1. A client with suspected acute coronary syndromes (ACS) is placed on a cardiac
monitor. Theclient is complaining of dyspnea and is given supplemental oxygen.
The provider determinesthat the oxygen is effective based on which SaO2 level?
CORRECT ANSWER>>
When a client presents with potential ACS, the client should have oxygen administered
tomaintain an SaO2 of at least 94%.
2. A client experiences cardiac arrest, and the resuscitation team initiates ventilation
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? CORRECT 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 damagethe airways, lungs and other organs. Excessive volume can
lead to tension pneumothorax.
3. A healthcare provider initiates ventilations to ensure adequate breathing and
oxygenation. Whileventilations 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?
CORRECT ANSWER>>
4. Assessment of a client 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? CORRECT ANSWER>>
An SaO2 level of less than 90% (PaO2 of less than 50 mmHg) accompanied by ETCO2
valuesgreater than 50 mmHg is indicative of respiratory failure.
, End-tidal carbon dioxide values in the range of 35 to 45 mmHg confirm adequacy of
ventilation.
5. A client comes to the emergency department complaining of palpitations and
"some shortnessof breath." Cardiac monitoring is initiated and reveals the
following ECG rhythm strip. The provider interprets this strip as indicating which
arrhythmia? CORRECT 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 onlysome 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.
6. A 35-year-old female client'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? CORRECT ANSWER>>
New ST-segment elevation at the J point in leads V2 and V3 of at least 0.15 mV (1.5
mm) inwomen 40 years or younger is considered diagnostic of STEMI.
7. An ECG strip of a client in the emergency department reveals the following
rhythm. Whichfeature would the healthcare provider interpret as indicating
atrial fibrillation? CORRECT ANSWER>>
The two key features of atrial fibrillation on ECG are the absence of discrete P waves
and thepresence of irregularly irregular QRS complexes.
