When assessing the elderly patient, the nurse observes that the anterior to posterior width is the same as the transverse width of the chest. When documenting her findings, she describes this as:

A) Lordosis: This term specifically refers to an exaggerated inward curvature of the spine, particularly in the cervical or lumbar regions. When the nurse observes an exaggerated cervical curve, lordosis is the correct term to use for documentation, indicating a deviation from the normal spinal alignment.

B) Scoliosis: This condition is characterized by an abnormal lateral curvature of the spine. It does not apply to the observation of an exaggerated cervical curve and would not be appropriate for this finding.

C) Kyphosis: This term denotes an excessive outward curvature of the thoracic spine, often leading to a hunchback appearance. Since the assessment focuses on the cervical region, kyphosis would not accurately describe an exaggerated cervical curve.

D) Normal curve: This term refers to the expected, healthy curvature of the spine. Documenting an exaggerated curve as "normal" would be misleading and does not accurately reflect the observed condition. The nurse should document the finding as lordosis to convey the specific abnormality noted.

A) The patient has asthma: While asthma can lead to respiratory symptoms and issues, it is not typically associated with clubbing of the fingernails. Asthma primarily affects airway constriction and inflammation, rather than causing the long-term changes in nail morphology seen with clubbing.

B) The patient has cardiovascular disease: Although some cardiovascular conditions can lead to clubbing, it is more commonly associated with chronic lung diseases. Cardiovascular disease might cause other signs or symptoms, but clubbing alone is not a definitive indicator of this condition.

C) The patient has emphysema: Emphysema, a type of chronic obstructive pulmonary disease (COPD), is characterized by the destruction of lung tissue and impaired airflow. While it can contribute to hypoxemia, clubbing is not a common finding specifically associated with emphysema.
D) The patient has chronic hypoxemia: Clubbing of the fingernails is a classic sign of chronic hypoxemia, often resulting from long-term respiratory conditions like COPD, interstitial lung disease, or lung cancer. It indicates a prolonged lack of oxygen in the blood, leading to changes in the nail bed and digit shape. Given the patient's long smoking history, chronic hypoxemia is the most likely explanation for this finding.
