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 BVMtechnique is being used?

1 A memberof the resuscitation team is preparing to administermedications 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 answerto 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 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 hyperkalemiais 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 Twaves ` ` ` ` ` ` `
ST-segment changes, T-wave inversion ` ` `
Flat T waves, prominent Uwaves and possibly prolonged QT intervals
` ` ` ` ` ` ` ` `
Narrow-complex ventricular tachycardia ` `
In hyperkalemia the patient's 12-lead ECGrhythm strip will show wide-complexventricular rhythm and tall,
` ` ` ` ` ` ` ` ` ` ` ` ` `
peaked Twaves.

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. Aftercompleting 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 initiatetherapy for this patient no later than by which time?
` ` ` ` ` ` ` ` ` ` ` ` ` ` ` `

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 answerto this question.
` ` ` ` ` `
"We kept the rate of chest compressions to around 100 per minute but adjusted theirdepth to
` ` ` ` ` ` ` ` ` ` ` ` ` ` ` `
1.5 inches while giving 1ventilation every 3seconds."
` ` ` ` ` ` ` `
"We delivered chestcompressionsata rate of 80 to 100 perminute toa depthof at least2
` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` `
inches and gave 1 ventilation every 6seconds."
` ` ` ` ` ` ` `
"We initiated chestcompressionsatarate of 100 to 110 perminute toa depthof 2.4 inches and then
` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` `
gave 1 ventilation every 10 seconds."
` ` ` ` ` `
"We delivered 1ventilation every 6seconds andchest compressions ata rate of 100 to 120
` ` ` ` ` ` ` ` ` ` ` ` ` ` ` `
compressions perminute."

A patient with a suspected stroke arrives at the emergency department at 7:10 p.m. The stroke team ensures
` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` `
that a comprehensive neurologicassessment using the National Institutes of Health Stroke Scale (NIHSS) is
` ` ` ` ` ` ` ` ` ` ` ` ` ` `
completed and that brain imaging is performed by which time?
` ` ` ` ` ` ` ` ` `
7:20 p.m. `
7:30 p.m. `
7:40 p.m. `
7:50 p.m. `
Within 20 minutes of the patient's arrival, a comprehensiveneurologicassessment should be completed and
` ` ` ` ` ` ` ` ` ` ` ` ` `
brain imaging should be performed. That would be 7:30 p.m. for this patient.

` ` ` ` ` ` ` ` ` ` ` ` ` ` `
electrolyte imbalance(s) would most likely be involved?
