Correct Answer: C

Rationale: In a patient with ARDS who is experiencing refractory hypoxemia despite maximal ventilatory support and prone positioning, the use of extracorporeal membrane oxygenation (ECMO) is a potentially life-saving adjunctive therapy. ECMO works by providing temporary support for gas exchange outside the body, allowing the lungs to rest and heal while providing adequate oxygenation and carbon dioxide removal. The use of ECMO has been associated with improved oxygenation and reduced mortality in severe cases of ARDS, especially in patients who fail conventional therapies. High-frequency oscillatory ventilation (HFOV) has not consistently shown mortality benefit in ARDS, continuous renal replacement therapy (CRRT) is not directly indicated for hypoxemia in ARDS, and inhaled nitric oxide (iNO) has shown limited benefit in improving oxygenation in ARDS without a clear impact on mortality.

Correct Answer: A

Rationale: Nicotine, a substance found in cigarettes, is known to have harmful effects on pregnancy. Smoking during pregnancy can lead to numerous complications, one of which is the increased risk of delivering a low birth weight infant. Low birth weight infants are born weighing less than 5.5 pounds (2.5 kilograms) and are at a higher risk of various health issues, developmental delays, and even mortality. Therefore, Nurse Emma advised the patient to quit smoking to reduce the risk of having a low birth weight infant.

Correct Answer: C

Rationale: The APCAR (Appearance, Pulse, Grimace, Activity, Respiration) score is used to evaluate a newborn's condition in the first few minutes after birth. This assessment typically occurs within the first 1 to 3 minutes after the baby is born. The score helps healthcare providers quickly assess the baby's overall well-being and determine if any immediate interventions or further monitoring are necessary.

Correct Answer: B

Rationale: Nursing interventions should be aimed at addressing the mother's needs for psychological security. Hyper vigilance and excessive worry about her child's safety indicate a lack of security in her mind. By providing support, reassurance, and education, nurses can help the mother feel more secure in her role as a parent and reduce her feelings of anxiety and distress. Establishing trust and building a therapeutic relationship can also contribute to enhancing the mother's psychological security and well-being.

Correct Answer: A

Rationale: The clinical presentation of gross hematuria, flank pain, palpable abdominal mass, along with imaging findings of a large heterogeneous renal mass with necrosis and calcifications are highly suggestive of renal cell carcinoma (RCC). RCC is the most common type of kidney cancer in adults. The presence of necrosis and calcifications are characteristic features of RCC. Imaging modalities such as CT scans or MRI can confirm the diagnosis by showing the typical features of RCC, including a solid mass with areas of necrosis and calcifications. It is important to further evaluate this patient, likely with a biopsy, to confirm the diagnosis and determine the extent of the disease for appropriate management.
