A nurse is preparing to administer lidocaine via continuous IV infusion at 4 mg/min. Available is lidocaine 2 g dextrose 5% in water 500 mL. The nurse should set the IV pump to deliver how many mL/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 ["60"]

Step 1: Determine the Lidocaine Concentration

The solution contains 2 grams (2000 mg) of lidocaine in 500 mL.
To find the amount of lidocaine per mL:
2000 mg ÷ 500 mL = 4 mg/mL

Step 2: Calculate the Total Dose per Hour

The prescribed infusion rate is 4 mg per minute.
In 1 hour (60 minutes), the total dose is:
4 mg/min × 60 min = 240 mg/hr

Step 3: Determine the Infusion Rate in mL/hr

Since each mL contains 4 mg of lidocaine:
240 mg ÷ 4 mg/mL = 60 mL/hr

The nurse should set the IV pump to 60 mL/hr for the continuous IV infusion of lidocaine at a rate of 4 mg/min.

Correct Answer is A

Explanation

Choice A Reason:
Apply the patch to a hairless area of the skin is correct. Nitroglycerin patches should be applied to a clean, hairless area of the skin to ensure proper absorption of the medication. Hair can interfere with the patch's adherence and the absorption of nitroglycerin into the bloodstream. The site chosen should be rotated to prevent skin irritation or tolerance development. Commonly used areas include the chest, upper arms, or torso, but it's important to follow specific instructions provided by the healthcare provider.
Choice B Reason:
Apply a 4x4 dressing over the patch is incorrect. Covering the nitroglycerin patch with a dressing may interfere with its absorption and effectiveness. These patches are designed to be applied directly to the skin without covering.
Choice C Reason:
Apply the patch to the same site every 24 hr is incorrect. Repeatedly applying the patch to the same site increases the risk of skin irritation or tolerance to the medication. It's crucial to rotate patch sites to avoid these issues.
Choice D Reason:
Apply the patch to a bony prominence on the chest is incorrect. Nitroglycerin patches should not be placed on bony prominences because these areas can be uncomfortable and may not provide optimal absorption. Instead, they are typically applied to relatively flat, hairless areas of the skin.

A. Oral B. Intravenous C. Inhalation D. Transdermal

Correct Answer is B

Explanation

Choice A Reason:
Oral is incorrect. Epoetin alfa is not typically administered orally because it would be broken down by digestive enzymes and not absorbed effectively from the gastrointestinal tract.
Choice B Reason:
Intravenous is correct. Epoetin alfa is a medication used to stimulate red blood cell production and is commonly administered intravenously. This route allows for rapid and efficient absorption of the medication into the bloodstream, enabling it to exert its effects effectively.
Choice C Reason:
Inhalation is incorrect. Inhalation is not a route used for epoetin alfa. This medication is intended for systemic effects rather than local effects in the respiratory system.
Choice D Reason:
Transdermal is incorrect. Transdermal administration involves absorption through the skin and is not suitable for epoetin alfa, which needs rapid and direct access to the bloodstream for its action on red blood cell production.
