A) Administer insulin
B) Give 15 g of fast-acting carbohydrate
C) Administer glucagon IM
D) Call the provider
Answer: B – The "rule of 15" for conscious hypoglycemia: give 15 g of fast-
acting carbohydrate (4 oz juice, 3-4 glucose tablets, 1 tbsp honey or sugar).
Recheck blood glucose in 15 minutes.
2. A client with hyperthyroidism is prescribed propylthiouracil (PTU). The
nurse should monitor for which adverse effect?
A) Agranulocytosis
B) Hyperglycemia
C) Weight gain
D) Bradycardia
Answer: A – PTU and methimazole can cause agranulocytosis (fever, sore
throat, infection). CBC should be monitored. Instruct the client to report
signs of infection immediately.
3. A client with diabetes mellitus has an HbA1c of 9.2%. The nurse
interprets this as:
A) Excellent control
B) Poor control over the past 2-3 months
,C) Acute hyperglycemia
D) Lab error

is <7%. 9.2% indicates poor control requiring intervention.

intervention is most appropriate?
A) Apply artificial tears
B) Elevate the head of the bed
C) Tape the eyelids closed at night

nursing intervention?
A) Airway and breathing
B) Administering levothyroxine IV
C) Warming the client gradually
D) Administering IV fluids

A) Peaks in 4-6 hours
B) Has no pronounced peak
C) Should be mixed with regular insulin
