The provider has ordered intramuscular (IM) injections of morphine, a narcotic, every 4 hours as needed for pain in a motor vehicle accident victim.
The nurse is aware this drug has a high abuse potential.
Under what category would morphine be classified?
Schedule I.
Schedule III.
Schedule IV.
Schedule II.
The Correct Answer is D
Choice A rationale
Schedule I drugs have no medical use and high abuse potential, unlike morphine.
Choice B rationale
Schedule III drugs have less abuse potential than Schedule II, making this incorrect for morphine.
Choice C rationale
Schedule IV drugs have even lower abuse potential, incorrect for morphine.
Choice D rationale
Schedule II drugs have high abuse potential with medical use, fitting morphine's classification.

Correct Answer is B
Explanation
Choice A rationale
Cholinergic agonists primarily stimulate the parasympathetic nervous system rather than the central nervous system, affecting activities like digestion, salivation, and decreased heart rate.
Choice B rationale
Parasympathetic nervous system is the correct answer. Cholinergic agonists mimic acetylcholine and stimulate parasympathetic responses, promoting rest-and-digest functions such as reducing heart rate and enhancing glandular secretions.
Choice C rationale
The sympathetic nervous system is not stimulated by cholinergic agonists. Instead, this system is activated by adrenergic agonists, which prepare the body for fight-or-flight responses, increasing heart rate and blood pressure.
Choice D rationale
Voluntary nervous system control is not the primary target of cholinergic agonists. This system governs skeletal muscle movement and is influenced by neuromuscular junctions rather than the autonomic responses modulated by cholinergic drugs. .
Correct Answer is D
Explanation
Choice A rationale
The auricle is an ear-shaped appendage on the surface of the atrium and does not separate the right and left halves of the heart. Its function is to increase the capacity of the atrium, allowing for more blood to be collected and passed to the ventricles.
Choice B rationale
Syncytia refer to a multinucleated cell that can result from the fusion of multiple cells, which is not a structure that separates the right and left sides of the heart. They are typically related to muscle tissue and coordinated contractions.
Choice C rationale
The Bundle of His is a collection of heart muscle cells specialized for electrical conduction that transmits the electrical impulses from the AV node to the point of the apex of the fascicular branches. It does not act as a separator between the right and left halves of the heart.
Choice D rationale
The septum is the structure that separates the right and left halves of the heart. It is a robust wall that divides the atria (interatrial septum) and the ventricles (interventricular septum), ensuring the segregation of oxygenated and deoxygenated blood.
