Question 1
Regular
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?
Correct!
Incorrect
The correct answer is: A
Rationale
Oxygen should be administered at 2 L/min via nasal cannula for an older adult with chronic emphysema in respiratory distress. This rate helps avoid respiratory compromise while ensuring adequate oxygenation.
B: 3 L/min This flow rate may lead to excessive oxygen levels, potentially causing carbon dioxide retention in chronic emphysema patients, exacerbating respiratory distress.
C: 4 L/min At this level, the risk of oxygen toxicity increases, which could further impair the patient's respiratory function and lead to complications in chronic lung conditions.
D: 5 L/min Administering oxygen at this flow rate can overwhelm the patient's respiratory drive, possibly resulting in respiratory failure or significant discomfort for individuals with chronic emphysema.

Question 2
Regular
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?
Correct!
Incorrect
The correct answer is: B
Rationale
Water is the recommended fluid.
Staying well-hydrated with water is essential for patients on home O2 therapy as it effectively helps thin and liquefy bronchial secretions, promoting easier breathing and preventing mucus buildup.
A: Milk may thicken secretions, making it harder to clear the airways and could lead to increased respiratory issues in patients requiring oxygen therapy.
C: Tea with artificial sweetener can contribute to dehydration and may not be as effective as plain water in maintaining optimal hydration levels for effective respiratory function.
D: Coffee, being a diuretic, can lead to increased fluid loss, thereby counteracting the benefits of hydration needed for maintaining clear bronchial passages in patients on oxygen therapy.

Question 3
Regular
The wife of a patient with a cuffed tracheostomy asks why the cuff is inflated intermittently. What is the purpose of the inflated cuff?
Correct!
Incorrect
The correct answer is: D
Rationale
The inflated cuff serves to prevent aspiration when eating.
This is crucial for patients with a cuffed tracheostomy, as the cuff acts as a barrier, ensuring that food and liquids do not enter the airway, reducing the risk of aspiration pneumonia and safeguarding respiratory health during meals.
A: Prevent regurgitation after meals. While regurgitation may occur, the cuff's primary function relates to aspiration prevention, not managing digestive issues after eating.
B: Hold the trachea open until it is completely healed. The cuff does not serve to keep the trachea open; its purpose is to protect the airway during swallowing, not structural support.
C: Dilate the tracheal opening for passage of secretions. The cuff's role is not to facilitate secretion passage; it is designed to maintain airway protection while swallowing, not to aid in secretion management.

Question 4
Regular
Which of the following is an appropriate nursing measure when performing tracheostomy care?
Correct!
Incorrect
The correct answer is: B
Rationale
Insert the catheter without suction. This measure allows for the safe placement of the catheter without causing unnecessary trauma or discomfort to the patient, ensuring a more effective suctioning process afterward.
A: Wear clean gloves. While wearing clean gloves is a standard practice for infection control, it does not specifically address the critical technique required during tracheostomy care.
C: Suction for 1 minute before removing the catheter. Suctioning for an extended period can lead to hypoxia and respiratory distress, making this approach counterproductive and potentially harmful to the patient’s well-being.
D: Place the used catheter in a plastic shield for later use. Reusing a catheter poses significant infection risks and does not adhere to best practices for maintaining sterile equipment in tracheostomy care.

Question 5
Regular
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?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Record PaO2 level. Monitoring the patient's PaO2 is essential to assess the effectiveness of the current oxygen therapy and the progression of pneumonia, ensuring timely interventions if necessary.
A: Notify the health care provider. Immediate notification may not be necessary at this moment, as other actions, like monitoring oxygen levels, can provide critical information about the patient's condition.
B: Increase oxygen to 4 L/min. Raising the oxygen flow rate without evaluating the patient's current status risks potential oxygen toxicity and does not address the need for assessment first.
D: Administer nebulizer treatment. Nebulizer treatments are not indicated without clear evidence of bronchospasm or wheezing, making this option inappropriate for the patient's current condition of pneumonia.

Question 6
Regular
What is the appropriate value for the Venturi mask? Oxygen delivery devices with percent of oxygen delivered
Correct!
Incorrect
The correct answer is: C
Rationale
C: 4-10 L/min = 24%-55% O2. This range accurately reflects the Venturi mask's function, which allows for controlled oxygen delivery, providing precise percentages of oxygen suitable for patients with varying needs.
A: 1-6 L/min = 24%-44% O2. This option underestimates the range of oxygen delivered by a Venturi mask, failing to account for the higher oxygen percentages achievable within the specified flow rates.
B: 5-8 L/min = 35%-55% O2. This selection does not encompass the full spectrum of oxygen concentrations available through a Venturi mask, overlooking lower flow rates that still deliver adequate oxygen percentages.
D: 6-12 L/min = 60%-90% O2. This range suggests excessively high oxygen delivery that is beyond the typical capabilities of a Venturi mask, which is meant for more controlled oxygen concentrations.
E: 6-15 L/min = 70%-100% O2. This option proposes unrealistic oxygen delivery levels for a Venturi mask, which is designed for specific concentrations rather than the extremely high percentages indicated here.

Question 9
Calculation(ans only)
A cannula is a device consisting of small tubes inserted into the nares and is the most common way to administer oxygen.
Correct!
Incorrect
The correct answer is: NASAL
Rationale
Nasal. The cannula is specifically designed to deliver oxygen through small tubes that fit into the nostrils, making it an effective and widely used method for supplemental oxygen administration.
B: oral. An oral device would not effectively deliver oxygen directly into the respiratory system compared to a nasal cannula, which is tailored for this specific purpose.
C: tracheal. A tracheal method involves a more invasive approach by inserting a tube directly into the trachea, which is not necessary for standard oxygen delivery.
D: buccal. Buccal delivery pertains to the cheeks or oral cavity, which is not suitable for oxygen administration, thus making it an inappropriate choice for this context.

Question 10
Calculation(ans only)
When suctioning a tracheostomy suction may be applied for a maximum of ____ seconds at a time never longer.
Correct!
Incorrect
The correct answer is: 10
Rationale
10
Suctioning a tracheostomy should not exceed 10 seconds at a time to prevent hypoxia and maintain airway patency. Prolonged suctioning can lead to airway trauma and decreased oxygenation, putting the patient at risk.
A: 5
Suctioning for only 5 seconds may not be sufficient to clear secretions effectively, potentially leaving the airway compromised and not addressing the patient's respiratory needs adequately.
B: 15
Allowing suctioning for 15 seconds increases the risk of hypoxia and can cause additional stress on the patient’s respiratory system, which is not advisable during such procedures.
C: 20
A duration of 20 seconds significantly heightens the chance of airway injury and oxygen deprivation, undermining the safety protocols essential for managing tracheostomy care effectively.
