Q

Which clinical findings wil priompt the nurse to evaluate the patient as a priority?

A. Sore throat and fever (102.2 F) (39 C) taken orally
B. SOB after walking up a flight of stairs
C. Soreness of arm after receiving PPD skin test
D. Speaking in three-word sentences with a saturated peripheral O2 (SpO2) of 90% by pulse oximetry

A

D. Speaking in three-word sentences with a saturated peripheral O2 (SpO2) of 90% by pulse oximetry

This patient is showing signs of respiratory distress and potential hypoxia:

Three-word sentences indicate severe dyspnea (the patient can’t speak full sentences without becoming short of breath).

SpO2 of 90% is below the normal range (typically ≥ 95%) and may signal impaired oxygenation.

This is a priority finding because airway and breathing are the highest priorities in nursing (ABC: Airway, Breathing, Circulation).

Q

A patient with status asthmaticus has the following assessment findings: a respiratory rate of 35 breathes per minute, a HR of 110 bpm high-pitches wheezes in all lung fields, and marked assessory muscles to breathe. The patient is receiving an IV steroid and a continuous nebulized bronchodilator medication. Which assessment reveals a worsening of this patient’s condition?

A. Absense of wheezing
B. Tremors in both hands
C. Heart rate decreased to 90 bpm
D. Decreases respiratory rate to 20 breaths/min.

A

A. Absense of wheezing

Rationale:
In a patient with status asthmaticus (a severe, life-threatening asthma attack), the sudden absence of wheezing can indicate a critical worsening of the condition — not improvement. This usually means:

Airflow is so restricted that not enough air is moving to produce wheezing sounds.

This is a sign of impending respiratory failure and requires immediate intervention.

Why the others are not signs of worsening:
B. Tremors in both hands: Likely a side effect of bronchodilators (e.g., albuterol), not necessarily a sign of clinical deterioration.

C. Heart rate decreased to 90 bpm: A decrease from tachycardia (110 bpm) to normal HR (90 bpm) can be a positive sign — unless it’s accompanied by other signs of collapse.

D. Decreased respiratory rate to 20 breaths/min: If this is without signs of fatigue or hypoxia, it might seem like improvement — but if paired with silent chest or mental status changes, it would be concerning. However, by itself, it’s not as immediately alarming as absence of wheezing

Q

🚨 Red Flags (Signs of Worsening or Impending Respiratory Failure):

A

Silent Chest (Absence of Wheezing)

No air movement means the airway is severely obstructed.

This is an emergency.

Inability to Speak in Full Sentences

Often limited to 1–3 words per breath.

Indicates severe respiratory effort.

Drowsiness, Confusion, or Lethargy

Suggests CO₂ retention and hypoxia — a very late and dangerous sign.

Use of Accessory Muscles/Retractions

Indicates the patient is working very hard to breathe.

Neck, chest, and abdominal muscles may visibly contract.

Respiratory Rate that Suddenly Drops

If RR decreases with other signs of fatigue or reduced LOC, it’s not good — it can mean the patient is tiring out.

O2 Saturation Below 90%

Hypoxemia is dangerous and must be corrected promptly.

⚠️ Other Concerning Signs:
Pulsus paradoxus (drop in systolic BP during inspiration >10 mmHg)

Peak flow <50% of personal best or <100 L/min

Cyanosis (bluish lips or nail beds)

✨ Summary Mnemonic: “TIREDD”
Tachypnea/Tachycardia

Inability to speak

Retractions/accessory muscle use

Exhaustion

Drowsiness/confusion

Decreased or absent breath sounds

Q

Which factor may cause hypoxia in a patient with a tracheostomy? Select all that apply.

A. Frequent Suctioning
B. Use of 14 Fr catheter
C. Limited suctioning time
D. Excessive suction pressure
E. Ineffective oxygenation before suctioning

A

The correct answers are:
A. Frequent suctioning
D. Excessive suction pressure
E. Ineffective oxygenation before suctioning

✅ Rationale:
A. Frequent suctioning
✔️ Correct – Frequent suctioning can cause mucosal trauma, airway irritation, and removal of oxygen from the airway, leading to hypoxia.

B. Use of 14 Fr catheter
❌ Incorrect – The size of the catheter must be appropriate for the tracheostomy tube, and a 14 Fr catheter is often appropriate for adult patients. It’s not inherently a cause of hypoxia unless it’s too large or causes obstruction.

