Self-Monitoring And Administration Devices - NAPLEX

Avoid that area; absorption is unpredictable and dosing may be unreliable. Lipohypertrophied tissue alters insulin pharmacokinetics, so avoidance ensures predictable dosing and glycemic response.

Multiple daily injections. This abbreviation refers to a regimen involving several insulin doses per day to mimic physiologic insulin secretion.

Rapidly changing glucose (post-meal, post-exercise, or after insulin). Alternate sites like the forearm or thigh exhibit a lag in glucose changes, leading to discrepancies during rapid fluctuations.

Clean/dry site → lance → apply blood to strip → read result. This sequence ensures hygienic sampling, proper blood application, and accurate meter interpretation for reliable results.

Use a new lancet and avoid the fingertip pad/center. Fresh lancets prevent infection and dullness, while avoiding the pad reduces nerve irritation and long-term damage.

Glucose contamination on fingers (not washing hands). Residual glucose from food or products on unwashed hands can contaminate the sample, inflating the measured value.

Wash with soap and water and dry completely. Proper cleaning removes contaminants that could skew glucose readings, ensuring sample integrity for accurate testing.

Keep strips sealed, dry, and at room temperature. These conditions protect enzymes on strips from moisture, heat, and air, maintaining their reactivity and accuracy.

Verify meter and strip performance within control range. Control solutions confirm the meter's calibration and strip functionality, ensuring readings fall within expected ranges.

New meter/strips, after drops, or when results do not match symptoms. Testing at these times detects potential malfunctions or degradation, safeguarding the reliability of glucose measurements.

Extremes of hematocrit (anemia or polycythemia). High or low hematocrit alters blood viscosity, interfering with the meter's enzymatic reaction and glucose detection.

Acetaminophen may falsely elevate readings on some CGMs. Acetaminophen interferes with the sensor's electrochemical signal in certain systems, leading to overestimated glucose levels.

Continuous glucose monitoring. This term describes real-time tracking of glucose levels using subcutaneous sensors for ongoing diabetes management.

CGM measures interstitial glucose with a time lag vs blood glucose. Interstitial fluid glucose trails blood glucose by 5-15 minutes due to diffusion time, causing temporary discrepancies.

Rapidly rising or falling trend arrows with symptoms or alerts. Trend arrows indicate dynamic changes where CGM lag may amplify errors, necessitating blood confirmation for safe dosing.

Trend data and hypoglycemia alerts with time-in-range assessment. CGM provides continuous insights and proactive alerts, enabling better glycemic control through time-in-range metrics.

Percent of time glucose is $70$–$180$ mg/dL. This metric quantifies glycemic stability within the target range, guiding therapy adjustments for optimal diabetes control.

Abdomen (avoid $2$ inches around the navel). The abdomen offers rapid absorption due to high vascularity, but avoiding the navel prevents inconsistent uptake from scar tissue.

Rotate within the same anatomic area to reduce lipohypertrophy. Systematic rotation within areas maintains consistent absorption and prevents tissue buildup from repeated trauma.

Lipohypertrophy. Repeated injections cause fat tissue hypertrophy, leading to hardened areas that impair insulin absorption.

Insulin pen. Pens allow precise dosing via a dial mechanism, improving convenience and accuracy over traditional syringes.

Prime with $2$ units (or per product labeling) until a drop appears. Priming expels air bubbles and ensures the needle is clear, guaranteeing full and accurate dose delivery.

Draw up clear (regular) before cloudy (NPH): “clear to cloudy”. This order prevents NPH particles from contaminating the clear insulin vial, preserving purity and stability.

Self-monitoring of blood glucose. This acronym denotes the patient-led process of regularly assessing blood sugar levels to manage diabetes effectively.
