1. What does dullness when percussing lung fields: Jarvis pg 427 • Hyperresonance is a lower-pitched, booming sound found when too much air is present such as in emphysema or pneumothorax. A dull note (soft, muffled thud) signals abnormal density in the lungs, as with pneumonia, pleural effusion, atelectasis, or tumor. • Lungs are hyperinflated with chronic emphysema, which results in hyperresonance where you would expect cardiac dullness. Dullness behind the right breast occurs with right middle lobe pneumonia. • Asymmetry is important: one side with prominent dullness or marked hyperresonance indicates underlying disease. Hyperresonance is a lowerpitched, booming sound found when too much air is present such as in emphysema or pneumothorax. A dull note (soft, muffled thud) signals abnormal density in the lungs, as with pneumonia, pleural effusion, atelectasis, or tumor 2. Facial sensation controlled by which CN: Jarvis 283, • the trigeminal nerve (CN V) carries the afferent sensation into the brain, and the facial nerve (CN VII) carries the efferent message that stimulates the blink. • Note the facial expression and the symmetry of movement, which reflect the functioning of cranial nerve VII. Also, observe for any involuntary movements, edema, or lesions. 3. Know what two salivary glands are accessible during exam  The sublingual and submandibular salivary glands are accessible to examination, but the parotid glands are in the cheeks over the mandible and are not normally palpable. 4. What CN is being assessed when pt shrugs shoulders Jarvis 646  The major neck muscles are the sternomastoid and the trapezius and are innervated by cranial nerve XI. 5. What muscles are being assessed when assessing CN 11 (spinal accessory nerve) • The sternomastoid muscle divides each side of the neck into two triangles. It accomplishes head rotation and flexion. The anterior triangle extends to the mandible above and the midline of the body medially. The posterior triangle lies behind the sternomastoid muscle and in front of the trapezius. • Examine the sternomastoid and trapezius muscles for equal size 6. Concern for malignant nodules versus benign lymph nodule  If palpation reveals lymph node abnormalities, explore the area proximal to the affected node. This requires familiarity with lymphatic drainage. • If the thyroid is enlarged, auscultate it for bruits, a soft pulsatile, whooshing sound. 7. Know what you’d do next if you palpated a submental lymph node: Jarvis pg 253  The submental nodes are midline structures behind the tip of the mandible. • Knowledge of lymphatic drainage is important because the presence of an enlarged lymph node may signal disease in the area draining into it • Oral cancer sites include the floor of the mouth, ventral and lateral borders of the tongue, retromolar trigone and the soft palate/tonsillar complex. 8. Define visual acuity • the relative ability of the visual organ to resolve detail that is usually expressed as the reciprocal of the minimum angular separation in minutes of two lines just resolvable as separate and that forms in the average human eye an angle of one minute • keenness of sight or the resolving power of the eye (visual system) that can be defined in different ways limited by the optics of the eye and anatomy and physiology of the visual system • the resolving power of the eye or ability to identify a gap or the ability to see two objects as separate Quiz 2 study guide NR 509 week 2 with correct answers 2020 9. Know what to do if your patient can’t read the largest number on the Snellen chart: Jarvis 289  If the person is unable to see even the largest letters, shorten the distance to the chart until it is seen and record that distance (e.g., “10/200”). If visual acuity is even lower, assess whether the person can count your fingers when they are spread in front of the eyes or distinguish light perception from your penlight.
