A patient with suspected acute coronary syndromes (ACS) is placed on a cardiac monitor. The
patient is complaining of dyspnea and is given supplemental oxygen. The provider determines
that the oxygen is effective based on which SaO2 level? - (answer)When a patient presents with
potential ACS, the patient should have oxygen administered to maintain an SaO2 of at least 94%.
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? -
(answer)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.
Assessment of a patient reveals an ETCO2 level of 55 mmHg and an arterial oxygen saturation
(SaO2) level of 88%. The provider would interpret these findings as indicative of which

condition? - (answer)An SaO2 level of less than 90% (PaO2 of less than 50 mmHg)
accompanied by ETCO2 values greater than 的”中文文章
50 mmHg is indicative of respiratory failure.
A healthcare provider initiates ventilations to ensure adequate breathing and oxygenation. While
ventilations are being performed, capnography is established to evaluate the adequacy of the
ventilations. The healthcare provider determines that ventilations are adequate based on which
end-tidal carbon dioxide (ETCO2) value? - (answer)End-tidal carbon dioxide values in the range
of 35 to 45 mmHg confirm adequacy of ventilation.
A patient comes to the emergency department complaining of palpitations and "some shortness
of breath." Cardiac monitoring is initiated and reveals the following ECG rhythm strip. The
provider interprets this strip as indicating which arrhythmia? - (answer)In atrial flutter, atrial
contraction occurs at such a rapid rate that discrete P waves separated by a flat baseline cannot be
seen on the strip. Instead, the baseline continually rises and falls, producing the "flutter" waves.
In leads II and III, the flutter waves may be quite prominent, creating a "sawtooth" pattern.
Because of the volume of atrial impulses, the AV node allows only some of the impulses to pass
through to the ventricles. In atrial flutter, a 2:1 ratio is the most common (i.e., for every two
, flutter waves, only one impulse passes through the AV node to generate a QRS complex). Ratios
of 3:1 and 4:1 are also frequently seen.
A person suddenly collapses while sitting in the sunroom of a healthcare facility. A healthcare
provider observes the event and hurries over to assess the situation. The healthcare provider
performs which assessment first? - (answer)A systematic approach to assessment is necessary.
The healthcare provider should first perform a rapid assessment. A rapid assessment is a quick
visual survey to ensure safety, to form an initial impression about the patient's condition, and to
check for responsiveness, breathing and a pulse if the patient appears to be unresponsive. This
would be followed by a primary assessment and then a secondary assessment.
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? - (answer)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.
An ECG strip of a patient in the emergency department reveals the following rhythm. Which
feature would the healthcare provider interpret as indicating atrial fibrillation? - (answer)The two

key features of atrial fibrillation on ECG are the absence of discrete P waves and the presence of
irregularly irregular QRS complexes. 的”中文文章
A patient presents to the emergency department with mild to moderate recurrent chest pain,
without any nausea or vomiting. A 12-lead ECG is obtained and shows ST-segment depression
with transient T-wave elevation indicative of NSTE-ACS. Cardiac enzyme levels are obtained
and are not elevated. These findings suggest which condition? - (answer)A patient who presents
with ECG findings consistent with NSTE-ACS and does not have elevated cardiac serum
markers is to be considered as having unstable angina.
A healthcare provider is establishing cardiac monitoring using a five-electrode system. The
healthcare provider demonstrates proper use of the system by placing the green electrode in
which location? - (answer)In a five-electrode cardiac monitoring system, the green electrode
should be placed on the lower right abdomen.
