28 Feb Clinical Nursing Scenario: Sickle Cell Disease with Pneumonia

Name: Mr. J.T. Age: 24 years Gender: Male Medical History:

· Homozygous sickle cell disease (HbSS)

· Multiple prior vaso-occlusive crises

· History of acute chest syndrome

· Functional asplenia

· Up to date on pneumococcal vaccination

Chief Complaint

“Chest pain, fever, and shortness of breath for 2 days.”

History of Present Illness

Mr. J.T. presents to the emergency department with worsening pleuritic chest pain, productive cough with yellow sputum, fever, and increasing fatigue. He reports pain similar to prior sickle cell crises but notes new shortness of breath.

He rates his pain as 8/10 in the chest and lower back. He has been taking home oxycodone with minimal relief.

Interpretation: Metabolic acidosis with hypoxemia

Diagnostic Imaging

· Chest X-ray: Right lower lobe infiltrate consistent with pneumonia; concern for early acute chest syndrome.

Nursing Priorities

1. Impaired Gas Exchange

Related to: Pneumonia and sickling in pulmonary vasculature

· Apply oxygen (2–4 L NC, titrate to keep SpO₂ >94%)

· Continuous pulse oximetry

· Monitor for signs of acute chest syndrome

2. Acute Pain

Related to: Vaso-occlusive crisis

· Administer IV opioids (e.g., morphine PCA)

· Assess pain every 1–2 hours

· Encourage hydration

3. Infection Management

· Obtain blood and sputum cultures

· Administer IV broad-spectrum antibiotics (e.g., ceftriaxone + azithromycin)

· Monitor WBC and temperature trends

4. Risk for Sepsis

Monitor for:

· Worsening hypotension

· Decreased urine output

· Altered mental status

· Rising lactate levels

Provider Orders

· Oxygen via nasal cannula

· IV normal saline at 125 mL/hr

· IV morphine PCA

· IV ceftriaxone and azithromycin

· Incentive spirometer every 2 hours while awake

· Repeat CBC and ABG in 6 hours

· Type and crossmatch (possible transfusion if Hgb <7 or worsening hypoxia)

Possible Complications

· Acute chest syndrome

· Sepsis

· Acute kidney injury

· Respiratory failure

Teaching Points for Nursing Students

· Patients with sickle cell disease are at high risk for severe infections due to functional asplenia.

· Pneumonia in sickle cell patients can rapidly progress to acute chest syndrome.

· Early oxygenation, hydration, antibiotics, and pain control are critical.

· Monitor closely for rapid deterioration.
