NRSG 2500 Unit 6 Questions with
Correct Answers for Specific Exam
Mail
PaO2 in ARF
Ans: Less than 50
PaCO2 in ARF
Ans: Greater than 50
S/S of ARF
Ans: Mismatch V/Q, restlessness, fatigue, headache, air
hunger, tachycardia, increased BP
Example of Absolute Shunting
Ans: ARDS
Example of High Ratio
Ans: Cardiogenic Shock
Pretest - Stuvia US
,2
Acute Respiratory Distress Syndrome (ARDS) definition
Ans: Syndrome characterized by sudden, progressive
pulmonary edema, increasing bilateral infiltrates on CXR,
hypoxemia refractory to oxygen therapy, decreased lung
compliance
S/S of ARDS
Ans: Rapid onset of severe dyspnea, restlessness,
tachycardia, hypoxemia that does not respond to
supplemental oxygen, BNP less than 100
Management of ARDS
Ans: Intubate and Ventilate!
PEEP
Positioning- frequent position changes (prone is best)
Nutritional support- enteral or TPN
Oral care
Skin care
ROM
Flail Chest
Pretest - Stuvia US
, 3
Ans: Chest wall moves paradoxically with respiration as a
result of multiple fractures of the ribs
Venturi Mask
Ans: The most accurate way to deliver oxygen and is
primarily used for patients with COPD. It provides
appropriate levels, thus avoiding the risk of suppressing
the hypoxic drive.
Nonrebreathing Mask
Ans: A face mask and reservoir bag device that delivers
high concentrations of oxygen. The patient's exhaled air
escapes through a valve and is not rebreathed.
Partial Rebreathing Mask
Ans: A mask similar to the nonrebreathing mask but
without a one-way valve between the mask and the
reservoir; room air is not drawn in with inspiration; residual
expired air is mixed in the mask and rebreathed.
