Prior to administration of the initial dose of the gastrointestinal (GI) agent misoprostol, which information should the nurse obtain from the patient?

A. Phosphate: Calcium acetate is used primarily to manage hyperphosphatemia in patients with chronic kidney disease (CKD). It works by binding to dietary phosphate in the gut, preventing its absorption, which helps lower phosphate levels in the blood. A decrease in phosphate levels indicates that the calcium acetate is effectively controlling phosphate levels.
B. pH: While maintaining normal pH levels is important in CKD, calcium acetate does not directly affect blood pH. The primary role of calcium acetate is to manage phosphate levels rather than pH balance.
C. Calcium: Calcium acetate is a phosphate binder and does not primarily target calcium levels. It can influence calcium levels indirectly, but a decrease in calcium is not the direct measure of the medication's effectiveness. Instead, monitoring phosphate levels is more indicative of the medication’s effectiveness.
D. Potassium: Calcium acetate does not have a direct effect on potassium levels. It is specifically used to manage phosphate levels in CKD patients. Changes in potassium levels would not indicate the effectiveness of calcium acetate.

A. I should use this medication in its hand inhaler every day.: Tiotropium is a long-acting anticholinergic medication used for managing COPD, and it should be used daily, even if symptoms are not present. This statement indicates that the client understands the need for consistent daily use of the medication to manage COPD effectively.
B. When I cough up sputum, the secretions should be less thick.: Tiotropium is not specifically aimed at changing the thickness of sputum. It primarily works to open the airways, so while it may help with overall symptoms, it doesn't directly affect sputum viscosity.
C. I will use my other inhaler in between uses.: Tiotropium is usually prescribed for regular use as part of a long-term management plan, and the client may have other inhalers for different purposes (e.g., rescue inhalers for acute symptoms). However, the statement about using another inhaler in between uses may not be specific to the proper use of tiotropium itself.
D. If I have sudden shortness of breath, I will use this inhaler.: Tiotropium is a long-acting inhaled medication meant for maintenance therapy and is not intended for immediate relief of acute symptoms. For sudden shortness of breath, a rescue inhaler (usually containing a short-acting bronchodilator) would be more appropriate.
