A nurse is reviewing the medical history of a client who has myasthenia gravis and is asking about starting neostigmine. The nurse should identify which of the following client conditions as a potential contraindication for cholinesterase inhibitor therapy?
Cataracts
Hypertension
Hypothyroidism
Peptic ulcer disease
The Correct Answer is D
Rationale:
A. Cataracts are not a contraindication for cholinesterase inhibitors like neostigmine.
B. Hypertension is not a direct contraindication for cholinesterase inhibitor therapy, although caution may be exercised depending on the overall health status of the client.
C. Hypothyroidism is not contraindicated for cholinesterase inhibitors; however, it should be managed appropriately.
D. Peptic ulcer disease is a significant contraindication for cholinesterase inhibitors like neostigmine because these medications can increase gastric secretions and motility, potentially exacerbating ulcer conditions and leading to complications.

Correct Answer is A
Explanation
Rationale:
A. The pharmacist typically restocks the medication drawer each day to ensure that medications are available and up-to-date. This is an essential component of the unit-dose medication system.
B. The nursing supervisor does not usually unlock the medication drawer; this is typically done by the nurse in charge or the individual administering the medications.
C. While it is important to limit the number of controlled substances, the medication drawer is usually stocked in a manner that allows for easy access to necessary medications, and there are regulations that govern this process.
D. Opened medications should not necessarily be disposed of at the end of each shift; they may be retained if they are still within their stability period and are properly stored according to protocols.
Correct Answer is B
Explanation
Rationale:
A. A decrease in the amount of gastric acid production: Alosetron is not used to decrease gastric acid production. This effect is more associated with medications such as proton pump inhibitors or H2 blockers.
B. A decrease in the frequency of defecation: Alosetron is used to treat irritable bowel syndrome with diarrhea (IBS-D) by reducing bowel movement frequency and improving stool consistency.
C. An increase in gastric motility: Alosetron works by decreasing intestinal motility, which helps reduce diarrhea, not by increasing it.
D. An increase in the absorption of water into the intestine: Alosetron does not specifically increase water absorption into the intestine. Its primary effect is slowing intestinal transit to reduce diarrhea.
