A patient with a displaced femoral neck fracture is scheduled for surgical intervention. Which surgical procedure is most appropriate for this type of fracture?

Correct Answer: B

Rationale: For a displaced femoral neck fracture, the most appropriate surgical procedure is usually an open reduction and internal fixation (ORIF). This procedure involves making an incision to reposition the fractured bone fragments and securing them in place with screws or other fixation devices. ORIF allows for better alignment of the fracture, which is crucial for proper healing and minimizing the risk of complications like avascular necrosis or nonunion. Closed reduction and internal fixation (CRIF) may not be as effective for displaced femoral neck fractures due to the complex nature of the fracture and the need for precise realignment and stability provided by an open surgical approach. External fixation is less commonly used for femoral neck fractures and is typically reserved for certain specific cases where internal fixation is not feasible. Closed reduction alone is unlikely to provide adequate stability for a displaced femoral neck fracture and is generally not recommended as the primary surgical treatment for this type of injury.

Correct Answer: A

Rationale: Lactulose is the most effective nursing intervention in preventing and managing hepatic encephalopathy in patients with cirrhosis. Lactulose works by promoting the elimination of ammonia in the colon through its laxative effect, thereby reducing ammonia levels in the blood. High ammonia levels are associated with the development of hepatic encephalopathy. By administering lactulose as prescribed, nurses can help reduce the risk of encephalopathy and manage symptoms effectively. Monitoring serum ammonia levels is important in assessing the effectiveness of lactulose therapy, but administering lactulose is the primary nursing intervention in this situation. Dietary protein restriction is also commonly recommended; however, lactulose administration is the most vital intervention in this scenario. Additionally, encouraging increased fluid intake is important for overall liver health but is not as specific to preventing and managing hepatic encephalopathy as administering lactulose.

Correct Answer: D

Rationale: The patient is presenting with symptoms and laboratory findings consistent with a paraneoplastic syndrome related to Hodgkin lymphoma. In this case, the fever, chills, generalized malaise, pancytopenia, circulating Reed-Sternberg cells, and bone marrow involvement are all indicative of a paraneoplastic syndrome associated with Hodgkin lymphoma. Paraneoplastic syndromes are a group of disorders that are triggered by an abnormal immune response to a neoplasm, such as Hodgkin lymphoma, leading to various systemic manifestations.

Correct Answer: C

Rationale: Total Parenteral Nutrition (TPN) is a method of providing nutrition to patients who cannot or should not obtain their nutrition through regular oral intake. The primary goals of TPN include promoting weight gain, improving nutritional status, maintaining muscle mass, and establishing nitrogen balance. These goals are crucial to support the overall health and well-being of the patient receiving TPN. Enhancing the healing process is an important aspect of TPN as well, but it is not considered one of the primary goals as weight gain, nutritional status, muscle mass, and nitrogen balance are typically the immediate priorities when administering TPN.

Correct Answer: C

Rationale: If the nurse notices that the patient's arms are not adequately padded while positioning for surgery, the nurse should immediately take action to prevent pressure injuries. Applying soft padding to the patient's arms will help distribute the pressure more evenly, reducing the risk of skin breakdown and potential harm to the patient during the surgical procedure. It is essential to prioritize the patient's safety and comfort in such situations. Simply proceeding with the positioning as planned could lead to complications, so addressing the inadequate padding promptly is the appropriate course of action.

Correct Answer: D

Rationale: The aim of human sciences, including nursing as a human science, is to make meaningful interpretations of the phenomena being studied. Unlike natural sciences that may focus on prediction, control, or seeking causal explanations, the human sciences aim to understand and interpret human experiences, behaviors, and relationships in a meaningful way. In nursing, this involves not only understanding the biological aspects of health and illness but also considering the holistic and humanistic aspects of care, such as emotions, values, beliefs, and perceptions. By making meaningful interpretations, nurses can better understand their patients and provide individualized and patient-centered care.

Correct Answer: C

Rationale: Rabies is a viral disease that affects the central nervous system. It is primarily transmitted through the bite of an infected animal, such as dogs, bats, raccoons, and foxes. The causative agent of rabies is the rabies virus, specifically from the genus Lyssavirus. Once the virus enters the body, it spreads through the nervous system to the brain, leading to severe neurological symptoms and, if left untreated, is almost always fatal. This is why prompt medical attention and vaccination following an animal bite are crucial in preventing the development of rabies in humans.

Correct Answer: B

Rationale: Clozapine is an atypical antipsychotic medication primarily used in the treatment of schizophrenia. One of the positive effects of Clozapine is the reduction of psychotic symptoms experienced by the patient, such as hallucinations (not hearing loss). Clozapine is effective in managing both positive symptoms (hallucinations, delusions, disorganized thinking) and negative symptoms (apathy, social withdrawal, lack of motivation) of schizophrenia. It is known for its efficacy in reducing hallucinations and other psychotic symptoms, helping the patient to lead a more stable and functional life.

Correct Answer: D

Rationale: Ensuring the availability of emergency equipment and resuscitation medications is crucial to prioritize patient safety during a transesophageal echocardiogram (TEE) procedure. TEE involves inserting a specialized probe (transducer) into the esophagus to obtain detailed images of the heart. While complications during TEE are rare, they can include adverse reactions to sedation, esophageal injury, arrhythmias, or other cardiac events. By having emergency equipment and resuscitation medications readily available, the healthcare team can respond promptly to any unforeseen complications or emergencies that may arise during the procedure, ensuring optimal patient safety. Placing the patient in a supine position, providing sedation, and advising the patient to fast before the procedure are important aspects of the TEE process; however, ensuring emergency preparedness takes precedence in prioritizing patient safety during the procedure.
