Question

A nurse is assessing a client who has developed atelectasis postoperatively. Which of the following findings should the nurse expect

Answer 1

Correct Answers:

Increasing dyspnea

Rationale :

👉 Atelectasis is the collapse of alveoli in the lungs, leading to impaired gas exchange.

👉 As alveoli collapse, there is a decrease in oxygenation (hypoxemia).

👉 The body responds with increasing shortness of breath (dyspnea).

👉 This is one of the earliest and most common clinical signs of atelectasis.

👉 The client may also show tachypnea and decreased oxygen saturation.

👉 Dyspnea occurs due to the lungs’ reduced ability to expand and exchange gases effectively.

👉 Postoperative patients are at high risk due to immobility and shallow breathing.

👉 Therefore, increasing dyspnea is the expected finding.

❌ Friction rub

👉 A friction rub is associated with pleuritis or pericarditis, not atelectasis.

👉 Atelectasis does not involve pleural inflammation causing rubbing sounds.

❌ Facial flushing

👉 Facial flushing is not a typical sign of lung collapse or impaired ventilation.

👉 It is more associated with vasodilation or fever-related conditions.

❌ Decreasing respiratory rate

👉 Atelectasis typically causes increased respiratory rate (tachypnea) as compensation.

👉 A decreasing respiratory rate is not consistent with hypoxemia compensation mechanisms.

Answer 2

Correct Answers:

Assessing the patient's baseline cognitive function to identify any potential changes after surgery

Rationale :

In elderly patients, one of the most critical preoperative priorities is establishing a baseline cognitive status.

👉 Older adults are at high risk for postoperative delirium and cognitive decline.

👉 Knowing the baseline allows the nurse to detect new confusion, memory changes, or delirium early after surgery.

👉 Cognitive changes can indicate complications such as hypoxia, infection, or medication effects.

👉 Early identification improves patient safety and outcomes.

👉 Baseline assessment supports accurate postoperative comparison and monitoring.

👉 It is a key component of geriatric perioperative care planning.

👉 Therefore, cognitive assessment is the most important preoperative consideration.

❌ Encouraging the patient to increase fluid intake immediately before surgery

👉 Preoperative patients are usually required to restrict oral intake (NPO status).

👉 Increasing fluids could increase the risk of aspiration during anesthesia.. Performing a detailed ❌nutritional assessment to prescribe high-calorie supplements

👉 Nutritional assessment is important but not the most immediate preoperative priority.

👉 High-calorie supplementation is not typically initiated right before surgery.

❌ Ensuring the patient has fasted for at least 12 hours before surgery

👉 Preoperative fasting is important but usually follows standard anesthesia guidelines (often 6–8 hours, not always 12).

👉 It is a routine safety requirement, not the highest priority individualized assessment.

Answer 3

Correct Answers:

Exposure to gases

Rationale :

👉 Surgical staff in the operating room are exposed to waste anesthetic gases such as nitrous oxide and halogenated agents.

👉 Prolonged exposure can lead to serious health risks, including liver and kidney toxicity.

👉 It may also cause neurological symptoms such as dizziness, headaches, and fatigue.

👉 Chronic exposure has been linked to reproductive risks and miscarriage in exposed staff.

👉 Proper ventilation and scavenging systems are required to reduce occupational exposure.

👉 This is a recognized occupational health hazard in operating rooms.

👉 It directly affects staff safety over time, making it the most significant hazard listed.

👉 Therefore, exposure to anesthetic gases is the correct answer.

❌ Extended shifts without breaks

👉 This contributes to fatigue and reduced performance, but is not a direct OR environmental hazard.

👉 It is more of an administrative/work schedule issue.

❌ High humidity levels

👉 OR environments are actually maintained at controlled temperature and humidity levels.

👉 High humidity is not a typical or significant hazard in modern operating rooms.

❌ Excessive noise from patient monitors

👉 Noise may contribute to stress and distraction, but it is not a major physiological hazard.

👉 It is considered a minor environmental nuisance rather than a health hazard.

Answer 4

Correct Answers:

Maintaining proper communication and coordination among the surgical team regarding the use of electrical equipment and flammable agents.

Rationale :

👉 Surgical fires occur due to the fire triangle: oxygen, ignition source, and fuel.

👉 Effective communication ensures the team is aware of electrosurgical devices, lasers, and flammable prep solutions.

👉 Coordination helps prevent simultaneous presence of oxygen-rich environments and ignition sources.

👉 It reduces risk of accidental ignition during procedures like cauterization or laser use.

