Which of these statements is trueregarding the vertebra prominens

Which of these statements is trueregarding the vertebra prominens? The vertebra prominens is:a.The spinous process of C7.b.Usually nonpalpable in most individuals.c.Opposite the interior border of the scapula.d.Located next to the manubrium of the sternum.

ANS: AThe spinous process of C7 is the vertebra prominens and is the most prominent bony spur protruding at the base of the neck. Counting ribs and intercostal spaces on the posterior thorax is difficult because of the muscles and soft tissue. The vertebra prominens is easier to identify and is used as a starting point in counting thoracic processes and identifying landmarks on the posterior chest.DIF:Cognitive Level: Remembering (Knowledge)REF: p. 414MSC: Client Needs: General

2.When performing a respiratory assessment on a patient, the nurse notices a costal angle of approximately 90 degrees. This characteristic is:a.Observed in patients with kyphosis.b.Indicative of pectus excavatum.c.A normal finding in a healthy adult.d.An expected finding in a patient with a barrel chest.

ANS: CThe right and left costal margins form an angle where they meet at the xiphoid process. Usually, this angle is 90 degrees or less. The angle increases when the rib cage is chronically overinflated, as in emphysema.DIF:Cognitive Level: Understanding (Comprehension)REF: p. 414MSC: Client Needs: Safe and Effective Care Environment: Management of Care

3.When assessing a patient’s lungs, the nurse recalls that the left lung:a. Consists of two lobes. b. Is divided by the horizontal fissure. c. Primarily consists of an upper lobe on the posterior chest.

d.Is shorter than the right lung because of the underlying stomach.

ANS: AThe left lung has two lobes, and the right lung has three lobes. The right lung is shorter than the left lung because of the underlying liver. The left lung is narrower than the right lung because the heart bulges to the left. The posterior chest is almost all lower lobes.DIF:Cognitive Level: Remembering (Knowledge)REF: p. 415MSC: Client Needs: General

4.Which statement about the apices of the lungs is true? The apices of the lungs:a.Are at the level of the second rib anteriorly.b.Extend 3 to 4 cm above the inner third of the clavicles.c.Are located at the sixth rib anteriorly and the eighth rib laterally.d.Rest on the diaphragm at the fifth intercostal space in the midclavicular line (MCL).

ANS: BThe apex of the lung on the anterior chest is 3 to 4 cm above the inner third of the clavicles. On the posterior chest, the apices are at the level of C7.DIF:Cognitive Level: Remembering (Knowledge)REF: p. 415MSC: Client Needs: General5.During an examination of the anterior thorax, the nurse is aware that the trachea bifurcates anteriorly at the…………………..
