A nurse is preparing to administer 12 L of lactated Ringer’s IV to infuse over 24 hr. Half of the fluid is to be administered in the first 8 hr. The nurse should set the IV pump to deliver how many mL/hr during the first 8 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 ["750"]

To calculate the infusion rate for the first 8 hours, we can use the following formula:

Infusion rate (mL/hr) = (Volume to be infused / Time for infusion)

First, we need to find the volume to be infused in the first 8 hours:

Volume for the first 8 hours = Total volume / 2 = 12 L / 2 = 6 L = 6000 mL

Now we can calculate the infusion rate for the first 8 hours:

Infusion rate = 6000 mL / 8 hr = 750 mL/hr

Therefore, the nurse should set the IV pump to deliver 750 mL/hr during the first 8 hours.

Correct Answer is ["0.7"]

Explanation

To calculate the amount of epoetin to administer, we can use the following formula:

Amount to administer (mL) = (Desired dose (units) / Available dose (units/mL))

Plugging in the given values:

Amount to administer (mL) = (7,000 units / 10,000 units/mL)

Now, let's solve for the amount to administer:

Amount to administer (mL) = (7,000 / 10,000) = 0.7 mL

So, the nurse should administer 0.7 mL of epoetin subcutaneously for the management of anemia related to chronic kidney disease.

Correct Answer is A

Explanation

Choice A reason: Atenolol is a beta blocker that lowers blood pressure and heart rate. The nurse should hold atenolol for this client because the client's heart rate is already low (52 beats per minute), and giving atenolol could cause bradycardia (slow heart rate), which can lead to dizziness, fainting, or heart failure. The nurse should notify the provider and monitor the client's vital signs and cardiac rhythm.

Choice B reason: Captopril is an ACE inhibitor that lowers blood pressure and prevents kidney damage. The nurse should not hold captopril for this client because the client's blood pressure is still high (138/90 mmHg), and captopril could help lower it to the target range. The nurse should administer captopril as prescribed and monitor the client's blood pressure and renal function.

Choice C reason: Warfarin is an anticoagulant that prevents blood clots and reduces the risk of stroke. The nurse should not hold warfarin for this client because the client's INR (a measure of blood clotting time) is within the therapeutic range (2.0 to 3.0), and warfarin could help prevent post-operative complications such as deep vein thrombosis or pulmonary embolism. The nurse should administer warfarin as prescribed and monitor the client's INR and bleeding signs.

Choice D reason: Glipizide is not a medication for this client. Glipizide is an oral hypoglycemic agent that lowers blood sugar levels in people with diabetes. This client does not have diabetes and does not need glipizide. The nurse should check the medication order and the client's medical history and clarify any discrepancies with the provider.
