Question 1 of 5
When the nurse administers a drug that stimulates the nicotinic receptors, what manifestation would indicate that the drug is working?
Correct Answer: B
Rationale: The correct answer is B: Muscle contraction. Stimulation of nicotinic receptors leads to the activation of skeletal muscles, resulting in muscle contraction. Nicotinic receptors are located at the neuromuscular junction and are responsible for the transmission of nerve impulses to the muscles, leading to muscle contraction. Pupil constriction (
A) is controlled by muscarinic receptors, not nicotinic receptors. Increase in GI motility (
C) and decrease in heart rate (
D) are mediated by other receptor types such as cholinergic receptors.
Therefore, the manifestation of muscle contraction best indicates that the drug is working to stimulate nicotinic receptors.
