1.A patient experiences cardiac arrest, and the resuscitation
team initiates 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
,Hypertension: Pneumothorax
2.1 A member of the resuscitation team is preparing to
administer medica- tions 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 mL: When administering medications during a cardiac arrest,
all medica- tions administrated through the IV or intraosseous infusion
route should be followed by a 10- to 20-mL fluid bolus.
,3.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 tachycardia: 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.
4.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?
