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?
Narrow-complex ventricular tachycardia
Flat T waves, prominent U waves and possibly prolonged QT intervals
ST-segment changes, T-wave inversion
Wide-complex ventricular rhythm and tall, peaked T waves

Wide-complex ventricular rhythm and tall, peaked T waves
In hyperkalemia, the patient's 12-lead ECG will show a wide-complex
ventricular rhythm and tall, peaked T waves.
,The stroke team is assessing a patient with a suspected stroke. The patient is alert and
able to carry on a conversation, although the patient has difficulty getting the words
out. Testing confirms that the patient has had an ischemic stroke. Based on the
patient's medical history, a history of which arrhythmia would alert the team to the
patient's increased risk for stroke?
Atrial fibrillation
Atrial tachycardia
Ventricular fibrillation
Bradycardia
Give this one a try later!
Atrial fibrillation
Between 15 and 20 percent of embolic strokes are caused by atrial
fibrillation.
A 35-year-old female patient's ECG is consistent with STEMI. The ECG reveals a new
ST-segment elevation at the J point in leads V2 and V3 of at least which size?
0.10 mV
0.15 mV
0.2 mV
0.25 mV
Give this one a try later!
, 0.15 mV
New ST-segment elevation at the J point in leads V2 and V3 of at least 0.15
mV (1.5 mm) in women 40 years or younger is considered diagnostic of
STEMI.
The following capnogram is from a patient experiencing respiratory distress. At which
point in the waveform would the patient's ETCO2 level be measured?
B
C
D
E
Give this one a try later!
D
The ETCO2 value is measured at the end of exhalation (point D), which
represents the peak level.
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?
Hypertension
Esophageal injury
Pneumothorax
Rib fracture
Give this one a try later!
, 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.
Which areas are evaluated using the National Institutes of Health Stroke Scale
(NIHSS)?
Facial palsy
Hearing
Language deficits
Visual function
Level of consciousness
Give this one a try later!
Facial palsy
Language deficits
Visual function
Level of consciousness
The National Institutes of Health Stroke Scale (NIHSS) evaluates level of
consciousness, best gaze, visual fields, facial palsy, motor function (arm and
leg), limb ataxia, sensation, language deficits and extinction and inattention.
A patient is receiving ventilation support via bag-valve-mask (BVM) resuscitator.
Capnography is established and a blood gas is obtained to evaluate the adequacy of
the ventilations. Which arterial carbon dioxide (PaCO2) value signifies adequate
ventilations?
10 to 15 mmHg
20 to 25 mmHg