C. Limited suctioning time
❌ Incorrect – Short suction duration (≤10–15 seconds) is actually recommended to prevent hypoxia, not cause it.

D. Excessive suction pressure
✔️ Correct – High suction pressure can remove too much air and damage tissue, leading to hypoxemia.

E. Ineffective oxygenation before suctioning
✔️ Correct – Patients should be preoxygenated before suctioning to reduce the risk of oxygen desaturation during the procedure.

Q

Which of the following is a primary reason to teach pursed-lip breathing to clients with emphysema?

A. To promote oxygen intake
B. To strengthen the diaphram
C. To strengthen the intercoastal muscles
D. To promote carbon dioxide elimination

A

D. To promote carbon dioxide elimination

✅ Rationale:
Pursed-lip breathing is taught to clients with emphysema primarily to:

Slow exhalation

Prevent airway collapse

Improve gas exchange

Promote elimination of trapped carbon dioxide (CO₂)

Why the other options are incorrect:
A. To promote oxygen intake
❌ Pursed-lip breathing mainly aids in exhalation, not oxygen intake. It helps keep airways open longer to allow trapped air (and CO₂) to escape.

B. To strengthen the diaphragm
❌ Diaphragmatic breathing does this more effectively, not pursed-lip breathing.

C. To strengthen the intercostal muscles
❌ Not the purpose of this technique.

Q

Which of the following outcomes would be appropriate for a client with COPD who has been discharged to home? The client:

A. Promises to do pursed lip breathing at home
B. States actions to reduce pain
C. States taht he will use oxygen via nasal cannula at 5 L/minute
D. Agrees to call the physician if dypsnea on exertion increases

A

D. Agrees to call the physician if dyspnea on exertion increases

✔️ This is the most appropriate and measurable outcome because it shows the client understands the importance of monitoring and reporting worsening symptoms, which is crucial in managing COPD at home. Early intervention can prevent hospitalization.

Why the others are not the best outcomes:
A. Promises to do pursed lip breathing at home
❌ A promise is not a measurable or reliable outcome. A better option would be: “Demonstrates or verbalizes understanding of how to perform pursed-lip breathing.”

B. States actions to reduce pain
❌ Pain is not typically a primary concern in COPD. The focus is on airway clearance, oxygenation, and managing dyspnea, not pain control.

C. States that he will use oxygen via nasal cannula at 5 L/minute
❌ This could be unsafe. In COPD patients, especially those with chronic CO₂ retention, high-flow oxygen can suppress their respiratory drive. Oxygen therapy must be prescribed and carefully titrated, often starting at 1–2 L/min.

Q

Which two major categoried are incliuded in asthma medications?
A. Control and reliever
B. Preventative and quick acting
C. Steroids and bronchodilators
D. Bronchodilators and anti-inflammatories

A

A. Control and reliever
Asthma medications are broadly classified into two major categories:

Control medications (also called long-term controllers or preventers)

Taken daily to prevent symptoms and attacks

Examples: Inhaled corticosteroids, long-acting beta-agonists (LABAs), leukotriene modifiers

Reliever medications (also called quick-relief or rescue medications)

Used to relieve acute symptoms

Examples: Short-acting beta-agonists (SABAs) like albuterol

Why the other choices are incorrect or less accurate:
B. Preventative and quick acting
❌ Descriptive but not the formal classification used in asthma guidelines.

C. Steroids and bronchodilators
❌ These are types of drugs, not categories of use.

D. Bronchodilators and anti-inflammatories
❌ Again, these are mechanisms of action, not the major clinical categories for asthma management.

Q

Which symptoms is specific for asthma compared with other chronic lung disorders?
A. The patiet is coughing
B. The patient has dypsnea
C. It affects only young people
D. The patient is symptom-free between exacerbations

A

The correct answer is:
D. The patient is symptom-free between exacerbations

✅ Rationale:
Asthma is characterized by reversible airway obstruction, meaning symptoms like wheezing, coughing, and shortness of breath come and go. A hallmark feature of asthma is that the patient often feels completely normal between exacerbations.

Why the others are incorrect:
A. The patient is coughing
❌ Coughing occurs in many lung disorders like COPD, bronchitis, pneumonia, etc. It’s not specific to asthma.

