The doctor orders dextrose 5% in water 1,000 mL to be infused over 8 hours. The IV tubing delivers 15 drops per milliliter. The nurse in charge should run the IV infusion at a rate of:
NOTE: Enter ONLY THE NUMBER DO NOT enter the unit of measurement
The Correct Answer is ["31"]
Let’s calculate the IV infusion rate step by step.
Step 1: Determine the total volume to be infused.
The total volume ordered is 1,000 mL.
Step 2: Determine the total time for the infusion.
The total time is 8 hours.
Step 3: Calculate the infusion rate in mL per hour.
Total volume (1,000 mL) ÷ Total time (8 hours) = 125 mL per hour.
Result: 125
Step 4: Determine the drop factor.
The IV tubing delivers 15 drops per milliliter.
Step 5: Calculate the infusion rate in drops per minute.
Infusion rate (125 mL per hour) × Drop factor (15 drops per mL) = 1,875 drops per hour.
Result: 1,875
Step 6: Convert the infusion rate to drops per minute.
Total drops per hour (1,875 drops) ÷ 60 minutes = 31.25 drops per minute.
Result: 31.25
Step 7: Round the result to the nearest whole number if necessary.
31.25 rounded to the nearest whole number is 31.
The nurse should run the IV infusion at a rate of 31 drops per minute.

Correct Answer is ["C","D","E"]
Explanation
Choice A reason: Stretch marks, also known as striae, are not specific to ascites. They can occur due to rapid weight gain or loss, pregnancy, or other conditions that cause the skin to stretch. While they may be present in individuals with ascites due to rapid abdominal expansion, they are not a primary clinical manifestation of ascites.
Choice B reason: Foul-smelling breath, or halitosis, is not a typical symptom of ascites. It can be associated with various conditions, including poor oral hygiene, gastrointestinal disorders, or liver disease, but it is not a direct indicator of ascites.
Choice C reason: Increased abdominal girth is a primary clinical manifestation of ascites. Ascites is characterized by the accumulation of fluid in the peritoneal cavity, leading to noticeable abdominal distension. This symptom is often accompanied by a feeling of fullness or bloating.
Choice D reason: Visible distended veins, particularly around the abdomen, can be a sign of ascites. This occurs due to increased pressure in the abdominal veins as a result of fluid accumulation. The veins become more prominent and visible under the skin.
Choice E reason: Rapid weight gain is another key indicator of ascites. The accumulation of fluid in the abdomen leads to a significant increase in body weight over a short period. This rapid weight gain is often one of the first signs that prompts further investigation for ascites.
Correct Answer is C
Explanation
Choice A Reason:
Administering levetiracetam intravenously is not the first intervention. While levetiracetam is an antiepileptic drug used to control seizures, it is not the first-line treatment for an ongoing seizure, especially one lasting as long as 15 minutes. The priority in this situation is to stop the seizure activity immediately to prevent further complications, such as neuronal damage or status epilepticus. Levetiracetam may be used later for maintenance therapy, but it is not the initial emergency intervention.
Choice B Reason:
Obtaining a STAT electroencephalogram (EEG) is important for diagnosing and understanding the type of seizure activity, but it is not the first intervention. The immediate priority is to stop the seizure. An EEG can be performed after the seizure has been controlled to assess brain activity and guide further treatment. Delaying the administration of an anticonvulsant to perform an EEG could result in prolonged seizure activity and increased risk of complications.
Choice C Reason:
Administering lorazepam intravenously is the most appropriate first intervention. Lorazepam is a benzodiazepine that acts quickly to stop seizure activity. It is the drug of choice for treating status epilepticus and prolonged seizures because of its rapid onset and effectiveness. Administering lorazepam helps to quickly terminate the seizure, reducing the risk of complications and stabilizing the patient for further evaluation and treatment.
Choice D Reason:
Obtaining a STAT 12-lead electrocardiogram (ECG) is not the first intervention. While an ECG can provide valuable information about the patient’s cardiac status, it does not address the immediate need to stop the seizure. The priority is to administer an anticonvulsant to terminate the seizure. Once the seizure is controlled, an ECG can be performed to assess any potential cardiac issues, especially if the patient has a history of cardiac problems or if the seizure was triggered by a cardiac event.
