Correct Answer: D

Rationale: The correct position for a patient with a left-sided pleural effusion undergoing thoracentesis is sitting upright with the arms supported on an overbed table. This position helps increase lung expansion, allows fluid to collect at the lung bases, and expands the intercostal space making access to the pleural space easier. Placing the patient supine, in a high-Fowler's position, or on the right side with the left arm extended above the head could increase the work of breathing for the patient and complicate the thoracentesis procedure for the healthcare provider.

Correct Answer: C

Rationale: The most critical information to communicate to the healthcare provider in a patient diagnosed with both HIV and active TB disease is that the patient is receiving antiretroviral therapy for HIV infection. This is crucial because drug interactions can occur between antiretrovirals used to treat HIV infection and medications used to treat TB. By informing the healthcare provider about the antiretroviral therapy, potential interactions can be assessed and managed effectively to optimize patient care. The other data provided, such as the Mantoux test result, chest x-ray findings, and presence of blood-tinged mucus, are important clinical information but are expected in a patient with coexisting HIV and TB and do not directly impact potential drug interactions between antiretrovirals and TB medications.

Correct Answer: D

Rationale: The correct answer is Piperacillin/tazobactam (Zosyn). Early initiation of antibiotic therapy is crucial in cases of community-acquired pneumococcal pneumonia to reduce mortality. While providing symptomatic relief with medications like Codeine for cough, Guaifenesin for mucus clearance, and Acetaminophen for fever and pain is important, the priority should be to start antibiotic therapy to target the underlying infection. Piperacillin/tazobactam is an appropriate choice for treating severe community-acquired pneumonia caused by pneumococcal organisms.

Correct Answer: A

Rationale: In a patient with ALS, progressive muscle weakness is a significant issue. Assisting with active range of motion (ROM) exercises will help maintain muscle strength for as long as possible. Agitation and paranoia are not typically associated with ALS, making choice B incorrect. Giving muscle relaxants can further weaken muscles and depress respirations, worsening the condition, so choice C is inappropriate. Choice D is not directly related to the patient's physical condition and needs.

Correct Answer: B

Rationale: The correct answer is for the patient to report decreased exertional dyspnea. In idiopathic pulmonary arterial hypertension (IPAH), exertional dyspnea is a significant symptom indicating disease severity. Improvement in this symptom suggests that the medication, nifedipine, is effective in managing the condition. While nifedipine can affect blood pressure (choice A) and heart rate (choice C), these parameters are not specific indicators for monitoring IPAH improvement. Choice D, clear lung fields on the chest x-ray, does not directly correlate with the effectiveness of therapy for IPAH. Therefore, the most relevant assessment to monitor improvement in a patient with IPAH receiving nifedipine is a decrease in exertional dyspnea.
