The healthcare provider prescribes and IV solution of regular insulin (Humulin-R) 100 units in 250 ml of 0.45% saline to infuse at 12 units/hour. The nurse should program the infusion pump to deliver how many ml/hour?
The Correct Answer is ["30"]
First, we need to find the concentration of insulin in the IV solution, which is the ratio of insulin units to saline volume. To do this, we use the given information that the IV solution contains 100 units in 250 ml. So, we divide 100 by 250 and get 0.4 units/ml.
Next, we need to calculate the infusion rate in ml/hour for the ordered dose of 12 units/hour. To do this, we use the ratio of insulin units to saline volume, which is 0.4 units/ml. So, we set up a proportion as follows:
0.4/1=12/x
To solve for x, we cross-multiply and get 0.4 x = 12. Then, we divide both sides by 0.4 and get x = 30. So, the infusion rate is 30 ml/hour.
Therefore, the nurse should program the infusion pump to deliver 30 ml/hour..

Correct Answer is ["B","D","E"]
Explanation
Choice A reason: This is incorrect because providing a diet low in phosphorus is not indicated for a client with cirrhosis of the liver. Phosphorus restriction is more relevant for clients with renal failure, not liver failure.
Choice B reason: This is correct because noting signs of swelling and edema is an essential intervention for a client with cirrhosis of the liver. Swelling and edema are signs of fluid retention and portal hypertension, which are common complications of liver disease.
Choice C reason: This is incorrect because increasing oral fluid intake to 1,500 mL daily is not advisable for a client with cirrhosis of the liver. Fluid restriction may be necessary to prevent fluid overload and ascites, which are common complications of liver disease.
Choice D reason: This is correct because monitoring abdominal girth is an important intervention for a client with cirrhosis of the liver. Abdominal girth measurement can indicate the presence and severity of ascites, which is a common complication of liver disease.
Choice E reason: This is correct because reporting serum albumin and globulin levels is a vital intervention for a client with cirrhosis of the liver. Serum albumin and globulin levels can reflect the liver's synthetic function and indicate the extent of liver damage.
Correct Answer is D
Explanation
Choice A reason: Securing chest tube to the stretcher for transport is not the most important action for the nurse to take. Chest tube is a device that drains air or fluid from the pleural space or mediastinum after surgery or trauma. Securing chest tube to the stretcher can prevent accidental dislodgement or kinking of the tube during transport, but it is not as crucial as maintaining proper drainage.
Choice B reason: Administering PRN pain medication prior to transport is not the most important action for the nurse to take. Pain medication is a drug that relieves pain by blocking pain signals or reducing inflammation. Administering pain medication prior to transport can improve comfort and reduce anxiety for the client, but it is not as urgent as preventing complications.
Choice C reason: Marking the amount of chest drainage on the container is not the most important action for the nurse to take. Chest drainage is the fluid or air that collects in the chest tube container after being drained from the pleural space or mediastinum. Marking the amount of chest drainage on the container can help monitor fluid balance and detect excessive bleeding or leakage, but it is not as vital as ensuring proper drainage.
