A nurse is preparing to administer potassium chloride 40 mEq in dextrose 5% in 0.9% sodium chloride 1,000 mL IV to infuse over 8 hr. The tubing has a drop factor of 15 gtt/mL.

The nurse should set the IV flow rate to deliver how many gtt/min?
(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 ["31"]

To calculate the IV flow rate in drops per minute (gtt/min), we can use the following steps:

Calculate the total number of minutes for the infusion:

8 hours × 60 minutes/hour = 480 minutes

Determine the total number of drops needed for the infusion:

The total volume to be infused is 1000 mL.

The drop factor is 15 gtt/mL.

1000 mL × 15 gtt/mL = 15000 gtt

Calculate the IV flow rate in drops per minute:

15000 gtt ÷ 480 min ≈ 31 gtt/min

Rounding to the nearest whole number, the nurse should set the IV flow rate to deliver 31 gtt/min.

Correct Answer is B

Explanation

This choice is correct because it is the result of dividing the ordered dose (0.25 mg) by the strength of the tablet (250 mcg or 0.25 mg). The formula for calculating the number of tablets to be given is:

Tablets = Dose/ Strength

Therefore, the number of tablets to be given is:

Tablets = 0.25 mg/250 mcg = 0.25 mg/0.25 mg = 1

A. Excessive urination B. Excessive thirst C. Diaphoresis D. Atrial fibrillation E. Excessive hunger

Correct Answer is ["A","B","E"]

Explanation

Choice A reason: Excessive urination is a sign of hyperglycemia because the body tries to flush out the excess glucose in the blood through the urine. This can also lead to dehydration and electrolyte imbalance.

Choice B reason: Excessive thirst is a sign of hyperglycemia because the body loses fluid and becomes dehydrated due to frequent urination. The thirst mechanism is activated to replenish the fluid loss.

Choice C reason: Diaphoresis is not a sign of hyperglycemia, but rather a sign of hypoglycemia (low blood sugar). Hypoglycemia can cause sweating, shakiness, anxiety, and confusion.

Choice D reason: Atrial fibrillation is not a sign of hyperglycemia, but rather a possible complication of hyperglycemia. Hyperglycemia can damage the blood vessels and the heart, increasing the risk of arrhythmias, such as atrial fibrillation.

Choice E reason: Excessive hunger is a sign of hyperglycemia because the body is unable to use the glucose in the blood for energy. The cells are starved of fuel, and the hunger signal is triggered to stimulate food intake..
