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?
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 B
Explanation
Choice A reason: This choice is incorrect because there is no need to recheck the heart rate in one hour before giving the digoxin. The client's apical heart rate is within the normal range (60 to 100 beats per minute) and does not indicate bradycardia (slow heart rate), which is a sign of digoxin toxicity. The nurse should check the apical heart rate for one full minute before giving the digoxin and withhold the dose if the heart rate is below 60 beats per minute.
Choice B reason: This choice is correct because the client's digoxin level is within the therapeutic range (0.5 to 2.0 ng/mL) and does not indicate digoxin toxicity or underdosing. The client's vital signs and labs are also stable and do not indicate any adverse effects of digoxin. Digoxin is a cardiac glycoside that improves the contractility and efficiency of the heart and helps to control the heart rate and rhythm in clients with heart failure. The nurse should give the digoxin as ordered and monitor the client's response and digoxin level.
Choice C reason: This choice is incorrect because there is no indication for a chest x-ray for this client. A chest x-ray is a diagnostic test that can show the size and shape of the heart and lungs and detect any abnormalities, such as fluid accumulation, infection, or tumors. The client's symptoms and labs do not suggest any pulmonary complications or worsening of heart failure that would require a chest x-ray. The nurse should follow the provider's orders and protocols for chest x-ray indications.
Choice D reason: This choice is incorrect because there is no reason to hold the digoxin and call the MD for this client. The client's digoxin level is not too high or too low and does not require dose adjustment or discontinuation. The client's vital signs and labs are also normal and do not indicate any signs of digoxin toxicity or adverse effects. Holding the digoxin could cause the client's heart failure to worsen or cause arrhythmias. The nurse should only hold the digoxin and call the MD if the client has signs of digoxin toxicity, such as nausea, vomiting, visual disturbances, confusion, or bradycardia. .
Correct Answer is ["5"]
Explanation
To calculate the volume of hydrochlorothiazide oral solution that the nurse should administer per dose, we can use the following steps:
Determine the total daily dose:
The total daily dose is 150 mg.
Divide the total daily dose into 3 equally divided doses:
150 mg ÷ 3 = 50 mg per dose
Calculate the volume to be administered per dose:
The available oral solution has a concentration of 50 mg/5 mL.
50 mg ÷ 50 mg/5 mL = 5 mL
Therefore, the nurse should administer 5 mL of hydrochlorothiazide oral solution per dose.
