respiratory prepU 2021 questions with correct answers to score A+

Which of the following statements would not be considered an appropriate intervention for a patient with an ET tube? Routine cuff deflation is recommended Routine cuff deflation is not recommended because of the increased risk for aspiration and hypoxia. The cuff is deflated before the endotracheal tube is removed. Cuff pressures should be checked every 6 to 8 hours. Humidified oxygen should always be introduced through the tube. A client undergoes a tracheostomy after many failed attempts at weaning him from a mechanical ventilator. Two days after tracheostomy, while the client is being weaned, the nurse detects a mild air leak in the tracheostomy tube cuff. What should the nurse do first? Suction the client, withdraw residual air from the cuff, and reinflate it. 00:10 01:46 The nurse assesses a patient with a heart rate of 42 and a blood pressure of 70/46. What type of hypoxia does the nurse determine this patient is displaying? Circulatory hypoxia A patient with emphysema is placed on continuous oxygen at 2 L/min at home. Why is it important for the nurse to educate the patient and family that they must have No Smoking signs placed on the doors? Oxygen supports combustion A client abruptly sits up in bed, reports having difficulty breathing and has an arterial oxygen saturation of 88%. Which mode of oxygen delivery is most likely to reverse these manifestations? Nonrebreather mask A client with COPD has been receiving oxygen therapy for an extended period. What symptoms would be indicators that the client is experiencing oxygen toxicity? Select all that apply. • Substernal pain • Dyspnea • Fatigue The nurse is caring for a patient with an endotracheal tube (ET). Which of the following nursing interventions is contraindicated? Deflating the cuff routinely The client is postoperative for a total laryngectomy and has recovered from anesthesia. The client's respirations are 32 breaths/minute, blood pressure is 102/58, and pulse rate is 104 beats/minute. Pulse oximetry is 90%. The client is receiving humidified oxygen. To aid in the client's respiratory status, the nurse places the client in Semi-Fowlers The nurse is using an in-line suction kit to suction a patient who is intubated and on a mechanical ventilator. What benefits does inline suction have for the patient? (Select all that apply.) • Decreases hypoxemia • Decreases patient anxiety • Sustains positive end expiratory pressure (PEEP) Which type of ventilator has a pre-sent volume of air to be delivered with each inspiration? Volume cycled With volume-cycled ventilation, the volume of air to be delivered with each inspiration is present. Negative pressure ventilators exert a negative pressure on the external chest. Time-cycled ventilators terminate or control inspiration after a preset time. When the pressure-cycled ventilator cycles on, it delivers a flow of air (inspiration) until it reaches a present pressure, and then cycles off, and expiration occurs passively. Which ventilator mode provides full ventilatory support by delivering a present tidal volume and respiratory rate? Assist-control Assist-control ventilation provides full ventilator support by delivering a preset tidal volume and respiratory rate. Intermittent mandatory ventilation (IMV) provides a combination of mechanically assisted breaths and spontaneous breaths. SIMV delivers a preset tidal volume and number of breaths per minute. Between ventilator-delivered breaths, the patient can breathe spontaneously with no assistance from the ventilator for those extra breaths. A patient is brought into the emergency department with carbon monoxide poisoning after escaping a house fire. What should the nurse monitor this patient for? Anemic hypoxia Anemic hypoxia is a result of decreased effective hemoglobin concentration, which causes a decrease in the oxygen-carrying capacity of the blood. It is rarely accompanied by hypoxemia. Carbon monoxide poisoning, because it reduces the oxygen-carrying capacity of hemoglobin, produces similar effects but is not strictly anemic hypoxia, because hemoglobin levels may be normal.
