26
Q

How is insulin measured in the US?

A

In units. For example, U-100 means there are 100 units of insulin in each mL of liquid

32
Q

When should a meal be eaten with rapid acting insulin?

A

35

How long is food actively raising blood sugar?

A

1-2 hours after eating

36
Q

What color is

Intermediate acting insulin?

A

Cloudy white (cloudy bc a substance has been added to slow down its action)

Must be mixed gently and thoroughly before injection is prepared—roll between palms, do not shake

37
Q

How is NPH typically prescribed to be taken?

A

Once or twice a day

38
Q

In what situation would

NPH be beneficial taken at bedtime?

A

Would peak during early morning hours when liver is releasing too much glucose

39
Q

What color is long acting insulin?

A

Clear

40
Q

When is long acting insulin usually prescribed to be taken?

A

Once daily often at bedtime. Can be taken any time day or night as long as timing is consistent

41
Q

What are the strength of premixed NPH insulins?

A

Intermediate and short acting combined. First number in name indicates amount of intermediate insulin, second number amount of short acting

(Ex: 70/30, 75/25, 50/50)

42
Q

What type of insulin is afrezza?

A

Inhaled, rapid acting.
Comes in cartridges of 4,8, and 12 units
*lung function should be monitored

Be mixed?
