A nurse is reinforcing teaching for a client who has a duodenal ulcer and a new prescription for sucralfate. The client asks the nurse how sucralfate works. Which of the following statements should the nurse make?
"This medication adheres to the ulcer and protects it from gastric acid”
"This medication neutralizes gastric acid after it is secreted"
This medication kills the bacteria which cause ulcers
“This medication prevents gastric acid secretion in the stomach"
The Correct Answer is A
Sucralfate works by forming a protective barrier or coating over the surface of the ulcer. It adheres to the ulcer site and provides a physical barrier that protects the ulcer from gastric acid, pepsin, and bile salts. This protective barrier allows the ulcer to heal by preventing further damage and irritation from the stomach acid.

Explanation
When reinforcing teaching with a client who has a duodenal ulcer and a new prescription for cimetidine, the nurse should include the following instructions:
"Avoid taking the medication at bedtime.": Cimetidine is most effective when taken during waking hours to help control gastric acid secretion. Taking it at bedtime may not provide optimal therapeutic benefits.
"You will need to continue taking this medication for up to 6 weeks.": Cimetidine is often prescribed for the treatment of duodenal ulcers and may require several weeks of continuous use to promote healing. It is important for the client to understand the duration of treatment and the need for adherence to the prescribed regimen.
The following statements are incorrect or not applicable:
"Drinking grapefruit juice while taking cimetidine can lead to toxicity.": Cimetidine does not have a known interaction with grapefruit juice. However, it is always important to consult the healthcare provider or pharmacist about potential drug interactions, including those related to specific foods or beverages.
"Take an antacid 30 minutes prior to taking cimetidine to minimize stomach upset.": Cimetidine is an H2 receptor antagonist that works by reducing stomach acid production. It is not necessary to take an antacid prior to taking cimetidine to minimize stomach upset. However, if the client experiences stomach upset or discomfort, they should consult their healthcare provider for further guidance on managing these symptoms.
Correct Answer is ["13"]
Explanation
To calculate the infusion rate in drops per minute (gtt/min), we can use the following formula: Infusion rate (gtt/min) = (Volume to be infused (ml) * Drop factor) / Time (min) Given:
Volume to be infused: 1,200 ml
Drop factor: 15 gtt/ml
Time: 24 hr
First, we need to convert the time from hours to minutes:
24 hr * 60 min/hr = 1,440 min
Now, we can calculate the infusion rate:
Infusion rate (gtt/min) = (1,200 ml * 15 gtt/ml) / 1,440 min
Simplifying the equation:
Infusion rate (gtt/min) = 18,000 gtt / 1,440 min
Dividing both sides:
Infusion rate (gtt/min) ≈ 12.5 gtt/min
Rounding the answer to the nearest whole number, the nurse should set the manual IV infusion to deliver approximately 13 gtt/min.