B. The patient has dyspnea
❌ Shortness of breath is also common in many chronic lung diseases, including COPD, interstitial lung disease, and heart failure.

C. It affects only young people
❌ Asthma can occur at any age — while it’s common in children, adults and older adults can develop or have persistent asthma.

Q

When providing suctioning through an endotracheal or tracheostomy tube, which finding would alert the nurse to stop suctioning?

A. The patient’s heart rate increases from 72 to 78 bpm
B. The patient’s coughs uncontrollably during suctioning
C. Oxygen saturation by pulse oximetry is less than 90%
D. Secretions are thich and occulding the suction catheter

A

✅ Rationale:
An SpO₂ below 90% indicates hypoxemia, which is a dangerous complication during suctioning. If this occurs, the nurse should immediately stop suctioning, reoxygenate the patient, and reassess. Preventing hypoxia is a top priority during airway management.

Why the other options are incorrect:
A. Heart rate increases from 72 to 78 bpm
❌ A small HR increase is expected and not concerning during suctioning.

B. The patient coughs uncontrollably during suctioning
❌ Coughing is a normal reflex and helps clear secretions; it’s not a reason to stop unless it’s causing distress or worsening oxygenation.

D. Secretions are thick and occluding the suction catheter
❌ While this indicates a need for possible saline instillation or changing the catheter, it’s not a reason to immediately stop suctioning unless the patient is in distress.

Q

Which interventions would the nurse use to prevent hypoxia during suctioning in the patient with a tracheostomy? Select all that apply.

A. Monitoring the heart rate
B. Monitoring the temperature
C. Monitoring the Respiratory Rate
D. Hyperoxigenating the pateint with 100% oxygen
E. Having the patient take a deep breathes before suctioning

A

✅ Rationale for the Correct Answers:
A. Monitoring the heart rate
✔️ Monitoring the heart rate can provide early indicators of hypoxia or distress, as an increased heart rate may occur when oxygen levels are low.

D. Hyperoxigenating the patient with 100% oxygen
✔️ Pre-oxygenating with 100% oxygen before suctioning helps ensure that the patient has adequate oxygen reserves to prevent desaturation during the procedure.

E. Having the patient take deep breaths before suctioning
✔️ Encouraging the patient to take deep breaths before suctioning can increase oxygen levels and prevent desaturation during the suctioning process.

Why B. Monitoring the temperature and C. Monitoring the respiratory rate are not as relevant:
B. Monitoring the temperature
❌ While monitoring temperature is important for infection control, it is not a direct intervention for preventing hypoxia during suctioning.

C. Monitoring the respiratory rate
❌ Although monitoring respiratory rate is important in assessing the patient’s overall condition, it is not as directly related to preventing hypoxia during suctioning as the other interventions.

