Correct Answer: D

Rationale: A trimalleolar fracture is characterized by fractures involving the lateral malleolus (distal fibula), medial malleolus (distal tibia), and the posterior tubercle of the distal tibia. This fracture pattern results in instability of the ankle joint and is often associated with widening of the ankle mortise on X-ray. The deformity and swelling seen in this patient are indicative of a trimalleolar fracture and are typically caused by a high-energy injury, such as a forceful twisting motion. Treatment for trimalleolar fractures often involves surgical intervention to stabilize the ankle joint and restore normal function.

Correct Answer: B

Rationale: During pulmonary rehabilitation for COPD, smoking cessation should not be avoided but instead strongly encouraged. Smoking cessation is a crucial component in managing COPD and improving lung function. Continued smoking can exacerbate COPD symptoms and hinder the progress made through rehabilitation efforts. Therefore, it is essential for patients to quit smoking while undergoing pulmonary rehabilitation to maximize the benefits of the program and improve their overall lung health.

Correct Answer: A

Rationale: Acute respiratory distress syndrome (ARDS) is a serious and life-threatening condition characterized by rapid onset of respiratory failure, severe hypoxemia (low oxygen levels in the blood), and non-cardiogenic pulmonary edema. The hallmark of ARDS is severe hypoxemia that is difficult to correct even with high levels of supplemental oxygen. Patients with ARDS often require mechanical ventilation to maintain adequate oxygen levels. Severe cough with purulent sputum production, chest pain exacerbated by deep breathing, and productive cough with hemoptysis are not typical features of ARDS.

Correct Answer: D

Rationale: The prioritized nursing intervention in this situation should be assessing for the risk of harm to self or infant. It is crucial to ensure the safety of the postpartum client and her infant as depression can increase the risk of self-harm or harm to the newborn. By assessing for any potential risks, the nurse can take appropriate actions to prevent any harm and ensure the well-being of both the client and the infant. Once the assessment is completed, further interventions like encouraging participation in support groups, referring to a mental health professional, or administering medications can be considered based on the assessment findings.

Correct Answer: C

Rationale: Tetanus toxoid provides long-lasting active immunity. When a person is vaccinated with tetanus toxoid, their immune system is stimulated to produce antibodies against the tetanus toxin. These antibodies provide protection against tetanus infection by recognizing and neutralizing the toxin if the person is exposed to the bacteria that causes tetanus in the future. This active immune response can last for many years, providing ongoing protection against tetanus. However, booster doses are recommended every 10 years to maintain adequate levels of protection.
