Question 1

The nurse is instructing a client on the characteristics of central nervous system medications.Which characteristic should be included in this teaching?

Accepted Answer

Central nervous system medications must be able to cross the blood-brain barrier in order to affect the brain and nervous system. Neurotransmitters, the function of a neuron, and the location of synapses are all important concepts related to the central nervous system, but they do not necessarily describe the characteristics of medications that are used to treat conditions affecting this system.

Question 2

A client is prescribed medication to treat bipolar disorder.Which statement indicates the client understands the medication regimen?

Accepted Answer

Option C indicates that the client understands that the medication is intended to help with their symptoms, which is an appropriate expectation. Option A is incorrect as there is currently no cure for bipolar disorder. Option B is not appropriate as the medication regimen should be taken consistently as prescribed. Option D is also incorrect as there are usually several medication options to treat bipolar disorder, and the specific medication prescribed may depend on individual factors such as the client's medical history and symptoms.

Question 3

The family of a client who has a tumor deep in the brain is concerned about the client's demonstration of aggression and anger over the last few months.Which response by the nurse is the most appropriate?

Accepted Answer

The nurse should educate the family that the tumor may be affecting areas of the brain responsible for emotional expression. This can cause the client to present with symptoms of irritability, aggression, and anger. It is important to provide education and support to both the client and family, as this can be a difficult and distressing time for all involved. Referral for anger management may be appropriate, but the root cause of the behavior should be addressed first. Informing the healthcare provider is also important, but educating the family should be the nurse's first priority. The nurse should not label the client's response as abnormal, as this can be distressing for both the client and family.

Question 4

A client newly diagnosed with depression is given a prescription for an antidepressant.The nurse understands that the medication prescribed affects which neurotransmitter that is associated with anxiety,impulsive behavior,and suicidal ideation?

Accepted Answer

Serotonin is a neurotransmitter that plays a role in regulating mood, anxiety, impulsivity, and suicidal ideation. Antidepressants work by increasing the levels of serotonin in the brain, which can help alleviate the symptoms of depression.

Question 5

The nurse is taking care of a client who has been in the intensive care unit (ICU)for 10 days.Which nursing action would cause a decrease in stimulation of the reticular activating system?

Accepted Answer

Keeping the door closed and the lights dim will decrease stimulation of the reticular activating system. The reticular activating system is responsible for regulating sleep and wakefulness, and is sensitive to sensory input, such as light and noise. By reducing these stimuli, the nurse can promote a more restful environment and support the client's recovery. Assisting with activities of daily living and allowing visitors can also be important for the client's well-being, but they may not necessarily decrease stimulation of the reticular activating system. Turning on the television could actually increase stimulation and should be done with caution.

Question 6

A client admitted to the hospital with a possible brain tumor has symptoms of increased thirst and hunger,despite an increase in weight,and complains of feeling cold all the time.Which region of the CNS system most likely has been affected?

Accepted Answer

The hypothalamus is responsible for regulating thirst, hunger, and body temperature. Therefore, the symptoms of increased thirst and hunger, weight gain, and feeling cold all the time suggest the hypothalamus has been affected. A brain tumor in this region could disrupt the regulation of these functions.

Question 7

A client is treated in the emergency department for an overdose of cocaine.The nurse monitors the client based on the knowledge that cocaine affects which item?

Accepted Answer

Cocaine affects the dopamine receptors in the brain, which leads to an increase in dopamine levels that result in the intense feelings of pleasure and euphoria associated with cocaine use. Overdose can lead to a variety of health problems, including seizures, cardiovascular complications, and psychosis.

Question 8

A client is found to have a reduction in the amount of the neurotransmitter acetylcholine.The nurse realizes this client is prone to developing which health problems?
Select all that apply.

Accepted Answer

Myasthenia gravis is associated with a reduction in acetylcholine receptors, and Alzheimer disease is linked to a decrease in acetylcholine levels in the brain, both of which involve the neurotransmitter acetylcholine.

