Four clients are scheduled to receive IV infusions, but there are only three intravenous (IV) pumps available. Which prescribed infusion can most safely be administered without an IV infusion pump?
Ceftriaxone in 5% Dextrose in Water prescribed for pneumonia.
Heparin in Normal Saline prescribed for deep vein thrombosis.
Magnesium in Normal Saline prescribed for hypomagnesemia.
Regular insulin in Normal Saline prescribed for ketoacidosis.
The Correct Answer is A
Choice A reason: Ceftriaxone is an antibiotic that can be given by gravity infusion without an IV pump, as long as the nurse monitors the flow rate and adjusts the roller clamp as needed. The dose and duration of ceftriaxone are usually fixed and not affected by minor fluctuations in the infusion rate.
Choice B reason: Heparin is an anticoagulant that requires a precise and constant infusion rate to prevent bleeding or clotting complications. An IV pump is essential to deliver heparin safely and accurately.
Choice C reason: Magnesium is an electrolyte that can cause serious adverse effects such as cardiac arrhythmias,
respiratory depression, and muscle weakness if infused too rapidly or too slowly. An IV pump is necessary to control the infusion rate and prevent magnesium toxicity or deficiency.
Choice D reason: Regular insulin is a hormone that regulates blood glucose levels and requires careful titration based on frequent blood glucose monitoring. An IV pump is required to deliver insulin at a consistent and adjustable rate to avoid hypoglycemia or hyperglycemia.

Correct Answer is B
Explanation
Choice A Reason: The initial administration of the analgesic is not an intervention that the charge nurse should counsel the nurse about. The opioid analgesic was prescribed by the healthcare provider and was appropriate for the postoperative pain management of the client.
Choice B Reason: The decision regarding when to call the healthcare provider is an intervention that the charge nurse should counsel the nurse about. The nurse should have called the healthcare provider as soon as the client's
respiratory rate decreased to 6 breaths/minute, which is a sign of opioid-induced respiratory depression. Waiting for another 30 minutes until the respiratory rate decreased to 4 breaths/minute could have put the client at risk of hypoxia, brain damage, or death.
Choice C Reason: The documentation of the client's respiratory rate is not an intervention that the charge nurse should counsel the nurse about. The nurse documented the client's respiratory rate accurately and timely, which is part of the standard of care and legal responsibility of the nurse.
Choice D Reason: The administration of naloxone via IV is not an intervention that the charge nurse should counsel the nurse about. Naloxone is an opioid antagonist that reverses the effects of opioids and restores normal respiration. Administering naloxone via IV is the fastest and most effective way to treat opioid-induced respiratory depression.