👉 Team communication allows safe timing of skin prep drying and oxygen adjustments.

👉 This is the most critical and evidence-based prevention strategy.

👉 Fire safety protocols in the OR heavily emphasize team awareness and coordination.

👉 Therefore, communication and coordination is the best preventive measure.

❌ Using alcohol-based skin antiseptics in a well-ventilated area

👉 Alcohol-based solutions are actually a known fire risk when not fully dried.

👉 Ventilation alone does not eliminate the danger of flammable vapors near ignition sources.

❌ Increasing the oxygen concentration in the operating room to ensure adequate supply for patients

👉 High oxygen concentration significantly increases the risk of surgical fires.

👉 Oxygen acts as an accelerant in the fire triangle, making combustion easier.

❌ Ensuring all surgical instruments are sterilized before the procedure

👉 Sterilization prevents infection, not fires.

👉 It does not address the key components of ignition, fuel, or oxygen.

Answer 5

Correct Answers:

A client who is postoperative following thoracic surgery.

Rationale :

👉 Atelectasis is caused by collapse of alveoli due to poor ventilation.

👉 After thoracic surgery, clients often experience pain that limits deep breathing and coughing.

👉 This leads to shallow respirations and decreased lung expansion.

👉 Mucus may accumulate, increasing risk of airway obstruction and alveolar collapse.

👉 Postoperative immobility further contributes to reduced lung inflation.

👉 This makes thoracic surgery patients highly susceptible to postoperative atelectasis.

👉 Incentive spirometry is commonly used to prevent this complication.

👉 Therefore, this client is at highest risk.

❌ A client who is receiving IV fluids

👉 IV fluids do not directly affect lung expansion or alveolar collapse.

👉 This does not increase risk for atelectasis.

❌ A client who has a history of heart failure

👉 Heart failure primarily leads to fluid overload and pulmonary edema, not alveolar collapse.

👉 It is not a primary risk factor for atelectasis.

❌ A client who has a urinary tract infection

👉 UTI affects the urinary system, not respiratory function.

👉 It has no direct link to alveolar collapse or atelectasis.

Answer 6

Correct Answers:

Encourage the client to increase fluid intake.

Rationale :

👉 In pneumonia, secretions become thick and difficult to expectorate due to infection and inflammation.

👉 Increasing fluid intake helps hydrate respiratory secretions, making them thinner and easier to cough up.

👉 Thin secretions improve airway clearance and oxygen exchange.

👉 Adequate hydration supports mucociliary function in the lungs.

👉 It reduces the risk of mucus plugging and atelectasis.

👉 Fluids can include water, warm teas, and broths to promote comfort.

👉 This is a direct and effective method to improve secretion mobility.

👉 Therefore, increasing fluid intake is the best action.

❌ Encourage the client to ambulate frequently

👉 Ambulation helps with lung expansion and ventilation, not directly thinning secretions.

👉 It is supportive but not the primary action for secretion thinning.

❌ Encourage regular use of the incentive spirometer

👉 Incentive spirometry improves alveolar expansion and prevents atelectasis.

👉 It does not directly affect mucus viscosity or thinning.

❌ Encourage coughing and deep breathing

👉 This helps mobilize secretions, but does not thin them.

👉 Thick secretions may still be difficult to expectorate without hydration.

Answer 7

Correct Answers:

Encourage the client to use an incentive spirometer.

Rationale :

👉 Immobility increases risk for alveolar collapse due to shallow breathing.

👉 An incentive spirometer promotes deep inhalation and full lung expansion.

👉 It helps reopen collapsed alveoli and prevents atelectasis formation.

👉 It improves oxygenation and ventilation distribution in the lungs.

👉 Regular use supports mucus clearance and airway patency.

👉 It is a standard postoperative and immobile patient intervention.

👉 It reduces complications such as hypoxemia and pulmonary infection.

👉 Therefore, incentive spirometry is the best preventive measure.

❌ Administer opioid analgesics as prescribed

👉 Opioids can suppress the respiratory drive.

👉 They may worsen hypoventilation and increase atelectasis risk.

❌ Place the client in a supine position

👉 Supine positioning promotes lung compression and reduced expansion.

👉 It increases risk of secretion pooling and alveolar collapse.

❌ Restrict fluid intake

👉 Fluid restriction leads to thick secretions, making lung clearance harder.

👉 This increases risk of mucus plugging and atelectasis.

Answer 8

Correct Answers:

Nociceptive pain is typically described as burning or tingling.

