A nurse is providing care to a client who has spent several weeks in the intensive care unit because of complications related to shock. What adverse psychological outcomes should the nurse educate the client about prior to transfer to the medical unit?

A) Computed tomography (CT) scan: A CT scan may provide detailed images of the heart and surrounding structures, but it is not typically the initial diagnostic test used to assess for cardiac tamponade. CT scans are often used in conjunction with other diagnostic tests but are not the first-line investigation for suspected tamponade.

B) Chest x-ray: While a chest x-ray may show signs of cardiac tamponade, such as an enlarged cardiac silhouette or evidence of fluid accumulation around the heart, it is not as sensitive or specific as other diagnostic tests, particularly in the acute setting. Chest x-rays may be obtained as part of the diagnostic workup, but they are not the first-line test for suspected tamponade.

C) Echocardiogram: An echocardiogram is the most appropriate initial diagnostic test for suspected cardiac tamponade. It provides real-time imaging of the heart and can detect pericardial effusion, collapse of the right atrium and ventricle during diastole (diastolic collapse), and signs of hemodynamic compromise. Echocardiography allows for rapid assessment at the bedside and can guide immediate management decisions.

D) Electrocardiogram (ECG): While an electrocardiogram may show nonspecific changes in cardiac tamponade, such as low-voltage QRS complexes or electrical alternans, it is not as sensitive or specific as an echocardiogram for diagnosing tamponade. ECG findings may support the diagnosis but are not typically the first-line test for suspected tamponade.

A. Completing hourly endotracheal suctioning: Hourly endotracheal suctioning is not typically indicated for a client with increased intracranial pressure (ICP). Frequent suctioning can lead to increased intrathoracic pressure and potentially compromise venous return, which may further elevate ICP. Suctioning should be performed as needed to maintain airway patency while minimizing the risk of increasing ICP.

B. Ensuring proper ventriculostomy transducer levels: Ensuring proper ventriculostomy transducer levels is important for accurate measurement of intracranial pressure (ICP) but may not directly alleviate elevated ICP. Monitoring ICP through ventriculostomy allows for timely detection of changes in ICP, which can guide interventions to manage elevated pressure levels. However, it is not a direct intervention to reduce ICP.

C. Monitoring volume status: Monitoring volume status is important in managing a client with increased intracranial pressure (ICP) as both hypovolemia and hypervolemia can impact ICP. However, monitoring volume status alone does not directly address elevated ICP. Interventions to optimize volume status, such as fluid administration or diuresis, may be implemented based on assessment findings, but they should be done cautiously to avoid exacerbating cerebral edema or altering cerebral perfusion.

D. Elevating the head of the bed 15°: Elevating the head of the bed 15° (or higher) is a crucial intervention for managing a client with increased intracranial pressure (ICP). This position helps promote venous drainage from the brain, reducing venous congestion and intracranial pressure. Elevating the head of the bed also helps prevent cerebrospinal fluid (CSF) from pooling in the brain, which can further increase ICP. Placing the client in a semi-upright position is a standard practice in managing ICP and is recommended in various clinical guidelines.
