Question

Following administration of a dose of atropine to your patient, which of the following effects are not likely to occur?

A. Dry mouth
B. Decreased mucus production
C. Bronchial constriction
D. Increased heart rate

Answer 1

After administering atropine, bronchial constriction is not likely to occur; instead, bronchial dilation is expected, along with dry mouth, decreased mucus production, and increased heart rate due to its anticholinergic effects.

Step-by-step explanation:

Following the administration of atropine to a patient, the effect that is not likely to occur is C. Bronchial constriction. Atropine is an anticholinergic drug, which means it acts as an antagonist to muscarinic acetylcholine receptors. This blocks the effects of acetylcholine and typically results in bronchial dilation, rather than constriction. On the other hand, expected effects of atropine include A. Dry mouth and B. Decreased mucus production because it inhibits the secretions of various glands. Additionally, atropine is known to cause D. Increased heart rate by inhibiting the vagus nerve, which normally decreases heart rate.
