  1. 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 ["125ml\/hour"]

The infusion rate for 0.45% NaCl 1000 mL over 8 hours is calculated as follows:

1000 mL / 8 hr = 125 mL/hr

Correct Answer is C

Explanation

Correct answer: C

A. This action would be appropriate if the potassium level were high, indicating hyperkalemia. However, since the client's potassium level is low, the nurse should administer the KCl as prescribed to address the hypokalemia. If there are any concerns about the rate or method of administration, or if the client shows signs of potassium-related complications, the nurse should then consult the provider.

B.Calling the lab to verify the client's results may seem like a reasonable action, but it's not the most appropriate in this scenario. Serum potassium levels are commonly measured accurately, and the nurse should prioritize clinical judgment based on the current potassium level in conjunction with the client's condition and medication regimen.

C. A serum potassium level of 3.2 mEq/L is below the normal range (3.5-5.0 mEq/L), indicating hypokalemia. Hypokalemia can have serious consequences, including muscle weakness, cardiac arrhythmias, and other complications. Administering potassium chloride (KCl) as prescribed is necessary to correct this deficiency and prevent potential adverse effects associated with low potassium levels.

D.Simply omitting the KCL dose without informing the healthcare provider of the client's low potassium level could lead to a missed opportunity for appropriate intervention. Documenting the omission is essential for accurate record-keeping, but it's crucial to communicate the situation to the provider for further guidance.

Correct Answer is ["56gtt\/min"]

Explanation

To calculate the infusion rate in gtt/min, we need to know the total number of drops (gtt) needed

for the entire infusion and the time it takes to complete the infusion. Given:

  • Ringer's lactate: 500 mL
  • Infusion time: 3 hours
  • Drop factor: 20 gtt/mL

First, let's calculate the total number of drops needed for the entire infusion: Total drops = Volume (mL) × Drop factor (gtt/mL)

Total drops = 500 mL × 20 gtt/mL Total drops = 10,000 gtt

Next, we need to determine the infusion rate in gtt/min. Since the infusion time is given in hours, we need to convert it to minutes:

Infusion time (min) = Infusion time (hours) × 60 min/hour Infusion time (min) = 3 hours × 60 min/hour

Infusion time (min) = 180 min

Now, we can calculate the infusion rate in gtt/min:

Infusion rate (gtt/min) = Total drops / Infusion time (min) Infusion rate (gtt/min) = 10,000 gtt / 180 min

Infusion rate (gtt/min) ≈ 55.6 gtt/min (Rounded off- 56 gtt/min)
