D._QS/QT,_deadspace_-_Correct_answer~_B.
Barometric_pressure,_FiO2,_and_PaO2_are_all_included_in_the_formula_(BP_stands_for_
barometric_pressure)
L/min/m2_is_the_unit_of_measure_for:
A._Systemic_vascular_resistance
B._Cardiac_output_
C._Cardiac_index
D._Stroke_volume_-_Correct_answer~_C.

pH_7.38_PaCO2_42_mmHgPaO2_76_mmHgHCO3-_24_mEq/LBE_0_mEq/L
,Which_of_the_following_supplemental_oxygen_levels_is_most_appropriate?
_A._2_L/min_nasal_cannula
_B._5_L/min_nasal_cannula
_C._non-rebreathing_mask

_the_patient_is_not_a_COPD_patient_and_the_situation_is_not_an_emergency,_then_the

are_either_insufficient_or_too_much.
Left_heart_failure_would_be_manifested_in_which_of_the_following_values?
_A._CVP_and_mPAP
_B._mPAP_and_wedge_pressure
_C._MAP_and_SVR
_D._cardiac_output_and_wedge_pressure_-_Correct_answer~_D._

tance?
_A._reduced_SpO2
_B._accessory_muscle_use
_C._altered_P50
_D._increased_PetCO2_-_Correct_answer~_B.
,Of_the_options_given,_use_of_accessory_muscles_is_most_closely_associated_with_an_in
crease_in_airway_resistance._This_is_especially_true_with_patients_who_have_asthma_or
_other_types_of_upper_airway_inflammation_or_bronchoconstriction.
For_a_patient_receiving_volume-
controlled_mechanical_ventilation,_the_lower_inflection_point_on_a_pressure-
volume_loop_can_best_be_described_as:
_A._amount_of_pressure_required_to_keep_the_alveoli_and_small_airways_open
_B._optimal_PEEP
_C._minimal_PEEP
_D._upper_limit_of_residual_volume_-_Correct_answer~_A._
The_lowest_inflection_point_on_a_pressure-
volume_ventilator_graphic_is_an_indication_of_the_minimum_pressure_needed_to_keep_
alveoli_open.

_A._fluid_overload
_B._ARDS
_C._a_pulmonary_embolism
_D._pneumonia_-_Correct_answer~_C._

_C._Replace_Albuterol_with_Beclamethasone_(Beclovent)
_D._Switch_from_Albuterol_to_ipratropium_bromide_(Atrovent)_-_Correct_answer~_D.
Because_albuterol_is_a_beta-agonist_medication,_patients_who_are_taking_beta-
blockers_should_utilize_other_bronchodilation_medication.
A_hospital_has_an_extremely_low_incidence_of_ventilator-
associated_pneumonia._To_which_of_the_following_reasons_may_this_be_attributed?
_A._periodic_discontinuation_of_sedation
_B._use_of_respiratory_precautions_with_the_population
_C._diversion_of_infectious_patients_to_other_facilities
_D._broad_use_of_prophylactic_antibiotics_-_Correct_answer~_A._
