A nurse is preparing to administer 0.45% sodium chloride (NaCl) 1000 mL IV to infuse over 8 hr. The nurse should set the IV pump to deliver how many mL/hr?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero)
Answer and Explanation

The Correct Answer is ["125"]

  1. Identify the given values:

    • Total volume = 1000 mL
    • Total infusion time = 8 hours

  2. Use the formula for infusion rate:

    Infusion Rate (mL/hr) = Total Volume (mL) ÷ Total Time (hours)

    Infusion Rate = 1000 mL ÷ 8 hours

    Infusion Rate = 125 mL/hr

Final Answer:

The nurse should set the IV pump to 125 mL/hr for the 0.45% NaCl solution

Correct Answer is ["125"]

Explanation

This is a question that tests the nurse's ability to calculate the infusion rate of an IV solution. To answer this question, the nurse needs to use the following formula: Infusion rate (mL/hr) = (Volume of solution (mL) x Dose ordered (mEq/hr)) / Dose available (mEq)

Plugging in the given values, we get:

Infusion rate (mL/hr) = (500 mL x 10 mEq/hr) / 40 mEq Simplifying, we get:

Infusion rate (mL/hr) = 125 mL/hr

Therefore, the nurse should set the IV pump to deliver 125 mL/hr.

Correct Answer is B

Explanation

A. Severe vomiting can lead to a loss of gastric acid, resulting in metabolic alkalosis and not acidosis.
B. A client who is experiencing severe nausea and vomiting may lose gastric acid through vomitus and develop metabolic alkalosis, which is a condition characterized by a high pH (greater than 7.45) and a high bicarbonate (greater than 26 mEq/L). Metabolic alkalosis can cause confusion, tremors, tetany, and hypokalemia.
C. Respiratory alkalosis is not typically associated with vomiting; it is more often seen in conditions with hyperventilation.
D. Respiratory acidosis is not the primary acid-base imbalance associated with vomiting; it is more commonly associated with conditions affecting lung function.
