Oxygen via nonrebreathing mask and a focused secondary assessment

Which of the following statements regarding pulse oximetry is correct?

Pulse oximetry measures the percentage of hemoglobin that is saturated with oxygen, but does not measure the actual hemoglobin content of the blood.

Which of the following statements regarding the hypoxic drive is correct?

The hypoxic drive stimulates a person to breathe on the basis of low oxygen levels.

adjust the flow rate accordingly until you see symptom improvement, but be prepared to assist his or her ventilations.

In what area of the lungs does respiration occur?

alveoli

A 62-year-old man with a history of congestive heart failure presents with severe respiratory distress and with an oxygen saturation of 82%. When you auscultate his lungs, you hear widespread rales. He is conscious and alert, is able to follow simple commands, and can only speak in two- to three-word sentences at a time. You should:

apply a CPAP device, monitor his blood pressure, and observe him for signs of improvement or deterioration.

chronic stretching of the alveolar walls.

Your patient has a history of congestive heart failure and is complaining of shortness of breath. What type of breath sounds would you anticipate hearing in this patient?

During your assessment, you hear wheezing over all the lung fields. His blood pressure is 90/50 mm Hg and his heart rate is 110 beats/min. In addition to giving him high-flow oxygen, the MOST important treatment for this patient is

epinephrine

All of the following are signs of inadequate breathing except

equal breath sounds

A pleural effusion is MOST accurately defined as:

fluid accumulation outside the lung.

Asthma is caused by a response of the:

immune system

You are dispatched to an apartment complex where a 21-year-old female has apparently overdosed on several narcotic medications. She is semiconscious and has slow, shallow respirations. You should:

insert a nasopharyngeal airway and begin assisted ventilation.

The two processes that occur during respiration are:

inspiration and expiration.

You are assisting an asthma patient with his prescribed metered-dose inhaler. After the patient takes a deep breath and depresses the inhaler, you should:

instruct him to hold his breath for as long as he comfortably can.

you respond to a homeless shelter for a 48- year- old male who is unconscious in respiratory distress. on arrival, the shelter tells you that the man had been complaining of fever, trouble breathing, sweating at night, and a persistent cough for the past week. he also noticed that the man has lost a significant amount of weight in the past month. which of the following pieces of personal protective equipment is the most important to don before making contact with this patient?

n-95 respirator

In order for efficient pulmonary gas exchange to occur:
