Which of the following would not be an appropriate nursing intervention when preparing to administer a blood transfusion?

A) "Western Blot test":
. The Western Blot test is typically used to confirm HIV infection after a positive enzyme-linked immunosorbent assay (ELISA). This test is not relevant for diagnosing pneumonia, which is the most likely cause of this patient's symptoms. The patient's presentation — including dyspnea on exertion, cough with green sputum, fever, fatigue, and bilateral consolidation on the chest X-ray — points to a respiratory infection (likely pneumonia) rather than an HIV-related issue.

B) "Initiation of broad-spectrum antibiotics":
. The patient's symptoms, including dyspnea, cough with green sputum, fever, fatigue, and bilateral consolidation on chest X-ray, strongly suggest community-acquired pneumonia (CAP) or hospital-acquired pneumonia (HAP). In either case, broad-spectrum antibiotics are indicated to cover a wide range of potential bacterial pathogens, especially in older adults or those with comorbidities who may be at risk for more severe infections. Immediate treatment with antibiotics is necessary to prevent complications such as respiratory failure or sepsis. Once cultures and sensitivities are obtained, the antibiotics may be adjusted based on the specific pathogen.

C) "Initiation of Isoniazid and Rifampin":
. Isoniazid and Rifampin are used to treat tuberculosis (TB), but this patient’s symptoms do not indicate TB. The patient is experiencing acute respiratory symptoms, including fever, cough with sputum production, and consolidation on chest X-ray, which are more indicative of pneumonia than of tuberculosis. Although TB could present similarly, additional testing such as a TB skin test (TST) or sputum culture for acid-fast bacilli (AFB) would be necessary before initiating antitubercular therapy. The priority intervention here is antibiotic treatment for bacterial pneumonia.

D) "Antiretroviral therapy":
. Antiretroviral therapy (ART) is used to treat HIV, but there is no indication that this patient has HIV. The symptoms presented — dyspnea, productive cough, fever, and bilateral consolidation on chest X-ray — are more consistent with an acute bacterial infection such as pneumonia rather than an HIV-related complication. ART would only be appropriate if the patient were known to have HIV and developed an opportunistic infection; however, this patient's presentation suggests a primary respiratory infection, not an HIV-related issue.

A) "Complete blood count (CBC)":
. A CBC can provide important information about the patient's overall health, including potential signs of infection, anemia, or other underlying conditions. However, in the context of acute neurological symptoms such as left-sided weakness, CT scan is the priority test because it will help quickly determine if there is an acute neurological event, such as a stroke or hemorrhage. While a CBC might be useful later to assess for underlying
conditions or potential causes, it is not the first test to perform in this scenario.

B) "Electroencephalogram (EEG)":
. An EEG is primarily used to diagnose and assess seizure activity or epileptic disorders. While seizures can cause neurological deficits, the patient's sudden onset of left-sided weakness is more suggestive of a stroke, not a seizure. The priority is to rule out stroke with a CT scan, not to assess for seizures with an EEG.

C) "Computed tomography (CT) scan":
. A CT scan is the first diagnostic test to perform in patients with acute neurological deficits such as sudden-onset weakness, especially when a stroke is suspected. A CT scan can quickly detect if the cause is an ischemic stroke (lack of blood flow due to a clot) or a hemorrhagic stroke (bleeding in the brain). Time is critical in the management of stroke, as early intervention with treatments like tPA (tissue plasminogen activator) for ischemic stroke can greatly improve outcomes. The CT scan can help determine if the patient is a candidate for thrombolysis or if other interventions are needed.

D) "Chest radiograph (chest x-ray)":
. While a chest x-ray can be useful for diagnosing respiratory issues, such as pneumonia or congestion, it is not helpful in evaluating the cause of acute neurological symptoms like left-sided weakness. The priority test is a CT scan to evaluate the brain and rule out conditions like stroke or hemorrhage, not a chest x-ray.
