Question 1

The nurse is providing care to a patient admitted with a respiratory disorder. Which laboratory finding would be most significant?

Accepted Answer

A blood pH of 7.32 indicates acidosis, which is significant in a patient with a respiratory disorder as it suggests inadequate gas exchange or respiratory function.

Question 2

The nurse is performing in-line suctioning when the patient experiences a decrease in oxygen saturation and bradycardia. Which nursing action is best?

Accepted Answer

Discontinuing suctioning and administering 100% oxygen is the best action in this scenario. The decrease in oxygen saturation and bradycardia indicate that the patient is not tolerating the procedure well and may be experiencing hypoxia. Administering 100% oxygen can help quickly reverse the hypoxia, and discontinuing suctioning reduces further stimulation that could exacerbate the situation.

Question 3

The nurse is providing education to a patient regarding the use of an incentive spirometer. Which patient statement indicates the need for further education?

Accepted Answer

The correct frequency for using an incentive spirometer is typically 10 times per hour while awake, not 20 times.

Question 4

The nurse is providing care to a patient diagnosed with chronic obstructive pulmonary disease (COPD) who is prescribed 24% oxygen at 2 L/min. Which is the best method for the nurse to use to administer oxygen to this patient?

Accepted Answer

A nasal cannula is the best method for administering low-flow oxygen, such as 24% at 2 L/min, to a patient with COPD, as it allows for precise oxygen delivery while maintaining comfort and the ability to eat and speak.

Question 5

The nurse is providing care to a patient who is mechanically ventilated. Which nursing action is most effective in decreasing the risk for aspiration?

Accepted Answer

Elevating the head of the bed between 30 to 45 degrees is the most effective action in decreasing the risk for aspiration in mechanically ventilated patients. This position helps prevent gastric contents from entering the lungs.

Question 6

The nurse provides education to a patient who is going to be discharged from the hospital with oxygen. Which patient statement indicates the need for further education?

Accepted Answer

Storing oxygen tanks in a closet or any confined space is dangerous due to the risk of oxygen enrichment and potential fire hazards. Oxygen tanks should be stored in a well-ventilated area, standing upright, and secured to prevent tipping.

Question 7

The nurse is providing care to a patient who is recovering from facial trauma who requires high-flow oxygen therapy. Which method of oxygen delivery does the nurse recognize as best for this patient?

Accepted Answer

A face tent is the best option for a patient recovering from facial trauma who requires high-flow oxygen therapy, as it allows for the delivery of high concentrations of oxygen without causing further discomfort or pressure on the facial injuries, unlike options that require direct contact with the nose or mouth.

Question 8

The nurse places the patient in which position before performing in-line suctioning?

Accepted Answer

Semi-Fowler's position is recommended for in-line suctioning because it allows for better access and minimizes the risk of aspiration. This position, where the patient is partially sitting up (at about 30 to 45 degrees), facilitates easier breathing and is safer for suctioning procedures.

Question 9

The nurse assists the healthcare provider with a patient intubation. What is the priority action by the nurse?

Accepted Answer

The answer of The nurse assists the healthcare provider with...

Question 10

During auscultation of breath sounds, the nurse hears wheezing and correlates to which sound?

Accepted Answer

Wheezing is characterized by high-pitched squeaking sounds caused by the narrowing of the airways, often heard in conditions like asthma or chronic obstructive pulmonary disease (COPD).

Question 11

The nurse suctions a patient's tracheostomy tube. During the procedure, the patient's heart rate drops to the low 50s and oxygen saturation falls to 85%. Which is the priority action by the nurse?

Accepted Answer

Stopping the suctioning procedure and administering oxygen is the priority action to address the patient's immediate needs for adequate oxygenation and to prevent further deterioration.

Question 12

The nurse is providing education to a patient who is prescribed oxygen in the home environment. Which statement made by the patient indicates the need for further education?

Accepted Answer

Storing oxygen on its side is incorrect; oxygen tanks should be stored upright to prevent them from falling and potentially causing damage or injury. This indicates a misunderstanding and the need for further education.

Question 13

The nurse is providing care to a patient who has a tracheostomy. The nurse plans to monitor this patient for the loss of which protective mechanism during the respiratory assessment process?

Accepted Answer

A tracheostomy bypasses the upper airway, which normally filters and humidifies inspired air.

Question 14

Which nursing action best determines the accuracy of the detected waveform when monitoring a patient's oxygen saturation via oximetry?

Accepted Answer

Comparing the heart rate with the displayed pulse ensures that the oximeter is accurately detecting the patient's pulse, confirming the waveform's accuracy.

Question 15

The nurse is providing care to a patient who is diagnosed with chronic obstructive pulmonary disease (COPD). The patient's pulse oximetry is 93% on room air with a current respiratory rate of 35 breaths per minute. The most recent chest x-ray indicates a flattened diaphragm with infiltrates. The patient is currently febrile with an increased number of white blood cells (WBCs) noted on the latest complete blood count (CBC). Which order does the nurse question for this patient based on the current data?

Accepted Answer

For a patient with COPD, oxygen therapy needs to be carefully managed because their drive to breathe is often regulated by low oxygen levels rather than high carbon dioxide levels, as in healthy individuals. Administering oxygen at 3 to 4 L/min may elevate the patient's oxygen saturation above their normal range, potentially suppressing their drive to breathe and leading to carbon dioxide retention and respiratory failure. The other interventions (raising the head of the bed, adding humidification, and chest physiotherapy) are appropriate for managing symptoms and preventing complications in COPD.

Question 16

When conducting a respiratory assessment, the nurse notes a low-pitched sound that is continuous throughout inspiration. Which does this lung sound indicate to the nurse?

Accepted Answer

A low-pitched, continuous sound throughout inspiration is typically indicative of rhonchi, which suggests blocked or obstructed large airway passages.

Question 17

When conducting in-line suctioning, the nurse recognizes which of the following is the maximum amount of time for each suctioning event?

Accepted Answer

The maximum amount of time recommended for each suctioning event when conducting in-line suctioning is 10 seconds to minimize the risk of hypoxia and other potential complications.

Question 18

Which sound heard during auscultation of the breath sounds does the nurse correlate to rhonchi?

Accepted Answer

Rhonchi are described as low-pitched, snoring sounds heard during auscultation of the lungs, often associated with obstruction or secretions in the larger airways.

Question 19

When conducting in-line suctioning on a patient, which amount of time does the nurse allow as a rest period between suction procedures?

Accepted Answer

The answer of When conducting in-line suctioning on a patient,...

Question 20

The nurse is providing care to a patient diagnosed with chronic obstructive pulmonary disease (COPD) who requires supplemental oxygen. Which is the correct flow rate range by nasal cannula (NC) when providing care for this patient?

Accepted Answer

For patients with COPD requiring supplemental oxygen, a low flow rate of 1 to 2 L/min is recommended to avoid suppressing their drive to breathe, which is often triggered by low oxygen levels rather than high carbon dioxide levels as in individuals without COPD.
