Which type of laxative causes peristalsis by irritating the bowel?

Stool softener

Saline/osmotic laxative

Stimulant laxative

Bulk-forming laxative

Answer and Explanation

The Correct Answer is C

A) Stool softener:
Stool softeners, such as docusate sodium, work by adding moisture to the stool, making it softer and easier to pass. They do not directly stimulate bowel movements or peristalsis through irritation of the bowel lining.

B) Saline/osmotic laxative:
Saline or osmotic laxatives, such as magnesium hydroxide (milk of magnesia) and polyethylene glycol (PEG), work by drawing water into the intestines, which softens the stool and increases bowel motility. They do not primarily act by irritating the bowel lining.

C) Stimulant laxative.
Stimulant laxatives work by directly stimulating the nerves in the intestines, which increases the rhythmic contractions of the intestines (peristalsis) and promotes bowel movements. These medications irritate the bowel lining, leading to increased motility and expulsion of stool. Examples of stimulant laxatives include bisacodyl and senna.

D) Bulk-forming laxative:
Bulk-forming laxatives, such as psyllium and methylcellulose, work by increasing the bulk and water content of the stool, which stimulates bowel movements. They do not directly irritate the bowel lining to promote peristalsis. Instead, they absorb water and swell in the intestines, creating a larger, softer stool that is easier to pass.

Explanation

To calculate the IV infusion rate in drops per minute (gtt/min), you can use the following formula:

IV infusion rate (gtt/min) =(Total volume (mL)×Drop factor (gtt/mL)) / Total time (min)

Given:

Total volume = 1000 mL

Drop factor = 10 gtt/mL

Total time = 6 hours = 6 hours × 60 minutes/hour = 360 minutes

Substitute the given values into the formula:

IV infusion rate (gtt/min) = (1000mL×10gtt/mL)/360 min

IV infusion rate (gtt/min) = 10,000/360

IV infusion rate (gtt/min)≈27.78gtt/min

Rounding to the nearest whole number, the IV infusion rate is approximately 28 gtt/min

A. Take as needed for pain relief. B. Take the medication 1 hr before meals. C. Store the medication in the refrigerator. D. Take the medication with an antacid

Correct Answer is B

Explanation

A) Take as needed for pain relief.
Sucralfate is not used as an as-needed medication for pain relief. It is a gastroprotective medication that is typically taken regularly as prescribed, regardless of whether the client is experiencing pain.

B) Take the medication 1 hr before meals.
Sucralfate is a medication commonly used to treat peptic ulcer disease by forming a protective barrier over the ulcer, promoting healing and symptom relief. It should be taken on an empty stomach, at least 1 hour before meals, and at bedtime to maximize its effectiveness. Taking sucralfate before meals ensures that the medication can coat the ulcer and provide protection against gastric acid during digestion.

C) Store the medication in the refrigerator.
Sucralfate does not need to be stored in the refrigerator. It should be stored at room temperature away from moisture and heat, according to the manufacturer's instructions.

D) Take the medication with an antacid.
Sucralfate should not be taken with antacids because antacids can interfere with its effectiveness. Antacids can decrease the absorption of sucralfate, so it is important to separate the administration of sucralfate from antacids by at least 30 minutes to 1 hour.
