1. 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 needed
when 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 where
changes 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?
a) Insulin is not used to control blood glucose in patients with type 2 diabetes.
b) Complications of type 2 diabetes are less serious than those of type 1 diabetes.
c) Changes in diet and exercise may control blood glucose levelsin type 2 diabetes.
d) Type 2 diabetes is usually diagnosed when the patient is admitted with a
hyperglycemic coma.
ANS: C
For some patients with type 2 diabetes, changes in lifestyle are sufficient to achieve blood
glucose 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.
2. 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
a) self-monitoring of blood glucose.
b) using low doses of regular insulin.
c) lifestyle changes to lower blood glucose.
d) 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 patient
with prediabetes does not require insulin or oral hypoglycemics for glucose control and does
not need to self-monitor blood glucose.
3. A 28-yr-old male patient with type 1 diabetes reports how he manages his exercise and
glucose control. Which behavior indicates that the nurse should implement additional
teaching?
a) The patient always carries hard candies when engaging in exercise.
b) The patient goes for a vigorous walk when his glucose is 200 mg/dL.
