• A patient with asthma has a personal best peak expiratory flow rate (PEFR) of 400 L/min. When

explaining the asthma action plan, the nurse will teach the patient that a change in therapy is

neededwhen the PEFR is less than L/minute

ANS: 320

A PEFR less than 80% of the personal best indicates that the patient is in the yellow zone

wherechanges in therapy are needed to prevent progression of the airway narrowing.

Which statement by a nurse to a

patient newly diagnosed with type 2 diabetes is correct?

• Insulin is not used to control blood glucose in patients with type 2 diabetes.

• Complications of type 2 diabetes are less serious than those of type 1 diabetes.

• Changes in diet and exercise may control blood glucose levels in type 2 diabetes.

• Type 2 diabetes is usually diagnosed when the patient is admitted with

ahyperglycemic coma.

ANS: C

Forsome patients with type 2 diabetes, changes in lifestyle are sufficient to achieve

bloodglucose control. Insulin is frequently used for type 2 diabetes, complications are

equally severe as for type 1 diabetes, and type 2 diabetes is usually diagnosed with

routine laboratory testing or after a patient develops complications such as frequent

yeast infections.

• A patient screened for diabetes at a clinic has a fasting plasma glucose level of 120

mg/dL(6.7 mmol/L). The nurse will plan to teach the patient about

• self-monitoring of blood glucose.

• using low doses of regular insulin.

• lifestyle changes to lower blood glucose.

• effects of oral hypoglycemic medications.

ANS: C

The patient’s impaired fasting glucose indicates prediabetes, and the patient should be

counseled about lifestyle changesto prevent the development of type 2 diabetes. The

patientwith prediabetes does not require insulin or oral hypoglycemics for glucose control

and does not need to self-monitor blood glucose.

• A 28-yr-old male patient with type 1 diabetes reports how he manages his exercise

andglucose control. Which behavior indicates that the nurse should implement

additional teaching?
