Exam 34: Determinants and Assessment of Oxygenation

A nurse is monitoring trends of a patient's SvO2 as a measure of oxygen delivery to tissues.The nurse would be concerned about the accuracy of this trending if which patient condition develops? Note: Credit will be given only if all correct choices and no incorrect choices are selected. Select all that apply.

The nurse is caring for a patient diagnosed with uncontrolled asthma.The nurse implements interventions to help control the effects of asthma on which element of the patient's pulmonary gas exchange?

A patient is diagnosed with lactic acidosis.The nurse plans to provide care to a patient whose energy is being produced through which process?

A patient's PaO₂ level is 56 mm Hg.The nurse would plan care to prevent development of which condition?

A patient has a hemoglobin level of 8.6 mg/dL.The nurse is concerned that which oxygenation component will be affected in this patient?

A patient is going to be assessed for oxygen consumption level.Which parameter will the nurse identify for this assessment?

A patient tells the nurse that he feels more energetic when he wears oxygen.What would the nurse consider prior to responding to this statement?

The nurse assessing a patient with multiple injuries is concerned about the patient's ability to maintain adequate oxygenation.Which explanation would the nurse provide for this increased concern?

A patient's mixed venous oxygen saturation level is 56%.What evaluation would the nurse make of this reading?

A patient with chronic obstructive pulmonary disease (COPD)says,"I have to rest a lot.It just wears me out trying to breathe." The nurse interprets this statement to mean the patient has difficulty with which respiratory process?

The nurse is planning essential activities for a critically ill patient.In order to provide the least impact on oxygen consumption,the nurse would be certain the patient rests before and after which activity?

The nurse is caring for a patient with impaired diffusion of oxygen secondary to pneumonia.Assessment findings related to this impairment are similar to those the nurse would see in patients with which other disease states?

A patient is diagnosed with iron deficiency anemia.The nurse plans interventions for a patient with which most likely complication?

A patient injured in an explosion has a flail chest and crushing injuries to her left arm and leg.She is unconscious and is losing blood rapidly.Laboratory testing reveals impaired oxygenation.Nursing interventions should be implemented to improve which components of oxygenation disrupted by this injury? Note: Credit will be given only if all correct choices and no incorrect choices are selected. Select all that apply.

A patient is being started on oxygen therapy for an oxygen saturation level of 84% on room air.The nurse expects that this therapy will be effective if oxygen enters the blood through which physiological process?

A nurse reviewing arterial blood gas results identifies the oxygen saturation level as low.The nurse interprets this information to reflect changes in which process?