Which recommendation will the nurse give to a patient with asthma who reports being afraid to begin an aerobi exercise program because exercise sometiems triggers asthma symptoms. A. Participating in a stretching and light calisthenics program instead B. Avoiding aerobic exercise because it will make symptoms worse C. Using oral corticosteroids to prevent asthma symptoms D. Pre-medicating with a short-acting beta-adrenergic (SABA) medication before exercise
The correct answer is: D. Pre-medicating with a short-acting beta-adrenergic (SABA) medication before exercise ✅ Rationale: For a patient with asthma, exercise can sometimes trigger symptoms, but exercise-induced bronchoconstriction (EIB) can often be managed effectively by pre-medicating with a short-acting beta-adrenergic (SABA) inhaler (e.g., albuterol). This helps open the airways before exercise and reduces the risk of symptoms like wheezing or shortness of breath during physical activity. Why the other options are less appropriate: A. Participating in a stretching and light calisthenics program instead ❌ Stretching and light exercise might be helpful for general flexibility, but aerobic exercise is still an important part of a healthy lifestyle for patients with asthma. Avoiding exercise altogether is not usually recommended. B. Avoiding aerobic exercise because it will make symptoms worse ❌ Complete avoidance of aerobic exercise is not necessary for asthma management. Most people with asthma can safely engage in exercise with the right precautions, like pre-medicating with a SABA inhaler. C. Using oral corticosteroids to prevent asthma symptoms ❌ Oral corticosteroids are usually reserved for severe asthma exacerbations and are not appropriate for routine prevention of exercise-induced symptoms. Inhaled corticosteroids are used for long-term control but are not typically used just for exercise.
26
Which disease of the lungs may occur as a result of exposure to occupational irritants? Select all that apply A. Asthma B. Lung Cancer C. Cystic Fibrosis D. Pulmonary Fibrosis D. COPD
The correct answers are: A. Asthma B. Lung Cancer D. Pulmonary Fibrosis E. COPD ✅ Rationale: Occupational exposure to irritants such as dust, fumes, chemicals, and other hazardous substances can lead to several lung diseases: A. Asthma ✔️ Occupational asthma is a well-known condition where workplace irritants trigger asthma symptoms or exacerbate existing asthma. B. Lung Cancer ✔️ Long-term exposure to carcinogens such as asbestos, radon, and chemical fumes in the workplace increases the risk of developing lung cancer. D. Pulmonary Fibrosis ✔️ Occupational pulmonary fibrosis (e.g., silicosis, asbestosis) occurs from inhaling fine particles in industries like mining, construction, and manufacturing. E. COPD ✔️ Chronic exposure to irritants such as cigarette smoke, dust, and chemical fumes can lead to the development of chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema. Why C. Cystic Fibrosis is incorrect: Cystic fibrosis is a genetic disorder, not caused by environmental exposure. It is a hereditary condition that affects the lungs and digestive system due to mutations in the CFTR gene.
27
Which prescribed medication would the nurse adminster first to a patient with asthma who has pneumonia, is reporting increased SOB, and has inspiratory and ecpiratory wheezes? A. Albuterol 2 inhalations B. Salmeterol 2 inhalations C. Ipratropium 2 inhalations D. Flucasone 2 inhalations
✅ Rationale: For a patient with asthma who has increased shortness of breath (SOB) and wheezing (both inspiratory and expiratory), the first medication to administer is a short-acting beta-agonist (SABA) like albuterol. Albuterol works quickly to relax the smooth muscles of the airways, allowing the bronchioles to dilate and improving airflow. This is crucial in the acute setting of asthma exacerbation, especially when wheezing and difficulty breathing are present. Why the other options are less appropriate: B. Salmeterol 2 inhalations ❌ Salmeterol is a long-acting beta-agonist (LABA) used for maintenance therapy in asthma but is not effective in treating acute exacerbations. LABAs should never be used alone for immediate relief. C. Ipratropium 2 inhalations ❌ Ipratropium is an anticholinergic bronchodilator, and while it can help during an asthma attack, albuterol is generally preferred as the first-line treatment for rapid relief. Ipratropium may be used in combination with albuterol for severe cases. D. Fluticasone 2 inhalations ❌ Fluticasone is an inhaled corticosteroid used for long-term control and prevention of asthma symptoms, but it does not provide immediate relief during an asthma attack. It is not appropriate for acute management of symptoms.
