The nurse is assessing a newly admitted medical patient and notes there is a depression in the lower portion of the patient's sternum. This patient's health record should note the presence of what chest deformity?
Correct Answer: B
Rationale: The correct answer is B: A funnel chest. A funnel chest, also known as pectus excavatum, is characterized by a depression in the lower portion of the sternum. This deformity causes the chest to appear sunken or caved in. The other choices are incorrect because: A) A barrel chest is associated with COPD and is characterized by an increased anterior-posterior diameter of the chest. C) A pigeon chest, also known as pectus carinatum, is characterized by a protrusion of the sternum and ribs. D) Kyphoscoliosis is a combination of kyphosis and scoliosis, involving both a curvature of the spine and rotation of the vertebrae.
