The nurse must administer 1600 mL of total parenteral nutrition (TPN) over 24 hours. The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest tenth, do not use trailing zeros, use a leading zero if it applies)

Answer and Explanation

The Correct Answer is ["66.7"]

Step 1: Determine the total volume to be administered. Total volume = 1600 mL

Step 2: Determine the total time in hours. Total time = 24 hours

Step 3: Calculate the rate in mL/hr. Rate = Total volume ÷ Total time Rate = 1600 mL ÷ 24 hours Rate = 66.6667 mL/hr

Step 4: Round to the nearest tenth. Rounded rate = 66.7 mL/hr

The nurse should set the IV pump to deliver 66.7 mL/hr.

Correct Answer is C

Explanation

Choice A reason:

Reducing rebreathing of exhaled air is not a primary characteristic of a Venturi mask. This feature is more associated with non-rebreather masks, which have a one-way valve to prevent exhaled air from being inhaled again.

Choice B reason:

Delivering high percentages of oxygen at flow rates of 10 to 15 L/min is not specific to Venturi masks. Non-rebreather masks are typically used for high oxygen flow rates. Venturi masks are designed to deliver precise oxygen concentrations at lower flow rates.

Choice C reason:

Providing a precise amount of oxygen is the key characteristic of a Venturi mask. Venturi masks are equipped with color-coded adapters that allow for the delivery of specific oxygen concentrations, regardless of the patient’s breathing pattern.

Choice D reason:

Working independently of client breathing factors and flow of oxygen is not entirely accurate. While Venturi masks do provide a consistent oxygen concentration, they still depend on the flow of oxygen set by the healthcare provider.

A. Place on cardiac monitoring. B. Monitor breath sounds every 4 hours. C. Restrict fluids to 500 mL per day. D. Implement safety precautions.

Correct Answer is C

Explanation

Choice A reason: Placing the client on cardiac monitoring is important, especially if there are signs of cardiac involvement or if the client is at risk for arrhythmias. However, it is not the primary intervention for hypernatremia. Hypernatremia primarily affects fluid balance and neurological status.

Choice B reason: Monitoring breath sounds every 4 hours is a good practice, particularly if there is a risk of fluid overload or respiratory complications. However, it does not directly address the issue of hypernatremia. The primary concern with hypernatremia is managing fluid balance and preventing further increases in serum sodium levels.

Choice C reason: Restricting fluids to 500 mL per day is a critical intervention for managing hypernatremia. Hypernatremia often results from a deficit in free water, leading to an elevated serum sodium level. Fluid restriction helps to prevent further increases in sodium concentration and assists in gradually correcting the imbalance. This intervention directly addresses the underlying issue of hypernatremia and helps to stabilize the client’s condition.

Choice D reason: Implementing safety precautions is important, especially if the client is experiencing neurological symptoms such as confusion or agitation. While safety precautions are necessary, they are not the primary intervention for correcting hypernatremia. The focus should be on managing fluid balance and serum sodium levels.
