The nurse is caring for a client newly diagnosed with gastroesophageal reflux disease (GERD). The client complains to the nurse of severe burning in the esophagus. The provider orders magnesium hydroxide. What outcome should the nurse expect if the medication achieves the desired therapeutic effect?

Neutralized gastric acid

Reduced stomach motility

Reduced duodenal pH

An increased barrier to pepsin

Answer and Explanation

The Correct Answer is A

A.   Magnesium hydroxide is an antacid medication that works by neutralizing gastric acid in the stomach. Therefore, if the medication achieves the desired therapeutic effect, the nurse should expect neutralization of gastric acid, which can alleviate the burning sensation in the esophagus associated with GERD.
B.   Magnesium hydroxide does not directly affect stomach motility. Instead, its primary action is to neutralize gastric acid. Therefore, reducing stomach motility is not an expected outcome of magnesium hydroxide administration.
C.   Magnesium hydroxide primarily acts within the stomach to neutralize gastric acid and does not significantly affect the pH of the duodenum. Therefore, reduced duodenal pH is not an expected outcome of magnesium hydroxide administration.
D.   Pepsin is an enzyme involved in the digestion of proteins and can contribute to tissue damage if refluxed into the esophagus. Although reducing gastric acidity can indirectly decrease the activity of pepsin, magnesium hydroxide does not directly increase the barrier to pepsin.

Correct Answer is A

Explanation

A. Teach the client to support the surgical site while deep breathing and coughing: This action is appropriate as it helps prevent complications such as atelectasis and pneumonia by promoting lung expansion and clearing secretions. Supporting the surgical site while deep breathing and coughing helps reduce pain and discomfort during these activities.
B. This is an important teaching point for clients using PCA for pain control after surgery. Opioid medications used in PCA can lead to gastrointestinal motility issues, including constipation. However, pain management is central within the first 24 hours post operation.
C. Irrigating and repositioning the NGT frequently can increase the risk of complications such as displacement or irritation of the surgical site. NGT care should be performed as needed based on institutional protocols and the client's condition.

D. The client's diet will likely be advanced gradually, starting with clear fluids and progressing to full liquids and then solid foods as tolerated. Fruit juices may be introduced gradually as part of the liquid diet once the client's gastrointestinal function has recovered sufficiently.

A. "I'm so glad I will be able to drink orange juice while I'm taking these medications." B. "While I'm taking these medications, my bowel movements could be black." C. "I'll include more calcium and vitamin D in my diet to prevent osteoporosis." D. "I have a medicine at home to take when I start having loose stools."

Correct Answer is B

Explanation

B. Bismuth subsalicylate, one of the medications prescribed for peptic ulcers, can cause blackening of the stools. This discoloration is harmless and temporary but is an important side effect to be aware of.
A. Citrus juices, including orange juice, can exacerbate symptoms of peptic ulcers due to their acidic nature. Therefore, it would not be appropriate for the client to consume orange juice while taking famotidine and bismuth subsalicylate.
C. Osteoporosis is not a known side effect or concern associated with these medications.
D. Constipation and not diarrhea, is a potential side effect of bismuth subsalicylate.