Question 9

A client is prescribed a serotonin supplement.For which disorder(s)is this neurotransmitter replacement indicated?
Select all that apply.

Accepted Answer

The answer of A client is prescribed a serotonin supplement.For...

Question 10

The client is receiving a medication that alters the utilization of glutamate,therefore risking an increase in glutamate levels in the CNS.The nurse should evaluate for which manifestation of high glutamate levels?

Accepted Answer

An increase in glutamate levels in the CNS can lead to neurotoxicity, which is characterized by symptoms such as agitation, confusion, seizures, and other signs of central nervous system dysfunction. Blurred vision and dry mouth are not typical symptoms of high glutamate levels, while ataxia and tremors may be caused by various factors unrelated to glutamate levels.

Question 11

A client with Parkinson disease is prescribed a medication that affects a particular central nervous system neurotransmitter.Which neurotransmitter is the medication acting on to treat the symptoms of Parkinson disease?

Accepted Answer

Parkinson disease is characterized by a deficiency in dopamine neurotransmitter in the brain. The medication prescribed for Parkinson disease acts on the acetylcholine neurotransmitter, which is responsible for reducing dopamine activity in the basal ganglia. By reducing the activity of acetylcholine, dopamine activity increases, which helps to alleviate the symptoms of Parkinson disease.

Question 12

A client recovering from a recent stroke is having difficulty with speech,memory,and movement of the extremities on the left side of the body.The nurse explains to the family that which area of the CNS has most likely been affected by the stroke?

Accepted Answer

The cerebrum is responsible for controlling movement, speech, and memory. Damage to this area of the brain is common with strokes and can lead to the symptoms described in the scenario. The limbic system is not directly involved in these functions and the cerebellum and thalamus are less likely to be affected by a stroke causing these particular symptoms.

Question 13

A client with depression and a sleep disorder is prescribed a central nervous system medication.The nurse will expect to assess which effects of this medication in the client?
Select all that apply.

Accepted Answer

Central nervous system medications used to treat depression and sleep disorders typically have the desired effects of improving mood and sleep patterns. Activation of the fight-or-flight response, onset of seizures, and increased pain levels are not expected effects of these medications.

Question 14

A client is admitted with a spinal cord injury.Which clinical manifestations does the nurse anticipate upon assessment?
Select all that apply.

Accepted Answer

Spinal cord injuries can lead to paresthesia (abnormal sensations such as tingling or prickling) and paralysis (loss of muscle function) due to the disruption of nerve signals.

Question 15

Which statements describe the function of the central nervous system synapse?
Select all that apply.

Accepted Answer

The synapse in the central nervous system can perform various functions, including suppressing (inhibition) or activating (simulation) the firing of neurons, inhibiting the release of neurotransmitters, and releasing inhibitory neurotransmitters that suppress conduction. It does not serve as the primary functioning cell within the nervous system, as neurons are the primary functioning cells.

Question 16

A client,prescribed an antidepressant for symptoms of depression,is expressing feelings of hopelessness and thoughts of suicide.The nurse's response will be based on which conclusion?

Accepted Answer

Antidepressants can have a wide range of effects on individuals due to the variability in how each person's central nervous system (CNS) responds to these medications. This can include differences in therapeutic effects and side effects.

Question 17

The nurse is concerned that a client taking an antipsychotic medication is experiencing extrapyramidal side effects.For which effects should the nurse notify the health care provider?

Accepted Answer

Muscular spasms of the head and neck are indicative of extrapyramidal side effects and should be reported to the healthcare provider immediately. Complaints of slight drowsiness and dry mouth are common side effects of antipsychotic medications and do not necessarily warrant immediate notification. Urinary hesitancy may be a side effect of some antipsychotic medications but is not necessarily indicative of extrapyramidal side effects.

Question 18

The nurse is instructing a client on the effects of a medication on the neurons and synapses within the nervous system.What should the nurse teach about the characteristics of a synapse?
Select all that apply.

Accepted Answer

The answer of The nurse is instructing a client on...
