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
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.

However, there may be associations between obesity and ADHD, such as shared genetic factors or lifestyle factors, but causality is not clearly established.
C. Rheumatoid arthritis is an autoimmune disorder characterized by inflammation of the joints. While obesity is a known risk factor for osteoarthritis, particularly in weight-bearing joints, it is not typically associated with rheumatoid arthritis.
D. Hypotension, or low blood pressure, is not typically considered a complication of childhood obesity. In fact, obesity is more commonly associated with hypertension (high blood pressure) due to the increased strain on the cardiovascular system.
