b) systolic, right
c) diastolic, left
d) diastolic, right
Answer D
3.what is an advantage of a systemic approach to patient assessment?
a) reduces the need for secondary assessment
b) standardizes treatment across systems of care
c) reduces the chances of missing important signs and symptoms
,d) permits assessment modification based on patient symptoms
Answer C
4.what is the first step in the systematic approach to patient assessment?
a) primary assessment
b) secondary assessment
c) initial impression
d) BLS assessment
Answer c
5.what is the maximum amount of time you should simultaneously
perform the pulse and breathing checks?
a) 15 seconds
b) 20 seconds
c) 10 seconds
d) 5 seconds
Answer C
6.The BLS Assessment is a systematic approach to BLS for trained
healthcare providers. This approach stresses
a) basic airway management
b) early cpr and defibrillation
c) defibrillation
Answer b
,7.while performing the BLS assessment, you initiate high-quality CPR
and assist ventilation with a bag-mask device
the AED does not recommend a shock
which action in the primary assessment should you perform first?
a) attach a quantitative waveform capnography device
b) perform fluid resuscitation
c) determine if the patient's airway is patent
d) assess the patient's oxygenation status
Answer C
8.the initial assessment reveals a conscious patient
the patient's airway is patent, and an advanced airway is not indicated
which action in the primary assessment should you perform next?
a) check for the presence of a pulse
b) remove clothing to perform a physical examination
c) administer oxygen as needed
d) check for neurologic function
Answer C
9.during CPR, chest compression fraction (CCF) should be at least %
and idealls greater than %
Answer 60, 80
10.among others, which of the following factors has been associated
, with improved survival in patients with cardiac arrest?

Answer C
11.which action is part of the secondary assessment of a conscious patient?
a) formulate a differential diagnosis
