The nurse provides dietary education for a patient diagnosed with GERD. In reviewing correct food choices, which food choice by the patient would require further instruction by the nurse?

A. Place the client in Trendelenburg position: Trendelenburg (head-down) position can increase intracranial pressure and worsen cardiovascular strain. It is contraindicated in hypertensive emergencies and is not an appropriate intervention for acute severe hypertension.

B. Encourage the client to ambulate: Physical activity can exacerbate elevated blood pressure and increase the risk of complications such as stroke or myocardial infarction. Bed rest or minimal activity is recommended until blood pressure is controlled.

C. Administer prescribed antihypertensive IV: A BP of 210/120 mmHg with severe headache indicates a hypertensive emergency requiring immediate intervention. Administering IV antihypertensives as prescribed allows rapid, controlled reduction of blood pressure to prevent end-organ damage, making this the priority action.

D. Provide a high-sodium diet: High sodium intake would worsen hypertension and is contraindicated in hypertensive emergencies. Dietary modifications are long-term interventions and not appropriate as an acute management strategy.

A. A sputum culture is performed to assess the client's immune response to TB infection: Immune response is evaluated using tests such as the tuberculin skin test (TST) or interferon-gamma release assays (IGRAs), not sputum cultures. Sputum culture does not measure immunity.

B. A sputum culture is used to monitor the effectiveness of TB treatment and evaluate disease progression: While serial sputum cultures can track treatment response over time, the primary purpose of the initial culture is to identify the causative organism. Monitoring treatment is secondary.

C. A sputum culture is used to detect the presence of TB bacteria in the lungs: The sputum culture allows growth and identification of Mycobacterium tuberculosis from expectorated material, confirming the diagnosis. It is the gold standard for detecting active pulmonary TB.

D. A sputum culture is performed to assess lung function and determine the severity of TB infection: Lung function is assessed via pulmonary function tests or imaging, not sputum cultures. Culture results indicate bacterial presence, not the functional capacity of the lungs.
