Question 1 of 5.
The nurse administers a combination of regular insulin and NPH insulin subcutaneously to a client at 0800. At which time should the nurse initially assess the client for hypoglycemia based on the peaks of the medications?
A. 830
B. 1000
C. 1200
D. 1400
Explanation: Regular insulin peaks at 2-4 hours (1000-1200), and NPH peaks at 4-12 hours. Initial hypoglycemia risk is highest around 1000 due to regular insulin's peak effect.
Question 2 of 5.
The nurse is caring for a client with Graves' disease who has exophthalmos. The nurse should recommend that the client
A. prevent eye dryness by applying artificial tears.
B. use scanning techniques to move the head from side to side.
C. take their thyroid hormone as prescribed.
D. sleep flat on your back without any pillows.
Explanation: Exophthalmos in Graves' disease causes protruding eyes, increasing the risk of dryness and irritation. Artificial tears help maintain moisture and protect the eyes. Sleeping flat may worsen eye protrusion, and thyroid hormone management is unrelated to exophthalmos directly.
Question 3 of 5.
The nurse is caring for a client who developed a thyroid storm. The nurse should obtain a prescription for
A. enalapril.
B. calcium gluconate.
C. levothyroxine.
D. propranolol.
Explanation: Thyroid storm is a life-threatening hyperthyroid state. Propranolol, a beta-blocker, reduces heart rate, blood pressure, and other hypermetabolic symptoms. Enalapril is for hypertension, calcium gluconate for hypocalcemia, and levothyroxine worsens hyperthyroidism.
Question 4 of 5.
The nurse is developing a plan of care for a client with hypothyroidism that is not controlled with medication. The nurse should recommend
A. applying lotion after a warm bath.
B. high-fiber snacks.
C. caffeinated beverages to promote energy.
D. physical activities with frequent rest breaks.
E. adding fans to the room to keep it cool.
Explanation: Hypothyroidism causes dry skin, constipation, and fatigue. Lotion hydrates skin, high-fiber snacks aid bowel movements, and rest breaks accommodate low energy. Caffeine may overstimulate, and fans are unhelpful as clients feel cold, not hot.
Question 5 of 5.
The nurse is assessing a client with a myxedema coma. Which of the following would be an expected finding?
A. Glucose 59 mg/dL (3.28 mmol/L) [70-110 mg/d, 4.0-6.0 mmol/L]
B. Sodium 155 mEq/L (mmol/L) [135-145 mEq/L, mmol/L]
C. Serum pH 7.49 [7.35-7.45]
Explanation: Myxedema coma, a severe hypothyroid state, can cause hypoglycemia due to reduced metabolism. Hypernatremia and alkalosis are not typical; hyponatremia and acidosis are more common.
