Q

A 76-year-old patient arrives at the office with his wife with complaints of episodes of slurred speech, word-finding difficulties, and numbness in his arm. The first priority in management is:

  1. Tell him to take an aspirin right away.
  2. Order a CT scan.
  3. Send him to the ER.
  4. Perform an EKG.
A

3. Send him to the ER.

An aspirin is incorrect if you are concerned of stroke and you are not sure if it is hemorrhagic or ischemic in origin. A CT is reasonable, but should be done emergently upon admission to the ER. An EKG would be applicable for chest pain or hospital admission.

Q

A 73-year-old female patient presents with limb paralysis nystagmus, vertigo, nausea, slurred speech, and cerebellar ataxia. An occlusion of which part of the brain is suspected?

  1. Occipital and temporal lobes, dorsal surface of thalamus, upper part of cerebellum, midbrain
  2. Anterior cerebral surfaces
  3. Posterior cerebral surfaces
  4. Parts of the medulla
A

1. Occipital and temporal lobes, dorsal surface of thalamus, upper part of cerebellum, midbrain

The most common areas of occlusion are the ICA or MCA. The midbrain, upper part of the cerebellum and dorsal surface of the thalamus receive blood from the basilar artery, which also supplies the temporal and occipital lobes. Thus, the patient exhibits symptoms in the regions of the brain that have been affected with slurred speech, cerebellar ataxia, nausea and vertigo, and limb paralysis, nystagmus. The posterior cerebral surface would result in bilateral motor sensory, visual complaints, and contralateral hemiplegia. Answer D would result in pain, temperature, and sensation impairment, as well as vertigo and dysphagia—in a contralateral fashion.

Q

An 82-year-old patient presents with a history of TIA and confusion. A sensitive neurologic test for stroke would be what?

  1. The pronator drift
  2. Epley maneuver
  3. Visual field exam
  4. Get-up-and-go test
A

1. The pronator drift

The pronator drift will show upper motor neuron weakness if the patients arm drifts, as well as confusion if they are unable to follow instructions. The Epley maneuver is done for vertigo. Visual fields should be assessed as part of a neuro exam, and the get-up-and-go test is a timed mobility test for the elderly.

Q

A child presents with febrile seizures. Which statement offers the BEST information for the education of the family by the NP?

  1. These types usually present as absence or simple partial seizures.
  2. The child will usually need anticonvulsant therapy for 6 months.
  3. There is a higher risk of developing epilepsy later in life (greater than the general population).
  4. Most occur on the first day of fever; > 75% > 102 degrees.
A

4. Most occur on the first day of fever; > 75% > 102 degrees.

Febrile seizures occur with fever > 100, 75% > 102, and in the absence of an identifiable cause. They do not require treatment and usually occur on the first day the fever does. They are typically generalized, less than 15 minutes in duration, and may have tonic clinic activity. The risk for developing epilepsy later in life is slightly increased from that of the general population (1%).

Q

A 62-year-old woman complains of severe lancinating pain in her right cheek that worsens with cold drinks or teeth brushing. She is afraid to chew or eat because it seems to initiate the attack. The most likely diagnosis is which of the following?

  1. Sinus infection
  2. Abscessed tooth
  3. Trigeminal neuralgia
  4. Bell’s palsy
A

3. Trigeminal neuralgia

Classic symptoms of trigeminal neuralgia is shock-like severe lancinating unilateral pain in the sensory distribution of the trigeminal nerve (CN V), often initiated by cold, chewing, or a sensory stimulus. The etiology is often unknown. Bell’s palsy does not present this way or with the same distribution.

Q

A 35-year-old male c/o (complaints of) the abrupt onset of recurrent “ice pick” headaches behind one eye. He presents to the NP’s office with an acute episode. On physical exam, the patient is noted to have tearing in one eye, ptosis, and nasal discharge/congestion. The NP’s plan for therapeutic management would be which of the following?

  1. High-dose NSAIDs
  2. High-dose oxygen 7–10 L
  3. Send to the ER for CT scan
  4. Verapamil
A

2. High-dose oxygen 7–10 L

This patient meets the classic presentation for cluster headache. He does not need to go to the ER, especially with a “recurrent” history. The presentation of a Horner’s-like syndrome is normal. He will respond to high-dose oxygen for acute treatment. Verapamil should also be titrated or adjusted for prevention.

  1. Normal CRP
  2. ESR 100 mm or >
  3. WBC >15,000
  4. Positive western blot
A

2. ESR 100 mm or >

The ESR would be elevated with a diagnosis of temporal arteritis, which is what this patient most likely has. The CRP should be elevated. The other findings are not consistent with the condition.

Q

When the FNP administers the Mini-mental status exam (MMSE) and asks what is the difference between a river and a lake? He/she is actually measuring which of the following?

  1. Education level
  2. Memory
  3. Abstract thinking
  4. Plasticity
A

3. Abstract thinking

Asking about similarities and differences is abstract thinking. Memory testing would be day, date, month, season etc. The test does not take into account the educational level or measure plasticity.

22
Q

A 22-year-old patient with no cardiovascular history presents with a history of a unilateral headache accompanied by nausea, vomiting, photophobia, or phonobia. What further diagnostics are required to establish the diagnosis?

  1. CT
  2. MRI
  3. No further laboratory investigation is needed
  4. CBC with differential
A

3. No further laboratory investigation is needed

The diagnosis is established on the basis of clinical findings. If there are clinical features that may suggest an alternative diagnosis, then additional laboratory investigations are necessary. If appropriate therapy is initiated and there is a lack of response, than an alternate diagnosis would also be considered.

23
Q

Which of the following medications is the best choice for acute treatment of the patient who presents with unilateral headache accompanied by nausea, vomiting, photophobia or phonophobia?

  1. Triptans
  2. Beta-blockers
  3. NSAIDs
  4. Narcotics
A

1. Triptans

Beta-blockers are preventative therapy. NSAIDs may be used for tension headache or episodic headache. Narcotics are not first-line. Triptans are first-line therapy for a patient without cardiovascular history.

24
Q

Which CN is responsible for shoulder shrugging?

  1. CN X
  2. CN XI
  3. CN IX
  4. CN XII
A

2. CN XI

The vagus nerve is 10, the hypopharyngeal nerve is 9, and hypoglossal is 12; the nerve responsible for the shoulder shrug is CN 11.

25
Q

Which CNs are being tested with EOM?

  1. A CN III, IV, VI
  2. CN III, IV, V
  3. CN II, III, IV
  4. CN II, IV, V

1. A CN III, IV, VI

CN 3—oculomotor medial deviation and all other directions, 4-trochlear (innervates superior oblique and downward gaze), 6 abducens (innervates lateral recturs and lateral gaze). Extraocular range of motion. CN V is the trigeminal nerve.

26
Q

The next patient to be seen by the FNP is a 16-year-old old high school soccer player who suffered a Gr 1 concussion. The best advice at this time would be which of the following?

  1. Pupillary checks every hour, monitor vital signs
  2. You may return to play as soon as your symptoms have resolved
  3. Physical rest × 2 weeks, no contact sports with medical follow-up
  4. Physical and cognitive rest monitored by medical personnel. Monitor for emotional symptoms, headaches difficulty remembering, feeling foggy, trouble concentrating
A

2. You may return to play as soon as your symptoms have resolved

It needs to be monitored by medical personnel; some athletes will be inappropriately anxious to return to sport.

27
Q

The classic presentation of carpal tunnel syndrome includes repetitive use and gradual onset of tingling (paresthesias) in which fingers?

  1. Thumb, index, and middle finger
  2. Index, middle, and fifth finger
  3. All the fingers of the hand
  4. Thumb
A

1. Thumb, index, and middle finger

Median nerve compression results in thumb, index finger, and middle finger symptoms.

28
Q

During the neurologic exam, a patient has had a positive Romberg test. This highlights an issue in what part of the neurologic system?

  1. The sensory system and balance
  2. Mental status
  3. The motor system
  4. The reflex system
A

1. The sensory system and balance

The Romberg test helps assess proprioception—sensory and balance.

29
Q

Which statement below best describes a positive Romberg test?

  1. The patient is unable to walk in a straight line with one foot in front of the other.
  2. The patient holds arms straight forward with eyes closed.
  3. The patient stands with feet together, eyes closed, arms at side with excessive swaying—begins to fall down and keeps feet far apart to maintain balance.
  4. Patient places outstretched arms with palms facing up and closed eyes. One arm goes downward after 5–10 seconds.
A

3. The patient stands with feet together, eyes closed, arms at side with excessive swaying—begins to fall down and keeps feet far apart to maintain balance.

Tandem gait test. The exam where the patient holds arms straight forward with their eyes closed is a negative test. The exam where the patient places their outstretched arms with palms facing up and closed eyes is a motor exam for pronator drift.

30
Q

Serious causes of headache that require immediate urgent referral include which of the following?

  1. Migraine
  2. Hypertension
  3. Cervical spondylosis
  4. TIA
A

4. TIA

A careful history and physical would delineate the cause. Migraine can be diagnosed clinically and does not need further workup. Hypertension can be serious if not controlled, but is not usually the reason for immediate urgent referral. Patients with hypertensive crisis would require an urgent referral.

31
Q

An 18-year-old male college student is being evaluated by the FNP at the student health center. He has had a fever > 102 F for approximately 24 hours and c/o severe headache. During the examination, the patient is directed to lay in a supine position and passively bend his neck toward his chest; he flexes his knees and hips. What is the name of this maneuver?

  1. Brudzinski
  2. Kernig
  3. Cullens
  4. Lachman
A

1. Brudzinski

The Lachman test is a test for integrity of the ACL. Kernig’s sign is also a test for meningeal irritation: In the supine position, with the hip flexed at 90 degrees, resistance or discomfort is felt in the back and posterior thigh with passive knee extension. Cullen’s sign is superficial edema and bruising in the subcutaneous fatty tissue around the umbilicus, following rupture of ectopic or intraperitoneal hemorrhage.

32
Q

Which of the following factors is NOT contributory toward the development of Bell’s palsy?

  1. Pregnancy
  2. Diabetes
  3. Lyme disease
  4. Heart disease
A

4. Heart disease

All but heart disease are contributory. Between 7–9% of patients have recurrence.

33
Q

Bell’s palsy presents as acute weakness or paralysis of the muscles supplied by which cranial nerve(s)?

  1. VI
  2. V
  3. VII
  4. VII and VIII
A

3. VII

The facial nerve is CN VII. It is the only one affected.

34
Q

A 32-year-old patient with migraines and a history of asthma is complaining of two migraine headaches per week despite treatment with triptans. The next consideration for treatment is which of the following?

  1. Discontinue triptans and offer NSAIDs.
  2. Start topiramate as preventative therapy.
  3. Start propranolol or timolol as preventative therapy.
  4. Order an MRI.
A

2. Start topiramate as preventative therapy.

The patient is a candidate for prophylaxis because she is having two or more migraines per week, and may be heading toward medication overuse. She should not use a beta-blocker with asthma; topiramate or another option should be considered. An MRI is not necessary because there is no acute change, neurologic deficits, or red flags.

35
Q

A new patient explains that she has a history of migraines with aura. Counseling should include which of the following?

  1. Headaches that occur as a result of aura may last much longer and be more serious than those without.
  2. There is controversy over the use of oral contraceptives and she may want to consider another form of contraception.
  3. A visual scotoma (circumscribed vision loss) is caused by cerebral ischemia in the middle or posterior cerebral artery.
  4. The aura can be a jabbing “ice pick” feeling in the head or over one eye that lasts seconds.
A

2. There is controversy over the use of oral contraceptives and she may want to consider another form of contraception.

Migraine with aura may be an independent risk factor for stroke in women < 45. Headaches following an aura do not have to last longer or be worse than those without, and the aura is not due to ischemia. The last answer describes cluster symptoms.

36
Q

An 80-year-old patient was admitted to the hospital with confusion this week. Her daughter tells the hospitalist her memory may be slipping a bit, but she was oriented and independent last week, driving herself to the market. Upon admission to the hospital, she is found to have pneumonia. Currently, she is difficult to arouse and has incoherent speech. Last night, she was up all night and seemed to know her daughter but was confused regarding place and time. Her CT was normal. The most appropriate diagnosis of consideration at this time is which of the following?

  1. Dementia
  2. Parkinson’s disease
  3. Stroke
  4. Delirium
A

4. Delirium

This meets the criteria of the acute mental disturbance characterized by confusion, impaired thinking, and cognition and attention deficit with a fluctuating course.

37
Q

A 70-year-old patient has c/o of gradual memory loss without neurologic deficits. The best method of evaluation at this time would be which of the following?

  1. Administering a MMSE
  2. CT of the brain
  3. Neuropsychological testing
  4. Meeting with the family to obtain a history
A

1. Administering a MMSE

The Mini-Mental Status Exam is a screening tool that would give you a baseline. Neuropsychological testing would be beneficial depending on the findings. Meeting with the family is always important to obtain a thorough history and for verification. The FNP would not want to do that first; only after issues were identified.

38
Q

A family member of an 85-year-old Alzheimer’s patient wants to know what the risk factors are for getting the disease? Which of the following statements would be the best response?

  1. “If we can scan your brain and offer you treatment, we can prevent the disease from progressing.”
  2. “They have not found an association with vascular disease, diabetes, or hypertension.”
  3. “There is some genetic risk, but advancing age is the biggest risk factor.”
  4. “More men than women get the disease; there is a protective effect with estrogen.”
A

3. “There is some genetic risk, but advancing age is the biggest risk factor.”

There is no preventive treatment at this time. The medications are only for once the disease is diagnosed. There is an association with vascular disease, diabetes, and hypertension. Advancing age is the biggest risk factor, with prevalence doubling every 5 years after 65. More women than men have AD.

39
Q

Which of the following medications should be considered as first-line therapy for patients with mild to moderate Alzheimer’s disease?

