A patient experiences cardiac arrest, and the resuscitation team initiates
... [Show More] ventilations using a bag-valve-mask (BVM) resuscitator. The development of which condition during the provision of care would lead the team to suspect that improper BVM technique is being used?
Select the correct answer to this question.
Rib fracture
Esophageal injury
Pneumothorax
HypertensionANSWER Pneumothorax
Complications can occur with the use of a BVM resuscitator due to improper technique. Delivering excessive volume or ventilating too fast creates excessive pressure that can damage the airways, lungs and other organs. Excessive volume can lead to tension pneumothorax.
1 A member of the resuscitation team is preparing to administer medications intravenously to a patient in cardiac arrest. The team member follows each medication administration with a bolus of fluid. How much would the team member give?
Select the correct answer to this question.
5 to 10 mL
10 to 20 mL
20 to 30 mL
30 to 40 mLANSWER When administering medications during a cardiac arrest, all medications administrated through the IV or intraosseous infusion route should be followed by a 10- to 20-mL fluid bolus.
The resuscitation team suspects that hyperkalemia is the cause of cardiac arrest in a patient brought to the emergency department. Which finding on a 12-lead ECG would confirm this suspicion?
Wide-complex ventricular rhythm and tall, peaked T waves
ST-segment changes, T-wave inversion
Flat T waves, prominent U waves and possibly prolonged QT intervals
Narrow-complex ventricular tachycardiaANSWER Wide-complex ventricular rhythm and tall, peaked T waves
In hyperkalemia the patient's 12-lead ECG rhythm strip will show wide-complex ventricular rhythm and tall, peaked T waves.
A patient with an ischemic stroke arrives at the emergency department at 2 a.m. The patient's symptoms started about 12:30 a.m. After completing the necessary assessments, the healthcare team diagnoses an ischemic stroke, and the patient is determined to be a candidate for fibrinolytic therapy. To achieve the best outcomes, the team should initiate therapy for this patient no later than by which time?
Select the correct answer to this question.
3:00 a.m.
5:30 a.m.
6:00 a.m.
8:30 a.m.ANSWER 3:00 a.m.
For patients with ischemic stroke who meet the eligibility criteria, fibrinolytic therapy is the first-line treatment. Administration of IV recombinant tissue plasminogen activator within 3 hours of the onset of signs and symptoms is optimal (with a goal "door-to-needle" time of less than 1 hour).
A resuscitation team is debriefing following a recent event. A patient experienced cardiac arrest, and advanced cardiac life support was initiated. The patient required the placement of an advanced airway to maintain airway patency. Which statement indicates that the team performed high-quality CPR?
Select the correct answer to this question.
"We kept the rate of chest compressions to around 100 per minute but adjusted their depth to 1.5 inches while giving 1 ventilation every 3 seconds."
"We delivered chest compressions at a rate of 80 to 100 per minute to a depth of at least 2 inches and g [Show Less]
