,1.A patient with type 1 diabetes is prescribed rapid-acting insulin before
meals. The nurse knows that this type of insulin has which of the
following characteristics?
- A) It starts to work within 15 minutes after injection and peaks in about
1 hour.
- B) It starts to work within 30 minutes after injection and peaks at 2 to 3
hours.
- C) It starts to work about 1 to 3 hours after injection and peaks in 8
hours.
- D) It starts to work several hours after injection and works for about 24
hours.
- Answer: A) It starts to work within 15 minutes after injection and peaks
in about 1 hour.
- Rationale: Rapid-acting insulin is the fastest acting type of insulin,
which is suitable for controlling blood sugar levels during meal times. It
has a short duration of action, so it needs to be taken close to the time of
eating.
2.A patient with type 2 diabetes is prescribed a pre-mixed insulin that
contains both short-acting and intermediate-acting insulin. The nurse
instructs the patient to inject the insulin how many times per day?
- A) Once, in the morning.
- B) Twice, before breakfast and dinner.
- C) Three times, before each main meal.
- D) Four times, before each main meal and at bedtime.
- Answer: B) Twice, before breakfast and dinner.
- Rationale: Pre-mixed insulin is a combination of two different types of
insulin that can control blood sugar levels at meals and between meals. It
is usually taken twice a day, before breakfast and dinner, to cover the
periods of highest blood sugar levels.
- A patient with type 1 diabetes is admitted to the hospital with diabetic
ketoacidosis (DKA). The nurse expects that the patient will receive which
type of insulin through intravenous (IV) infusion?
- A) Rapid-acting insulin
- B) Short-acting insulin
, - C) Intermediate-acting insulin
- D) Long-acting insulin
- Answer: B) Short-acting insulin
- Rationale: Short-acting insulin is the only type of insulin that can be
given intravenously, as it has a clear solution and a predictable onset and
duration of action. It is used for emergency situations such as DKA, where
a fast and continuous delivery of insulin is needed to lower blood sugar
levels and correct acidosis.
3. A patient with type 2 diabetes is prescribed long-acting insulin once
daily at bedtime. The nurse teaches the patient that this type of insulin has
which of the following advantages?
- A) It mimics the body's natural pattern of insulin release throughout the
day.
- B) It reduces the risk of nocturnal hypoglycemia and weight gain.
- C) It allows for more flexibility in meal timing and carbohydrate intake.
- D) All of the above.
- Answer: D) All of the above.
- Rationale: Long-acting insulin is a basal insulin that provides a steady
low level of insulin for about 24 hours. It mimics the body's natural
pattern of insulin release between meals and during fasting. It reduces the
risk of nocturnal hypoglycemia and weight gain compared to
intermediate-acting insulin. It also allows for more flexibility in meal
timing and carbohydrate intake compared to short-acting or rapid-acting
insulin.
4.A patient with type 1 diabetes is using an insulin pump that delivers
rapid-acting insulin continuously throughout the day. The nurse instructs
the patient to adjust the basal rate and bolus dose of insulin based on
which of the following factors?
- A) Blood glucose levels
- B) Carbohydrate intake
- C) Physical activity
- D) All of the above.
- Answer: D) All of the above.
- Rationale: An insulin pump is a device that delivers rapid-acting
insulin through a catheter under the skin. The pump has two modes of
delivery: basal rate and bolus dose. The basal rate is a constant low dose
