Which is an important teaching point for the nurse to make to a client taking a bulk- forming laxative?
"Reduce the fiber in your diet."
"This medication will make you drowsy."
"Drink plenty of fluid while taking this."
"This laxative can be addictive."
The Correct Answer is C
A. "Reduce the fiber in your diet.": Bulk-forming laxatives, such as psyllium, work similarly to dietary fiber by absorbing water and increasing stool bulk. Reducing dietary fiber would counteract the intended therapeutic effect and is not advised during treatment.
B. "This medication will make you drowsy.": Bulk-forming laxatives do not have central nervous system effects and are not associated with sedation or drowsiness. This side effect is more relevant for medications like antihistamines or opioid analgesics.
C. "Drink plenty of fluid while taking this.": Adequate fluid intake is essential when using bulk-forming laxatives to prevent intestinal obstruction. Water helps the fiber expand and form a soft, bulky stool, which promotes effective and safe bowel movements.
D. "This laxative can be addictive.": Unlike stimulant laxatives, bulk-forming agents do not cause dependency or lead to laxative abuse. They are safe for long-term use when taken with sufficient water and proper diet.

Explanation
Desired dose per administration = 20 mg.
- Determine the number of administrations in 24 hours.
"twice a day," which means 2 administrations in 24 hours.
- Calculate the total milligrams administered in 24 hours.
Total mg in 24 hours = 20 mg/dose × 2 doses/day
= 40 mg/day.
Available concentration = 40 mg/5 mL.
- Calculate the total milliliters to be given in 24 hours.
Volume (mL) = Total mg in 24 hours / (Available concentration (mg) / Available volume (mL))
= 40 mg / (40 mg / 5 mL)
= 40 mg / 8 mg/mL
= 5 mL.
Correct Answer is ["A","C","E"]
Explanation
A. PPIs cannot be crushed: Proton pump inhibitors are often enteric-coated to prevent degradation by stomach acid and ensure proper absorption in the small intestine. Crushing them disrupts this protective coating, reducing effectiveness and possibly leading to gastrointestinal irritation.
B. Famotidine is a common proton pump inhibitor: Famotidine is not a PPI but an H2-receptor antagonist. While both drug classes reduce gastric acid secretion, they work via different mechanisms and are not interchangeable in classification or pharmacological action.
C. Given to treat gastric ulcers: PPIs are commonly prescribed for gastric ulcers due to their potent acid suppression, which promotes mucosal healing. By inhibiting the H+/K+ ATPase enzyme in gastric parietal cells, they effectively reduce acid levels and facilitate ulcer recovery.
D. You can take PPIs daily indefinitely: Long-term daily use of PPIs is not recommended due to risks such as nutrient malabsorption, bone fractures, and increased susceptibility to infections like C. difficile. They should be used for the shortest effective duration, with regular reassessment.
E. PPIs have numerous adverse effects: Adverse effects associated with PPIs include headaches, diarrhea, vitamin B12 deficiency, hypomagnesemia, and increased risk of osteoporosis-related fractures.
