How can the nurse help monitor effectiveness of therapy for the patient with a pneumothorax and chest-drainage system?

Correct Answer: C

Rationale: The nurse can help monitor the effectiveness of therapy for a patient with a pneumothorax and chest drainage system by auscultating lung sounds. Auscultation can provide information about the air movement within the lungs and any changes in lung sounds, such as decreased or absent breath sounds on the affected side, which may indicate improvement or deterioration in the patient's condition. By regularly assessing lung sounds, the nurse can track the progress of the therapy and make informed decisions about the patient's care and treatment plan. Palpating for crepitus, documenting sputum characteristics, and monitoring suction levels are important aspects of care but are not specifically focused on assessing the effectiveness of therapy for a pneumothorax.

Correct Answer: C

Rationale: Digoxin is a medication commonly used to treat heart failure and certain types of irregular heart rhythms. One of the therapeutic effects of digoxin is an improvement in cardiac output, leading to better tissue perfusion. As the heart's pumping ability improves, blood flow to the kidneys also increases, resulting in an increase in urine output. Therefore, an increase in urine output is a positive indication that digoxin is effective for the patient. Monitoring urine output can be a valuable way for nurses to assess the response to digoxin therapy and the overall cardiac function of the patient.

Correct Answer: C

Rationale: Cerebral palsy is the most common permanent disability in childhood among the options provided. It is a group of disorders that affect movement and muscle coordination due to damage or abnormal development in the brain. Cerebral palsy can occur before, during, or shortly after birth, and it is a lifelong condition that impacts a child's ability to move, maintain balance, and posture. Scoliosis, muscular dystrophy, and developmental dysplasia of the hip (DDH) are also significant conditions that can lead to disabilities in children, but they are not as prevalent as cerebral palsy in terms of permanent disabilities in childhood.

Correct Answer: B
