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.
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 D
Explanation
A. Ensuring an incentive spirometer is available is important for postoperative care to prevent atelectasis, but it is not the priority immediately before surgery.
B. Preoperative teaching is valuable but should ideally be completed earlier in the care process. Last-minute teaching may overwhelm the patient or delay critical interventions.
C. Reporting allergies is essential, but if the allergy to sardines does not pertain to the current surgical plan or medications, it is not the immediate priority in this situation.
D. Administering the preoperative intravenous antibiotic is the top priority because it helps reduce the risk of surgical site infections. Timing of preoperative antibiotics is critical to their effectiveness.
Correct Answer is ["A","D","E"]
Explanation
A. Respiratory depression is a common and serious side effect of opioid medications. The patient's respiratory rate is 11 breaths per minute, which is on the low end of normal and could be further depressed by additional opioid administration, increasing the risk of respiratory compromise.
B. Tachycardia is not a typical side effect of opioids. The patient’s heart rate is 72 beats per minute, which is within normal limits, and there is no indication of tachycardia.
C. Urinary frequency is unlikely to be caused by opioids. In fact, opioids can lead to urinary retention, not frequency, and the patient's urinary output is already low (480 mL in 12 hours), suggesting potential urinary retention.
D. Constipation is a common side effect of opioid use. The patient has not had a bowel movement in three days, and absent bowel sounds suggest the possibility of opioid-induced constipation.
E. Hypotension is a known side effect of opioids. The patient’s blood pressure is 90/54, which is on the low side, indicating that further opioid administration could exacerbate hypotension.
