Q

Used to prevent or delay the clotting of blood; example: Heparin sodium and warfin (Coumadin)

A

Anticoagulants

39

Oral anticoagulant that interferes with synthesis of prothrombin in the liver, used to prevent clots, latent period of 24 hours and residual for several days; generally discontinued prior to surgery or treated with its antidote vitamin K (Mephyton, Aqua Mephyton)

A

Warfarin (Coumadin)

40
Q

Used to prevent or counteract an allergic reaction example: Diphenhydramine (Benadryl)

A

Antihistamines

41
Q

Used to increase urinary output and control edema and hypertension; use in neurosurgery and ophthalmic surgery examples furosemide and mannitol

A

Diuretics

42
Q

Used to enhance visualization of a structure or for marking skin incisions; examples methylene blue, indigo carmine, brilliant green, and gentian violet

A

Dyes

43
Q

Used to control bleeding in surgery; examples thrombin, bone wax, absorbable gelatin sponge (Gelfoam), oxidized cellulose (Oxycel, Surgicel), microfibrillar collagen (Avitene), absorbable collagen sponge, and protagonist sulfate

A

Hemostatic agents (Coagulants)

44
Q

Given IV to counteract the effects of heparin

A

Protamine sulfate

45
Q

Used to promote utilization of glucose to treat diabetes

A

Insulin

46
Q

Used to antagonize insulin or treat hypoglycemia

A

Glucagon

47
Q

Used to identify abnormal tissue usually iodine based examples: Schiller’s test (uses Lugols solution) and Lugol’s solution for identifying abnormal cervical cells prior to biopsy

A

Stains

48
Q

Used to constrict blood vessels to raise blood pressure examples vasopressor (Pitressin) and norepinephrine (Levophed)

A

Vasopressor

49
Q

This blue injection is used to test how well the lymphatic system is working in certain parts of the body. It works by staining the lymph nodes and lymph vessels, such as the sentinel node.

57
Q

Why is the use of indigo carmine useful in bladder/kidney function tests?

A

This allows immediate identification of possible leaks or damage to the ureters or bladder, as well as demonstration of kidney function.

58
Q

This staining agent performs a Schilller’s test on cervical tissue which stains normal cells brown to detect cervical dysplasia.

A

Lugol’s solution

59
Q

most commonly used agent in loop diuretics, very useful for intracranial procedures. It decreases pressure by quickly removing fluid that forms from a trauma. thiazide diuretic treats hypertension and chronic edema by inhibiting sodium and chloride from being reabsorbed in the nephron

A

Furosemide (Lasix)
