A patient with a fractured forearm had the fracture reduced and a fiberglass cast placed on the extremity. The orthopedic surgeon orders a postreduction study. The original kVp was 65 kVp. Which one of the following kVp factors should be selected for the postreduction study?

Which of the following assessment findings is an early indicator of acute hypoxemic respiratory failure?

A patient’s ventilator settings are adjusted to treat hypoxemia. The FiO2 is increased from 60% to 70%, and the positive end-expiratory pressure is increased from 10 to 15 cm H2O. Shortly after these adjustments, the nurse notes that the patient’s blood pressure drops from 120/76 mm Hg to 90/60 mm Hg. What is the most likely cause of this decrease in blood pressure?

Which assessment data indicate to the nurse the client diagnosed with acute respiratory failure (ARF) has experienced a complication secondary to the ventilator?

A patient is being mechanically ventilated in the synchronized intermittent mandatory ventilation mode at a rate of 4 breaths/min. Spontaneous respirations are 12 breaths/min. The patient receives a dose of morphine sulfate, and now respirations decrease to 4 breaths/min. What adjustments may need to be made to the patient’s ventilator settings?

High FiO₂ >60% for >48 hours increases risk for which pathophysiology?

A patient presents with chest trauma from a motor vehicle accident. Upon assessment, the nurse documents that the patient is complaining of dyspnea, shortness of breath, tachypnea, and tracheal deviation to the right. In addition, the patient’s tongue is blue-gray. Based on this assessment data, what additional assessment findings would the nurse expect to find?

A 59-year-old patient with a history of DVT suddenly develops dyspnea, chest pain, and hypotension (BP 78/50). ECG shows sinus tachycardia. ABG: pH 7.30, PaO₂ 55, PaCO₂ 49. The patient is already receiving O₂ by NRB mask.  Which intervention is the nurse’s immediate priority? 

A patient with acute respiratory failure is prepared for endotracheal intubation. The nurse preoxygenates the patient with 100% O₂ via bag-valve mask. Which action is the priority if SpO₂ drops below 92% during the attempt?

Select ALL appropriate uses of radiation in leukemia care.
