The nurse administers prescribed therapies for a patient with cor pulmonale and right-sided heart failure. Which assessment would best evaluate the effectiveness of the therapies?

Correct Answer: A

Rationale: To evaluate the effectiveness of therapies for cor pulmonale and right-sided heart failure, observing for distended neck veins would be the most appropriate assessment. Cor pulmonale is characterized by right ventricular failure due to pulmonary hypertension, leading to clinical manifestations such as peripheral edema, jugular venous distention, and right upper-quadrant abdominal tenderness. These signs indicate increased central venous pressure and right heart strain, which can be assessed by observing for distended neck veins. Auscultating for crackles in the lungs is more indicative of left-sided heart failure rather than right-sided heart failure. Heaves or thrills over the heart are not typically associated with cor pulmonale. Reviewing hemoglobin and hematocrit values may show elevations due to chronic hypoxemia and polycythemia in cor pulmonale, but these values alone do not directly evaluate the immediate effectiveness of the prescribed therapies on the patient's condition.

Correct Answer: B

Rationale: The correct action for the nurse to take in preparing a patient for a thoracentesis is to position the patient sitting upright on the edge of the bed and leaning forward. This position helps fluid accumulate at the lung bases, making it easier to locate and remove. Sedation is not usually required for a thoracentesis, so starting an IV line for sedative drugs is unnecessary. Additionally, there are no restrictions on oral intake before the procedure since the patient is not sedated or unconscious. A large collection device to hold 2 to 3 liters of pleural fluid at one time is excessive as usually only 1000 to 1200 mL of pleural fluid is removed to avoid complications like hypotension, hypoxemia, or pulmonary edema. Therefore, the correct choice is to position the patient upright for the procedure.

Correct Answer: D

Rationale: The correct answer is, 'I will call the health care provider right away if I develop a fever.' It is crucial for patients who have undergone a lung transplant to be vigilant about any signs of infection or rejection. A low-grade fever can be an early indicator of such complications, requiring immediate medical attention. While annual follow-up visits are necessary, they are not sufficient for monitoring acute changes in health post-transplant. Stopping prednisone abruptly can lead to rejection and should only be done under healthcare provider guidance. Feeling short of breath with exercise should be reported as it can indicate potential issues. Recognizing and addressing symptoms promptly is key to successful post-transplant care, and in this case, calling the healthcare provider immediately for a fever is the most appropriate action.

Correct Answer: B

Rationale: In a patient with probable bacterial pneumonia and sepsis, the priority intervention is to obtain blood cultures from two sites before initiating antibiotic therapy. This is crucial to identify the causative organism and guide appropriate antibiotic treatment. Administering antibiotics without obtaining cultures first can interfere with accurate results. Performing a chest x-ray and administering acetaminophen can be done after obtaining blood cultures as they are important but not as urgent as identifying the causative organism in sepsis.

Correct Answer: A

Rationale: Culture is a complex phenomenon that includes attitudes, beliefs, self-definitions, norms, roles, and values learned from birth through the processes of language acquisition and socialization. It is not biologically or genetically determined, but rather acquired through social interactions. The correct answer, 'Learned through language acquisition and socialization,' aligns with the understanding that culture is a learned behavior. Choices B, C, and D are incorrect because culture is not genetically determined, nonspecific, or biologically based on physical characteristics. Understanding that culture is acquired through language and socialization is essential for healthcare providers to provide culturally competent care.
