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: This is not the first priority because it is not a life-threatening condition. The male adolescent may have gastroenteritis or food poisoning, which can cause dehydration and electrolyte imbalance. The nurse should monitor his vital signs and fluid intake, but he can wait for further assessment.
Choice B Reason: This is the first priority because it is a potential surgical emergency. The female client may have appendicitis, which can cause peritonitis and sepsis if left untreated. The nurse should assess her pain level, vital signs, and abdominal signs, and prepare her for diagnostic tests and possible surgery.
Choice C Reason: This is not the first priority because it is a chronic condition that does not require immediate intervention. The elderly client may have intermittent claudication, which is a symptom of peripheral arterial disease. The nurse should educate him on leg care and exercise, but he can wait for further assessment.
Choice D Reason: This is not the first priority because it is a common condition that can be treated with antibiotics. The child may have a bacterial infection, such as bronchitis or pneumonia, which can cause productive cough and fever. The nurse should auscultate his lungs and check his temperature, but he can wait for further assessment.
Correct Answer is B
Explanation
A) This client has a mild fever, which may indicate an infection or inflammation. This is a potential complication of enteral feedings, but it is not the most urgent situation. The nurse should monitor the client's vital signs, assess the feeding tube site, and notify the provider if the fever persists or worsens.
B) This client has signs of uremic encephalopathy, which is a life-threatening condition caused by the accumulation of toxins in the brain due to impaired renal function. The nurse should intervene immediately to prevent further
neurological damage and possible coma or death. The nurse should assess the client's level of consciousness, check the blood pressure and urine output, and prepare to administer dialysis or other treatments as ordered by the provider.
C) This client has heat stroke, which is a serious condition that can lead to dehydration, electrolyte imbalance, and organ damage. However, the client is receiving a normal saline IV fluid bolus, which is an appropriate intervention to restore fluid volume and correct sodium levels. The nurse should continue to monitor the client's vital signs, skin
temperature, and urine output, and watch for signs of fluid overload or cerebral edema.
D) This client has hyperemesis gravidarum, which is a severe form of nausea and vomiting during pregnancy that can lead to dehydration, malnutrition, and electrolyte imbalance. However, the client is receiving an infusion of Ringer's Lactate, which is an isotonic solution that can replenish fluid and electrolyte losses. The nurse should continue to monitor the client's vital signs, weight, and intake and output, and administer antiemetics or other medications as ordered by the provider.
