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 B

Explanation

A. Decreased urine output is not directly associated with elevated potassium levels. It is more commonly linked to renal failure or dehydration.
B. Hyperkalemia (high potassium levels) can lead to ascending muscle paralysis due to its effects on the neuromuscular system. Potassium is critical for proper muscle function, and elevated levels can disrupt the electrical impulses needed for muscle contraction, potentially causing paralysis.
C. Hypoglycemia is unrelated to elevated potassium levels. It is more often associated with insulin use, inadequate food intake, or certain medical conditions.
D. Ascites is fluid accumulation in the abdomen, usually caused by liver disease or heart failure, and is not a direct complication of hyperkalemia.

A. Urine output of 32 mL/hour. B. Confusion and disorientation. C. Blood pressure of 106/82. D. 2+ pedal edema bilaterally.

Correct Answer is B

Explanation

A. A urine output of 32 mL/hour is slightly below the normal threshold (30 mL/hour) but does not indicate an immediate threat requiring intervention.
B. Confusion and disorientation are signs of severe hyponatremia, which can lead to cerebral edema and life-threatening complications such as seizures or coma. This finding requires immediate intervention to prevent worsening neurological impairment.
C. A blood pressure of 106/82 is within an acceptable range and does not indicate a critical issue in this context.
D. Bilateral 2+ pedal edema is not uncommon in elderly clients and does not directly indicate a severe complication of hyponatremia requiring immediate action.
