ATI Advanced Med Surg Exam 3 Questions
Extract:
Question 1 of 5
Which assessment finding by the nurse caring for a patient receiving mechanical ventilation indicates the need for suctioning?
Correct Answer: D
Rationale: A drop in oxygen saturation to 93% suggests airway obstruction or secretions, indicating the need for suctioning.
Question 2 of 5
A 78-kg patient in septic shock has a pulse rate of 120 beats/min with low central venous pressure and pulmonary artery wedge pressure. After initial fluid volume resuscitation, the patient's urine output has been 30 mL/hr for the past 3 hours. Which order by the health care provider should the nurse question?
Correct Answer: B
Rationale: Furosemide is inappropriate in septic shock with low urine output, as it may worsen hypovolemia and organ perfusion.
Question 3 of 5
A nurse is assessing a client who has atrial fibrillation. Which of the following pulse characteristics should the nurse expect?
Correct Answer: A
Rationale: Atrial fibrillation causes an irregularly irregular pulse due to chaotic atrial activity and inconsistent ventricular responses.
Question 4 of 5
A patient who has been involved in a motor vehicle crash arrives in the emergency department (ED) with cool, clammy skin; tachycardia; and hypotension. Which intervention prescribed by the health care provider should the nurse implement first?
Correct Answer: A
Rationale: Ensuring adequate oxygenation with 100% oxygen via a non-rebreather mask is the priority to address hypoxia and stabilize the patient in shock.
Question 5 of 5
A nurse is caring for a client with a ventricular pacemaker who is on ECG monitoring. The nurse understands that the pacemaker is functioning properly when which of the following appears on the monitor strip?
Correct Answer: A
Rationale: Pacemaker spikes before each QRS complex indicate proper ventricular pacing, stimulating ventricular depolarization.
