methimazole is the drug used to treat Hyperthyroidism. The administration of radio-active iodine may also treat Hyperthyroidism.

Student #3 AF
McCurin 10th edition page: 886

54
Q

What are common household measurements in mL equivalents?

A

5mL= 1 tsp
15mL= 1 tbsp

rp #9, Medical Mathematics and Calculations for Veterinary Technicians 3rd Edition, pg. 85

55
Q

what is the equation to convert a % solution into mg/ mL?

The given % will give you the grams and the 100mL will stay constant.
Examples: 5%= 5g/ 100mL
22.2%= 22.2g/ 100mL
3.3%= 3.3g/ 100mL

- Adverse Reactions

AF #2, McCurnin 10th Edition

58
Q

What is the definition of Pharmacokinetics?

A

The study of drug movement in the body (absorption, distribution, metabolism, excretion)

AF #2, McCurnin 10th Edition

59
Q

Gentamicin, Amikacin, and Neomycin are examples of drugs from which drug class? What is the mechanism of action for this class?

60
Q

Furosemide is a diuretic that acts on which part of the kidney? What is its specific action, and what are the potential side effects of this drug?

A
  • Loop of Henle (nephron)
  • Inhibits sodium/potassium/chloride reabsorption.
  • Hypokalemia, Hypochloremia, Metabolic Alkalosis

AF #2, McCurnin 10th Edition

61
Q

What is the first-pass effect?

A

Drugs that are administered orally are first transported to the liver via the portal vein, causing for many drugs to be broken down before they have a chance to be distributed to tissues. This is why certain drugs must be administered parenterally.
