Regular insulin, lispro, aspart and glulisine can be used for this purpose. Regular insulin should be given with about a 30-minute lead-time prior to the meal to be maximally effective and to minimize the possibility of hypoglycemia. Lispro, aspart and glulisine are approved for dosage with the first bite of the meal, and may even be effective if given after completing the meal. The short-acting insulin is also used to correct hyperglycemia.The usual schedule for checking fingerstick blood glucose and administering insulin is before all meals and sometimes also at bedtime. More recent guidelines also call for a check 2 hours after a meal to ensure the meal has been covered effectively. Sliding scales
First described in 1934, what physicians typically refer to as sliding-scale insulin (SSI) is fast- or rapid-acting insulin only, given subcutaneously, typically at meal times and sometimes bedtime, but only when blood glucose is above a threshold (e.g. 10 mmol/L, 180 mg/dL). The so-called "sliding-scale" method is widely taught, although it has been heavily criticized. Sliding scale insulin (SSI) is not an effective way of managing long-term diabetes in individuals residing in nursing homes. Sliding scale insulin leads to greater discomfort and increased nursing time. Sample regimen using insulin glargine and insulin lispro:

Insulin glargine: 20 units at bedtime

Carb counting and DAFNE
A more complicated method that allows greater freedom with meal times and snacks is "carb counting." This approach is taught to people who are diabetic in the UK and elsewhere as "Dose Adjustment For Normal Eating" or DAFNE.
The exam includes stimuli at four different frequencies (500, 1000, 2000, and 4000 Hz) and white noise clicks of 50 ms duration. It is a useful test because it provides an index of auditory temporal resolution. In children, an overall gap detection threshold greater than 20 ms means they have failed and may have an auditory processing disorder based on abnormal perception of sound in the time domain. Gaps in Noise Test (GIN) also measures temporal resolution by testing the patients gap detection threshold in white noise. Pitch Patterns Sequence Test (PPT) and Duration Patterns Sequence Test (DPT) measure auditory pattern identification. The PPS has s series of three tones presented at either of two pitches (high or low). Meanwhile, the DPS has a series of three tones that vary in duration rather than pitch (long or short). Patients are then asked to describe the pattern of pitches presented. Masking Level Difference (MLD) at 500 Hz measures overlapping temporal processing, binaural processing, and low-redundancy by measuring the difference in threshold of an auditory stimulus when a masking noise is presented in and out of phase. The Staggered Spondaic Word Test (SSW) is one of the oldest tests for APD developed by Jack Katz. Although it has fallen into some disuse by audiologists as it is complicated to score, it is one of the quickest and most sensitive tests to determine APD. Modality-specificity and controversies
The issue of modality-specificity has led to considerable debate among experts in this field.
