A nurse is caring for a client 1 day postoperative who has developed atelectasis. Which of the following manifestations is an expected finding for this condition?

A) Hypoxemia:
This is the correct answer. Atelectasis, which is the collapse or incomplete inflation of the lung, can lead to impaired gas exchange and subsequent hypoxemia. As lung volume decreases due to collapse, ventilation-perfusion (V/Q) mismatch occurs, resulting in decreased oxygenation of arterial blood. Hypoxemia is a common finding in individuals with atelectasis and may manifest as decreased oxygen saturation levels on pulse oximetry or arterial blood gas analysis.

B) Apnea:
Apnea, defined as the cessation of breathing, is not typically associated with atelectasis. While atelectasis can contribute to respiratory compromise and may result in respiratory distress, including tachypnea or increased work of breathing, it does not usually lead to complete cessation of breathing.

C) Pleural effusion:
A pleural effusion is the accumulation of fluid in the pleural space surrounding the lungs. While pleural effusion may occur concurrently with atelectasis, it is not an expected finding specifically associated with atelectasis itself. Pleural effusion may cause respiratory symptoms such as dyspnea or chest pain but is not a primary manifestation of atelectasis.

D) Dysphagia:
Dysphagia, or difficulty swallowing, is unrelated to atelectasis. While dysphagia can occur as a result of various conditions affecting the esophagus or neurological control of swallowing, it is not a typical manifestation of atelectasis. Atelectasis primarily affects the lungs and respiratory function rather than swallowing function.

A) Lifestyle modification, including exercise, diet, and decreased smoking and alcohol intake:
This statement is accurate. Lifestyle modifications are essential components of hypertension management and are recommended as the first step in treatment. These modifications include regular physical activity, adopting a heart-healthy diet such as the DASH (Dietary Approaches to Stop Hypertension) diet, reducing sodium intake, limiting alcohol consumption, and quitting smoking. These changes can help lower blood pressure and reduce the risk of cardiovascular events.

B) Use of diuretic, beta-blocker, or ACE inhibitor to supplement lifestyle changes:
This statement is also accurate. If lifestyle modifications alone are insufficient to achieve blood pressure control, pharmacotherapy may be initiated. The choice of antihypertensive medications depends on various factors, including the individual's comorbidities, medication tolerance, and response to treatment. Diuretics, beta-blockers, and ACE inhibitors are commonly used as first-line agents in the management of hypertension, either as monotherapy or in combination with other drugs.

C) All of the above:
This statement is correct. The stepped-care approach to hypertension management involves a combination of lifestyle modifications and pharmacotherapy. Lifestyle changes are typically recommended as the initial step, followed by the addition of antihypertensive medications if necessary to achieve target blood pressure goals. Therefore, both lifestyle modifications and pharmacological interventions are integral components of the stepped-care approach.

D) A combination of antihypertensive drug classes to achieve desired control:
While this statement is true, it does not encompass all aspects of the stepped-care approach. The use of combination therapy with multiple antihypertensive drug classes may be necessary in some cases to achieve optimal blood pressure control. However, it is only one component of the broader treatment strategy, which also includes lifestyle modifications as the foundation of therapy. Therefore, while combination therapy is important, it does not fully represent the stepped-care approach on its own.
