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. "Lie down for 1 hour after administering the medication." B. "Plan to self-administer this medication for the next 6 months." C. "Administer the medication into one nostril once per week." D. "Use a nasal decongestant 15 minutes before the medication if you have a stuffy nose."

Correct Answer is C

Explanation

Choice A Reason:
There's no requirement to lie down for an hour after administering nasal cyanocobalamin.
Choice B Reason:
The duration of treatment might vary depending on the healthcare provider's instructions and the client's response, so stating a specific duration of 6 months may not be accurate.
Choice C Reason:
"Administer the medication into one nostril once per week. “Nasal cyanocobalamin is typically used weekly for the treatment of pernicious anemia. It's administered into one nostril as directed by a healthcare provider. This method allows for the absorption of vitamin B12 through the nasal mucosa.
Choice D Reason:
Using a nasal decongestant before administering the medication is not typically part of the recommended administration protocol for nasal cyanocobalamin.
