Example Questions

Example Question #31 : Neural And Psychological Conditions

Which of the following herbs has been shown to be effective in prevention of migraine symptoms?

Possible Answers:

Uncaria tomentosa (cat's claw)

Agrimonia eupatoria (agrimony)

Petasites hybridus (butterbur)

Hypericum perforatum (St John's wort)

Correct answer:

Petasites hybridus (butterbur)

Explanation:

Petasites hybridus (butterbur) is a flowering plant of the family asteraceae. It has been shown in studies to reduce the frequency of migraine headaches by as much as 68%. None of the other herbs listed have any significant medicinal benefit in migraine headaches. 

Example Question #34 : Neural And Psychological Conditions

Which of the following interventions has been shown to be effective in reducing the severity of pain in cluster headaches?

Possible Answers:

Hot and cold alternating applications

100% oxygen at minimum 12 liters per minute

Heel-drop maneuver

Carotid sinus massage

Correct answer:

100% oxygen at minimum 12 liters per minute

Explanation:

One non-pharmaceutical intervention that has shown to provide relief for a significant number of individuals with cluster headaches is 100% oxygen, delivered via mask at a minimum of 12 liters per minute. Relief can be felt in as little as 15 minutes. None of the other interventions mentioned would be likely to improve symptoms of a cluster headache.

Example Question #4 : Causes And Treatments Of Neural Conditions

Bell's palsy is associated with infection by which of the following pathogens?

Possible Answers:

Herpes simplex 1

Herpes zoster

Epstein Barr virus

All of these are correct

Correct answer:

All of these are correct

Explanation:

While Bell's palsy is most frequently associated with prior infection with herpes simplex 1, is may also be associated with cytomegalovirus, Epstein Barr virus, and herpes zoster.

Example Question #1103 : Nclex

What is the prognosis with Bell's palsy?

Possible Answers:

Corticosteroid treatment is required to prevent permanent loss of taste

Self-resolving in 1-6 months

Nerve resection is required to prevent corneal abrasions

Antiviral treatment is required to prevent permanent paralysis

Correct answer:

Self-resolving in 1-6 months

Explanation:

In the vast majority of cases Bell's palsy resolves within 1-6 months without medical intervention. Moistening of the affected eye (rather than nerve resection) is required during this period to prevent corneal damage. There is very little risk of permanent paralysis or loss of taste. 

Example Question #1104 : Nclex

All of the following are common etiologies of seizure disorders except __________.

Possible Answers:

infection

brain tumor

marijuana use

genetic predisposition

Correct answer:

marijuana use

Explanation:

The most common causes of seizures include brain injury or tumor, genetic predisposition, medications, and infections such as meningitis. While marijuana may be a trigger for sensitive individuals with seizure disorders, it has not been known to cause seizures in a non-epileptic individual and has shown to reduce seizure incidence in some individuals with this condition when used in a medical setting. 

Example Question #1105 : Nclex

All of the following medications are considered first-line treatments of absence seizures except __________.

Possible Answers:

Ethosuximide

Valproic acid

Lamotrigine

Carbamazepine

Correct answer:

Carbamazepine

Explanation:

The most commonly prescribed medication for absence seizures is Ethosuximide. Lamotrigine and valproic acid may also be used if seizures are unable to be controlled with ethosuximide. Carbamazepine, a common medication prescribed for simple and complex partial seizures, is specifically contraindicated in absence seizures. 

Example Question #1106 : Nclex

A patient is hospitalized for alcohol withdrawal and is started on medication to prevent complications from withdrawal. Which type of medication is used to attenuate the possibility of seizures during this hospitalization?

Possible Answers:

Anti-epileptic drug (AED)

Typical antipsychotic

Benzodiazepines

Selective serotonin re-uptake inhibitor (SSRI)

Atypical antipsychotic

Correct answer:

Benzodiazepines

Explanation:

Benzodiazepines are the mainstay of treatment for alcohol withdrawal. Anti-epileptic drug (AEDs) are not to be used during alcohol withdrawal, and are reserved for patients who have a true seizure disorder. The Clinical Institute Withdrawal Assessment for Alcohol (CIWA) protocol is used as symptom based therapy with benzodiazepines to prevent seizures and other complications from withdrawal.

Example Question #41 : Neural And Psychological Conditions

Which of the following is the first-line treatment for cauda equina syndrome?

Possible Answers:

Physiotherapy 

Muscle relaxants

Surgical decompression

Chiropractic manipulation

Correct answer:

Surgical decompression

Explanation:

Cauda equina syndrome is a serious condition in which the cauda equina is disturbed within the spinal cord, generally due to impingement, trauma, local lesion, or compression. The first-line treatment is surgical decompression. Neither physiotherapy nor muscle relaxants would address the cause of this condition, and chiropractic manipulation may actually exacerbate the symptoms. 

Example Question #1 : Symptoms And Tests For Neural Conditions

A client admitted to the neuro intensive care unit is having his level of responsiveness assessed by the nurse on duty. Her findings include eyes opening to verbal command, is disoriented but can converse, and obeys commands.

 What is this client's Glasgow Coma Scale score?

Possible Answers:


Correct answer:

Explanation:

The score of this client includes: eye open response is a , best verbal response is  and best motor response is .

Example Question #2 : Symptoms And Tests For Neural Conditions

An unconscious patient exhibits stiffly extended arms that are also adducted with the wrists hyperpronated. The nurse recognizes this presentation to be __________.

Possible Answers:

vestibulospinal reflex

Babinski reflex

crossed extensor reflex

decerebrate positioning

decorticate positioning

Correct answer:

decerebrate positioning

Explanation:

Decerebrate positioning is an involuntary response of abduction, extension, and hyperpronation of the upper extremities due to noxious stimuli. There also is hyperextension of the lower extremities and the feet are plantarflexed. Decorticate positioning involves "mummy baby" posture - elbows, wrists, and fingers flexed, and legs extended and rotated medially. The Babinski reflex involves the extension of the big toe following stimulation of the sole of the foot. The crossed extensor reflex is also known as the withdrawal reflex, which involves the differential flexion and relaxation of muscles in the withdrawal of a limb. Vestibulospinal reflexes involve the use of vestibular organs and skeletal muscle to maintain balance, posture, and coordination.
