Question 1
Multiple Choice
When describing the enzyme acetylcholinesterase, which of the following would the instructor most likely include about this enzyme?
Correct!
Incorrect
The correct answer is: A,E
Rationale
Acetylcholinesterase makes the parasympathetic nervous system function differently by breaking down acetylcholine, which regulates various bodily functions. This action is crucial for maintaining balance in neurotransmission and muscular activity.
B: Inactivates the neurotransmitter serotonin. Acetylcholinesterase specifically targets acetylcholine, not serotonin, which is managed by different enzymes and pathways related to mood and cognition.
C: Activates the neurotransmitter acetylcholine. This enzyme does not activate acetylcholine; rather, it degrades the neurotransmitter to terminate its action, ensuring proper signaling in the nervous system.
D: Inactivates the neurotransmitter norepinephrine. Norepinephrine is not affected by acetylcholinesterase, as this enzyme solely acts on acetylcholine, leaving norepinephrine regulation to other mechanisms.
E: Results in the prevention of nerve synapses to continue nerve impulses. While its function impacts synaptic activity, it does not prevent synapses; it regulates neurotransmitter levels to ensure proper impulse transmission.

C: Contact the primary health care provider for an order to switch to another cholinergic drug. This action may not be necessary immediately as diarrhea is a common side effect that can often be managed effectively without changing medication.
D: Limit the client's fluid intake to 1000 mL per day. Reducing fluid intake can lead to dehydration and worsen the client’s condition, especially when diarrhea may cause increased fluid loss.
E: Maintain the client on strict bed rest. While rest is important, being confined to bed may not address the urgent need for bathroom access due to the nature of diarrhea.
Question 22
Regular
The nurse administers a prescribed oral dose of bethanechol to a client with urinary retention at 9:30 a.m. The nurse would notify the primary health care provider if the client has not voided by which time?
Correct!
Incorrect
The correct answer is: D
Rationale
The client should have voided by 11 a.m. after receiving bethanechol, as its effects typically manifest within 30 to 90 minutes. Noting this timeline is crucial for timely medical intervention if necessary.
A: 9:45 a.m. This timeframe is too short, as the medication requires more time to exert its effects and stimulate bladder activity.
B: 10 a.m. While this is somewhat reasonable, it still falls short of the usual onset period for bethanechol to facilitate urination effectively.
C: 10:30 a.m. This option is also prematurely set, not accounting for the full expected duration for the medication to initiate the desired response in bladder function.

Question 23
Regular
A client with myasthenia gravis who is prescribed pyridostigmine comes to the emergency department complaining of abdominal cramping, excessive diarrhea, and severe muscle weakness. The nurse would suspect which of the following?
Correct!
Incorrect
The correct answer is: C
Rationale
A: Cholinergic crisis
Symptoms such as abdominal cramping, diarrhea, and severe muscle weakness in this client indicate an overdose of pyridostigmine, leading to an excessive accumulation of acetylcholine, characteristic of a cholinergic crisis.
B: Underdosage of the drug
Insufficient medication would typically result in increased muscle weakness rather than gastrointestinal symptoms. The presentation suggests an adverse reaction rather than inadequate dosing.
C: Tolerance to the drug
Tolerance develops over time and would not cause acute symptoms like abdominal cramping and diarrhea. The immediate effects suggest an overdose rather than a gradual change in drug efficacy.
D: Underlying infection
While infections can cause muscle weakness, they would not directly explain the specific gastrointestinal symptoms and would present differently. The acute nature aligns more with a medication effect.

Question 24
Multiple Choice
After teaching a group of nursing students about the parasympathetic nervous system, the instructor determines that the teaching was successful when the students identify which of the following as an action?
Correct!
Incorrect
The correct answer is: B,C,E
Rationale
B, C, E: Vasodilation, increased peristalsis, and pupillary constriction exemplify actions of the parasympathetic nervous system, which promotes rest and digestion by enhancing bodily functions that conserve energy and facilitate recovery.
A: Decreased salivary gland production contradicts the parasympathetic response, which typically stimulates salivation to aid digestion and maintain oral health during restful states.
D: Bronchodilation is primarily associated with the sympathetic nervous system, which opens airways to increase oxygen intake during stress or physical activity, not during rest or relaxation.

Question 25
Regular
The students demonstrate understanding of the information when they identify that which type of receptor is involved with stimulating smooth muscle in the parasympathetic nervous system?
Correct!
Incorrect
The correct answer is: B
Rationale
Muscarinic receptors are involved with stimulating smooth muscle in the parasympathetic nervous system. These receptors mediate various physiological responses, including contraction of smooth muscle, which is essential for proper autonomic function.
A: Nicotinic These receptors primarily facilitate synaptic transmission in the somatic and autonomic nervous systems but do not directly stimulate smooth muscle contraction in the parasympathetic pathway.
C: Alpha Alpha receptors are mainly associated with the sympathetic nervous system and function in vasoconstriction and other responses, not in the stimulation of smooth muscle by the parasympathetic system.
D: Beta Beta receptors are also linked to the sympathetic nervous system, primarily influencing heart rate and bronchodilation, rather than having a direct role in stimulating smooth muscle in the parasympathetic context.
