Order: 200 mL normal saline bolus IV over 15 minutes

On hand: 500 mL normal saline bags

What rate will the nurse set the pump to deliver the fluid?
Answer and Explanation

The Correct Answer is ["800"]

This choice is correct because it is the result of dividing the volume of the bolus (200 mL) by the time of the infusion (15 minutes) and multiplying by 60 minutes per hour. The formula for calculating the rate of the pump is:

Rate = (Volume/Time) x 60

Therefore, the rate of the pump is:

Rate = (200 mL/ 15 min) x 60 = 800 mL/hr

Correct Answer is ["5"]

Explanation

To calculate the amount of megestrol oral suspension that the nurse should administer, we can use the following formula:

Amount to administer (mL) = (Desired dose in mg) / (Amount of drug in 1 mL)

Given:

Desired dose = 200 mg

Amount of drug in 1 mL = 40 mg/mL

Now, let's calculate the amount to administer:

Amount to administer (mL) = 200 mg / 40 mg/mL

Amount to administer (mL) = 5 mL

Rounding to the nearest whole number, the nurse should administer 5 mL of the megestrol oral suspension.

Correct Answer is C

Explanation

Choice A reason: This is incorrect. INR level is a measure of blood clotting time and is not directly affected by digoxin. It is more relevant for patients who are taking anticoagulants, such as warfarin.

Choice B reason: This is incorrect. Temperature is not a priority assessment for a patient receiving digoxin. It may indicate an infection or inflammation, but it is not related to the action or toxicity of digoxin.

Choice C reason: This is correct. Apical heart rate is the priority assessment for a patient receiving digoxin. Digoxin is a cardiac glycoside that increases the force and efficiency of the heart contractions, but also slows down the heart rate. The nurse should monitor the apical pulse for one full minute before administering digoxin and withhold the dose if the pulse is below 60 beats per minute for adults or below the age-specific normal range for children. A low or irregular pulse may indicate digoxin toxicity, which can be life-threatening.

Choice D reason: This is incorrect. Blood pressure is not a priority assessment for a patient receiving digoxin. Digoxin does not have a direct effect on blood pressure, although it may improve the cardiac output and reduce the fluid retention in patients with heart failure. Blood pressure should be monitored regularly, but it is not as critical as the apical heart rate.
