D) Obtain an ABG sample and send it to the lab before securing the ET. - Answer-C) Auscultate the lungs for symmetrical lung sounds. 4. Examples of medications with positive inotropic effect include all of the following EXCEPT: A) Dopamine B) Digitalis-like drugs C) B-adrenergic blockers D) Calcium sensitizers. - Answer-C) B-adrenergic blockers 5. Which of the following statements is WRONG about central venous pressure (CVP)? A) It increases in cases of hypovolemia. B) It increases in cases of hypervolemia. C) It increases in patients with right ventricular failure. D) It can be measured using the proximal port of the pulmonary artery catheter. - Answer-A) It increases in cases of hypovolemia. 6. The nurse notes thick, white respiratory secretions from a patient who is receiving mechanical ventilation. Which intervention will be most effective in resolving this problem? A) Increase fluid intake to loosen the secretion. B) Suction the patient every hour even after removal of the secretions. C) Reposition the patient every 4 hours. D) Instill 5 mL of sterile saline into the endotracheal tube (ET) before suctioning. - Answer-A) Increase fluid intake to loosen the secretion. 7. The flat wave on the following Pulmonary artery pressure waveform is: A) An indication of deflated balloon. B) An indication of overinflated balloon. C) Indicates complete coronary artery occlusion and MI. D) A normal expected change of the waveform as we inflate the balloon. - Answer-B) An indication of overinflated balloon. 8.

Compared to the endotracheal tube, tracheostomy has the advantage of? A) Tracheostomy is noninvasive, endotracheal tube is invasive. B) Tracheostomy requires suctioning less frequently than endotracheal tube. C) Tracheostomy can be used for long term management of upper airway problems. D) Tracheostomy is used to bypass both the upper and lower airway paths, whereas endotracheal tube is used to bypass only upper airway path. - Answer-C) Tracheostomy can be used for long term management of upper airway problems. 11. During emergencies, the most commonly used method of artificial airways is? A) Nasal endotracheal tube. B) Oral endotracheal tube. C) Tracheostomy.

The priority nursing intervention in this situation is? A) Communicating with the patient orally and assuring him that this is a sign of improvement. B) Providing sedation so the patient can rest. C) Assessing the placement of the tube because talking is a sign of tube displacement. D) Removing the tube immediately and calling the physician. - Answer-C) Assessing the placement of the tube because talking is a sign of tube displacement. 13.
