A patient presents to the Emergency Department (ED) reporting right facial weakness. The nurse understands that a patient suffering from Bell's Palsy will exhibit which assessment findings related to the cranial nerve involvement?
painful areas on the affected side following 3 branches of the nerve
decreased visual acuity when tested with Snellen Chart
unilateral upper and lower facial weaknesses including forehead
facial dropping, with arm and leg weakness on the affected side
The Correct Answer is C
A) Painful areas on the affected side following 3 branches of the nerve:
This is not typically a feature of Bell's Palsy. Bell's Palsy is primarily a motor dysfunction of the facial nerve (cranial nerve VII), leading to facial weakness. The pain associated with Bell's Palsy, if present, is usually mild and localized to the jaw, behind the ear, or along the jawline rather than along all three branches of the trigeminal nerve (cranial nerve V), which controls sensation in the face. Therefore, this choice is not consistent with the typical presentation of Bell's Palsy.
B) Decreased visual acuity when tested with Snellen Chart:
Decreased visual acuity is not a primary feature of Bell's Palsy. This condition specifically affects facial nerve function, which controls the muscles of facial expression, including those responsible for closing the eyes tightly. However, Bell's Palsy does not typically result in visual changes such as decreased visual acuity or problems with vision itself. Decreased vision would be more indicative of an issue with the optic nerve (cranial nerve II) or other eye-related conditions.
C) Unilateral upper and lower facial weakness including forehead:
This is the hallmark sign of Bell's Palsy. The facial nerve (cranial nerve VII) controls the muscles of the face, and when it becomes affected by Bell's Palsy, both the upper and lower parts of the face on one side can be weak or paralyzed. Importantly, Bell's Palsy causes inability to wrinkle the forehead, which distinguishes it from stroke, where the forehead is typically spared because the upper part of the facial muscles receives bilateral input from the brain. Thus, both upper and lower facial weakness, including inability to raise the eyebrow (forehead), is characteristic of Bell's Palsy.
D) Facial dropping, with arm and leg weakness on the affected side:
Facial drooping is a common symptom of Bell's Palsy, but arm and leg weakness is not associated with it. Arm and leg weakness on the same side would be more suggestive of a stroke affecting the cerebrovascular system, rather than a peripheral nerve issue like Bell's Palsy. Bell's Palsy is confined to facial nerve dysfunction and does not cause weakness in the limbs.

Correct Answer is B
Explanation
A) Clubbing of the fingers
Clubbing of the fingers is typically associated with chronic hypoxia, often due to conditions like chronic obstructive pulmonary disease (COPD), congenital heart defects, or chronic respiratory disorders. While mitral valve stenosis can lead to pulmonary congestion and sometimes hypoxia, clubbing is not a hallmark finding of mitral valve stenosis.
B) A heart murmur
Mitral valve stenosis is commonly characterized by a heart murmur. The stenosis (narrowing) of the mitral valve obstructs blood flow from the left atrium to the left ventricle, leading to turbulent blood flow. This creates a characteristic diastolic murmur (a low-pitched, rumbling murmur heard best at the apex of the heart with the patient in the left lateral decubitus position).
C) Barrel chest
A barrel chest is more commonly associated with chronic obstructive pulmonary disease (COPD), emphysema, and other conditions that cause long-term hyperinflation of the lungs. It is not a typical finding in mitral valve stenosis. The shape of the chest may change over time in patients with severe left-sided heart failure, but this is not a primary or direct consequence of mitral valve stenosis.
D) Bradycardia
Bradycardia (a slow heart rate) is not a characteristic finding of mitral valve stenosis. In fact, mitral valve stenosis can lead to increased heart rates due to reduced cardiac output and compensatory mechanisms. As the left atrium becomes increasingly distended from the obstruction, atrial fibrillation (a rapid, irregular heartbeat) is common in mitral valve stenosis.
Correct Answer is A
Explanation
A) Glasgow Coma Scale:
The Glasgow Coma Scale (GCS) is a standardized neurological assessment tool used to assess a patient's level of consciousness based on three criteria: eye opening, verbal response, and motor response. Each of these categories is scored, and the total score helps to determine the depth of the patient's consciousness. The GCS is commonly used to monitor changes in a patient's neurological status, especially after trauma, stroke, or other conditions that may impair brain function.
B) NIH Stroke Scale:
The NIH Stroke Scale (NIHSS) is used to assess the severity of stroke symptoms and includes measures such as facial droop, arm and leg motor function, speech, and language abilities. It is used specifically to evaluate stroke symptoms and is not designed for the rapid assessment of general consciousness like the Glasgow Coma Scale.
C) Romberg Test:
The Romberg Test is a test of balance that is performed by having the patient stand with their feet together, eyes closed, and observing for any swaying or loss of balance. It is used to evaluate proprioception and cerebellar function, not to assess the level of consciousness.
D) Mini Mental Status Exam:
The Mini-Mental Status Exam (MMSE) is a brief cognitive screening tool that assesses aspects of cognitive function such as orientation, attention, memory, language, and visuospatial skills. While the MMSE can provide insight into cognitive function, it does not focus on the specific assessment of consciousness level (eye opening, verbal response, motor response) as the GCS does.
