A nurse is teaching a client who has a new prescription for colchicine to treat gout. Which of the following instructions should the nurse include?

Step 1 is to calculate the number of milliliters (mL) that contain the ordered dose of 300 mg of clindamycin.

Step 2 is to divide the total milliliters (mL) from Step 1 by the infusion time in minutes to get the flow rate in mL/hour. Here are the calculations:

Step 1:

900 mg of clindamycin is in 50 mL.

To find the mL that contain 300 mg, set up a proportion:

(300 mg / 900 mg) = (x mL / 50 mL) Cross-multiply and solve for x:

x = (300 mg * 50 mL) / 900 mg x = 16.67 mL

Step 2:

The infusion time is 30 minutes.

Divide the total mL (16.67 mL) by the infusion time in hours to get the flow rate in mL/hour: Flow rate = 16.67 mL / (30 minutes / 60 minutes/hour)

Flow rate = 33.33 mL/hour

Round to the nearest whole number, using a leading zero if it applies, and no trailing zero: Flow rate = 033 mL/hour

Choice A rationale:
Magnet activation: Placing a magnet over the implantable device activates an on-demand feature of the VNS, delivering extra stimulation to the vagus nerve. This can potentially disrupt or shorten a seizure, especially when used at the onset of an aura (a warning sign that a seizure may be imminent).
Patient empowerment: Teaching the patient how to use the magnet provides them with a sense of control and a way to actively manage their seizures. It can reduce anxiety and improve quality of life.
Choice B rationale:
Microwave safety: While there's no definitive evidence that microwaves directly interfere with VNS devices, manufacturers generally recommend avoiding close or prolonged exposure to microwaves as a precaution. Specific guidelines may vary, but they often suggest keeping a distance of at least 15-20 inches from microwaves. The statement in Choice B about 12,000 watts or less is inaccurate and misleading.
Choice C rationale:
CT scans with contrast: There's no contraindication for patients with VNS to undergo CT scans with contrast. The device is designed to withstand common imaging procedures.
Choice D rationale:
Pain management: Burst catheters are typically used for pain management after surgery or during childbirth. They have no direct relevance to VNS therapy or seizure management.
