NSG 3160 EXAM 3 COMPLETE QUESTIONS WITH 100% VERIFIED ANSWERS 1. Which of these statements is true regarding the vertebra prominens? The vertebra prominens is: A. uThe spinous process of C7/u B. The transverse process of C6 C. The spinous process of T1 Rationale: The vertebra prominens is the prominent spinous process of C7, palpable at the base of the neck. ________________________________________ 2. When performing a respiratory assessment on a patient, the nurse notices a costal angle of approximately 90 degrees. This characteristic is: A. A sign of chronic obstructive pulmonary disease B. uA normal finding in a healthy adult/u C. Indicative of pectus excavatum Rationale: A costal angle of about 90 degrees is normal; a wider angle suggests hyperinflation. ________________________________________ 3. When assessing a patients lungs, the nurse recalls that the left lung: A. Consists of three lobes B. uConsists of two lobes/u C. Has no fissures Rationale: The left lung has two lobes (upper and lower); the right lung has three. ________________________________________ 4. Which statement about the apices of the lungs is true? The apices of the lungs: A. Extend 5 to 6 cm above the clavicles B. Extend 3 to 4 cm above the inner third of the clavicles C. uExtend 3 to 4 cm above the inner third of the clavicles/u (Note: B and C are identical in your paste — keeping as written) Rationale: The lung apices rise 3–4 cm above the inner third of the clavicles. ________________________________________ 5. During an examination of the anterior thorax, the nurse is aware that the trachea bifurcates anteriorly at the: A. Sternal angle B. Suprasternal notch C. uSternal angle/u (A and C are identical in your paste — keeping as written) Rationale: The tracheal bifurcation occurs at the sternal angle (angle of Louis). ________________________________________ 6. During an assessment, the nurse knows that expected assessment findings in the normal adult lung include the presence of: A. uMuffled voice sounds and symmetric tactile fremitus/u B. Bronchophony and egophony C. Absent tactile fremitus and clear voice sounds Rationale: Normal lungs have muffled voice sounds and symmetric, palpable tactile fremitus. ________________________________________ 7. The primary muscles of respiration include the: A. Sternocleidomastoid and scalenes B. uDiaphragm and intercostals/u C. Abdominals and pectorals Rationale: The diaphragm and external intercostals are the primary muscles of respiration. ________________________________________ 8. A 65-year-old patient with a history of heart failure comes to the clinic with complaints of being awakened from sleep with shortness of breath. Which action by the nurse is most appropriate? A. Tell the patient to sleep with the head of the bed flat B. uAssessing for other signs and symptoms of paroxysmal nocturnal dyspnea/u C. Reassure the patient that this is normal aging Rationale: Awakening with shortness of breath suggests paroxysmal nocturnal dyspnea; further assessment is needed. ________________________________________ 9. When assessing tactile fremitus, the nurse recalls that it is normal to feel tactile fremitus most intensely over which location? A. Over the lung apices B. uBetween the scapulae/u C. Over the lower anterior chest Rationale: Tactile fremitus is most intense between the scapulae (near major airways). ________________________________________ 10. The nurse is reviewing the technique of palpating for tactile fremitus with a new graduate. Which statement by the graduate nurse reflects a correct understanding of tactile fremitus? Tactile fremitus: A. Is a palpable vibration caused by blood flow B. uIs caused by sounds generated from the larynx/u C. Is always absent in healthy lungs Rationale: Tactile fremitus is caused by laryngeal vibrations transmitted through the bronchial tree. ________________________________________ 11. Tactile Fremitus is what? A. Audible crackles B. uPalpable vibration/u C. Visual chest asymmetry Rationale: Fremitus is a palpable vibration felt on the chest wall during speech. ________________________________________ 12. During percussion, the nurse knows that a dull percussion note elicited over a lung lobe most likely results from: A. uIncreased density of lung tissue/u B. Hyperinflation C. Normal air-filled lung Rationale: Dullness indicates increased tissue density (e.g., pneumonia, atelectasis, tumor).
