FINAL EXAM STUDY GUIDE & PRACTICE TEST 2026/2027
A patient who has type 2 diabetes is being prepared for an elective coronary angiogram. Which
information would the nurse anticipate might lead to rescheduling the test?
a. The patient's most recent A1C was 6.5%.
b. The patient's blood glucose is 128 mg/dL.
c. The patient took the prescribed metformin today.
d. The patient took the prescribed captopril this morning. - ANS ✔✔c. The patient took the prescribed
metformin today.
To avoid lactic acidosis, metformin should be discontinued a day or 2 before the coronary angiogram and
should not be used for 48 hours after IV contrast media are administered. The other patient data will
also be reported but do not indicate any need to reschedule the procedure.
Which patient action indicates a good understanding of the nurse's teaching about the use of an insulin
pump?
a. The patient programs the pump for an insulin bolus after eating.
b. The patient changes the location of the insertion site every week.
c. The patient takes the pump off at bedtime and starts it again each morning.
d. The patient plans a diet with more calories than usual when using the pump. - ANS ✔✔a. The patient
programs the pump for an insulin bolus after eating.
In addition to the basal rate of insulin infusion, the patient will adjust the pump to administer a bolus
after each meal, with the dosage depending on the oral intake. The insertion site should be changed
every 2 or 3 days. There is more flexibility in diet and exercise when an insulin pump is used, but it does
not provide for consuming a higher calorie diet. The pump will deliver a basal insulin rate 24 hours a day.
When a patient who takes metformin (Glucophage) to manage type 2 diabetes develops an allergic rash
from an unknown cause, the health care provider prescribes prednisone. The nurse will anticipate that
the patient may
a. need a diet higher in calories while receiving prednisone.
b. develop acute hypoglycemia while taking the prednisone.
c. require administration of insulin while taking prednisone.
d. have rashes caused by metformin-prednisone interactions. - ANS ✔✔c. require administration of
insulin while taking prednisone.
Glucose levels increase when patients are taking corticosteroids, and insulin may be required to control
blood glucose. Hypoglycemia is not a side effect of prednisone. Rashes are not an adverse effect caused
by taking metformin and prednisone simultaneously. The patient may have an increased appetite when
taking prednisone but will not need a diet that is higher in calories.
The nurse is preparing to teach a 43-yr-old man who is newly diagnosed with type 2 diabetes about
home management of the disease. Which action should the nurse take first?
a. Ask the patient's family to participate in the diabetes education program.
