The nurse is planning care for a client with type 1 diabetes mellitus. When planning administration for rapid-acting insulin Lispro, the nurse knows to administer it during which timeframe based on the onset of action?

Lispro lasts 24 hours and does not have to be timed with meals.

60 minutes before meals.

15-30 minutes before meals.

2-6 hours before meals.

Answer and Explanation

The Correct Answer is C

A. This statement is incorrect. Lispro is a rapid-acting insulin, and its duration of action is much shorter than 24 hours. It is typically effective for about 3-5 hours.
B. Administering Lispro 60 minutes before meals would be too early, as it peaks in about 1-2 hours after injection and works best when given closer to meal times.
C. Lispro should be administered 15-30 minutes before meals to match the onset of action, which begins within 15 minutes of injection. This timing allows the insulin to be active when blood glucose rises after eating.
D. Lispro does not require administration 2-6 hours before meals, as this would not align with its rapid onset of action.

Correct Answer is A

Explanation

A. 50% Dextrose in Water (D50W) IV push is the most appropriate intervention for a client with a blood glucose level of 30 mg/dL, indicating severe hypoglycemia. The rapid administration of D50W will quickly raise the blood glucose level and help restore consciousness.
B. Insulin Regular IV push would lower the blood glucose level, which is not appropriate in this situation where the client is hypoglycemic.
C. 0.9% sodium chloride infusion is a general fluid replacement solution, but it will not address the client's low blood glucose level.
D. 5% Dextrose continuous IV infusion is typically used for maintenance, but it would not act as quickly as D50W to correct severe hypoglycemia in an unconscious patient.

A. Hypertension and headache B. Tachycardia and tachypnea C. Depressed deep tendon reflexes D. Positive Trousseau's sign

Correct Answer is C

Explanation

A. Hypertension and headache are not typical signs of hypermagnesemia. These symptoms are more commonly associated with conditions like hypertension or intracranial pressure.
B. Tachycardia and tachypnea are not characteristic of hypermagnesemia. In fact, hypermagnesemia typically causes bradycardia and hypoventilation due to the depressant effect of magnesium on the cardiovascular and respiratory systems.
C. Depressed deep tendon reflexes are a classic sign of hypermagnesemia. Magnesium sulfate acts as a central nervous system depressant, and elevated magnesium levels can impair neuromuscular function, leading to reduced reflexes.
D. Positive Trousseau's sign is indicative of hypocalcemia, not hypermagnesemia. It is a sign of low calcium levels, where a blood pressure cuff inflated above systolic pressure for 3 minutes causes muscle spasms in the hand and forearm.
