Study Notes

Hemoglobin A1C

  • Hemoglobin A1C (Hgb A1c) indicates the average blood glucose control over the past three months.

Laboratory Values in Physical Therapy

  • Physical therapists should recognize the importance of the time and trend when laboratory specimens are drawn.

Management of Patients with Atrial Fibrillation

  • In cases of significant hemoglobin drop and high INR (5.1), the appropriate action is to hold physical therapy evaluation and consult with the healthcare team.

Cognition and Therapy in Cirrhosis

  • A patient with cirrhosis showing an increasing ammonia level (from 80 μg/dL to 90 μg/dL) is likely to exhibit changes in fine motor control during therapy sessions.

Acid-Base Imbalance in Asthma Patients

  • An asthmatic patient with a PaCO2 of 56 mmHg, HCO3 of 24 mmol/L, and PaO2 of 60 mmHg is expected to have a pH of 7.25, indicating a state of acidosis with no compensation.

Platelet Count Management

  • A patient with a platelet count of 150 K/μL should have limitations on activities that could risk bleeding or injury, depending on the clinical context.
