What adverse reaction(s) woul be commonly noted with the use of a cholinergic blocking drug
- A.
Blurred vision
- B.
Dry mouth
- C.
Gi upset
- D.
All the above
Correct Answer
D. All the aboveExplanation
The use of a cholinergic blocking drug commonly results in adverse reactions such as blurred vision, dry mouth, and gastrointestinal upset. These effects occur because cholinergic blocking drugs inhibit the action of acetylcholine, a neurotransmitter responsible for various bodily functions. Blurred vision occurs due to the drug's impact on the muscles controlling the shape of the lens in the eye. Dry mouth is a result of reduced saliva production caused by the drug's interference with acetylcholine's role in salivary gland function. GI upset can occur due to the drug's impact on the digestive system, leading to symptoms like nausea, vomiting, and abdominal discomfort.Rate this question:
