The nurse is assessing cognitive function in a client who experienced a cerebral vascular accident (CVA). Which should the nurse focus on during the assessment process?
-
Ability to see clearly and read written instructions
-
Orientation to time, place, and person
-
Ability to smell items while eyes are closed
-
Ability to walk with a smooth, steady gait
Explanation
Orientation to time, place, and person is a fundamental component of cognitive function assessment, directly evaluating a client's awareness and mental status, which is particularly important following a CVA due to the risk of cognitive impairment from brain injury.
Why the other options are incorrect:
A. Ability to see clearly and read written instructions — This assesses visual acuity (a function of cranial nerve II and the visual pathways), not cognitive function specifically.
C. Ability to smell items while eyes are closed — This assesses cranial nerve I (olfactory nerve) function, a sensory assessment, not cognitive function.
D. Ability to walk with a smooth, steady gait — This assesses motor coordination and cerebellar function, not cognitive function.
-
11
-
10
-
8
-
7
Explanation
Correct Answer: (B) 10
The client's score is calculated as follows: Eye Opening Response — eyes open to verbal command, speech, or shout = 3 points; Verbal Response — inappropriate responses, words discernible = 3 points; Motor Response — withdraws from pain = 4 points. Adding these together: 3 + 3 + 4 = 10 points.
Why the other options are incorrect:
A. 11 This total does not match the sum of the individual scores (3 + 3 + 4 = 10) based on the client's documented responses.
C. 8 This total is too low and would correspond to different, more impaired responses than those described for this client.
D. 7 This total is too low and would correspond to more severely impaired responses than those documented, placing the client incorrectly in the severe brain injury category.
-
The lowest, left-most red dot (located at the 5th intercostal space, left midclavicular line)
-
The upper dot on the right sternal border (2nd intercostal space)
-
The upper dot on the left sternal border (2nd intercostal space)
-
The middle dot on the left sternal border (3rd intercostal space, Erb's point)
-
The dot at the 4th intercostal space, left sternal border
Explanation
Correct Answer: The lowest, left-most red dot (located at the 5th intercostal space, left midclavicular line)
The apical pulse, which corresponds to the point of maximal impulse (PMI), is best auscultated at the 5th intercostal space along the left midclavicular line. This location corresponds to the anatomical position of the heart's apex (mitral valve area) and is the lowest dot positioned furthest to the left/down on the diagram.
Why the other options are incorrect:
The upper dot on the right sternal border (2nd intercostal space) corresponds to the aortic valve, not the apical pulse.
The upper dot on the left sternal border (2nd intercostal space) corresponds to the pulmonic valve, not the apical pulse.
The middle dot on the left sternal border (3rd intercostal space, Erb's point) is used for detecting murmurs from both aortic and pulmonic origins, not the apical pulse.
The dot at the 4th intercostal space, left sternal border, corresponds to the tricuspid valve, not the apical pulse.
The nurse is preparing to measure jugular vein distention. Which position should the nurse place the client in?
-
Supine
-
Side lying
-
Prone
-
Semi-Fowler's
Explanation
The semi-Fowler's position, typically at a 30- to 45-degree elevation, is used to measure jugular vein distention because it allows for optimal visualization of the internal jugular vein while still permitting an accurate assessment of venous pressure.
Why the other options are incorrect:
A. Supine Lying completely flat causes the jugular veins to distend even in healthy clients, making it difficult to obtain an accurate assessment.
B. Side lying This position does not provide an accurate view of the jugular vein for proper assessment of distention.
C. Prone This position is not used for cardiovascular assessments and would make visualization of the jugular veins impossible.
A client reports double vision and difficulty tracking objects. During the assessment, the nurse notes that the client's eyes do not move smoothly in all directions. Which cranial nerves may be affected? (Select all that apply)
-
Oculomotor nerve (Cranial Nerve III)
-
Trochlear nerve (Cranial Nerve IV)
-
Facial nerve (Cranial Nerve VII)
-
Abducens nerve (Cranial Nerve VI)
-
Optic nerve (Cranial Nerve II)
Explanation
The oculomotor (CN III), trochlear (CN IV), and abducens (CN VI) nerves work together to control the extraocular muscles responsible for eye movement in all directions. Dysfunction of any of these three nerves can result in impaired smooth eye tracking and double vision (diplopia).
Why the other options are incorrect:
C. Facial nerve (Cranial Nerve VII) — This nerve controls the muscles of facial expression, not extraocular eye movement, so it would not be responsible for the tracking difficulty described.
E. Optic nerve (Cranial Nerve II) — This nerve is responsible for vision (transmitting visual information from the retina), not eye movement, so it would not cause difficulty tracking objects smoothly.
The nurse is completing a neurological examination on a client with Parkinson's disease. During the assessment of sensory function, the nurse should perform which of the following?
-
Ask the client to walk in a heel-to-toe fashion across the room.
-
Ask the client to hold the nurse's fingers and gradually increase the grip on the nurse's fingers.
-
Ask the client to verify his full name and date of birth.
-
Ask the client to identify the difference between sharp and dull objects on the skin.
Explanation
Correct Answer: (D) Ask the client to identify the difference between sharp and dull objects on the skin
This instruction assesses sensory function by testing the client's ability to discriminate between different sensory stimuli (sharp versus dull) on the skin, directly evaluating the peripheral sensory nervous system pathways.
Why the other options are incorrect:
A. Ask the client to walk in a heel-to-toe fashion across the room. — This instruction (tandem gait) assesses motor coordination and cerebellar function/balance, not sensory function.
B. Ask the client to hold the nurse's fingers and gradually increase the grip on the nurse's fingers. — This instruction assesses motor strength, not sensory function.
C. Ask the client to verify his full name and date of birth. — This instruction assesses orientation and cognitive function, not sensory function.
The nurse is assessing cranial nerve VII (facial nerve). Which assessment finding indicates the client's facial nerve is intact?
-
The face is symmetrical when the client smiles
-
The client moves the eyes in all directions
-
The client shrugs the shoulders against resistance
-
The client protrudes the tongue and moves it side to side
Explanation
The facial nerve (Cranial Nerve VII) innervates the muscles of facial expression. Symmetrical facial movement during smiling indicates intact bilateral facial nerve function, as asymmetry would suggest a facial nerve deficit (such as Bell's palsy or stroke).
Why the other options are incorrect:
B. The client moves the eyes in all directions — This assesses cranial nerves III, IV, and VI (oculomotor, trochlear, and abducens), which control eye movement, not the facial nerve.
C. The client shrugs the shoulders against resistance — This assesses cranial nerve XI (spinal accessory nerve), which controls the trapezius muscle, not the facial nerve.
D. The client protrudes the tongue and moves it side to side — This assesses cranial nerve XII (hypoglossal nerve), which controls tongue movement, not the facial nerve.
How should the nurse assess a client's pupillary response during a neurological assessment?
-
Have the client close their eyes tightly and reopen them while observing pupil size.
-
Place a hand on the client's forehead and ask them to resist opening their eyes.
-
Ask the client to follow an object with their eyes in six different directions.
-
Dim the lights, ask the client to focus on a distant object, and shine a light into each eye.
Explanation
Assessing pupillary response requires a darkened environment to observe the pupils' reaction to light accurately. Having the client focus on a distant object prevents accommodation from affecting the results, and shining a light into each eye allows the nurse to assess both direct and consensual pupillary constriction.
Why the other options are incorrect:
A. Have the client close their eyes tightly and reopen them while observing pupil size. This assesses eyelid strength and function, not pupillary response to light.
B. Place a hand on the client's forehead and ask them to resist opening their eyes. This tests cranial nerve function related to eyelid strength, not pupillary response.
C. Ask the client to follow an object with their eyes in six different directions. This assesses extraocular movements and cranial nerve function for eye muscles, not pupillary response.
A 45-year-old client presents to the emergency department after a motor vehicle accident. During the neurological exam, the nurse notes that the client is exhibiting marked personality changes, poor judgment, and difficulty with impulse control. Which lobe of the brain is most likely affected by the injury?
-
Occipital
-
Parietal
-
Frontal
-
Temporal
Explanation
The frontal lobe is responsible for higher-order executive functions, including personality regulation, judgment, decision-making, and impulse control. Damage to this lobe commonly results in marked personality changes, poor judgment, and disinhibited or impulsive behavior, as demonstrated by this client following traumatic injury.
Why the other options are incorrect:
A. Occipital — The occipital lobe is primarily responsible for visual processing, not personality, judgment, or impulse control.
B. Parietal — The parietal lobe is primarily responsible for processing sensory information and spatial awareness, not personality regulation or impulse control.
D. Temporal — The temporal lobe is primarily involved in auditory processing, memory, and language comprehension, not the personality and impulse control changes described in this scenario.
-
Decerebrate posturing
-
Decorticate posturing
-
Clonus
-
Asterixis
Explanation
Looking at the image, the client's arms are shown extended and rotated at the sides of the body, with legs extended, which is characteristic of decerebrate posturing. This abnormal posturing indicates a severe brainstem injury, as the extended limb position results from loss of inhibitory input to extensor muscle pathways.
Why the other options are incorrect:
B. Decorticate posturing — This posturing is characterized by flexion of the arms toward the core/chest with extension of the legs, which differs from the extended arm position shown in this image; decorticate posturing indicates a lesion above the brainstem (in the cerebral hemispheres or internal capsule).
C. Clonus — Clonus refers to rhythmic, involuntary muscle contractions typically seen at the ankle or wrist in response to reflex testing, not a static body positioning response to noxious stimuli.
D. Asterixis — Asterixis refers to a brief, involuntary "flapping" tremor of the hands (often seen in hepatic encephalopathy) elicited when the wrists are extended, not a full-body posturing response to painful stimuli.
