Correct Answer: B

Rationale: The nurse's priority action after applying the surgical dressing is to assess the surgical incision for signs of complications. This includes checking for any signs of infection, excessive bleeding, or other complications related to the surgical site. Early detection of such complications is crucial for ensuring proper healing and preventing serious complications. Once the assessment is done and any issues are addressed, the nurse can proceed with documenting the dressing change, providing instructions to the patient about wound care, and ensuring that the dressing is securely and correctly applied.

Correct Answer: C

Rationale: The described clinical presentation of a yellowish-white spot on the cornea with a ring of inflammation, along with branching, filamentous opacities extending from the corneal lesion, is highly suggestive of fungal keratitis. Fungal keratitis is commonly caused by filamentous fungi such as Fusarium and Aspergillus species. The characteristic finding of branching, filamentous opacities seen on slit-lamp examination is classic for fungal infections of the cornea. It is important to promptly diagnose and treat fungal keratitis since delayed or inadequate management can result in vision-threatening complications.

Correct Answer: C

Rationale: Following surgical fixation of a tibial shaft fracture with an intramedullary nail, healthcare providers should monitor for the development of fat embolism syndrome (FES) in the immediate postoperative period. FES is a serious complication that occurs when fat droplets from the bone marrow enter the bloodstream and cause respiratory and neurological symptoms. Clinical manifestations of FES may include dyspnea, tachypnea, petechial rash, altered mental status, and hypoxemia. Prompt recognition and treatment are essential in managing fat embolism syndrome to prevent serious complications such as respiratory failure and neurological deficits. Monitoring for signs and symptoms of FES is crucial in the postoperative care of patients undergoing surgical fixation of long bone fractures.

Correct Answer: A

Rationale: The recommended position for a conscious patient experiencing an acute asthma exacerbation is the High-Fowler's position. This position involves the patient sitting upright or almost upright at about a 90-degree angle. The High-Fowler's position helps improve ventilation by expanding the lungs and maximizing airflow in and out of the airways. It also reduces the work of breathing in patients with asthma by allowing gravity to assist in moving air in and out of the lungs more easily. Additionally, this position can help alleviate shortness of breath and improve oxygenation in patients experiencing an asthma exacerbation.

Correct Answer: C

Rationale: In the early stages of multiple myeloma (MM), abnormal values are often seen in the levels of immunoglobulins. This is due to the abnormal proliferation of plasma cells in the bone marrow, leading to overproduction of monoclonal immunoglobulins (M proteins). These abnormal immunoglobulins can be detected in blood tests and are a key diagnostic feature of MM. Changes in red blood cells, white blood cells, and platelets are not typically early indicators of multiple myeloma.
