A nurse is preparing to administer pantoprazole 7 mg PO to an infant. The amount available is pantoprazole 2 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["3.5"]
Identify the given information:
Dose of pantoprazole: 7 mg
Concentration of pantoprazole: 2 mg/mL
Calculate the volume of pantoprazole to be administered:
Volume = Dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume = 7 mg / 2 mg/mL
Calculate the result:
Volume = 3.5 mL

Correct Answer is ["300"]
Explanation
Identify the given information:
Volume of lactated Ringer's solution: 150 mL
Infusion time: 30 minutes
Convert the infusion time to hours:
30 minutes = 30/60 hours = 0.5 hours
Calculate the infusion rate in mL/hr:
Infusion rate = Volume / Time
Substitute the values:
Infusion rate = 150 mL / 0.5 hr
Calculate the result:
Infusion rate = 300 mL/hr
Correct Answer is D
Explanation
A) Give the client two troches in the morning and two troches in the evening:
While this option describes the correct number of doses, it does not address the critical aspect of how the troche should be administered. The troche must dissolve in the mouth, not be swallowed immediately, and the focus should be on how the medication is used rather than the total number of doses per day. The timing of doses (morning and evening) is correct, but the method of administration needs further clarification.
B) Tell the client to keep the troche under the tongue for 5 min before swallowing it:
Troches should not be kept under the tongue or swallowed after a short duration. The medication is intended to dissolve in the mouth, where it can act locally. Keeping it under the tongue or swallowing it too soon would reduce its efficacy in treating fungal infections of the mouth or throat. Therefore, this instruction is incorrect.
C) Instruct the client to swallow the troche with 240 mL (8 oz) water:
Swallowing the troche with water is not appropriate because it prevents the medication from dissolving properly in the mouth. Nystatin troches are designed to dissolve slowly in the mouth, releasing medication to treat the infection. Swallowing it immediately would bypass the intended mechanism of action. Therefore, this instruction is incorrect.
D) Withhold oral intake until the troche dissolves in the client's mouth:
This is the correct instruction. Nystatin troches need to dissolve slowly in the mouth to ensure the medication can work locally on the fungal infection. The client should not swallow the troche immediately and should wait until it has fully dissolved, which can take several minutes. This allows for the proper therapeutic effect in treating infections of the mouth or throat.
