Hint : 💉 48-72 hours for accurate results

Correct Answers:

  • Inform the client to return for an evaluation of redness 24-36 hours after
  • Ask the client about a history of receiving the Bacille Calmette-Guerin vaccine.
  • Instruct the client that they will need to return in 48-72 hours.


Rationale :

Inform the client to return for an evaluation of redness 24-36 hours after

✍️ Tuberculin skin tests (TST) require the client to return 24-72 hours after administration to assess for reaction.

✍️ Redness and induration (raised area) will be evaluated to determine if the client has been exposed to tuberculosis.

✍️ No evaluation should be made too soon, as it may not show a clear reaction in the early stages.

Ask the client about a history of receiving the Bacille Calmette-Guerin vaccine

◈ The BCG vaccine (used in countries with high tuberculosis rates) can cause a false positive on the tuberculin skin test.

◈ Understanding the client's vaccination history helps the nurse interpret test results accurately and differentiate between a true positive and a vaccine response.

◈ If the client received the BCG vaccine, further testing may be necessary to confirm the diagnosis.

Instruct the client that they will need to return in 48-72 hours

🍃 Tuberculin skin test evaluation should be performed 48-72 hours after administration to ensure proper measurement of redness or induration.

🍃 The reaction can be measured at this time for accurate results regarding exposure to tuberculosis.

🍃 Less than 48 hours will not provide accurate test results, as the reaction may still be developing.

Hint : 🦠 Airborne precautions

Correct Answers:

  • Place a surgical mask on the client when being transported through the facility.
  • Don a HEPA/N95 mask before entering the room to perform patient care.
  • Keep the door to the client's room closed


Rationale :

Place a surgical mask on the client when being transported through the facility.

◈ Pulmonary tuberculosis is airborne, and the client should wear a surgical mask to prevent spreading respiratory droplets while being transported.

◈ The surgical mask reduces exposure to others during movement outside the room.

◈ Transport should be kept to a minimum to avoid unnecessary exposure to the infectious air.

Don a HEPA/N95 mask before entering the room to perform patient care.

➥ Nurses should wear a HEPA/N95 mask to protect themselves from airborne particles containing Mycobacterium tuberculosis.

➥ N95 masks are designed to filter out the small droplets that carry tuberculosis bacteria.

➥ Standard surgical masks are not sufficient for protecting from airborne tuberculosis transmission.

Keep the door to the client's room closed.

✳️ Airborne precautions require that the client be placed in a negative pressure room with the door closed to contain and filter the air inside.

✳️Keeping the door closed helps limit exposure to others and maintain a controlled environment for infection prevention.

✳️ Ventilation in the room is important to reduce airborne transmission.

Hint : 🫁 pneumonia symptoms

Correct Answers:

  • Cough and sputum color, dyspnea, chest pain


Rationale :

➡️ Cough, sputum color, dyspnea, and chest pain are classic symptoms of community-acquired pneumonia.

➡️ Pneumonia causes inflammation in the lungs, leading to increased mucus production, resulting in productive cough and changes in sputum (yellow, green, or rust-colored).

➡️ Dyspnea (difficulty breathing) and chest pain from pleuritic involvement or inflammation in the lung lining are also common complaints in pneumonia.

➡️ The other symptoms, such as diaphoresis or hunger, are not typical indicators of pneumonia.

Hint : 💨 high pH, low CO₂

Correct Answers:

  • Respiratory alkalosis


Rationale :

✳️ Respiratory alkalosis occurs when hyperventilation (rapid breathing) causes a loss of carbon dioxide (CO₂) from the blood, increasing blood pH.

✳️ The pH value of 7.5 is elevated, suggesting alkalosis.

✳️The HCO₃⁻ value of 22 mEq/L is within normal limits, indicating that the alkalosis is respiratory in origin.

✳️ The PaCO₂ level of 25 mm Hg is low, which confirms respiratory alkalosis since it represents the decreased CO₂ level in the blood.

Hint : ➥ 1 mg/kg × weight (kg)

Correct Answers:

  • 42.75


Rationale :

➥ Formula:

➡️ Dose to administer (mg) = Weight (kg)×Prescribed dose (mg/kg)

➧ Given:

Weight: 95 lbs

♦ Convert weight to kilograms:

♦95 lbs× 0.45 kg/lb = 42.75kg

Prescribed dose: 1 mg/kg

👉 Calculation:

➥42.75 kg ×1 mg/kg = 42.75mg ( rounded to the nearest tenth)

= 43.2mg

Hint : 🫁 Treat bronchospasm immediately.

Correct Answers:

  • Albuterol ipratropium nebulizer treatment


Rationale :

🔹 Albuterol is a beta-2 agonist that relaxes bronchial smooth muscle, improving airflow and relieving wheezing.

🔹 Ipratropium is an anticholinergic that decreases mucus secretion and promotes airway patency.

🔹 A combination nebulizer treatment is often indicated for bronchospasm with wheezing related to pneumonia.

🔹 This combination provides rapid relief and prevents airway obstruction progression.

Hint : 💨 Humidify oxygen over 4 L/min.

Correct Answers:

  • Attach a humidifier bottle to the oxygen delivery system


Rationale :

🟡 Oxygen at flows greater than 4 L/min can dry mucous membranes; using a humidifier prevents tissue irritation.

🟡 Humidification adds moisture, making oxygen therapy more comfortable and reducing the risk of mucosal injury.

🟡 Petroleum-based products like petroleum jelly are contraindicated because they are flammable with oxygen use.

🟡 Ensuring proper equipment setup improves client comfort and safety during therapy.

Hint : 🧪 Monitor liver closely.

Correct Answers:

  • "You will need to have liver function tests done frequently."


Rationale :

🔽 Pyrazinamide is hepatotoxic; frequent liver function monitoring is essential to detect early liver injury.

🔽 Clients taking this medication are at risk for elevated liver enzymes and hepatitis.

🔽 Education on the importance of lab monitoring helps prevent serious complications during TB treatment.

🔽 Vision testing is associated more with ethambutol, not pyrazinamide.

Hint : 📈 First check O₂ levels.

Correct Answers:

  • Determine the oxygen saturation level.


Rationale :

✔️ Acute confusion in older adults can be an early sign of hypoxia or infection.

✔️ Checking oxygen saturation helps quickly rule out respiratory compromise as a cause of mental status changes.

✔️ Rapid assessment and intervention are necessary to prevent worsening of hypoxia and further neurological deterioration.

✔️ Hydration status is important but not the immediate priority over assessing oxygenation.

Answer Options

Hint : 🏥 Isolate, test, support oxygen.

Correct Answers:

  • Call the provider to ask about ordering a chest x-ray and sputum culture.
  • Place the client in a negative pressure airborne isolation room.
  • Place the client on supplemental oxygen.


Rationale :

🟧 Call the provider to ask about ordering a chest x-ray and sputum culture

▶️ Chest x-ray and sputum culture are critical for diagnosing pneumonia or other infectious respiratory diseases.

▶️ Identifying the pathogen early improves targeted treatment and reduces complications.

🟧 Place the client in a negative pressure airborne isolation room

▶️ Symptoms like fever, productive cough, and dyspnea could suggest tuberculosis, which requires airborne precautions until ruled out.

▶️ Early isolation protects other clients and healthcare workers from possible airborne transmission.

🟧Place the client on supplemental oxygen

▶️ Even with a normal oxygen saturation, the increased respiratory rate (tachypnea) and symptoms warrant supportive oxygen to reduce respiratory effort.

▶️ Oxygen helps maintain optimal perfusion during systemic infection and inflammation.
