The nurse is preparing a medication for a patient and observes the date of expiration on the vial occurred 2 months ago.
Which of the following actions should the nurse take?

Step 1: Convert All Fluid Intake to Milliliters (mL)

To accurately record the patient's fluid intake, first, convert each fluid measurement to milliliters:

• 1 cup of coffee = 240 mL
• 4 oz of orange juice = 118.3 mL
• 3 oz of water = 88.7 mL
• 1 cup of flavored gelatin = 236.6 mL
• 1 cup of tea = 240 mL
• 5 oz of broth = 147.9 mL
• 3 oz of water (another serving) = 88.7 mL

Step 2: Calculate Total Fluid Intake

Add all the converted fluid amounts together:

• Total fluid intake = 240 mL (coffee) + 118.3 mL (orange juice) + 88.7 mL (water) + 236.6 mL (gelatin) + 240 mL (tea) + 147.9 mL (broth) + 88.7 mL (water) = 1,160.2 mL

Step 3: Round to the Nearest Whole Number

Round the total to the nearest whole number:

• Rounded total = 1,160 mL

The nurse should record 1,160 mL on the patient’s chart.

Choice A rationale

Lidocaine does not primarily serve to relieve pain when administered intravenously. It is primarily used as an antiarrhythmic agent.

Choice B rationale

Lidocaine does not slow intestinal motility. This is not one of its primary actions.

Choice C rationale

Lidocaine does not dissolve blood clots. It is not an anticoagulant.

Choice D rationale

Lidocaine prevents dysrhythmias. It is an antidysrhythmic medication that delays the conduction in the heart and reduces the automaticity of heart tissue.
