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?
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?
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?
An SaO2 level of less than 90% (PaO2 of less than 50 mmHg)
accompanied by ETCO2 values greater than 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?
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?
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?
A systematic approach to assessment is necessary. Th [Show Less]
