The bag contains 200 mg of medication per 100 mL of solution. If the medication will infuse at the rate of 10 mg/min, how long will this infusion take to completely administer to the client?

A client is prescribed 1 g potassium phosphate IV to be infused continuously over 6 hr. Available is 1 g potassium phosphate in 250 mL dextrose 5% water. The nurse should set the IV pump to run at how many mL/hr? (round to nearest whole number)

Match the following situations with how you would adjust the sweep speed to display them properly on your spectral tracing. The patient has bradycardia Choose.increase/ decrease The patient has an arrhythmia that you would like to demonstrate Choose..increase/ decrease You want to demonstrate less beats on your tracing Choose.increase/ decrease You want to demonstrate more beats on your tracing Choose...increase/ decrease The patient has tachycardia Choose...increase/ decrease

in an ECG recording, the RR interval is 500 msecs. what is the heart rate?

If a person’s heart rate is 72 beats per minute, determine the number of QRS complexes that would have appeared on an ECG during the first 30 seconds.

What is wrong with this statement: “In this lab we are measuring the subjects ECG” . Explain

What is the Atrial-Heart Rate in the strip?

An IV is set to run at 94 gtt/min. What would the 15 second drip rate be? (Record answer as a whole number. Do not use a trailing zero.)
