Q

A nurse is providing a bedtime snack for his patient. This is based on the knowledge that intermediate acting insulins are effective for an approximate duration of…

A) 6-8 hours
B) 10-14 hours
C) 14-18 hours
D) 24-28 hours

A

C) 14-18 hours

B/C Intermediate acting insulins (NPH) include Humulin & Novolin. They have an onset of 2-4 hours, peak of 4-12, and duration of 14-18.

31
Q

A nurse went into a patient’s room to do routine vital signs and found that the patient’s bedtime snack was not eaten. This should alert the nurse to check and assess for

A) Elevated serum bicarbonate & decreased blood pH
B) Signs of hypoglycemia earlier than expected
C) Symptoms of hyperglycemia during the peak time of NPH insulin
C) Sugar in the urine

A

B) Signs of hypoglycemia earlier than expected

B/C a bedtime snack can prevent blood sugar levels from dropping very low during the night

32
Q

The client is taking NPH insulin daily every morning. The nurse instructs the client that the most likely time for a hypoglycemia reaction to occur is

A) 2-4 hours after admin
B) 6-14 hours after admin
C) 16-18 hours after admin
D) 18-24 hours after admin

A

B) 6-14 hours after admin

B/C the peak time of insulin is the time it is working the hardest. NPH insulin is an intermediate acting insulin that has an onset of 2-4 hours, peaks at 4-12, and effective for 14-18 hours.

33
Q

A client w/ DKA is being treated in the ER. Which finding would a nurse expect to note as confirming this diagnosis?

A) Elevated blood glucose level and low plasma bicarbonate
B) Decreased urine output
C) Increased RR & pH
D) Comatose state

A

A) Elevated blood glucose level & low plasma bicarbonate

B/C in DKA blood glucose will be >250 and plasma bicarb will be <15mEq/L, & ketones will be present in blood and urine

34
Q

A client with DM demonstrates acute anxiety when first admitted for the treatment of hyperglycemia. The MOST appropriate intervention to decrease the patient’s anxiety would be to

A) Administer a sedative
B) Make sure the client knows all the correct medical terms to understand what is happening

A) Administer regular insulin IV
B) Administer 5% dextrose IV
C) Correct the acidosis
D) Apply an ECG monitor

A

A) Administer regular insulin IV

B/C lack of insulin causes DKA (Type 1)

36
Q

40
Q

A 44-year-old woman with type 1 diabetes comes to the emergency department due to abdominal pain accompanied by nausea and vomiting. The patient had a history of chronic back pain due to a motor accident 20 years ago. Her situation renders her unable to work and pay for the increasing price of insulin, which has doubled during the last five years. The patient doesn’t have medical coverage or insurance; therefore, she rations her insulin intake, making her unable to follow her prescribed therapeutic regimen for her diabetes. Because of her situation, the client is at high risk of developing diabetic ketoacidosis. As her nurse, which of the following symptoms would you anticipate the client to exhibit? Select all that apply.

A) Fruity odor breath
B) Deep & labored respirations
C) Blurred vision
D) Increased urination
E) Increased thirst
