A patient who was involved in a motor vehicle crash has had a tracheostomy placed to allow for continued mechanical ventilation. How should the nurse interpret the following arterial blood gas results: pH 7.48, PaO₂ 85 mm Hg, PaCO₂ 32 mm Hg, and HCO₃ 25 mEq/L?

Patient Profile:

• Name: Mr. John Smith
• Age: 68 years
• Medical History: Osteoarthritis of the hip, Type 2 diabetes, hypertension, and atrial fibrillation
• Current Medications: Lisinopril, Metformin, Warfarin
• Surgical Procedure: Total hip replacement (THR) due to severe pain and limited mobility.

Preoperative Care:

• The nurse conducts a comprehensive assessment, including a physical examination, vital signs, and a review of Mr. Smith's medical history.
• Preoperative labs are ordered with the following abnormal values noted:
  • Complete Blood Count (CBC):
    1. Hemoglobin: 12.0 g/dL (normal range: 13.5-17.5 g/dL)
    2. Hematocrit: 36% (normal range: 38.8-50%)
  • Basic Metabolic Panel (BMP):
    1. Serum Creatinine: 3 mg/dL (normal range: 0.6-1.2 mg/dL)
    2. Blood Urea Nitrogen (BUN): 24 mg/dL (normal range: 7-20 mg/dL)

• • Coagulation Studies:
    1. INR: 5 (normal range: 0.8-1.1)

Intraoperative Care:

• The scrub nurse assists in positioning Mr. Smith on the operating table.
• The surgical team completes the time-out procedure.
• The surgeon states the estimated blood loss at 300 ml.
• The anesthesiologist reports a stable blood pressure of 120/64.

Postoperative Care:

• Mr. Smith is transferred to the Post Anesthesia Care Unit (PACU) for close monitoring of his recovery from anesthesia.
• Once fully recovered from surgery, Mr. Smith is transferred to the orthopedic unit where the orthopedic unit nurse starts the ordered morphine PCA.

Patient Profile:

• Name: Sarah Johnson
• Age: 54
• Diagnosis: Metastatic breast cancer, Stage IV, diagnosed six months ago with metastasis to the liver and bone

Treatment Plan:

• Surgery: Lumpectomy with axillary lymph node dissection
• Chemotherapy: Adriamycin and Cyclophosphamide (AC) regimen
• Radiation Therapy: Targeted treatment to the chest wall post-surgery

Clinical Presentation:

Subjective Data:

• Reports of nausea and vomiting, especially after chemotherapy sessions
• Expresses feelings of sadness and fear regarding her prognosis and the impact on her family
• States she has lost 10 pounds in the last month due to decreased appetite and nausea
• Describes pain in the surgical area and generalized body pain that worsens at night
• Mentions experiencing a red, itchy rash on her chest from radiation therapy

Objective Data:

• Vital signs: HR 78 bpm, BP 120/80 mmHg, Temp 98.6°F
• Weight: 135 lbs (down from 145 lbs)
• Physical examination reveals tenderness in the left breast and axilla, and a rash in the radiation field
• Labs: Mild anemia (Hgb 10.5 g/dL), elevated liver enzymes

Nursing Diagnoses:

1. Nausea related to chemotherapy as evidenced by patient report and vomiting episodes
2. Imbalanced Nutrition: Less than Body Requirements related to nausea and weight loss as evidenced by a 10-pound weight loss and decreased appetite
3. Acute Pain related to surgical procedure and cancer

What intervention can the nurse implement to help manage Sarah's nausea?
