Bulk Forming and Surfactant
This bulk-forming laxative works like dietary fiber to soften stool and increase bulk
Psyllium
Magnesium hydroxide draws water into the intestine to stimulate this
Peristalsis
This drug increases the excretion of potassium via the GI tract
Sodium polystyrene sulfonate
This antidiarrheal drug is a combination of opioid and anticholinergic agents
Diphenoxylate with atropine
Ferrous sulfate turns stools this color
Black or dark green
Surfactant laxatives lower this to allow water to penetrate stool
Surface tension
High doses of magnesium hydroxide are used for this purpose
Bowel prep before surgery of diagnostics tests
Sodium polystyrene is indicated for this condition
Hyperkalemia
Diphenoxylate with atropine works by activating these receptors in the GI tract
Opioid receptors
Ferrous sulfate should be taken with or without food for best absorption?
Without food (Food decreases absorption)
A major adverse effect of a bulk-forming laxative if not taken with enough fluid
Obstruction
Bisacodyl
Laxatives are contraindicated in clients with fecal impaction, bowel obstruction, and this acute condition
Acute surgical abdomen
Correct patient statement when using diphenoxylate with atropine
"As my stools decrease, I will discontinue this medication"
Folic acid is essential for this process involving RBCs WBCs and platelets
Erythropoiesis and DNA synthesis
Docusate Sodium is primarily used for these two indications
Treatment of constipation and softening fecal impaction
Common adverse effects of bisacodyl suppository use
Rectal burning
Routine use of laxatives should be avoided; they should only be used in what way?
PRN/ SHORT TERM
Metoclopramide increases GI motility and blocks these two receptors in the CTZ
Dopamine and Serotonin Receptors
Two high risk groups who need folic acid supplementation
Pregnant women and people with alcohol use disorder
True or False?
Patients can take psyllium or docusate sodium without water
FALSE
Take with a full glass of water
Clients with renal failure should avoid this osmotic laxative
Magnesium hydroxide
Two goals showing therapeutic effectiveness of laxatives
Relief of constipation and bowel evacuation before surgery
A dangerous long-term adverse effect of metoclopramide
Tardive dyskinesia
Foods high in folic acid include
Leafy greens, citrus fruits, legumes (beans and lentils)