  1. Anticholinergics
  2. Ace inhibitors
  3. Cholinesterase inhibitors
  4. Antidepressants
A

3. Cholinesterase inhibitors

The only drugs approved for use for mild–moderate AD are the anticholinesterase inhibitors.

40
Q

A patient presents with decreased arm swing and cogwheel rigidity. What conditions are these a manifestation of?

  1. Multiple sclerosis
  2. Vascular dementia
  3. Parkinson’s disease
  4. Rheumatoid arthritis
A

3. Parkinson’s disease

Patients with Parkinson’s disease may demonstrate decreased arm swing, and cogwheel rigidity in upper limbs as a result of increased tone. Upon exam, there is resistance and a ratchetlike rhythmic contraction of the muscle as the practitioner moves the limb through the range of motion (elbow, wrist).

41
Q

A 28-year-old female presents with weakness, complaints of fatigue, recent problems with diplopia, numbness of her left arm, and some bladder changes. She remembers something similar happening last year. What would be in the differential?

  1. Migraine with aura
  2. Multiple sclerosis
  3. Meningitis
  4. Pituitary tumor
A

2. Multiple sclerosis

Multiple sclerosis presents with varying deficits at different times due to the multifocal demyelination and inflammation. Common symptoms include gait ataxia, visual loss, diplopia, paresthesias, weakness, and fatigue.

42
Q

A 22-year-old college student presents with an acute onset of high fever, chills, nausea, slight confusion, and is noted to have a headache and petechiae. The exam reveals a + Kernig’s sign. The most appropriate next step in management would be which of the following?

  1. Tell him this looks viral, offer NSAIDs around the clock, check a throat culture to verify, and have the patient come back in 24–48 hours if he’s not feeling better.
  2. Perform throat culture; treat empirically since he lives in a college dorm.
  3. Check for mono—Send off EBV/Mono spot, throat culture, treat empirically.
  4. Send him to the ER for an LP and further evaluation.
A

4. Send him to the ER for an LP and further evaluation.

This patient matches all the features of meningitis; sudden onset fever chills, systemic illness, neck stiffness in a previously healthy young adult in group living puts him at high risk. Concerning features are the change in mental status and meningeal irritation.

43
Q

What recommendation should the NP offer to a high school soccer player who has suffered a mild concussion?

  1. “You may return to play in 1 week.”
  2. “You may not return to play until resolution of all of your symptoms during both exercise and rest.”
  3. “You may return to play after resolution of your symptoms and a follow-up CT scan.”
  4. “Since you did not suffer loss of consciousness (LOC), you may return to play.”
A

2. “You may not return to play until resolution of all of your symptoms during both exercise and rest.”

Loss of consciousness is not a reliable indicator for dysfunction or recovery. CT imaging is only used LOC with more serious TBI, rule out subarachnoid hemorrhage, post-traumatic amnesia, focal neurologic deficits, skull fracture, or an alteration in mental status that persists. For athletes, there is no set time period: There should be no return to play until there is complete resolution of all symptoms at exercise and rest.

44
Q

Patients who have experienced concussive events are at risk for developing which of the following?

  1. Headache
  2. Dizziness
  3. Processing disturbance
  4. All of these
A

4. All of these

Post-concussive syndrome can develop (headache, dizziness, concentration/processing disturbance) after concussion, as well as other long-term permanent impairment for repetitive concussions.

45
Q

Which type of dementia has a step-wise progression in memory loss, may present with an abnormal neuro exam or gait, and is often seen with multiple infarcted areas of the brain?

  1. Metabolic encephalopathy
  2. Alzheimer’s dementia
  3. Lewy body dementia
  4. Vascular dementia
A

4. Vascular dementia

Vascular Dementia is a STEPWISE progression of decrease in cognition with memory loss occurring later than AD. It often presents with an abnormal neuro exam, exaggerated DTR, weakness. AD is a gradual decline with a normal exam. There can be mixed dementia. A is treatable, and C is in same category with AD: degenerative type with fluctuating cognition.

46
Q

A patient presents with complaints of moderate headache pain that is bilateral, does not increase with activity level, but is aggravated by stress. It seems to come and go at times, but can last from one hour to sometimes all day. This is likely which of the following?

  1. Migraine headache
  2. Potential brain tumor
  3. Tension headache
  4. Cluster headache
A

3. Tension headache

Episodic tension headache is the most common, bilateral type headache and can last anywhere from 30 min to 2 days. The pain can be mild to moderate.

47
Q

A 60-year-old man with TIA and atrial fibrillation is currently being treated with Apixaban, one of the new oral anticoagulants. What is an important teaching point for this patient today?

  1. He must watch the vitamin K in his diet because it can interfere with the medication.
