Which of the following medications does the nurse anticipate being ordered for a client admitted with the following tachycardic rhythm and complaints of palpitations and dizziness?
Adenosine 6mg iVP fast followed by a 10mL saline flush.
Atenolol 25mg PO.
Metoprolol 25mg IVP.
Atropine IVP fast followed by a 10ml saline flush.
The Correct Answer is C
Choice A rationale: Adenosine is primarily used to treat supraventricular tachycardia, not typically used for tachycardic rhythm with palpitations and dizziness5.
Choice B rationale: Atenolol is a beta-blocker that can be used to treat tachycardia, but it is not typically the first choice for acute symptoms5.
Choice C rationale: Metoprolol is a beta-blocker that is often used to treat tachycardia and can help alleviate symptoms such as palpitations and dizziness5.
Choice D rationale: Atropine is typically used to treat bradycardia, not tachycardia5.
So, the correct answer is C, after analysing all choices.

Correct Answer is ["83"]
Explanation
Step 1 is to use the formula for calculating the IV infusion rate: Infusion Rate (mL/hour) = Volume to be Infused (mL) ÷ Time for Infusion (hours)5.
So, Infusion Rate = 1000 mL ÷ 12 hours = 83.33 mL/hr.
Rounding to the nearest whole number gives 83 mL/hr.
So, the correct answer is 83 mL/hr, after calculating.
