The nurse is performing an admission assessment for a client with pyelonephritis who has urgency and burning while urinating. Which finding indicates an expected response when the nurse percusses the costovertebral angle?

Choice A Reason:
Observing for jugular vein distention while the client is flat in bed is incorrect because jugular vein distention is not directly related to orthopnea. Jugular vein distention may indicate increased central venous pressure, which can occur in conditions such as heart failure, but it is not specific to orthopnea, which is difficulty breathing while lying flat.
Choice B Reason:
Measuring the client's blood pressure when he is lying and standing is incorrect because measuring blood pressure in different positions (lying and standing) is used to assess for orthostatic hypotension, not orthopnea. Orthostatic hypotension refers to a drop-in blood pressure upon standing and is not directly related to difficulty breathing while lying flat.
Choice C Reason:
Asking the client how many pillows he sleeps on at night is correct because orthopnea is characterized by difficulty breathing while lying flat, often relieved by sitting up or propping oneself with pillows. Asking the client how many pillows he sleeps on at night provides valuable information about his sleeping position and potential orthopnea. Clients with orthopnea often need to sleep in a semi-upright position or with multiple pillows to alleviate breathing difficulties.
Choice D Reason:
Auscultating the client's breath sounds while he is supine is incorrect because auscultating the client's breath sounds while he is supine may provide information about lung sounds, but it does not specifically assess for orthopnea. Orthopnea refers to difficulty breathing while lying flat, and the assessment of breath sounds may not directly indicate this condition.

C. Chronic obstructive pulmonary disease (COPD): COPD is a chronic respiratory condition characterized by airflow limitation, typically caused by chronic bronchitis and/or emphysema. In COPD, the airways become narrowed and inflamed, leading to difficulty breathing. Over time, chronic hypoxia (low oxygen levels in the blood) can develop due to impaired gas exchange in the lungs. Chronic hypoxia can trigger compensatory mechanisms in the body, including vascular changes that result in clubbing of the nails. Therefore, clubbed nails can often be seen in individuals with COPD as a consequence of chronic tissue hypoxia.

D. Lung cancer: Lung cancer is a malignant tumor that arises from the cells of the lungs. It is often associated with long-term smoking, as in the case of this client. Lung cancer can impair lung function and compromise gas exchange, leading to chronic hypoxia. As with COPD, chronic hypoxia can induce vascular changes that result in clubbing of the nails. Therefore, clubbed nails can be a manifestation of advanced lung cancer, particularly in cases where chronic hypoxia is present due to impaired lung function.

E. Chronic bronchitis: Chronic bronchitis is a type of chronic obstructive pulmonary disease (COPD) characterized by inflammation and narrowing of the airways, leading to excessive mucus production and persistent cough. Similar to other forms of COPD, chronic bronchitis can result in chronic hypoxia due to impaired gas exchange in the lungs. The chronic hypoxia associated with chronic bronchitis can lead to vascular changes that cause clubbing of the nails over time. Therefore, individuals with chronic bronchitis may also exhibit clubbed nails as a consequence of chronic tissue hypoxia.
