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 D
Explanation
Choice A Reason: A client with multisystem failure secondary to a motor vehicle collision is not an appropriate assignment for the new graduate nurse. This client has complex and unstable needs that require advanced assessment, intervention, and evaluation skills. The nurse should assign this client to a nurse with 10 years experience, who has more expertise and confidence in managing critically ill clients.
Choice B Reason: A client in end-stage liver failure who is experiencing esophageal bleeding is not an appropriate assignment for the new graduate nurse. This client has a high risk of complications such as hemorrhage, infection, hepatic encephalopathy, and hepatic coma. The nurse should assign this client to a nurse with 5 years experience, who has more knowledge and skill in providing palliative care and managing bleeding disorders.
Choice C Reason: A client with Adult Respiratory Distress Syndrome who is on a ventilator is not an appropriate assignment for the new graduate nurse. This client has a life-threatening condition that requires close monitoring of respiratory status, oxygenation, and hemodynamics. The nurse should assign this client to a nurse with 10 years of experience, who has more competence and proficiency in caring for ventilated clients and interpreting data from invasive devices.
Choice D Reason: A client with chest tubes secondary to a stab wound to the chest is an appropriate assignment for the new graduate nurse. This client has a relatively stable condition that requires routine care of chest tubes, pain management, and wound healing. The nurse should assign this client to the new graduate nurse, who has learned the basic principles and techniques of chest tube management during the refresher course and the internship. The charge nurse should also provide supervision and support to the new graduate nurse as needed.
