Question 1

An 80-year-old male patient has been admitted to the acute care facility with the diagnosis of pneumonia.He is receiving oxygen via nasal cannula at 2 L/min.The nurse assesses respirations at 24/min,PaO₂ level 88 mm Hg,and pink skin tone.What action should the nurse implement?

A) Notify thehealth care provider.
B) Increase oxygen to 4 L/min.
C) Record PaO₂ level.
D) Administer nebulizer treatment.

Accepted Answer

The nurse would document PaO₂ level.Normal arterial oxygen levels sometimes decrease with age,but not usually low enough to fall outside the normal range.It may be possible for an 80-year-old person to have an arterial partial pressure oxygen (PaO₂)level (the amount of oxygen found in the arterial circulation)between 80 and 85 mm Hg (normal range is 80 to 100 mm Hg)without experiencing significant alterations in health.

Question 2

The wife of a patient with a cuffed tracheostomy asks why the cuff is inflated intermittently.What is the purpose of the inflated cuff?&#10;A) Prevent regurgitation after meals.&#10;B) Hold the trachea open until it is completely healed.&#10;C) Dilate the tracheal opening for passage of secretions.&#10;D) Prevent aspiration when eating.

Accepted Answer

The purpose of the inflated cuff is to prevent aspiration of food and fluids into the lungs while eating. Intermittent cuff deflation allows for easier breathing and communication when the patient is not eating.

Question 3

A _____________ cannula is a device consisting of small tubes inserted into the nares and is the most common way to administer oxygen.

Accepted Answer

nasal

Question 4

When an older adult patient with chronic emphysema comes to the emergency department in respiratory distress,at what rate should the nurse begin oxygen per nasal cannula?&#10;A) 2 L/min&#10;B) 3 L/min&#10;C) 4 L/min&#10;D) 5 L/min

Accepted Answer

For patients with chronic emphysema, oxygen should be started at a low rate, typically 1-2 L/min, to avoid depressing the respiratory drive. These patients often have a blunted response to high levels of CO2 and rely on low oxygen levels to stimulate breathing.

Question 5

What is the appropriate value for the venturi mask? Oxygen delivery devices with percent of oxygen delivered
$\begin{array} { l l } \text { Delvery device } & \text { Amount of delivered } \mathrm { FiO } _ { 2 } \\\text { Nasal carrula } & 1 - 6 \mathrm { I } / \mathrm { min } = 24 \% - 44 \% \mathrm { O } _ { 2 } \\\text { simple face mask } & 5 - 8 \mathrm { I } / \mathrm { min } = 35 \% - 55 \% \mathrm { O } _ { 2 } \\\text { Venturi mask } & \\\text { Partial rebreather mask } & 6 - 12 \mathrm { I } / \mathrm { min } = 60 \% - 90 \% \mathrm { O } _ { 2 } \\\text { Nerrebreather mask } & 6 - 15 \mathrm { I } / \mathrm { min } = 70 \% - 100 \% \mathrm { O } _ { 2 }\end{array}$

A) 1-6 L/min = 24%-44% O₂
B) 5-8 L/min = 35%-55% O₂
C) 4-10 L/min = 24%-55% O₂
D) 6-12 L/min = 60%-90% O₂
E) 6-15 L/min = 70%-100% O₂

Accepted Answer

The Venturi mask is designed to deliver a precise amount of oxygen. It can typically provide between 24% to 50% or 60% oxygen to the patient, depending on the flow rate and the adapter used. The option stating 4-10 L/min = 24%-55% is closest to this range, allowing for precise control over the FiO2 delivered to the patient.

Question 6

A patient has a new health care provider's order for oxygen administration at 2 L via nasal cannula.Who can initiate implementation of this order? (Select all that apply. )&#10;A) RN&#10;B) UAP&#10;C) Respiratory therapist&#10;D) EMT&#10;E) Nutritional specialist

Accepted Answer

Oxygen therapy may be initiated by a respiratory therapist,a nurse,an emergency medical technician (EMT),or any other licensed health care provider with an appropriate order for the oxygen.In some facilities,there is a respiratory care department,staffed by respiratory therapists who assume the responsibility of administering oxygen and delivering treatments that will improve a patient's ventilation and oxygenation.Adjustment of the oxygen flow rate is not delegated to UA nor nutritional specialist.

Question 7

The nurse instructs a patient receiving home O₂ therapy to drink plenty of fluids to help keep bronchial secretions liquefied.What is the recommended fluid? A) Milk B) Water C) Tea with artificial sweetener D) Coffee

Accepted Answer

Water is the recommended fluid for keeping bronchial secretions liquefied. Milk, tea with artificial sweetener, and coffee can all increase mucus production and should be avoided in patients receiving O₂ therapy.

Question 8

Which of the following is an appropriate nursing measure when performing tracheostomy care?&#10;A) Wear clean gloves.&#10;B) Insert the catheter without suction.&#10;C) Suction for 1 minute before removing the catheter.&#10;D) Place the used catheter in a plastic shield for later use.

Accepted Answer

Insertion of the suction catheter without suction reduces the probability of tissue injury.Sterile gloves should be used for tracheostomy care.Suctioning should be done for a maximum of 10 seconds at a time.A used catheter should be disposed of appropriately.

Question 9

The nurse is caring for a patient with an endotracheal tube.What interventions will the nurse implement? (Select all that apply. )&#10;A) Change or clean all respiratory therapy equipment every 24 hours.&#10;B) Turn and reposition the patient every 2 hours.&#10;C) Provide constant airway humidification.&#10;D) Encourage intake of fruits and vegetables.&#10;E) Elevate the head of the bed.

Accepted Answer

Nursing interventions for the patient with an endotracheal tube include turning and repositioning every 2 hours for maximal ventilation and lung expansion,constant airway humidification and elevation of the head of the bed to assist with ventilation.Equipment should be changed or cleaned at least every 8 hours.Patients with endotracheal tubes are allowed nothing by mouth (NPO).It is necessary to provide parenteral or enteral nourishment.

Question 10

When suctioning a tracheostomy suction may be applied for a maximum of __ seconds at a time never longer.

Accepted Answer

The answer of When suctioning a tracheostomy suction may be...