28
The nurse receives a change of shift report on the following patients with COPD. Which patient should the nurse assess first? A. A patient with loud exipratory wheezes B. A patient with a respiratory rate of 38/minutes C. A patient who has a cough productive of thick, green mucus D. A pateint with jugular venous distention and peripheral edema
B. A patient with a respiratory rate of 38/minutes ✅ Rationale: A respiratory rate of 38 breaths per minute is significantly elevated and indicates the patient is likely experiencing acute respiratory distress or hypoxia, both of which are life-threatening conditions in a patient with COPD. The nurse should assess this patient immediately to evaluate for signs of respiratory failure, hypoxia, or exacerbation of COPD, which may require interventions like supplemental oxygen, bronchodilators, or mechanical ventilation. Why the other options are less urgent: A. A patient with loud expiratory wheezes ❌ Expiratory wheezes are common in COPD and usually indicate airway obstruction or bronchospasm. Although this is important to assess, it is less urgent than severe respiratory distress (like a very high respiratory rate). C. A patient who has a cough productive of thick, green mucus ❌ Thick, green mucus suggests a potential respiratory infection, but it does not indicate an immediate life-threatening condition. This patient should still be assessed, but it is not as urgent as a patient with severe respiratory distress. D. A patient with jugular venous distention and peripheral edema ❌ Jugular venous distention (JVD) and peripheral edema suggest right-sided heart failure (cor pulmonale), which can be a complication of COPD. However, respiratory rate of 38/min suggests more immediate concern for respiratory failure or acute exacerbation.
29
A nurse is caring for a patient who is orally intubated and being mechanically ventillated. Which factor regarding an artificial airway increases the patient's risk for developing ventilator-associated pneumonia? Sata A. Bypassing the protective airway mechanisms B. Altering and decreasing the body's immune responses C. Preventing adequate gas exchange at the cellular level D. Causing a hyperactive reaction of mucocilliary clearance E. Allowing aspiration of secretions from the oropharynx
The correct answers are: A. Bypassing the protective airway mechanisms E. Allowing aspiration of secretions from the oropharynx ✅ Rationale: Patients with an artificial airway such as an oral endotracheal tube are at high risk for developing ventilator-associated pneumonia (VAP) due to the following key factors: A. Bypassing the protective airway mechanisms ✔️ Correct – The natural defenses like the epiglottis, gag reflex, and mucociliary clearance are bypassed with intubation, allowing pathogens easier access to the lower respiratory tract. E. Allowing aspiration of secretions from the oropharynx ✔️ Correct – Secretions can pool above the cuff of the endotracheal tube and leak into the lungs, carrying bacteria from the mouth and throat and increasing VAP risk. ❌ Incorrect choices explained: B. Altering and decreasing the body's immune responses Not specific to artificial airways. Immune suppression may increase infection risk, but it is not a direct result of intubation. C. Preventing adequate gas exchange at the cellular level This is a consequence of poor ventilation, not a mechanism that contributes to VAP specifically. D. Causing a hyperactive reaction of mucociliary clearance Actually, mucociliary clearance is reduced or bypassed, not hyperactive, due to the tube and dryness of gases.
30
Which assessment finding would the nurse anticipate for the patient suspected of having pneumonia? Select all that apply. A. Myalgia B. Dyspnea C. Bradypnea D. Bradycardia E. Hemoptysis
The correct answers are: A. Myalgia B. Dyspnea E. Hemoptysis ✅ Rationale: In pneumonia, inflammation and infection of the lung tissue lead to a range of systemic and respiratory symptoms. Here's what to expect: A. Myalgia ✔️ Yes – Body aches (myalgia) are common due to the systemic infection response. B. Dyspnea ✔️ Yes – Shortness of breath is a classic sign due to impaired gas exchange from alveolar inflammation and fluid. E. Hemoptysis ✔️ Yes – Coughing up blood-tinged sputum may occur from irritation and damage to lung tissue or blood vessels. ❌ Incorrect choices: C. Bradypnea ✘ No – Patients with pneumonia typically exhibit tachypnea (rapid breathing), not slow breathing. D. Bradycardia ✘ No – Infection and hypoxia usually cause tachycardia (increased heart rate), not a slow heart rate.
31
Laboratory test results for COPD

One-half the internal diameter of the tracheostomy tube ## Footnote This ensures proper suctioning without obstruction.
49
Before performing postural drainage, what should the nurse check?
Check gastric residual if the patient is receiving tube feeding ## Footnote This prevents aspiration during the procedure.
50
What is a typical presentation for a patient with chronic bronchitis?
Productive cough with copious secretions ## Footnote This is a hallmark symptom of chronic bronchitis.
51
What is the primary difference between obstructive and restrictive lung diseases?
Obstructive diseases affect expiration, while restrictive diseases affect inspiration ## Footnote This distinction is crucial for diagnosis.
52
What should be done during hyper-oxygenation before suctioning?
Administer 100% oxygen for 30-60 seconds ## Footnote This prepares the patient for the procedure.
53
What would a patient with asthma in an acute exacerbation likely exhibit?
Wheezing ## Footnote Wheezing is due to narrowed airways.
54
What is the purpose of incentive spirometry?
Promote lung expansion ## Footnote This helps prevent atelectasis postoperatively.
55
A patient with pneumonia is classified as having what type of respiratory disorder?
A restrictive respiratory disorder ## Footnote Pneumonia leads to decreased lung compliance.
56
When teaching pursed-lip breathing, the nurse instructs the patient to:

60
What position should a patient be in for postural drainage of the lower lobes?
In Trendelenburg position ## Footnote This position allows gravity to assist in drainage.
61
A patient with COPD who develops respiratory acidosis would have:
Decreased pH, increased PaCO2 ## Footnote This indicates hypoventilation.
62
What is the primary purpose of a tracheostomy?
Provide long-term airway support ## Footnote It is often used for patients requiring prolonged ventilation.
63
What would a patient with emphysema be expected to have?
Destruction of alveolar walls ## Footnote This leads to decreased surface area for gas exchange.
64
When performing chest physiotherapy, the nurse should:
Percuss each area for 3-5 minutes ## Footnote This duration is effective for mobilizing secretions.
65
What is the action of an inhaled corticosteroid for a patient with asthma?
Reduces inflammation in the airways ## Footnote This helps control asthma symptoms.
66
What is the nurse's priority when caring for a patient with a tracheostomy?
Maintaining a patent airway ## Footnote Ensuring airway patency is critical for patient safety.
67
What is the primary purpose of chest physiotherapy (CPT)?
To loosen respiratory secretions and move them into central airways ## Footnote Reduces the risk for respiratory infections and atelectasis.
68
Which area should be avoided during percussion in chest physiotherapy?
Sternum ## Footnote To prevent injury to structures such as the breasts, sternum, spinal column, and kidneys.
69
How long should a client typically remain in each position during postural drainage?
10-15 minutes ## Footnote This time may be shorter initially and gradually increased as the client's tolerance improves.
70
When is the best time to schedule postural drainage?
When the client's stomach is empty ## Footnote To avoid gastric reflux and vomiting.
71
What technique is used after percussion to increase the turbulence of exhaled air?
Vibration
72
What is the recommended duration for applying suction during airway suctioning?
10-15 seconds ## Footnote To minimize hypoxia.
73
What is an advantage of a closed in-line suction system?
It reduces the risk of infection and oxygen desaturation ## Footnote Does not require disconnecting the ventilator or oxygen source.
74
What is the current recommendation regarding instilling 0.9% sodium chloride prior to suctioning?
It is no longer recommended ## Footnote No conclusive evidence that it facilitates secretion removal and may increase infection risk.
75
How long should you wait between suction passes?
At least one minute
76
Which type of suction catheter is used to clear secretions from the mouth or oropharynx?
Yankauer tonsil tip
77
What technique should be used during nasotracheal suctioning?
Surgical asepsis (sterile technique) ## Footnote Important because the trachea is considered sterile.
78
When suctioning a client with both tracheal and oral secretions, which area should be suctioned last?
Mouth/oropharynx ## Footnote Considered clean, not sterile.
79
What is the purpose of hyperinflating and/or hyperoxygenating a client prior to suctioning?
To prevent oxygen desaturation
80
Which personal protective equipment (PPE) is necessary when performing suctioning?
Gloves, goggles or face shield
81
When using a closed in-line suction system, when should suction be applied?
While withdrawing the catheter
82
What indicates that the catheter is fully withdrawn in a closed in-line suction system?
A black mark on the catheter
83
How much 0.9% sodium chloride should be used to rinse the inner lumen of a suction catheter?
5-10 mL
84
What is a complication of suctioning?
Hypoxia
85
What is the purpose of vibration during chest physiotherapy?
To increase turbulence of exhaled air
86
How should your hands be positioned when performing percussion?
Cupped with fingers and thumb together
87
Which of the following is NOT a component of chest physiotherapy?
Incentive spirometry
88
What is the correct technique for vibration during chest physiotherapy?
Apply vibration during exhalation
89
What is the primary purpose of an oropharyngeal airway?
To keep the upper airway patent
90
Which type of airway does not stimulate the gag reflex?
Nasopharyngeal airway: NPAs are commonly used in situations where patients may have difficulty breathing, such as when they are unconscious, have a gag reflex, or have difficulty opening their mouth. They can also be used to facilitate bag-valve-mask ventilation ## Footnote Made of soft, flexible rubber material.
91
What is a potential complication of tracheostomy tube placement?
Pneumothorax
92
When using a closed in-line suction system, why is the catheter usually not rotated?
Due to the protective catheter sheet
93
What is the primary nursing priority after tracheostomy tube placement?
Maintaining a patent airway
94
Which of the following is a contraindication for postural drainage?
Recent meal
95
How often is postural drainage commonly performed?
Two or three times a day
96
What should be done before starting postural drainage?
Evaluate the client's tolerance of various positions
