Question 9

Mode of Action: furosemide (Lasix) - Cirrhosis Drug

Answer 9

Acts on distal tubule and loop of Henle to decrease reabsorption of sodium and water

Question 10

Mode of Action: propranolol (Inderal) - Esophageal & Gastric Varices Drug

Answer 10

Decreased BP and preload

Question 11

Mode of Action: octreotide (Sandostatin) - Esophageal & Gastric Varices Drug

Answer 11

Vasoconstricts the sphlanic bed to decrease bleeding

Question 12

Mode of Action: vasopressin (Pitressin) - Esophageal & Gastric Varices Drug

Answer 12

IV administration of VP produces vasoconstriction of the splanchnic arterial bed, decreases portal blood flow, and decreases portal hypertension

Question 13

Side effects of vasopressin

Answer 13

decreased coronary blood flow, dysrhythmias, & increased BP

Question 14

Mode of Action: IV nitroglycerin - Esophageal & Gastric Varices Drug

Answer 14

Reduces the adverse effects of vasopressin while enhancing it’s beneficial effect

Question 15

Mode of Action: Albumin - Ascites Drug

Answer 15

Adequate intravascular volume and colloid osmotic pressure

Question 16

What needs to be monitored with Albumin?

Answer 16

Vital signs, especially hemodynamics

Question 17

Answer 17

Reduces circulating volume, promote loss of excess fluid, decrease preload and afterload.

Question 18

What needs to be monitored when taking diuretic drugs?

Answer 18

electrolytes and cardiac rhythm

Question 19

Mode of Action: lactulose (laxative) - hepatic encephalopathy

Answer 19

Traps ammonia in the gut, laxative effect of the drug expels the ammonia from the colon
