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.

During the post-op period, what four potential complications should be monitored?

Choice A reason: Checking the patient's temperature is important for assessing the severity of the pneumonia and monitoring for fever, but it is not the priority action before administering the first dose of vancomycin.

Choice B reason: Obtaining sputum cultures is the priority action because it allows for the identification of the causative organism and determination of its antibiotic susceptibility. This helps ensure that the prescribed antibiotic is appropriate for the patient's infection. Cultures should be obtained before starting antibiotic therapy to avoid interference with culture results.

Choice C reason: Checking the patient's blood pressure is important for overall patient assessment and monitoring, especially considering potential side effects of vancomycin. However, it is not the primary action needed before the first dose of the antibiotic.

Choice D reason: Drawing a blood specimen to evaluate the white blood cell count is useful for assessing the severity of the infection and the patient's immune response. However, this can be done after obtaining the sputum cultures and is not the immediate priority before administering the antibiotic.

Choice A reason: Hypertension, often called the "silent killer," is usually asymptomatic until significant target organ damage has occurred. This means that many people with hypertension do not experience symptoms until their blood pressure has been high for a long time, leading to damage in organs such as the heart, kidneys, brain, and eyes. Therefore, it's crucial for patients to understand the importance of regular blood pressure monitoring and management even in the absence of symptoms.

Choice B reason: While annual BP checks are useful for monitoring treatment effectiveness, more frequent monitoring may be necessary for newly diagnosed patients or those with poorly controlled hypertension. This information is important but not the most critical point compared to understanding the asymptomatic nature of hypertension.

Choice C reason: Increasing physical activity can help control blood pressure for many individuals, but it is not universally effective for everyone. While important, this information is part of a broader lifestyle modification plan rather than the single most critical point to emphasize.

Choice D reason: Dietary changes can play a significant role in controlling blood pressure, but not all individuals can control their BP through diet alone. Emphasizing this may give a false sense of control without highlighting the importance of medication and other interventions when needed.
