A nurse is assisting with the care of four clients who have peptic ulcer disease. The nurse should identify that misoprostol (Cytotec) is contraindicated for which of the following clients?

A. This is normal.
Guaifenesin is an expectorant medication commonly used to help loosen and thin mucus in the airways, making it easier to cough up. Coughing up phlegm after taking guaifenesin is a typical and expected response to the medication. Therefore, reassuring the client that this is a normal effect of the medication is appropriate.

B. This requires further investigation: Coughing up phlegm after taking guaifenesin is a common and expected outcome, so further investigation is not necessary unless there are other concerning symptoms or indications.

C. This is indicative of an allergic reaction: Coughing up phlegm after taking guaifenesin is not indicative of an allergic reaction. Allergic reactions to guaifenesin are rare and typically present with more severe symptoms such as rash, itching, swelling, or difficulty breathing.

D. This means there is probably more pathology present: Coughing up phlegm after taking guaifenesin does not necessarily indicate the presence of additional pathology. Guaifenesin is intended to help clear mucus from the airways and is commonly used in the treatment of respiratory conditions associated with excess mucus production, such as cough due to cold or bronchitis.

A) Treatment with PPIs to decrease stomach acid:
Pancreatic insufficiency is not primarily related to excess stomach acid production, so treatment with proton pump inhibitors (PPIs) to decrease stomach acid would not address the underlying cause of the condition.

B) Treatment with stimulant laxatives:
Pancreatic insufficiency is not typically associated with constipation or the need for stimulant laxatives. While malabsorption of fats due to pancreatic insufficiency can lead to loose stools or diarrhea, treatment with laxatives is not indicated for this condition.

C) Replacement therapy with pancreatic enzymes.
Pancreatic insufficiency occurs when the pancreas does not produce enough digestive enzymes to properly digest food, leading to malabsorption of nutrients. Replacement therapy with pancreatic enzymes is the mainstay of treatment for pancreatic insufficiency. These pancreatic enzyme supplements help to replace the deficient enzymes, aiding in the digestion and absorption of nutrients from food. By taking pancreatic enzyme supplements with meals, the client can improve digestion and prevent nutritional deficiencies associated with pancreatic insufficiency.

D) Decrease food intake:
Decreasing food intake would not address the underlying cause of pancreatic insufficiency, which is the deficiency of pancreatic enzymes needed for proper digestion. In fact, decreasing food intake could exacerbate malnutrition and nutrient deficiencies in individuals with pancreatic insufficiency. The primary goal of treatment is to improve digestion and nutrient absorption by providing supplemental pancreatic enzymes with meals.