Rationale :

Neuropathic pain results from damage or dysfunction of the peripheral or central nervous system.

👉 It is commonly described as burning, tingling, shooting, or electric shock–like sensations.

👉 This type of pain occurs even without direct tissue injury stimulation.

👉 It is caused by abnormal nerve signaling or hypersensitivity of nerves.

👉 Patients often report paresthesia or dysesthesia.

👉 It does not follow typical inflammatory or injury patterns.

👉 It often persists even after tissue healing has occurred.

👉 Therefore, burning or tingling is the key feature of neuropathic pain.

❌ Neuropathic pain results from activation of nociceptors due to tissue damage

👉 This describes nociceptive pain, not neuropathic pain.

👉 Nociceptors respond to actual tissue injury or inflammation.

❌ Pain is associated with damage to or inflammation of somatic or visceral tissues

👉 This is also a definition of nociceptive pain.

👉 It involves tissue injury, not nerve dysfunction.

❌ Nociceptive pain is typically described as aching or throbbing

👉 This statement is correct for nociceptive pain but does not differentiate neuropathic pain specifically in the question.

👉 The question asks for the key distinguishing feature of neuropathic pain.

Answer 9

Correct Answers:

D-dimer blood test
CT scan
Lung ventilation and perfusion scan (VQ scan)

Rationale :

🧠 D-dimer blood test (Correct Answer)

👉 D-dimer measures fibrin degradation products, which increase when there is active clot formation and breakdown.

👉 It is highly sensitive for suspected pulmonary embolism (PE).

👉 A normal D-dimer can help rule out PE in low-risk patients.

👉 Elevated levels indicate possible thromboembolic activity.

👉 It is used as a screening tool, not definitive diagnosis.

👉 It helps guide need for further imaging studies.

👉 Therefore, it is part of PE diagnostic workup.

🧠 CT scan (CT pulmonary angiography) (Correct Answer)

👉 CT pulmonary angiography is the gold standard imaging test for PE diagnosis.

👉 It directly visualizes clots in pulmonary arteries.

👉 It provides detailed images of lung vasculature and obstruction sites.

👉 It is highly accurate and widely used in emergency settings.

👉 It helps confirm diagnosis and guide immediate treatment decisions.

👉 Therefore, it is a key confirmatory test for PE.

🧠 Lung ventilation and perfusion scan (V/Q scan) (Correct Answer)

👉 V/Q scan evaluates airflow (ventilation) and blood flow (perfusion) in the lungs.

👉 A mismatch (normal ventilation but poor perfusion) suggests pulmonary embolism.

👉 It is especially useful when CT scan is contraindicated (e.g., contrast allergy, renal failure).

👉 It helps detect areas of blocked pulmonary circulation.

👉 It is a validated diagnostic test for PE.

👉 Therefore, it is included in PE confirmation testing.

❌ Complete blood count (CBC)

👉 CBC may show non-specific findings such as mild leukocytosis or anemia.

👉 It does not confirm or diagnose pulmonary embolism.

❌ Chest x-ray

👉 Chest x-ray is often normal in PE or shows non-specific changes.

👉 It is mainly used to rule out other causes of symptoms (e.g., pneumonia, pneumothorax).

Answer 10

Correct Answers:

Malignant hyperthermia

Rationale :

👉 Malignant hyperthermia is a life-threatening hypermetabolic reaction to certain anesthetic agents (e.g., succinylcholine, volatile anesthetics).

👉 Early signs include sudden tachycardia and rapidly increasing end-tidal CO₂ levels.

👉 Muscle rigidity (especially masseter spasm) is a hallmark feature.

👉 It causes a hypermetabolic state leading to increased oxygen consumption and CO₂ production.

👉 Without treatment, it can progress to hyperthermia, acidosis, and cardiac arrest.

👉 It requires immediate administration of dantrolene (specific antidote).

👉 It is a true perioperative emergency requiring rapid recognition.

👉 Therefore, malignant hyperthermia is the most likely complication.

❌ Hypovolemic shock

👉 Causes tachycardia and hypotension, but not muscle rigidity or rapid CO₂ rise.

👉 Typically related to blood loss or fluid depletion, not anesthesia reaction.

❌ Anaphylactic reaction

👉 Causes bronchospasm, hypotension, and rash/urticaria.

👉 Muscle rigidity and increased CO₂ are not typical features.

❌ Pulmonary embolism

👉 Causes sudden hypoxia, dyspnea, and tachycardia.

👉 Does not present with muscle rigidity or marked CO₂ elevation intraoperatively.
